GNU GENERAL PUBLIC LICENSE
|
|
||||||
Version 3, 29 June 2007
|
|
||||||
|
|
||||||
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
|
|
||||||
Everyone is permitted to copy and distribute verbatim copies
|
|
||||||
of this license document, but changing it is not allowed.
|
|
||||||
|
|
||||||
Preamble
|
|
||||||
|
|
||||||
The GNU General Public License is a free, copyleft license for
|
|
||||||
software and other kinds of works.
|
|
||||||
|
|
||||||
The licenses for most software and other practical works are designed
|
|
||||||
to take away your freedom to share and change the works. By contrast,
|
|
||||||
the GNU General Public License is intended to guarantee your freedom to
|
|
||||||
share and change all versions of a program--to make sure it remains free
|
|
||||||
software for all its users. We, the Free Software Foundation, use the
|
|
||||||
GNU General Public License for most of our software; it applies also to
|
|
||||||
any other work released this way by its authors. You can apply it to
|
|
||||||
your programs, too.
|
|
||||||
|
|
||||||
When we speak of free software, we are referring to freedom, not
|
|
||||||
price. Our General Public Licenses are designed to make sure that you
|
|
||||||
have the freedom to distribute copies of free software (and charge for
|
|
||||||
them if you wish), that you receive source code or can get it if you
|
|
||||||
want it, that you can change the software or use pieces of it in new
|
|
||||||
free programs, and that you know you can do these things.
|
|
||||||
|
|
||||||
To protect your rights, we need to prevent others from denying you
|
|
||||||
these rights or asking you to surrender the rights. Therefore, you have
|
|
||||||
certain responsibilities if you distribute copies of the software, or if
|
|
||||||
you modify it: responsibilities to respect the freedom of others.
|
|
||||||
|
|
||||||
For example, if you distribute copies of such a program, whether
|
|
||||||
gratis or for a fee, you must pass on to the recipients the same
|
|
||||||
freedoms that you received. You must make sure that they, too, receive
|
|
||||||
or can get the source code. And you must show them these terms so they
|
|
||||||
know their rights.
|
|
||||||
|
|
||||||
Developers that use the GNU GPL protect your rights with two steps:
|
|
||||||
(1) assert copyright on the software, and (2) offer you this License
|
|
||||||
giving you legal permission to copy, distribute and/or modify it.
|
|
||||||
|
|
||||||
For the developers' and authors' protection, the GPL clearly explains
|
|
||||||
that there is no warranty for this free software. For both users' and
|
|
||||||
authors' sake, the GPL requires that modified versions be marked as
|
|
||||||
changed, so that their problems will not be attributed erroneously to
|
|
||||||
authors of previous versions.
|
|
||||||
|
|
||||||
Some devices are designed to deny users access to install or run
|
|
||||||
modified versions of the software inside them, although the manufacturer
|
|
||||||
can do so. This is fundamentally incompatible with the aim of
|
|
||||||
protecting users' freedom to change the software. The systematic
|
|
||||||
pattern of such abuse occurs in the area of products for individuals to
|
|
||||||
use, which is precisely where it is most unacceptable. Therefore, we
|
|
||||||
have designed this version of the GPL to prohibit the practice for those
|
|
||||||
products. If such problems arise substantially in other domains, we
|
|
||||||
stand ready to extend this provision to those domains in future versions
|
|
||||||
of the GPL, as needed to protect the freedom of users.
|
|
||||||
|
|
||||||
Finally, every program is threatened constantly by software patents.
|
|
||||||
States should not allow patents to restrict development and use of
|
|
||||||
software on general-purpose computers, but in those that do, we wish to
|
|
||||||
avoid the special danger that patents applied to a free program could
|
|
||||||
make it effectively proprietary. To prevent this, the GPL assures that
|
|
||||||
patents cannot be used to render the program non-free.
|
|
||||||
|
|
||||||
The precise terms and conditions for copying, distribution and
|
|
||||||
modification follow.
|
|
||||||
|
|
||||||
TERMS AND CONDITIONS
|
|
||||||
|
|
||||||
0. Definitions.
|
|
||||||
|
|
||||||
"This License" refers to version 3 of the GNU General Public License.
|
|
||||||
|
|
||||||
"Copyright" also means copyright-like laws that apply to other kinds of
|
|
||||||
works, such as semiconductor masks.
|
|
||||||
|
|
||||||
"The Program" refers to any copyrightable work licensed under this
|
|
||||||
License. Each licensee is addressed as "you". "Licensees" and
|
|
||||||
"recipients" may be individuals or organizations.
|
|
||||||
|
|
||||||
To "modify" a work means to copy from or adapt all or part of the work
|
|
||||||
in a fashion requiring copyright permission, other than the making of an
|
|
||||||
exact copy. The resulting work is called a "modified version" of the
|
|
||||||
earlier work or a work "based on" the earlier work.
|
|
||||||
|
|
||||||
A "covered work" means either the unmodified Program or a work based
|
|
||||||
on the Program.
|
|
||||||
|
|
||||||
To "propagate" a work means to do anything with it that, without
|
|
||||||
permission, would make you directly or secondarily liable for
|
|
||||||
infringement under applicable copyright law, except executing it on a
|
|
||||||
computer or modifying a private copy. Propagation includes copying,
|
|
||||||
distribution (with or without modification), making available to the
|
|
||||||
public, and in some countries other activities as well.
|
|
||||||
|
|
||||||
To "convey" a work means any kind of propagation that enables other
|
|
||||||
parties to make or receive copies. Mere interaction with a user through
|
|
||||||
a computer network, with no transfer of a copy, is not conveying.
|
|
||||||
|
|
||||||
An interactive user interface displays "Appropriate Legal Notices"
|
|
||||||
to the extent that it includes a convenient and prominently visible
|
|
||||||
feature that (1) displays an appropriate copyright notice, and (2)
|
|
||||||
tells the user that there is no warranty for the work (except to the
|
|
||||||
extent that warranties are provided), that licensees may convey the
|
|
||||||
work under this License, and how to view a copy of this License. If
|
|
||||||
the interface presents a list of user commands or options, such as a
|
|
||||||
menu, a prominent item in the list meets this criterion.
|
|
||||||
|
|
||||||
1. Source Code.
|
|
||||||
|
|
||||||
The "source code" for a work means the preferred form of the work
|
|
||||||
for making modifications to it. "Object code" means any non-source
|
|
||||||
form of a work.
|
|
||||||
|
|
||||||
A "Standard Interface" means an interface that either is an official
|
|
||||||
standard defined by a recognized standards body, or, in the case of
|
|
||||||
interfaces specified for a particular programming language, one that
|
|
||||||
is widely used among developers working in that language.
|
|
||||||
|
|
||||||
The "System Libraries" of an executable work include anything, other
|
|
||||||
than the work as a whole, that (a) is included in the normal form of
|
|
||||||
packaging a Major Component, but which is not part of that Major
|
|
||||||
Component, and (b) serves only to enable use of the work with that
|
|
||||||
Major Component, or to implement a Standard Interface for which an
|
|
||||||
implementation is available to the public in source code form. A
|
|
||||||
"Major Component", in this context, means a major essential component
|
|
||||||
(kernel, window system, and so on) of the specific operating system
|
|
||||||
(if any) on which the executable work runs, or a compiler used to
|
|
||||||
produce the work, or an object code interpreter used to run it.
|
|
||||||
|
|
||||||
The "Corresponding Source" for a work in object code form means all
|
|
||||||
the source code needed to generate, install, and (for an executable
|
|
||||||
work) run the object code and to modify the work, including scripts to
|
|
||||||
control those activities. However, it does not include the work's
|
|
||||||
System Libraries, or general-purpose tools or generally available free
|
|
||||||
programs which are used unmodified in performing those activities but
|
|
||||||
which are not part of the work. For example, Corresponding Source
|
|
||||||
includes interface definition files associated with source files for
|
|
||||||
the work, and the source code for shared libraries and dynamically
|
|
||||||
linked subprograms that the work is specifically designed to require,
|
|
||||||
such as by intimate data communication or control flow between those
|
|
||||||
subprograms and other parts of the work.
|
|
||||||
|
|
||||||
The Corresponding Source need not include anything that users
|
|
||||||
can regenerate automatically from other parts of the Corresponding
|
|
||||||
Source.
|
|
||||||
|
|
||||||
The Corresponding Source for a work in source code form is that
|
|
||||||
same work.
|
|
||||||
|
|
||||||
2. Basic Permissions.
|
|
||||||
|
|
||||||
All rights granted under this License are granted for the term of
|
|
||||||
copyright on the Program, and are irrevocable provided the stated
|
|
||||||
conditions are met. This License explicitly affirms your unlimited
|
|
||||||
permission to run the unmodified Program. The output from running a
|
|
||||||
covered work is covered by this License only if the output, given its
|
|
||||||
content, constitutes a covered work. This License acknowledges your
|
|
||||||
rights of fair use or other equivalent, as provided by copyright law.
|
|
||||||
|
|
||||||
You may make, run and propagate covered works that you do not
|
|
||||||
convey, without conditions so long as your license otherwise remains
|
|
||||||
in force. You may convey covered works to others for the sole purpose
|
|
||||||
of having them make modifications exclusively for you, or provide you
|
|
||||||
with facilities for running those works, provided that you comply with
|
|
||||||
the terms of this License in conveying all material for which you do
|
|
||||||
not control copyright. Those thus making or running the covered works
|
|
||||||
for you must do so exclusively on your behalf, under your direction
|
|
||||||
and control, on terms that prohibit them from making any copies of
|
|
||||||
your copyrighted material outside their relationship with you.
|
|
||||||
|
|
||||||
Conveying under any other circumstances is permitted solely under
|
|
||||||
the conditions stated below. Sublicensing is not allowed; section 10
|
|
||||||
makes it unnecessary.
|
|
||||||
|
|
||||||
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
|
|
||||||
|
|
||||||
No covered work shall be deemed part of an effective technological
|
|
||||||
measure under any applicable law fulfilling obligations under article
|
|
||||||
11 of the WIPO copyright treaty adopted on 20 December 1996, or
|
|
||||||
similar laws prohibiting or restricting circumvention of such
|
|
||||||
measures.
|
|
||||||
|
|
||||||
When you convey a covered work, you waive any legal power to forbid
|
|
||||||
circumvention of technological measures to the extent such circumvention
|
|
||||||
is effected by exercising rights under this License with respect to
|
|
||||||
the covered work, and you disclaim any intention to limit operation or
|
|
||||||
modification of the work as a means of enforcing, against the work's
|
|
||||||
users, your or third parties' legal rights to forbid circumvention of
|
|
||||||
technological measures.
|
|
||||||
|
|
||||||
4. Conveying Verbatim Copies.
|
|
||||||
|
|
||||||
You may convey verbatim copies of the Program's source code as you
|
|
||||||
receive it, in any medium, provided that you conspicuously and
|
|
||||||
appropriately publish on each copy an appropriate copyright notice;
|
|
||||||
keep intact all notices stating that this License and any
|
|
||||||
non-permissive terms added in accord with section 7 apply to the code;
|
|
||||||
keep intact all notices of the absence of any warranty; and give all
|
|
||||||
recipients a copy of this License along with the Program.
|
|
||||||
|
|
||||||
You may charge any price or no price for each copy that you convey,
|
|
||||||
and you may offer support or warranty protection for a fee.
|
|
||||||
|
|
||||||
5. Conveying Modified Source Versions.
|
|
||||||
|
|
||||||
You may convey a work based on the Program, or the modifications to
|
|
||||||
produce it from the Program, in the form of source code under the
|
|
||||||
terms of section 4, provided that you also meet all of these conditions:
|
|
||||||
|
|
||||||
a) The work must carry prominent notices stating that you modified
|
|
||||||
it, and giving a relevant date.
|
|
||||||
|
|
||||||
b) The work must carry prominent notices stating that it is
|
|
||||||
released under this License and any conditions added under section
|
|
||||||
7. This requirement modifies the requirement in section 4 to
|
|
||||||
"keep intact all notices".
|
|
||||||
|
|
||||||
c) You must license the entire work, as a whole, under this
|
|
||||||
License to anyone who comes into possession of a copy. This
|
|
||||||
License will therefore apply, along with any applicable section 7
|
|
||||||
additional terms, to the whole of the work, and all its parts,
|
|
||||||
regardless of how they are packaged. This License gives no
|
|
||||||
permission to license the work in any other way, but it does not
|
|
||||||
invalidate such permission if you have separately received it.
|
|
||||||
|
|
||||||
d) If the work has interactive user interfaces, each must display
|
|
||||||
Appropriate Legal Notices; however, if the Program has interactive
|
|
||||||
interfaces that do not display Appropriate Legal Notices, your
|
|
||||||
work need not make them do so.
|
|
||||||
|
|
||||||
A compilation of a covered work with other separate and independent
|
|
||||||
works, which are not by their nature extensions of the covered work,
|
|
||||||
and which are not combined with it such as to form a larger program,
|
|
||||||
in or on a volume of a storage or distribution medium, is called an
|
|
||||||
"aggregate" if the compilation and its resulting copyright are not
|
|
||||||
used to limit the access or legal rights of the compilation's users
|
|
||||||
beyond what the individual works permit. Inclusion of a covered work
|
|
||||||
in an aggregate does not cause this License to apply to the other
|
|
||||||
parts of the aggregate.
|
|
||||||
|
|
||||||
6. Conveying Non-Source Forms.
|
|
||||||
|
|
||||||
You may convey a covered work in object code form under the terms
|
|
||||||
of sections 4 and 5, provided that you also convey the
|
|
||||||
machine-readable Corresponding Source under the terms of this License,
|
|
||||||
in one of these ways:
|
|
||||||
|
|
||||||
a) Convey the object code in, or embodied in, a physical product
|
|
||||||
(including a physical distribution medium), accompanied by the
|
|
||||||
Corresponding Source fixed on a durable physical medium
|
|
||||||
customarily used for software interchange.
|
|
||||||
|
|
||||||
b) Convey the object code in, or embodied in, a physical product
|
|
||||||
(including a physical distribution medium), accompanied by a
|
|
||||||
written offer, valid for at least three years and valid for as
|
|
||||||
long as you offer spare parts or customer support for that product
|
|
||||||
model, to give anyone who possesses the object code either (1) a
|
|
||||||
copy of the Corresponding Source for all the software in the
|
|
||||||
product that is covered by this License, on a durable physical
|
|
||||||
medium customarily used for software interchange, for a price no
|
|
||||||
more than your reasonable cost of physically performing this
|
|
||||||
conveying of source, or (2) access to copy the
|
|
||||||
Corresponding Source from a network server at no charge.
|
|
||||||
|
|
||||||
c) Convey individual copies of the object code with a copy of the
|
|
||||||
written offer to provide the Corresponding Source. This
|
|
||||||
alternative is allowed only occasionally and noncommercially, and
|
|
||||||
only if you received the object code with such an offer, in accord
|
|
||||||
with subsection 6b.
|
|
||||||
|
|
||||||
d) Convey the object code by offering access from a designated
|
|
||||||
place (gratis or for a charge), and offer equivalent access to the
|
|
||||||
Corresponding Source in the same way through the same place at no
|
|
||||||
further charge. You need not require recipients to copy the
|
|
||||||
Corresponding Source along with the object code. If the place to
|
|
||||||
copy the object code is a network server, the Corresponding Source
|
|
||||||
may be on a different server (operated by you or a third party)
|
|
||||||
that supports equivalent copying facilities, provided you maintain
|
|
||||||
clear directions next to the object code saying where to find the
|
|
||||||
Corresponding Source. Regardless of what server hosts the
|
|
||||||
Corresponding Source, you remain obligated to ensure that it is
|
|
||||||
available for as long as needed to satisfy these requirements.
|
|
||||||
|
|
||||||
e) Convey the object code using peer-to-peer transmission, provided
|
|
||||||
you inform other peers where the object code and Corresponding
|
|
||||||
Source of the work are being offered to the general public at no
|
|
||||||
charge under subsection 6d.
|
|
||||||
|
|
||||||
A separable portion of the object code, whose source code is excluded
|
|
||||||
from the Corresponding Source as a System Library, need not be
|
|
||||||
included in conveying the object code work.
|
|
||||||
|
|
||||||
A "User Product" is either (1) a "consumer product", which means any
|
|
||||||
tangible personal property which is normally used for personal, family,
|
|
||||||
or household purposes, or (2) anything designed or sold for incorporation
|
|
||||||
into a dwelling. In determining whether a product is a consumer product,
|
|
||||||
doubtful cases shall be resolved in favor of coverage. For a particular
|
|
||||||
product received by a particular user, "normally used" refers to a
|
|
||||||
typical or common use of that class of product, regardless of the status
|
|
||||||
of the particular user or of the way in which the particular user
|
|
||||||
actually uses, or expects or is expected to use, the product. A product
|
|
||||||
is a consumer product regardless of whether the product has substantial
|
|
||||||
commercial, industrial or non-consumer uses, unless such uses represent
|
|
||||||
the only significant mode of use of the product.
|
|
||||||
|
|
||||||
"Installation Information" for a User Product means any methods,
|
|
||||||
procedures, authorization keys, or other information required to install
|
|
||||||
and execute modified versions of a covered work in that User Product from
|
|
||||||
a modified version of its Corresponding Source. The information must
|
|
||||||
suffice to ensure that the continued functioning of the modified object
|
|
||||||
code is in no case prevented or interfered with solely because
|
|
||||||
modification has been made.
|
|
||||||
|
|
||||||
If you convey an object code work under this section in, or with, or
|
|
||||||
specifically for use in, a User Product, and the conveying occurs as
|
|
||||||
part of a transaction in which the right of possession and use of the
|
|
||||||
User Product is transferred to the recipient in perpetuity or for a
|
|
||||||
fixed term (regardless of how the transaction is characterized), the
|
|
||||||
Corresponding Source conveyed under this section must be accompanied
|
|
||||||
by the Installation Information. But this requirement does not apply
|
|
||||||
if neither you nor any third party retains the ability to install
|
|
||||||
modified object code on the User Product (for example, the work has
|
|
||||||
been installed in ROM).
|
|
||||||
|
|
||||||
The requirement to provide Installation Information does not include a
|
|
||||||
requirement to continue to provide support service, warranty, or updates
|
|
||||||
for a work that has been modified or installed by the recipient, or for
|
|
||||||
the User Product in which it has been modified or installed. Access to a
|
|
||||||
network may be denied when the modification itself materially and
|
|
||||||
adversely affects the operation of the network or violates the rules and
|
|
||||||
protocols for communication across the network.
|
|
||||||
|
|
||||||
Corresponding Source conveyed, and Installation Information provided,
|
|
||||||
in accord with this section must be in a format that is publicly
|
|
||||||
documented (and with an implementation available to the public in
|
|
||||||
source code form), and must require no special password or key for
|
|
||||||
unpacking, reading or copying.
|
|
||||||
|
|
||||||
7. Additional Terms.
|
|
||||||
|
|
||||||
"Additional permissions" are terms that supplement the terms of this
|
|
||||||
License by making exceptions from one or more of its conditions.
|
|
||||||
Additional permissions that are applicable to the entire Program shall
|
|
||||||
be treated as though they were included in this License, to the extent
|
|
||||||
that they are valid under applicable law. If additional permissions
|
|
||||||
apply only to part of the Program, that part may be used separately
|
|
||||||
under those permissions, but the entire Program remains governed by
|
|
||||||
this License without regard to the additional permissions.
|
|
||||||
|
|
||||||
When you convey a copy of a covered work, you may at your option
|
|
||||||
remove any additional permissions from that copy, or from any part of
|
|
||||||
it. (Additional permissions may be written to require their own
|
|
||||||
removal in certain cases when you modify the work.) You may place
|
|
||||||
additional permissions on material, added by you to a covered work,
|
|
||||||
for which you have or can give appropriate copyright permission.
|
|
||||||
|
|
||||||
Notwithstanding any other provision of this License, for material you
|
|
||||||
add to a covered work, you may (if authorized by the copyright holders of
|
|
||||||
that material) supplement the terms of this License with terms:
|
|
||||||
|
|
||||||
a) Disclaiming warranty or limiting liability differently from the
|
|
||||||
terms of sections 15 and 16 of this License; or
|
|
||||||
|
|
||||||
b) Requiring preservation of specified reasonable legal notices or
|
|
||||||
author attributions in that material or in the Appropriate Legal
|
|
||||||
Notices displayed by works containing it; or
|
|
||||||
|
|
||||||
c) Prohibiting misrepresentation of the origin of that material, or
|
|
||||||
requiring that modified versions of such material be marked in
|
|
||||||
reasonable ways as different from the original version; or
|
|
||||||
|
|
||||||
d) Limiting the use for publicity purposes of names of licensors or
|
|
||||||
authors of the material; or
|
|
||||||
|
|
||||||
e) Declining to grant rights under trademark law for use of some
|
|
||||||
trade names, trademarks, or service marks; or
|
|
||||||
|
|
||||||
f) Requiring indemnification of licensors and authors of that
|
|
||||||
material by anyone who conveys the material (or modified versions of
|
|
||||||
it) with contractual assumptions of liability to the recipient, for
|
|
||||||
any liability that these contractual assumptions directly impose on
|
|
||||||
those licensors and authors.
|
|
||||||
|
|
||||||
All other non-permissive additional terms are considered "further
|
|
||||||
restrictions" within the meaning of section 10. If the Program as you
|
|
||||||
received it, or any part of it, contains a notice stating that it is
|
|
||||||
governed by this License along with a term that is a further
|
|
||||||
restriction, you may remove that term. If a license document contains
|
|
||||||
a further restriction but permits relicensing or conveying under this
|
|
||||||
License, you may add to a covered work material governed by the terms
|
|
||||||
of that license document, provided that the further restriction does
|
|
||||||
not survive such relicensing or conveying.
|
|
||||||
|
|
||||||
If you add terms to a covered work in accord with this section, you
|
|
||||||
must place, in the relevant source files, a statement of the
|
|
||||||
additional terms that apply to those files, or a notice indicating
|
|
||||||
where to find the applicable terms.
|
|
||||||
|
|
||||||
Additional terms, permissive or non-permissive, may be stated in the
|
|
||||||
form of a separately written license, or stated as exceptions;
|
|
||||||
the above requirements apply either way.
|
|
||||||
|
|
||||||
8. Termination.
|
|
||||||
|
|
||||||
You may not propagate or modify a covered work except as expressly
|
|
||||||
provided under this License. Any attempt otherwise to propagate or
|
|
||||||
modify it is void, and will automatically terminate your rights under
|
|
||||||
this License (including any patent licenses granted under the third
|
|
||||||
paragraph of section 11).
|
|
||||||
|
|
||||||
However, if you cease all violation of this License, then your
|
|
||||||
license from a particular copyright holder is reinstated (a)
|
|
||||||
provisionally, unless and until the copyright holder explicitly and
|
|
||||||
finally terminates your license, and (b) permanently, if the copyright
|
|
||||||
holder fails to notify you of the violation by some reasonable means
|
|
||||||
prior to 60 days after the cessation.
|
|
||||||
|
|
||||||
Moreover, your license from a particular copyright holder is
|
|
||||||
reinstated permanently if the copyright holder notifies you of the
|
|
||||||
violation by some reasonable means, this is the first time you have
|
|
||||||
received notice of violation of this License (for any work) from that
|
|
||||||
copyright holder, and you cure the violation prior to 30 days after
|
|
||||||
your receipt of the notice.
|
|
||||||
|
|
||||||
Termination of your rights under this section does not terminate the
|
|
||||||
licenses of parties who have received copies or rights from you under
|
|
||||||
this License. If your rights have been terminated and not permanently
|
|
||||||
reinstated, you do not qualify to receive new licenses for the same
|
|
||||||
material under section 10.
|
|
||||||
|
|
||||||
9. Acceptance Not Required for Having Copies.
|
|
||||||
|
|
||||||
You are not required to accept this License in order to receive or
|
|
||||||
run a copy of the Program. Ancillary propagation of a covered work
|
|
||||||
occurring solely as a consequence of using peer-to-peer transmission
|
|
||||||
to receive a copy likewise does not require acceptance. However,
|
|
||||||
nothing other than this License grants you permission to propagate or
|
|
||||||
modify any covered work. These actions infringe copyright if you do
|
|
||||||
not accept this License. Therefore, by modifying or propagating a
|
|
||||||
covered work, you indicate your acceptance of this License to do so.
|
|
||||||
|
|
||||||
10. Automatic Licensing of Downstream Recipients.
|
|
||||||
|
|
||||||
Each time you convey a covered work, the recipient automatically
|
|
||||||
receives a license from the original licensors, to run, modify and
|
|
||||||
propagate that work, subject to this License. You are not responsible
|
|
||||||
for enforcing compliance by third parties with this License.
|
|
||||||
|
|
||||||
An "entity transaction" is a transaction transferring control of an
|
|
||||||
organization, or substantially all assets of one, or subdividing an
|
|
||||||
organization, or merging organizations. If propagation of a covered
|
|
||||||
work results from an entity transaction, each party to that
|
|
||||||
transaction who receives a copy of the work also receives whatever
|
|
||||||
licenses to the work the party's predecessor in interest had or could
|
|
||||||
give under the previous paragraph, plus a right to possession of the
|
|
||||||
Corresponding Source of the work from the predecessor in interest, if
|
|
||||||
the predecessor has it or can get it with reasonable efforts.
|
|
||||||
|
|
||||||
You may not impose any further restrictions on the exercise of the
|
|
||||||
rights granted or affirmed under this License. For example, you may
|
|
||||||
not impose a license fee, royalty, or other charge for exercise of
|
|
||||||
rights granted under this License, and you may not initiate litigation
|
|
||||||
(including a cross-claim or counterclaim in a lawsuit) alleging that
|
|
||||||
any patent claim is infringed by making, using, selling, offering for
|
|
||||||
sale, or importing the Program or any portion of it.
|
|
||||||
|
|
||||||
11. Patents.
|
|
||||||
|
|
||||||
A "contributor" is a copyright holder who authorizes use under this
|
|
||||||
License of the Program or a work on which the Program is based. The
|
|
||||||
work thus licensed is called the contributor's "contributor version".
|
|
||||||
|
|
||||||
A contributor's "essential patent claims" are all patent claims
|
|
||||||
owned or controlled by the contributor, whether already acquired or
|
|
||||||
hereafter acquired, that would be infringed by some manner, permitted
|
|
||||||
by this License, of making, using, or selling its contributor version,
|
|
||||||
but do not include claims that would be infringed only as a
|
|
||||||
consequence of further modification of the contributor version. For
|
|
||||||
purposes of this definition, "control" includes the right to grant
|
|
||||||
patent sublicenses in a manner consistent with the requirements of
|
|
||||||
this License.
|
|
||||||
|
|
||||||
Each contributor grants you a non-exclusive, worldwide, royalty-free
|
|
||||||
patent license under the contributor's essential patent claims, to
|
|
||||||
make, use, sell, offer for sale, import and otherwise run, modify and
|
|
||||||
propagate the contents of its contributor version.
|
|
||||||
|
|
||||||
In the following three paragraphs, a "patent license" is any express
|
|
||||||
agreement or commitment, however denominated, not to enforce a patent
|
|
||||||
(such as an express permission to practice a patent or covenant not to
|
|
||||||
sue for patent infringement). To "grant" such a patent license to a
|
|
||||||
party means to make such an agreement or commitment not to enforce a
|
|
||||||
patent against the party.
|
|
||||||
|
|
||||||
If you convey a covered work, knowingly relying on a patent license,
|
|
||||||
and the Corresponding Source of the work is not available for anyone
|
|
||||||
to copy, free of charge and under the terms of this License, through a
|
|
||||||
publicly available network server or other readily accessible means,
|
|
||||||
then you must either (1) cause the Corresponding Source to be so
|
|
||||||
available, or (2) arrange to deprive yourself of the benefit of the
|
|
||||||
patent license for this particular work, or (3) arrange, in a manner
|
|
||||||
consistent with the requirements of this License, to extend the patent
|
|
||||||
license to downstream recipients. "Knowingly relying" means you have
|
|
||||||
actual knowledge that, but for the patent license, your conveying the
|
|
||||||
covered work in a country, or your recipient's use of the covered work
|
|
||||||
in a country, would infringe one or more identifiable patents in that
|
|
||||||
country that you have reason to believe are valid.
|
|
||||||
|
|
||||||
If, pursuant to or in connection with a single transaction or
|
|
||||||
arrangement, you convey, or propagate by procuring conveyance of, a
|
|
||||||
covered work, and grant a patent license to some of the parties
|
|
||||||
receiving the covered work authorizing them to use, propagate, modify
|
|
||||||
or convey a specific copy of the covered work, then the patent license
|
|
||||||
you grant is automatically extended to all recipients of the covered
|
|
||||||
work and works based on it.
|
|
||||||
|
|
||||||
A patent license is "discriminatory" if it does not include within
|
|
||||||
the scope of its coverage, prohibits the exercise of, or is
|
|
||||||
conditioned on the non-exercise of one or more of the rights that are
|
|
||||||
specifically granted under this License. You may not convey a covered
|
|
||||||
work if you are a party to an arrangement with a third party that is
|
|
||||||
in the business of distributing software, under which you make payment
|
|
||||||
to the third party based on the extent of your activity of conveying
|
|
||||||
the work, and under which the third party grants, to any of the
|
|
||||||
parties who would receive the covered work from you, a discriminatory
|
|
||||||
patent license (a) in connection with copies of the covered work
|
|
||||||
conveyed by you (or copies made from those copies), or (b) primarily
|
|
||||||
for and in connection with specific products or compilations that
|
|
||||||
contain the covered work, unless you entered into that arrangement,
|
|
||||||
or that patent license was granted, prior to 28 March 2007.
|
|
||||||
|
|
||||||
Nothing in this License shall be construed as excluding or limiting
|
|
||||||
any implied license or other defenses to infringement that may
|
|
||||||
otherwise be available to you under applicable patent law.
|
|
||||||
|
|
||||||
12. No Surrender of Others' Freedom.
|
|
||||||
|
|
||||||
If conditions are imposed on you (whether by court order, agreement or
|
|
||||||
otherwise) that contradict the conditions of this License, they do not
|
|
||||||
excuse you from the conditions of this License. If you cannot convey a
|
|
||||||
covered work so as to satisfy simultaneously your obligations under this
|
|
||||||
License and any other pertinent obligations, then as a consequence you may
|
|
||||||
not convey it at all. For example, if you agree to terms that obligate you
|
|
||||||
to collect a royalty for further conveying from those to whom you convey
|
|
||||||
the Program, the only way you could satisfy both those terms and this
|
|
||||||
License would be to refrain entirely from conveying the Program.
|
|
||||||
|
|
||||||
13. Use with the GNU Affero General Public License.
|
|
||||||
|
|
||||||
Notwithstanding any other provision of this License, you have
|
|
||||||
permission to link or combine any covered work with a work licensed
|
|
||||||
under version 3 of the GNU Affero General Public License into a single
|
|
||||||
combined work, and to convey the resulting work. The terms of this
|
|
||||||
License will continue to apply to the part which is the covered work,
|
|
||||||
but the special requirements of the GNU Affero General Public License,
|
|
||||||
section 13, concerning interaction through a network will apply to the
|
|
||||||
combination as such.
|
|
||||||
|
|
||||||
14. Revised Versions of this License.
|
|
||||||
|
|
||||||
The Free Software Foundation may publish revised and/or new versions of
|
|
||||||
the GNU General Public License from time to time. Such new versions will
|
|
||||||
be similar in spirit to the present version, but may differ in detail to
|
|
||||||
address new problems or concerns.
|
|
||||||
|
|
||||||
Each version is given a distinguishing version number. If the
|
|
||||||
Program specifies that a certain numbered version of the GNU General
|
|
||||||
Public License "or any later version" applies to it, you have the
|
|
||||||
option of following the terms and conditions either of that numbered
|
|
||||||
version or of any later version published by the Free Software
|
|
||||||
Foundation. If the Program does not specify a version number of the
|
|
||||||
GNU General Public License, you may choose any version ever published
|
|
||||||
by the Free Software Foundation.
|
|
||||||
|
|
||||||
If the Program specifies that a proxy can decide which future
|
|
||||||
versions of the GNU General Public License can be used, that proxy's
|
|
||||||
public statement of acceptance of a version permanently authorizes you
|
|
||||||
to choose that version for the Program.
|
|
||||||
|
|
||||||
Later license versions may give you additional or different
|
|
||||||
permissions. However, no additional obligations are imposed on any
|
|
||||||
author or copyright holder as a result of your choosing to follow a
|
|
||||||
later version.
|
|
||||||
|
|
||||||
15. Disclaimer of Warranty.
|
|
||||||
|
|
||||||
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
|
|
||||||
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
|
|
||||||
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
|
|
||||||
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
|
|
||||||
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
|
||||||
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
|
|
||||||
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
|
|
||||||
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
|
||||||
|
|
||||||
16. Limitation of Liability.
|
|
||||||
|
|
||||||
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
|
||||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
|
|
||||||
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
|
|
||||||
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
|
|
||||||
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
|
|
||||||
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
|
|
||||||
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
|
|
||||||
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
|
|
||||||
SUCH DAMAGES.
|
|
||||||
|
|
||||||
17. Interpretation of Sections 15 and 16.
|
|
||||||
|
|
||||||
If the disclaimer of warranty and limitation of liability provided
|
|
||||||
above cannot be given local legal effect according to their terms,
|
|
||||||
reviewing courts shall apply local law that most closely approximates
|
|
||||||
an absolute waiver of all civil liability in connection with the
|
|
||||||
Program, unless a warranty or assumption of liability accompanies a
|
|
||||||
copy of the Program in return for a fee.
|
|
||||||
|
|
||||||
END OF TERMS AND CONDITIONS
|
|
||||||
|
|
||||||
How to Apply These Terms to Your New Programs
|
|
||||||
|
|
||||||
If you develop a new program, and you want it to be of the greatest
|
|
||||||
possible use to the public, the best way to achieve this is to make it
|
|
||||||
free software which everyone can redistribute and change under these terms.
|
|
||||||
|
|
||||||
To do so, attach the following notices to the program. It is safest
|
|
||||||
to attach them to the start of each source file to most effectively
|
|
||||||
state the exclusion of warranty; and each file should have at least
|
|
||||||
the "copyright" line and a pointer to where the full notice is found.
|
|
||||||
|
|
||||||
<one line to give the program's name and a brief idea of what it does.>
|
|
||||||
Copyright (C) <year> <name of author>
|
|
||||||
|
|
||||||
This program is free software: you can redistribute it and/or modify
|
|
||||||
it under the terms of the GNU General Public License as published by
|
|
||||||
the Free Software Foundation, either version 3 of the License, or
|
|
||||||
(at your option) any later version.
|
|
||||||
|
|
||||||
This program is distributed in the hope that it will be useful,
|
|
||||||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
|
||||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
|
||||||
GNU General Public License for more details.
|
|
||||||
|
|
||||||
You should have received a copy of the GNU General Public License
|
|
||||||
along with this program. If not, see <http://www.gnu.org/licenses/>.
|
|
||||||
|
|
||||||
Also add information on how to contact you by electronic and paper mail.
|
|
||||||
|
|
||||||
If the program does terminal interaction, make it output a short
|
|
||||||
notice like this when it starts in an interactive mode:
|
|
||||||
|
|
||||||
<program> Copyright (C) <year> <name of author>
|
|
||||||
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
|
||||||
This is free software, and you are welcome to redistribute it
|
|
||||||
under certain conditions; type `show c' for details.
|
|
||||||
|
|
||||||
The hypothetical commands `show w' and `show c' should show the appropriate
|
|
||||||
parts of the General Public License. Of course, your program's commands
|
|
||||||
might be different; for a GUI interface, you would use an "about box".
|
|
||||||
|
|
||||||
You should also get your employer (if you work as a programmer) or school,
|
|
||||||
if any, to sign a "copyright disclaimer" for the program, if necessary.
|
|
||||||

|
|
||||||
<http://www.gnu.org/licenses/>.
|
|
||||||
|
|
||||||
The GNU General Public License does not permit incorporating your program
|
|
||||||
into proprietary programs. If your program is a subroutine library, you
|
|
||||||
may consider it more useful to permit linking proprietary applications with
|
|
||||||
the library. If this is what you want to do, use the GNU Lesser General
|
|
||||||
Public License instead of this License. But first, please read

[This is the first released version of the Lesser GPL. It also counts
|
||||||
|
as the successor of the GNU Library Public License, version 2, hence
|
||||||
|
the version number 2.1.]
|
||||||
|
|
||||||
|
Preamble
|
||||||
|
|
||||||
|
The licenses for most software are designed to take away your
|
||||||
|
freedom to share and change it. By contrast, the GNU General Public
|
||||||
|
Licenses are intended to guarantee your freedom to share and change
|
||||||
|
free software--to make sure the software is free for all its users.
|
||||||
|
|
||||||
|
This license, the Lesser General Public License, applies to some
|
||||||
|
specially designated software packages--typically libraries--of the
|
||||||
|
Free Software Foundation and other authors who decide to use it. You
|
||||||
|
can use it too, but we suggest you first think carefully about whether
|
||||||
|
this license or the ordinary General Public License is the better
|
||||||
|
strategy to use in any particular case, based on the explanations below.
|
||||||
|
|
||||||
|
When we speak of free software, we are referring to freedom of use,
|
||||||
|
not price. Our General Public Licenses are designed to make sure that
|
||||||
|
you have the freedom to distribute copies of free software (and charge
|
||||||
|
for this service if you wish); that you receive source code or can get
|
||||||
|
it if you want it; that you can change the software and use pieces of
|
||||||
|
it in new free programs; and that you are informed that you can do
|
||||||
|
these things.
|
||||||
|
|
||||||
|
To protect your rights, we need to make restrictions that forbid
|
||||||
|
distributors to deny you these rights or to ask you to surrender these
|
||||||
|
rights. These restrictions translate to certain responsibilities for
|
||||||
|
you if you distribute copies of the library or if you modify it.
|
||||||
|
|
||||||
|
For example, if you distribute copies of the library, whether gratis
|
||||||
|
or for a fee, you must give the recipients all the rights that we gave
|
||||||
|
you. You must make sure that they, too, receive or can get the source
|
||||||
|
code. If you link other code with the library, you must provide
|
||||||
|
complete object files to the recipients, so that they can relink them
|
||||||
|
with the library after making changes to the library and recompiling
|
||||||
|
it. And you must show them these terms so they know their rights.
|
||||||
|
|
||||||
|
We protect your rights with a two-step method: (1) we copyright the
|
||||||
|
library, and (2) we offer you this license, which gives you legal
|
||||||
|
permission to copy, distribute and/or modify the library.
|
||||||
|
|
||||||
|
To protect each distributor, we want to make it very clear that
|
||||||
|
there is no warranty for the free library. Also, if the library is
|
||||||
|
modified by someone else and passed on, the recipients should know
|
||||||
|
that what they have is not the original version, so that the original
|
||||||
|
author's reputation will not be affected by problems that might be
|
||||||
|
introduced by others.
|
||||||
|
|
||||||
|
Finally, software patents pose a constant threat to the existence of
|
||||||
|
any free program. We wish to make sure that a company cannot
|
||||||
|
effectively restrict the users of a free program by obtaining a
|
||||||
|
restrictive license from a patent holder. Therefore, we insist that
|
||||||
|
any patent license obtained for a version of the library must be
|
||||||
|
consistent with the full freedom of use specified in this license.
|
||||||
|
|
||||||
|
Most GNU software, including some libraries, is covered by the
|
||||||
|
ordinary GNU General Public License. This license, the GNU Lesser
|
||||||
|
General Public License, applies to certain designated libraries, and
|
||||||
|
is quite different from the ordinary General Public License. We use
|
||||||
|
this license for certain libraries in order to permit linking those
|
||||||
|
libraries into non-free programs.
|
||||||
|
|
||||||
|
When a program is linked with a library, whether statically or using
|
||||||
|
a shared library, the combination of the two is legally speaking a
|
||||||
|
combined work, a derivative of the original library. The ordinary
|
||||||
|
General Public License therefore permits such linking only if the
|
||||||
|
entire combination fits its criteria of freedom. The Lesser General
|
||||||
|
Public License permits more lax criteria for linking other code with
|
||||||
|
the library.
|
||||||
|
|
||||||
|
We call this license the "Lesser" General Public License because it
|
||||||
|
does Less to protect the user's freedom than the ordinary General
|
||||||
|
Public License. It also provides other free software developers Less
|
||||||
|
of an advantage over competing non-free programs. These disadvantages
|
||||||
|
are the reason we use the ordinary General Public License for many
|
||||||
|
libraries. However, the Lesser license provides advantages in certain
|
||||||
|
special circumstances.
|
||||||
|
|
||||||
|
For example, on rare occasions, there may be a special need to
|
||||||
|
encourage the widest possible use of a certain library, so that it becomes
|
||||||
|
a de-facto standard. To achieve this, non-free programs must be
|
||||||
|
allowed to use the library. A more frequent case is that a free
|
||||||
|
library does the same job as widely used non-free libraries. In this
|
||||||
|
case, there is little to gain by limiting the free library to free
|
||||||
|
software only, so we use the Lesser General Public License.
|
||||||
|
|
||||||
|
In other cases, permission to use a particular library in non-free
|
||||||
|
programs enables a greater number of people to use a large body of
|
||||||
|
free software. For example, permission to use the GNU C Library in
|
||||||
|
non-free programs enables many more people to use the whole GNU
|
||||||
|
operating system, as well as its variant, the GNU/Linux operating
|
||||||
|
system.
|
||||||
|
|
||||||
|
Although the Lesser General Public License is Less protective of the
|
||||||
|
users' freedom, it does ensure that the user of a program that is
|
||||||
|
linked with the Library has the freedom and the wherewithal to run
|
||||||
|
that program using a modified version of the Library.
|
||||||
|
|
||||||
|
The precise terms and conditions for copying, distribution and
|
||||||
|
modification follow. Pay close attention to the difference between a
|
||||||
|
"work based on the library" and a "work that uses the library". The
|
||||||
|
former contains code derived from the library, whereas the latter must
|
||||||
|
be combined with the library in order to run.
|
||||||
|
|
||||||
|
GNU LESSER GENERAL PUBLIC LICENSE
|
||||||
|
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||||
|
|
||||||
|
0. This License Agreement applies to any software library or other
|
||||||
|
program which contains a notice placed by the copyright holder or
|
||||||
|
other authorized party saying it may be distributed under the terms of
|
||||||
|
this Lesser General Public License (also called "this License").
|
||||||
|
Each licensee is addressed as "you".
|
||||||
|
|
||||||
|
A "library" means a collection of software functions and/or data
|
||||||
|
prepared so as to be conveniently linked with application programs
|
||||||
|
(which use some of those functions and data) to form executables.
|
||||||
|
|
||||||
|
The "Library", below, refers to any such software library or work
|
||||||
|
which has been distributed under these terms. A "work based on the
|
||||||
|
Library" means either the Library or any derivative work under
|
||||||
|
copyright law: that is to say, a work containing the Library or a
|
||||||
|
portion of it, either verbatim or with modifications and/or translated
|
||||||
|
straightforwardly into another language. (Hereinafter, translation is
|
||||||
|
included without limitation in the term "modification".)
|
||||||
|
|
||||||
|
"Source code" for a work means the preferred form of the work for
|
||||||
|
making modifications to it. For a library, complete source code means
|
||||||
|
all the source code for all modules it contains, plus any associated
|
||||||
|
interface definition files, plus the scripts used to control compilation
|
||||||
|
and installation of the library.
|
||||||
|
|
||||||
|
Activities other than copying, distribution and modification are not
|
||||||
|
covered by this License; they are outside its scope. The act of
|
||||||
|
running a program using the Library is not restricted, and output from
|
||||||
|
such a program is covered only if its contents constitute a work based
|
||||||
|
on the Library (independent of the use of the Library in a tool for
|
||||||
|
writing it). Whether that is true depends on what the Library does
|
||||||
|
and what the program that uses the Library does.
|
||||||
|
|
||||||
|
1. You may copy and distribute verbatim copies of the Library's
|
||||||
|
complete source code as you receive it, in any medium, provided that
|
||||||
|
you conspicuously and appropriately publish on each copy an
|
||||||
|
appropriate copyright notice and disclaimer of warranty; keep intact
|
||||||
|
all the notices that refer to this License and to the absence of any
|
||||||
|
warranty; and distribute a copy of this License along with the
|
||||||
|
Library.
|
||||||
|
|
||||||
|
You may charge a fee for the physical act of transferring a copy,
|
||||||
|
and you may at your option offer warranty protection in exchange for a
|
||||||
|
fee.
|
||||||
|
|
||||||
|
2. You may modify your copy or copies of the Library or any portion
|
||||||
|
of it, thus forming a work based on the Library, and copy and
|
||||||
|
distribute such modifications or work under the terms of Section 1
|
||||||
|
above, provided that you also meet all of these conditions:
|
||||||
|
|
||||||
|
a) The modified work must itself be a software library.
|
||||||
|
|
||||||
|
b) You must cause the files modified to carry prominent notices
|
||||||
|
stating that you changed the files and the date of any change.
|
||||||
|
|
||||||
|
c) You must cause the whole of the work to be licensed at no
|
||||||
|
charge to all third parties under the terms of this License.
|
||||||
|
|
||||||
|
d) If a facility in the modified Library refers to a function or a
|
||||||
|
table of data to be supplied by an application program that uses
|
||||||
|
the facility, other than as an argument passed when the facility
|
||||||
|
is invoked, then you must make a good faith effort to ensure that,
|
||||||
|
in the event an application does not supply such function or
|
||||||
|
table, the facility still operates, and performs whatever part of
|
||||||
|
its purpose remains meaningful.
|
||||||
|
|
||||||
|
(For example, a function in a library to compute square roots has
|
||||||
|
a purpose that is entirely well-defined independent of the
|
||||||
|
application. Therefore, Subsection 2d requires that any
|
||||||
|
application-supplied function or table used by this function must
|
||||||
|
be optional: if the application does not supply it, the square
|
||||||
|
root function must still compute square roots.)
|
||||||
|
|
||||||
|
These requirements apply to the modified work as a whole. If
|
||||||
|
identifiable sections of that work are not derived from the Library,
|
||||||
|
and can be reasonably considered independent and separate works in
|
||||||
|
themselves, then this License, and its terms, do not apply to those
|
||||||
|
sections when you distribute them as separate works. But when you
|
||||||
|
distribute the same sections as part of a whole which is a work based
|
||||||
|
on the Library, the distribution of the whole must be on the terms of
|
||||||
|
this License, whose permissions for other licensees extend to the
|
||||||
|
entire whole, and thus to each and every part regardless of who wrote
|
||||||
|
it.
|
||||||
|
|
||||||
|
Thus, it is not the intent of this section to claim rights or contest
|
||||||
|
your rights to work written entirely by you; rather, the intent is to
|
||||||
|
exercise the right to control the distribution of derivative or
|
||||||
|
collective works based on the Library.
|
||||||
|
|
||||||
|
In addition, mere aggregation of another work not based on the Library
|
||||||
|
with the Library (or with a work based on the Library) on a volume of
|
||||||
|
a storage or distribution medium does not bring the other work under
|
||||||
|
the scope of this License.
|
||||||
|
|
||||||
|
3. You may opt to apply the terms of the ordinary GNU General Public
|
||||||
|
License instead of this License to a given copy of the Library. To do
|
||||||
|
this, you must alter all the notices that refer to this License, so
|
||||||
|
that they refer to the ordinary GNU General Public License, version 2,
|
||||||
|
instead of to this License. (If a newer version than version 2 of the
|
||||||
|
ordinary GNU General Public License has appeared, then you can specify
|
||||||
|
that version instead if you wish.) Do not make any other change in
|
||||||
|
these notices.
|
||||||
|
|
||||||
|
Once this change is made in a given copy, it is irreversible for
|
||||||
|
that copy, so the ordinary GNU General Public License applies to all
|
||||||
|
subsequent copies and derivative works made from that copy.
|
||||||
|
|
||||||
|
This option is useful when you wish to copy part of the code of
|
||||||
|
the Library into a program that is not a library.
|
||||||
|
|
||||||
|
4. You may copy and distribute the Library (or a portion or
|
||||||
|
derivative of it, under Section 2) in object code or executable form
|
||||||
|
under the terms of Sections 1 and 2 above provided that you accompany
|
||||||
|
it with the complete corresponding machine-readable source code, which
|
||||||
|
must be distributed under the terms of Sections 1 and 2 above on a
|
||||||
|
medium customarily used for software interchange.
|
||||||
|
|
||||||
|
If distribution of object code is made by offering access to copy
|
||||||
|
from a designated place, then offering equivalent access to copy the
|
||||||
|
source code from the same place satisfies the requirement to
|
||||||
|
distribute the source code, even though third parties are not
|
||||||
|
compelled to copy the source along with the object code.
|
||||||
|
|
||||||
|
5. A program that contains no derivative of any portion of the
|
||||||
|
Library, but is designed to work with the Library by being compiled or
|
||||||
|
linked with it, is called a "work that uses the Library". Such a
|
||||||
|
work, in isolation, is not a derivative work of the Library, and
|
||||||
|
therefore falls outside the scope of this License.
|
||||||
|
|
||||||
|
However, linking a "work that uses the Library" with the Library
|
||||||
|
creates an executable that is a derivative of the Library (because it
|
||||||
|
contains portions of the Library), rather than a "work that uses the
|
||||||
|
library". The executable is therefore covered by this License.
|
||||||
|
Section 6 states terms for distribution of such executables.
|
||||||
|
|
||||||
|
When a "work that uses the Library" uses material from a header file
|
||||||
|
that is part of the Library, the object code for the work may be a
|
||||||
|
derivative work of the Library even though the source code is not.
|
||||||
|
Whether this is true is especially significant if the work can be
|
||||||
|
linked without the Library, or if the work is itself a library. The
|
||||||
|
threshold for this to be true is not precisely defined by law.
|
||||||
|
|
||||||
|
If such an object file uses only numerical parameters, data
|
||||||
|
structure layouts and accessors, and small macros and small inline
|
||||||
|
functions (ten lines or less in length), then the use of the object
|
||||||
|
file is unrestricted, regardless of whether it is legally a derivative
|
||||||
|
work. (Executables containing this object code plus portions of the
|
||||||
|
Library will still fall under Section 6.)
|
||||||
|
|
||||||
|
Otherwise, if the work is a derivative of the Library, you may
|
||||||
|
distribute the object code for the work under the terms of Section 6.
|
||||||
|
Any executables containing that work also fall under Section 6,
|
||||||
|
whether or not they are linked directly with the Library itself.
|
||||||
|
|
||||||
|
6. As an exception to the Sections above, you may also combine or
|
||||||
|
link a "work that uses the Library" with the Library to produce a
|
||||||
|
work containing portions of the Library, and distribute that work
|
||||||
|
under terms of your choice, provided that the terms permit
|
||||||
|
modification of the work for the customer's own use and reverse
|
||||||
|
engineering for debugging such modifications.
|
||||||
|
|
||||||
|
You must give prominent notice with each copy of the work that the
|
||||||
|
Library is used in it and that the Library and its use are covered by
|
||||||
|
this License. You must supply a copy of this License. If the work
|
||||||
|
during execution displays copyright notices, you must include the
|
||||||
|
copyright notice for the Library among them, as well as a reference
|
||||||
|
directing the user to the copy of this License. Also, you must do one
|
||||||
|
of these things:
|
||||||
|
|
||||||
|
a) Accompany the work with the complete corresponding
|
||||||
|
machine-readable source code for the Library including whatever
|
||||||
|
changes were used in the work (which must be distributed under
|
||||||
|
Sections 1 and 2 above); and, if the work is an executable linked
|
||||||
|
with the Library, with the complete machine-readable "work that
|
||||||
|
uses the Library", as object code and/or source code, so that the
|
||||||
|
user can modify the Library and then relink to produce a modified
|
||||||
|
executable containing the modified Library. (It is understood
|
||||||
|
that the user who changes the contents of definitions files in the
|
||||||
|
Library will not necessarily be able to recompile the application
|
||||||
|
to use the modified definitions.)
|
||||||
|
|
||||||
|
b) Use a suitable shared library mechanism for linking with the
|
||||||
|
Library. A suitable mechanism is one that (1) uses at run time a
|
||||||
|
copy of the library already present on the user's computer system,
|
||||||
|
rather than copying library functions into the executable, and (2)
|
||||||
|
will operate properly with a modified version of the library, if
|
||||||
|
the user installs one, as long as the modified version is
|
||||||
|
interface-compatible with the version that the work was made with.
|
||||||
|
|
||||||
|
c) Accompany the work with a written offer, valid for at
|
||||||
|
least three years, to give the same user the materials
|
||||||
|
specified in Subsection 6a, above, for a charge no more
|
||||||
|
than the cost of performing this distribution.
|
||||||
|
|
||||||
|
d) If distribution of the work is made by offering access to copy
|
||||||
|
from a designated place, offer equivalent access to copy the above
|
||||||
|
specified materials from the same place.
|
||||||
|
|
||||||
|
e) Verify that the user has already received a copy of these
|
||||||
|
materials or that you have already sent this user a copy.
|
||||||
|
|
||||||
|
For an executable, the required form of the "work that uses the
|
||||||
|
Library" must include any data and utility programs needed for
|
||||||
|
reproducing the executable from it. However, as a special exception,
|
||||||
|
the materials to be distributed need not include anything that is
|
||||||
|
normally distributed (in either source or binary form) with the major
|
||||||
|
components (compiler, kernel, and so on) of the operating system on
|
||||||
|
which the executable runs, unless that component itself accompanies
|
||||||
|
the executable.
|
||||||
|
|
||||||
|
It may happen that this requirement contradicts the license
|
||||||
|
restrictions of other proprietary libraries that do not normally
|
||||||
|
accompany the operating system. Such a contradiction means you cannot
|
||||||
|
use both them and the Library together in an executable that you
|
||||||
|
distribute.
|
||||||
|
|
||||||
|
7. You may place library facilities that are a work based on the
|
||||||
|
Library side-by-side in a single library together with other library
|
||||||
|
facilities not covered by this License, and distribute such a combined
|
||||||
|
library, provided that the separate distribution of the work based on
|
||||||
|
the Library and of the other library facilities is otherwise
|
||||||
|
permitted, and provided that you do these two things:
|
||||||
|
|
||||||
|
a) Accompany the combined library with a copy of the same work
|
||||||
|
based on the Library, uncombined with any other library
|
||||||
|
facilities. This must be distributed under the terms of the
|
||||||
|
Sections above.
|
||||||
|
|
||||||
|
b) Give prominent notice with the combined library of the fact
|
||||||
|
that part of it is a work based on the Library, and explaining
|
||||||
|
where to find the accompanying uncombined form of the same work.
|
||||||
|
|
||||||
|
8. You may not copy, modify, sublicense, link with, or distribute
|
||||||
|
the Library except as expressly provided under this License. Any
|
||||||
|
attempt otherwise to copy, modify, sublicense, link with, or
|
||||||
|
distribute the Library is void, and will automatically terminate your
|
||||||
|
rights under this License. However, parties who have received copies,
|
||||||
|
or rights, from you under this License will not have their licenses
|
||||||
|
terminated so long as such parties remain in full compliance.
|
||||||
|
|
||||||
|
9. You are not required to accept this License, since you have not
|
||||||
|
signed it. However, nothing else grants you permission to modify or
|
||||||
|
distribute the Library or its derivative works. These actions are
|
||||||
|
prohibited by law if you do not accept this License. Therefore, by
|
||||||
|
modifying or distributing the Library (or any work based on the
|
||||||
|
Library), you indicate your acceptance of this License to do so, and
|
||||||
|
all its terms and conditions for copying, distributing or modifying
|
||||||
|
the Library or works based on it.
|
||||||
|
|
||||||
|
10. Each time you redistribute the Library (or any work based on the
|
||||||
|
Library), the recipient automatically receives a license from the
|
||||||
|
original licensor to copy, distribute, link with or modify the Library
|
||||||
|
subject to these terms and conditions. You may not impose any further
|
||||||
|
restrictions on the recipients' exercise of the rights granted herein.
|
||||||
|
You are not responsible for enforcing compliance by third parties with
|
||||||
|
this License.
|
||||||
|
|
||||||
|
11. If, as a consequence of a court judgment or allegation of patent
|
||||||
|
infringement or for any other reason (not limited to patent issues),
|
||||||
|
conditions are imposed on you (whether by court order, agreement or
|
||||||
|
otherwise) that contradict the conditions of this License, they do not
|
||||||
|
excuse you from the conditions of this License. If you cannot
|
||||||
|
distribute so as to satisfy simultaneously your obligations under this
|
||||||
|
License and any other pertinent obligations, then as a consequence you
|
||||||
|
may not distribute the Library at all. For example, if a patent
|
||||||
|
license would not permit royalty-free redistribution of the Library by
|
||||||
|
all those who receive copies directly or indirectly through you, then
|
||||||
|
the only way you could satisfy both it and this License would be to
|
||||||
|
refrain entirely from distribution of the Library.
|
||||||
|
|
||||||
|
If any portion of this section is held invalid or unenforceable under any
|
||||||
|
particular circumstance, the balance of the section is intended to apply,
|
||||||
|
and the section as a whole is intended to apply in other circumstances.
|
||||||
|
|
||||||
|
It is not the purpose of this section to induce you to infringe any
|
||||||
|
patents or other property right claims or to contest validity of any
|
||||||
|
such claims; this section has the sole purpose of protecting the
|
||||||
|
integrity of the free software distribution system which is
|
||||||
|
implemented by public license practices. Many people have made
|
||||||
|
generous contributions to the wide range of software distributed
|
||||||
|
through that system in reliance on consistent application of that
|
||||||
|
system; it is up to the author/donor to decide if he or she is willing
|
||||||
|
to distribute software through any other system and a licensee cannot
|
||||||
|
impose that choice.
|
||||||
|
|
||||||
|
This section is intended to make thoroughly clear what is believed to
|
||||||
|
be a consequence of the rest of this License.
|
||||||
|
|
||||||
|
12. If the distribution and/or use of the Library is restricted in
|
||||||
|
certain countries either by patents or by copyrighted interfaces, the
|
||||||
|
original copyright holder who places the Library under this License may add
|
||||||
|
an explicit geographical distribution limitation excluding those countries,
|
||||||
|
so that distribution is permitted only in or among countries not thus
|
||||||
|
excluded. In such case, this License incorporates the limitation as if
|
||||||
|
written in the body of this License.
|
||||||
|
|
||||||
|
13. The Free Software Foundation may publish revised and/or new
|
||||||
|
versions of the Lesser General Public License from time to time.
|
||||||
|
Such new versions will be similar in spirit to the present version,
|
||||||
|
but may differ in detail to address new problems or concerns.
|
||||||
|
|
||||||
|
Each version is given a distinguishing version number. If the Library
|
||||||
|
specifies a version number of this License which applies to it and
|
||||||
|
"any later version", you have the option of following the terms and
|
||||||
|
conditions either of that version or of any later version published by
|
||||||
|
the Free Software Foundation. If the Library does not specify a
|
||||||
|
license version number, you may choose any version ever published by
|
||||||
|
the Free Software Foundation.
|
||||||
|
|
||||||
|
14. If you wish to incorporate parts of the Library into other free
|
||||||
|
programs whose distribution conditions are incompatible with these,
|
||||||
|
write to the author to ask for permission. For software which is
|
||||||
|
copyrighted by the Free Software Foundation, write to the Free
|
||||||
|
Software Foundation; we sometimes make exceptions for this. Our
|
||||||
|
decision will be guided by the two goals of preserving the free status
|
||||||
|
of all derivatives of our free software and of promoting the sharing
|
||||||
|
and reuse of software generally.
|
||||||
|
|
||||||
|
NO WARRANTY
|
||||||
|
|
||||||
|
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
|
||||||
|
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
|
||||||
|
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
|
||||||
|
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
|
||||||
|
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
|
||||||
|
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
||||||
|
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
|
||||||
|
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
|
||||||
|
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
||||||
|
|
||||||
|
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
|
||||||
|
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
|
||||||
|
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
|
||||||
|
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
|
||||||
|
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
|
||||||
|
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
|
||||||
|
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
|
||||||
|
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
|
||||||
|
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
|
||||||
|
DAMAGES.
|
||||||

|
||||||

END OF TERMS AND CONDITIONS

How to Apply These Terms to Your New Libraries
|
||||||
|
|
||||||
|
If you develop a new library, and you want it to be of the greatest
|
||||||
|
possible use to the public, we recommend making it free software that
|
||||||
|
everyone can redistribute and change. You can do so by permitting
|
||||||
|
redistribution under these terms (or, alternatively, under the terms of the
|
||||||
|
ordinary General Public License).
|
||||||
|
|
||||||
|
To apply these terms, attach the following notices to the library. It is
|
||||||
|
safest to attach them to the start of each source file to most effectively
|
||||||
|
convey the exclusion of warranty; and each file should have at least the
|
||||||
|
"copyright" line and a pointer to where the full notice is found.
|
||||||
|
|
||||||
|
<one line to give the library's name and a brief idea of what it does.>
|
||||||
|
Copyright (C) <year> <name of author>
|
||||||
|
|
||||||
|
This library is free software; you can redistribute it and/or
|
||||||
|
modify it under the terms of the GNU Lesser General Public
|
||||||
|
License as published by the Free Software Foundation; either
|
||||||
|
version 2.1 of the License, or (at your option) any later version.
|
||||||
|
|
||||||
|
This library is distributed in the hope that it will be useful,
|
||||||
|
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
||||||
|
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
|
||||||
|
Lesser General Public License for more details.
|
||||||
|
|
||||||
|
You should have received a copy of the GNU Lesser General Public
|
||||||
|
License along with this library; if not, write to the Free Software
|
||||||
|

|
||||||
|
|
||||||
|
Also add information on how to contact you by electronic and paper mail.
|
||||||
|
|
||||||
|
You should also get your employer (if you work as a programmer) or your
|
||||||
|
school, if any, to sign a "copyright disclaimer" for the library, if
|
||||||
|
necessary. Here is a sample; alter the names:
|
||||||
|
|
||||||
|
Yoyodyne, Inc., hereby disclaims all copyright interest in the
|

GNU LESSER GENERAL PUBLIC LICENSE

Version 2.1, February 1999
|
|
||||||
|
|
||||||
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
|
|
||||||
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
|
|
||||||
Everyone is permitted to copy and distribute verbatim copies
|
|
||||||
of this license document, but changing it is not allowed.
|
|
||||||
|
|
||||||
[This is the first released version of the Lesser GPL. It also counts
|
|
||||||
as the successor of the GNU Library Public License, version 2, hence
|
|
||||||
the version number 2.1.]
|
|
||||||
|
|
||||||
Preamble
|
|
||||||
|
|
||||||
The licenses for most software are designed to take away your
|
|
||||||
freedom to share and change it. By contrast, the GNU General Public
|
|
||||||
Licenses are intended to guarantee your freedom to share and change
|
|
||||||
free software--to make sure the software is free for all its users.
|
|
||||||
|
|
||||||
This license, the Lesser General Public License, applies to some
|
|
||||||
specially designated software packages--typically libraries--of the
|
|
||||||
Free Software Foundation and other authors who decide to use it. You
|
|
||||||
can use it too, but we suggest you first think carefully about whether
|
|
||||||
this license or the ordinary General Public License is the better
|
|
||||||
strategy to use in any particular case, based on the explanations below.
|
|
||||||
|
|
||||||
When we speak of free software, we are referring to freedom of use,
|
|
||||||
not price. Our General Public Licenses are designed to make sure that
|
|
||||||
you have the freedom to distribute copies of free software (and charge
|
|
||||||
for this service if you wish); that you receive source code or can get
|
|
||||||
it if you want it; that you can change the software and use pieces of
|
|
||||||
it in new free programs; and that you are informed that you can do
|
|
||||||
these things.
|
|
||||||
|
|
||||||
To protect your rights, we need to make restrictions that forbid
|
|
||||||
distributors to deny you these rights or to ask you to surrender these
|
|
||||||
rights. These restrictions translate to certain responsibilities for
|
|
||||||
you if you distribute copies of the library or if you modify it.
|
|
||||||
|
|
||||||
For example, if you distribute copies of the library, whether gratis
|
|
||||||
or for a fee, you must give the recipients all the rights that we gave
|
|
||||||
you. You must make sure that they, too, receive or can get the source
|
|
||||||
code. If you link other code with the library, you must provide
|
|
||||||
complete object files to the recipients, so that they can relink them
|
|
||||||
with the library after making changes to the library and recompiling
|
|
||||||
it. And you must show them these terms so they know their rights.
|
|
||||||
|
|
||||||
We protect your rights with a two-step method: (1) we copyright the
|
|
||||||
library, and (2) we offer you this license, which gives you legal
|
|
||||||
permission to copy, distribute and/or modify the library.
|
|
||||||
|
|
||||||
To protect each distributor, we want to make it very clear that
|
|
||||||
there is no warranty for the free library. Also, if the library is
|
|
||||||
modified by someone else and passed on, the recipients should know
|
|
||||||
that what they have is not the original version, so that the original
|
|
||||||
author's reputation will not be affected by problems that might be
|
|
||||||
introduced by others.
|
|
||||||
|
|
||||||
Finally, software patents pose a constant threat to the existence of
|
|
||||||
any free program. We wish to make sure that a company cannot
|
|
||||||
effectively restrict the users of a free program by obtaining a
|
|
||||||
restrictive license from a patent holder. Therefore, we insist that
|
|
||||||
any patent license obtained for a version of the library must be
|
|
||||||
consistent with the full freedom of use specified in this license.
|
|
||||||
|
|
||||||
Most GNU software, including some libraries, is covered by the
|
|
||||||
ordinary GNU General Public License. This license, the GNU Lesser
|
|
||||||
General Public License, applies to certain designated libraries, and
|
|
||||||
is quite different from the ordinary General Public License. We use
|
|
||||||
this license for certain libraries in order to permit linking those
|
|
||||||
libraries into non-free programs.
|
|
||||||
|
|
||||||
When a program is linked with a library, whether statically or using
|
|
||||||
a shared library, the combination of the two is legally speaking a
|
|
||||||
combined work, a derivative of the original library. The ordinary
|
|
||||||
General Public License therefore permits such linking only if the
|
|
||||||
entire combination fits its criteria of freedom. The Lesser General
|
|
||||||
Public License permits more lax criteria for linking other code with
|
|
||||||
the library.
|
|
||||||
|
|
||||||
We call this license the "Lesser" General Public License because it
|
|
||||||
does Less to protect the user's freedom than the ordinary General
|
|
||||||
Public License. It also provides other free software developers Less
|
|
||||||
of an advantage over competing non-free programs. These disadvantages
|
|
||||||
are the reason we use the ordinary General Public License for many
|
|
||||||
libraries. However, the Lesser license provides advantages in certain
|
|
||||||
special circumstances.
|
|
||||||
|
|
||||||
For example, on rare occasions, there may be a special need to
|
|
||||||
encourage the widest possible use of a certain library, so that it becomes
|
|
||||||
a de-facto standard. To achieve this, non-free programs must be
|
|
||||||
allowed to use the library. A more frequent case is that a free
|
|
||||||
library does the same job as widely used non-free libraries. In this
|
|
||||||
case, there is little to gain by limiting the free library to free
|
|
||||||
software only, so we use the Lesser General Public License.
|
|
||||||
|
|
||||||
In other cases, permission to use a particular library in non-free
|
|
||||||
programs enables a greater number of people to use a large body of
|
|
||||||
free software. For example, permission to use the GNU C Library in
|
|
||||||
non-free programs enables many more people to use the whole GNU
|
|
||||||
operating system, as well as its variant, the GNU/Linux operating
|
|
||||||
system.
|
|
||||||
|
|
||||||
Although the Lesser General Public License is Less protective of the
|
|
||||||
users' freedom, it does ensure that the user of a program that is
|
|
||||||
linked with the Library has the freedom and the wherewithal to run
|
|
||||||
that program using a modified version of the Library.
|
|
||||||
|
|
||||||
The precise terms and conditions for copying, distribution and
|
|
||||||
modification follow. Pay close attention to the difference between a
|
|
||||||
"work based on the library" and a "work that uses the library". The
|
|
||||||
former contains code derived from the library, whereas the latter must
|
|
||||||
be combined with the library in order to run.
|
|
||||||
|
|
||||||
GNU LESSER GENERAL PUBLIC LICENSE
|
|
||||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
|
||||||
|
|
||||||
0. This License Agreement applies to any software library or other
|
|
||||||
program which contains a notice placed by the copyright holder or
|
|
||||||
other authorized party saying it may be distributed under the terms of
|
|
||||||
this Lesser General Public License (also called "this License").
|
|
||||||
Each licensee is addressed as "you".
|
|
||||||
|
|
||||||
A "library" means a collection of software functions and/or data
|
|
||||||
prepared so as to be conveniently linked with application programs
|
|
||||||
(which use some of those functions and data) to form executables.
|
|
||||||
|
|
||||||
The "Library", below, refers to any such software library or work
|
|
||||||
which has been distributed under these terms. A "work based on the
|
|
||||||
Library" means either the Library or any derivative work under
|
|
||||||
copyright law: that is to say, a work containing the Library or a
|
|
||||||
portion of it, either verbatim or with modifications and/or translated
|
|
||||||
straightforwardly into another language. (Hereinafter, translation is
|
|
||||||
included without limitation in the term "modification".)
|
|
||||||
|
|
||||||
"Source code" for a work means the preferred form of the work for
|
|
||||||
making modifications to it. For a library, complete source code means
|
|
||||||
all the source code for all modules it contains, plus any associated
|
|
||||||
interface definition files, plus the scripts used to control compilation
|
|
||||||
and installation of the library.
|
|
||||||
|
|
||||||
Activities other than copying, distribution and modification are not
|
|
||||||
covered by this License; they are outside its scope. The act of
|
|
||||||
running a program using the Library is not restricted, and output from
|
|
||||||
such a program is covered only if its contents constitute a work based
|
|
||||||
on the Library (independent of the use of the Library in a tool for
|
|
||||||
writing it). Whether that is true depends on what the Library does
|
|
||||||
and what the program that uses the Library does.
|
|
||||||
|
|
||||||
1. You may copy and distribute verbatim copies of the Library's
|
|
||||||
complete source code as you receive it, in any medium, provided that
|
|
||||||
you conspicuously and appropriately publish on each copy an
|
|
||||||
appropriate copyright notice and disclaimer of warranty; keep intact
|
|
||||||
all the notices that refer to this License and to the absence of any
|
|
||||||
warranty; and distribute a copy of this License along with the
|
|
||||||
Library.
|
|
||||||
|
|
||||||
You may charge a fee for the physical act of transferring a copy,
|
|
||||||
and you may at your option offer warranty protection in exchange for a
|
|
||||||
fee.
|
|
||||||
|
|
||||||
2. You may modify your copy or copies of the Library or any portion
|
|
||||||
of it, thus forming a work based on the Library, and copy and
|
|
||||||
distribute such modifications or work under the terms of Section 1
|
|
||||||
above, provided that you also meet all of these conditions:
|
|
||||||
|
|
||||||
a) The modified work must itself be a software library.
|
|
||||||
|
|
||||||
b) You must cause the files modified to carry prominent notices
|
|
||||||
stating that you changed the files and the date of any change.
|
|
||||||
|
|
||||||
c) You must cause the whole of the work to be licensed at no
|
|
||||||
charge to all third parties under the terms of this License.
|
|
||||||
|
|
||||||
d) If a facility in the modified Library refers to a function or a
|
|
||||||
table of data to be supplied by an application program that uses
|
|
||||||
the facility, other than as an argument passed when the facility
|
|
||||||
is invoked, then you must make a good faith effort to ensure that,
|
|
||||||
in the event an application does not supply such function or
|
|
||||||
table, the facility still operates, and performs whatever part of
|
|
||||||
its purpose remains meaningful.
|
|
||||||
|
|
||||||
(For example, a function in a library to compute square roots has
|
|
||||||
a purpose that is entirely well-defined independent of the
|
|
||||||
application. Therefore, Subsection 2d requires that any
|
|
||||||
application-supplied function or table used by this function must
|
|
||||||
be optional: if the application does not supply it, the square
|
|
||||||
root function must still compute square roots.)
|
|
||||||
|
|
||||||
These requirements apply to the modified work as a whole. If
|
|
||||||
identifiable sections of that work are not derived from the Library,
|
|
||||||
and can be reasonably considered independent and separate works in
|
|
||||||
themselves, then this License, and its terms, do not apply to those
|
|
||||||
sections when you distribute them as separate works. But when you
|
|
||||||
distribute the same sections as part of a whole which is a work based
|
|
||||||
on the Library, the distribution of the whole must be on the terms of
|
|
||||||
this License, whose permissions for other licensees extend to the
|
|
||||||
entire whole, and thus to each and every part regardless of who wrote
|
|
||||||
it.
|
|
||||||
|
|
||||||
Thus, it is not the intent of this section to claim rights or contest
|
|
||||||
your rights to work written entirely by you; rather, the intent is to
|
|
||||||
exercise the right to control the distribution of derivative or
|
|
||||||
collective works based on the Library.
|
|
||||||
|
|
||||||
In addition, mere aggregation of another work not based on the Library
|
|
||||||
with the Library (or with a work based on the Library) on a volume of
|
|
||||||
a storage or distribution medium does not bring the other work under
|
|
||||||
the scope of this License.
|
|
||||||
|
|
||||||
3. You may opt to apply the terms of the ordinary GNU General Public
|
|
||||||
License instead of this License to a given copy of the Library. To do
|
|
||||||
this, you must alter all the notices that refer to this License, so
|
|
||||||
that they refer to the ordinary GNU General Public License, version 2,
|
|
||||||
instead of to this License. (If a newer version than version 2 of the
|
|
||||||
ordinary GNU General Public License has appeared, then you can specify
|
|
||||||
that version instead if you wish.) Do not make any other change in
|
|
||||||
these notices.
|
|
||||||
|
|
||||||
Once this change is made in a given copy, it is irreversible for
|
|
||||||
that copy, so the ordinary GNU General Public License applies to all
|
|
||||||
subsequent copies and derivative works made from that copy.
|
|
||||||
|
|
||||||
This option is useful when you wish to copy part of the code of
|
|
||||||
the Library into a program that is not a library.
|
|
||||||
|
|
||||||
4. You may copy and distribute the Library (or a portion or
|
|
||||||
derivative of it, under Section 2) in object code or executable form
|
|
||||||
under the terms of Sections 1 and 2 above provided that you accompany
|
|
||||||
it with the complete corresponding machine-readable source code, which
|
|
||||||
must be distributed under the terms of Sections 1 and 2 above on a
|
|
||||||
medium customarily used for software interchange.
|
|
||||||
|
|
||||||
If distribution of object code is made by offering access to copy
|
|
||||||
from a designated place, then offering equivalent access to copy the
|
|
||||||
source code from the same place satisfies the requirement to
|
|
||||||
distribute the source code, even though third parties are not
|
|
||||||
compelled to copy the source along with the object code.
|
|
||||||
|
|
||||||
5. A program that contains no derivative of any portion of the
|
|
||||||
Library, but is designed to work with the Library by being compiled or
|
|
||||||
linked with it, is called a "work that uses the Library". Such a
|
|
||||||
work, in isolation, is not a derivative work of the Library, and
|
|
||||||
therefore falls outside the scope of this License.
|
|
||||||
|
|
||||||
However, linking a "work that uses the Library" with the Library
|
|
||||||
creates an executable that is a derivative of the Library (because it
|
|
||||||
contains portions of the Library), rather than a "work that uses the
|
|
||||||
library". The executable is therefore covered by this License.
|
|
||||||
Section 6 states terms for distribution of such executables.
|
|
||||||
|
|
||||||
When a "work that uses the Library" uses material from a header file
|
|
||||||
that is part of the Library, the object code for the work may be a
|
|
||||||
derivative work of the Library even though the source code is not.
|
|
||||||
Whether this is true is especially significant if the work can be
|
|
||||||
linked without the Library, or if the work is itself a library. The
|
|
||||||
threshold for this to be true is not precisely defined by law.
|
|
||||||
|
|
||||||
If such an object file uses only numerical parameters, data
|
|
||||||
structure layouts and accessors, and small macros and small inline
|
|
||||||
functions (ten lines or less in length), then the use of the object
|
|
||||||
file is unrestricted, regardless of whether it is legally a derivative
|
|
||||||
work. (Executables containing this object code plus portions of the
|
|
||||||
Library will still fall under Section 6.)
|
|
||||||
|
|
||||||
Otherwise, if the work is a derivative of the Library, you may
|
|
||||||
distribute the object code for the work under the terms of Section 6.
|
|
||||||
Any executables containing that work also fall under Section 6,
|
|
||||||
whether or not they are linked directly with the Library itself.
|
|
||||||
|
|
||||||
6. As an exception to the Sections above, you may also combine or
|
|
||||||
link a "work that uses the Library" with the Library to produce a
|
|
||||||
work containing portions of the Library, and distribute that work
|
|
||||||
under terms of your choice, provided that the terms permit
|
|
||||||
modification of the work for the customer's own use and reverse
|
|
||||||
engineering for debugging such modifications.
|
|
||||||
|
|
||||||
You must give prominent notice with each copy of the work that the
|
|
||||||
Library is used in it and that the Library and its use are covered by
|
|
||||||
this License. You must supply a copy of this License. If the work
|
|
||||||
during execution displays copyright notices, you must include the
|
|
||||||
copyright notice for the Library among them, as well as a reference
|
|
||||||
directing the user to the copy of this License. Also, you must do one
|
|
||||||
of these things:
|
|
||||||
|
|
||||||
a) Accompany the work with the complete corresponding
|
|
||||||
machine-readable source code for the Library including whatever
|
|
||||||
changes were used in the work (which must be distributed under
|
|
||||||
Sections 1 and 2 above); and, if the work is an executable linked
|
|
||||||
with the Library, with the complete machine-readable "work that
|
|
||||||
uses the Library", as object code and/or source code, so that the
|
|
||||||
user can modify the Library and then relink to produce a modified
|
|
||||||
executable containing the modified Library. (It is understood
|
|
||||||
that the user who changes the contents of definitions files in the
|
|
||||||
Library will not necessarily be able to recompile the application
|
|
||||||
to use the modified definitions.)
|
|
||||||
|
|
||||||
b) Use a suitable shared library mechanism for linking with the
|
|
||||||
Library. A suitable mechanism is one that (1) uses at run time a
|
|
||||||
copy of the library already present on the user's computer system,
|
|
||||||
rather than copying library functions into the executable, and (2)
|
|
||||||
will operate properly with a modified version of the library, if
|
|
||||||
the user installs one, as long as the modified version is
|
|
||||||
interface-compatible with the version that the work was made with.
|
|
||||||
|
|
||||||
c) Accompany the work with a written offer, valid for at
|
|
||||||
least three years, to give the same user the materials
|
|
||||||
specified in Subsection 6a, above, for a charge no more
|
|
||||||
than the cost of performing this distribution.
|
|
||||||
|
|
||||||
d) If distribution of the work is made by offering access to copy
|
|
||||||
from a designated place, offer equivalent access to copy the above
|
|
||||||
specified materials from the same place.
|
|
||||||
|
|
||||||
e) Verify that the user has already received a copy of these
|
|
||||||
materials or that you have already sent this user a copy.
|
|
||||||
|
|
||||||
For an executable, the required form of the "work that uses the
|
|
||||||
Library" must include any data and utility programs needed for
|
|
||||||
reproducing the executable from it. However, as a special exception,
|
|
||||||
the materials to be distributed need not include anything that is
|
|
||||||
normally distributed (in either source or binary form) with the major
|
|
||||||
components (compiler, kernel, and so on) of the operating system on
|
|
||||||
which the executable runs, unless that component itself accompanies
|
|
||||||
the executable.
|
|
||||||
|
|
||||||
It may happen that this requirement contradicts the license
|
|
||||||
restrictions of other proprietary libraries that do not normally
|
|
||||||
accompany the operating system. Such a contradiction means you cannot
|
|
||||||
use both them and the Library together in an executable that you
|
|
||||||
distribute.
|
|
||||||
|
|
||||||
7. You may place library facilities that are a work based on the
|
|
||||||
Library side-by-side in a single library together with other library
|
|
||||||
facilities not covered by this License, and distribute such a combined
|
|
||||||
library, provided that the separate distribution of the work based on
|
|
||||||
the Library and of the other library facilities is otherwise
|
|
||||||
permitted, and provided that you do these two things:
|
|
||||||
|
|
||||||
a) Accompany the combined library with a copy of the same work
|
|
||||||
based on the Library, uncombined with any other library
|
|
||||||
facilities. This must be distributed under the terms of the
|
|
||||||
Sections above.
|
|
||||||
|
|
||||||
b) Give prominent notice with the combined library of the fact
|
|
||||||
that part of it is a work based on the Library, and explaining
|
|
||||||
where to find the accompanying uncombined form of the same work.
|
|
||||||
|
|
||||||
8. You may not copy, modify, sublicense, link with, or distribute
|
|
||||||
the Library except as expressly provided under this License. Any
|
|
||||||
attempt otherwise to copy, modify, sublicense, link with, or
|
|
||||||
distribute the Library is void, and will automatically terminate your
|
|
||||||
rights under this License. However, parties who have received copies,
|
|
||||||
or rights, from you under this License will not have their licenses
|
|
||||||
terminated so long as such parties remain in full compliance.
|
|
||||||
|
|
||||||
9. You are not required to accept this License, since you have not
|
|
||||||
signed it. However, nothing else grants you permission to modify or
|
|
||||||
distribute the Library or its derivative works. These actions are
|
|
||||||
prohibited by law if you do not accept this License. Therefore, by
|
|
||||||
modifying or distributing the Library (or any work based on the
|
|
||||||
Library), you indicate your acceptance of this License to do so, and
|
|
||||||
all its terms and conditions for copying, distributing or modifying
|
|
||||||
the Library or works based on it.
|
|
||||||
|
|
||||||
10. Each time you redistribute the Library (or any work based on the
|
|
||||||
Library), the recipient automatically receives a license from the
|
|
||||||
original licensor to copy, distribute, link with or modify the Library
|
|
||||||
subject to these terms and conditions. You may not impose any further
|
|
||||||
restrictions on the recipients' exercise of the rights granted herein.
|
|
||||||
You are not responsible for enforcing compliance by third parties with
|
|
||||||
this License.
|
|
||||||
|
|
||||||
11. If, as a consequence of a court judgment or allegation of patent
|
|
||||||
infringement or for any other reason (not limited to patent issues),
|
|
||||||
conditions are imposed on you (whether by court order, agreement or
|
|
||||||
otherwise) that contradict the conditions of this License, they do not
|
|
||||||
excuse you from the conditions of this License. If you cannot
|
|
||||||
distribute so as to satisfy simultaneously your obligations under this
|
|
||||||
License and any other pertinent obligations, then as a consequence you
|
|
||||||
may not distribute the Library at all. For example, if a patent
|
|
||||||
license would not permit royalty-free redistribution of the Library by
|
|
||||||
all those who receive copies directly or indirectly through you, then
|
|
||||||
the only way you could satisfy both it and this License would be to
|
|
||||||
refrain entirely from distribution of the Library.
|
|
||||||
|
|
||||||
If any portion of this section is held invalid or unenforceable under any
|
|
||||||
particular circumstance, the balance of the section is intended to apply,
|
|
||||||
and the section as a whole is intended to apply in other circumstances.
|
|
||||||
|
|
||||||
It is not the purpose of this section to induce you to infringe any
|
|
||||||
patents or other property right claims or to contest validity of any
|
|
||||||
such claims; this section has the sole purpose of protecting the
|
|
||||||
integrity of the free software distribution system which is
|
|
||||||
implemented by public license practices. Many people have made
|
|
||||||
generous contributions to the wide range of software distributed
|
|
||||||
through that system in reliance on consistent application of that
|
|
||||||
system; it is up to the author/donor to decide if he or she is willing
|
|
||||||
to distribute software through any other system and a licensee cannot
|
|
||||||
impose that choice.
|
|
||||||
|
|
||||||
This section is intended to make thoroughly clear what is believed to
|
|
||||||
be a consequence of the rest of this License.
|
|
||||||
|
|
||||||
12. If the distribution and/or use of the Library is restricted in
|
|
||||||
certain countries either by patents or by copyrighted interfaces, the
|
|
||||||
original copyright holder who places the Library under this License may add
|
|
||||||
an explicit geographical distribution limitation excluding those countries,
|
|
||||||
so that distribution is permitted only in or among countries not thus
|
|
||||||
excluded. In such case, this License incorporates the limitation as if
|
|
||||||
written in the body of this License.
|
|
||||||
|
|
||||||
13. The Free Software Foundation may publish revised and/or new
|
|
||||||
versions of the Lesser General Public License from time to time.
|
|
||||||
Such new versions will be similar in spirit to the present version,
|
|
||||||
but may differ in detail to address new problems or concerns.
|
|
||||||
|
|
||||||
Each version is given a distinguishing version number. If the Library
|
|
||||||
specifies a version number of this License which applies to it and
|
|
||||||
"any later version", you have the option of following the terms and
|
|
||||||
conditions either of that version or of any later version published by
|
|
||||||
the Free Software Foundation. If the Library does not specify a
|
|
||||||
license version number, you may choose any version ever published by
|
|
||||||
the Free Software Foundation.
|
|
||||||
|
|
||||||
14. If you wish to incorporate parts of the Library into other free
|
|
||||||
programs whose distribution conditions are incompatible with these,
|
|
||||||
write to the author to ask for permission. For software which is
|
|
||||||
copyrighted by the Free Software Foundation, write to the Free
|
|
||||||
Software Foundation; we sometimes make exceptions for this. Our
|
|
||||||
decision will be guided by the two goals of preserving the free status
|
|
||||||
of all derivatives of our free software and of promoting the sharing
|
|
||||||
and reuse of software generally.
|
|
||||||
|
|
||||||
NO WARRANTY
|
|
||||||
|
|
||||||
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
|
|
||||||
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
|
|
||||||
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
|
|
||||||
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
|
|
||||||
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
|
|
||||||
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
|
||||||
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
|
|
||||||
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
|
|
||||||
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
|
||||||
|
|
||||||
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
|
|
||||||
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
|
|
||||||
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
|
|
||||||
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
|
|
||||||
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
|
|
||||||
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
|
|
||||||
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
|
|
||||||
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
|
|
||||||
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
|
|
||||||
DAMAGES.
|
|
||||||
|
|
||||||
END OF TERMS AND CONDITIONS
|
|
||||||
|
|
||||||
How to Apply These Terms to Your New Libraries
|
|
||||||
|
|
||||||
If you develop a new library, and you want it to be of the greatest
|
|
||||||
possible use to the public, we recommend making it free software that
|
|
||||||
everyone can redistribute and change. You can do so by permitting
|
|
||||||
redistribution under these terms (or, alternatively, under the terms of the
|
|
||||||
ordinary General Public License).
|
|
||||||
|
|
||||||
To apply these terms, attach the following notices to the library. It is
|
|
||||||
safest to attach them to the start of each source file to most effectively
|
|
||||||
convey the exclusion of warranty; and each file should have at least the
|
|
||||||
"copyright" line and a pointer to where the full notice is found.
|
|
||||||
|
|
||||||
<one line to give the library's name and a brief idea of what it does.>
|
|
||||||
Copyright (C) <year> <name of author>
|
|
||||||
|
|
||||||
This library is free software; you can redistribute it and/or
|
|
||||||
modify it under the terms of the GNU Lesser General Public
|
|
||||||
License as published by the Free Software Foundation; either
|
|
||||||
version 2.1 of the License, or (at your option) any later version.
|
|
||||||
|
|
||||||
This library is distributed in the hope that it will be useful,
|
|
||||||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
|
||||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
|
|
||||||
Lesser General Public License for more details.
|
|
||||||
|
|
||||||
You should have received a copy of the GNU Lesser General Public
|
|
||||||
License along with this library; if not, write to the Free Software
|
|
||||||
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
|
|
||||||
|
|
||||||
Also add information on how to contact you by electronic and paper mail.
|
|
||||||
|
|
||||||
You should also get your employer (if you work as a programmer) or your
|
|
||||||
school, if any, to sign a "copyright disclaimer" for the library, if
|
|
||||||
necessary. Here is a sample; alter the names:
|
|
||||||
|
|
||||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the
|
|
||||||
library `Frob' (a library for tweaking knobs) written by James Random Hacker.

GNU LESSER GENERAL PUBLIC LICENSE

|
||||||
Version 3, 29 June 2007
|
|
||||||
|
|
||||||
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
|
|
||||||
Everyone is permitted to copy and distribute verbatim copies
|
|
||||||
of this license document, but changing it is not allowed.
|
|
||||||
|
|
||||||
|
|
||||||
This version of the GNU Lesser General Public License incorporates
|
|
||||||
the terms and conditions of version 3 of the GNU General Public
|
|
||||||
License, supplemented by the additional permissions listed below.
|
|
||||||
|
|
||||||
0. Additional Definitions.
|
|
||||||
|
|
||||||
As used herein, "this License" refers to version 3 of the GNU Lesser
|
|
||||||
General Public License, and the "GNU GPL" refers to version 3 of the GNU
|
|
||||||
General Public License.
|
|
||||||
|
|
||||||
"The Library" refers to a covered work governed by this License,
|
|
||||||
other than an Application or a Combined Work as defined below.
|
|
||||||
|
|
||||||
An "Application" is any work that makes use of an interface provided
|
|
||||||
by the Library, but which is not otherwise based on the Library.
|
|
||||||
Defining a subclass of a class defined by the Library is deemed a mode
|
|
||||||
of using an interface provided by the Library.
|
|
||||||
|
|
||||||
A "Combined Work" is a work produced by combining or linking an
|
|
||||||
Application with the Library. The particular version of the Library
|
|
||||||
with which the Combined Work was made is also called the "Linked
|
|
||||||
Version".
|
|
||||||
|
|
||||||
The "Minimal Corresponding Source" for a Combined Work means the
|
|
||||||
Corresponding Source for the Combined Work, excluding any source code
|
|
||||||
for portions of the Combined Work that, considered in isolation, are
|
|
||||||
based on the Application, and not on the Linked Version.
|
|
||||||
|
|
||||||
The "Corresponding Application Code" for a Combined Work means the
|
|
||||||
object code and/or source code for the Application, including any data
|
|
||||||
and utility programs needed for reproducing the Combined Work from the
|
|
||||||
Application, but excluding the System Libraries of the Combined Work.
|
|
||||||
|
|
||||||
1. Exception to Section 3 of the GNU GPL.
|
|
||||||
|
|
||||||
You may convey a covered work under sections 3 and 4 of this License
|
|
||||||
without being bound by section 3 of the GNU GPL.
|
|
||||||
|
|
||||||
2. Conveying Modified Versions.
|
|
||||||
|
|
||||||
If you modify a copy of the Library, and, in your modifications, a
|
|
||||||
facility refers to a function or data to be supplied by an Application
|
|
||||||
that uses the facility (other than as an argument passed when the
|
|
||||||
facility is invoked), then you may convey a copy of the modified
|
|
||||||
version:
|
|
||||||
|
|
||||||
a) under this License, provided that you make a good faith effort to
|
|
||||||
ensure that, in the event an Application does not supply the
|
|
||||||
function or data, the facility still operates, and performs
|
|
||||||
whatever part of its purpose remains meaningful, or
|
|
||||||
|
|
||||||
b) under the GNU GPL, with none of the additional permissions of
|
|
||||||
this License applicable to that copy.
|
|
||||||
|
|
||||||
3. Object Code Incorporating Material from Library Header Files.
|
|
||||||
|
|
||||||
The object code form of an Application may incorporate material from
|
|
||||||
a header file that is part of the Library. You may convey such object
|
|
||||||
code under terms of your choice, provided that, if the incorporated
|
|
||||||
material is not limited to numerical parameters, data structure
|
|
||||||
layouts and accessors, or small macros, inline functions and templates
|
|
||||||
(ten or fewer lines in length), you do both of the following:
|
|
||||||
|
|
||||||
a) Give prominent notice with each copy of the object code that the
|
|
||||||
Library is used in it and that the Library and its use are
|
|
||||||
covered by this License.
|
|
||||||
|
|
||||||
b) Accompany the object code with a copy of the GNU GPL and this license
|
|
||||||
document.
|
|
||||||
|
|
||||||
4. Combined Works.
|
|
||||||
|
|
||||||
You may convey a Combined Work under terms of your choice that,
|
|
||||||
taken together, effectively do not restrict modification of the
|
|
||||||
portions of the Library contained in the Combined Work and reverse
|
|
||||||
engineering for debugging such modifications, if you also do each of
|
|
||||||
the following:
|
|
||||||
|
|
||||||
a) Give prominent notice with each copy of the Combined Work that
|
|
||||||
the Library is used in it and that the Library and its use are
|
|
||||||
covered by this License.
|
|
||||||
|
|
||||||
b) Accompany the Combined Work with a copy of the GNU GPL and this license
|
|
||||||
document.
|
|
||||||
|
|
||||||
c) For a Combined Work that displays copyright notices during
|
|
||||||
execution, include the copyright notice for the Library among
|
|
||||||
these notices, as well as a reference directing the user to the
|
|
||||||
copies of the GNU GPL and this license document.
|
|
||||||
|
|
||||||
d) Do one of the following:
|
|
||||||
|
|
||||||
0) Convey the Minimal Corresponding Source under the terms of this
|
|
||||||
License, and the Corresponding Application Code in a form
|
|
||||||
suitable for, and under terms that permit, the user to
|
|
||||||
recombine or relink the Application with a modified version of
|
|
||||||
the Linked Version to produce a modified Combined Work, in the
|
|
||||||
manner specified by section 6 of the GNU GPL for conveying
|
|
||||||
Corresponding Source.
|
|
||||||
|
|
||||||
1) Use a suitable shared library mechanism for linking with the
|
|
||||||
Library. A suitable mechanism is one that (a) uses at run time
|
|
||||||
a copy of the Library already present on the user's computer
|
|
||||||
system, and (b) will operate properly with a modified version
|
|
||||||
of the Library that is interface-compatible with the Linked
|
|
||||||
Version.
|
|
||||||
|
|
||||||
e) Provide Installation Information, but only if you would otherwise
|
|
||||||
be required to provide such information under section 6 of the
|
|
||||||
GNU GPL, and only to the extent that such information is
|
|
||||||
necessary to install and execute a modified version of the
|
|
||||||
Combined Work produced by recombining or relinking the
|
|
||||||
Application with a modified version of the Linked Version. (If
|
|
||||||
you use option 4d0, the Installation Information must accompany
|
|
||||||
the Minimal Corresponding Source and Corresponding Application
|
|
||||||
Code. If you use option 4d1, you must provide the Installation
|
|
||||||
Information in the manner specified by section 6 of the GNU GPL
|
|
||||||
for conveying Corresponding Source.)
|
|
||||||
|
|
||||||
5. Combined Libraries.
|
|
||||||
|
|
||||||
You may place library facilities that are a work based on the
|

6. Revised Versions of the GNU Lesser General Public License.
|

|

The Free Software Foundation may publish revised and/or new versions

of the GNU Lesser General Public License from time to time. Such new

versions will be similar in spirit to the present version, but may
|

differ in detail to address new problems or concerns.
|
|

|
|

Each version is given a distinguishing version number. If the

Library as you received it specifies that a certain numbered version
|

of the GNU Lesser General Public License "or any later version"
|
|
||||||
applies to it, you have the option of following the terms and
|
|
||||||
conditions either of that published version or of any later version
|
|
||||||
published by the Free Software Foundation. If the Library as you
|
|
||||||
received it does not specify a version number of the GNU Lesser
|
|
||||||
General Public License, you may choose any version of the GNU Lesser
|
|
||||||
General Public License ever published by the Free Software Foundation.
|
|
||||||
|
|
||||||
If the Library as you received it specifies that a proxy can decide
|
|
||||||
whether future versions of the GNU Lesser General Public License shall
|
|
||||||
apply, that proxy's public statement of acceptance of any version is
|
|
||||||
permanent authorization for you to choose that version for the
|
|

Library.

# License
|
|
||||||
|
|
||||||
Most files in FFmpeg are under the GNU Lesser General Public License version 2.1
|
|
||||||
or later (LGPL v2.1+). Read the file `COPYING.LGPLv2.1` for details. Some other
|
|
||||||
files have MIT/X11/BSD-style licenses. In combination the LGPL v2.1+ applies to
|
|
||||||
FFmpeg.
|
|
||||||
|
|
||||||
Some optional parts of FFmpeg are licensed under the GNU General Public License
|
|
||||||
version 2 or later (GPL v2+). See the file `COPYING.GPLv2` for details. None of
|
|
||||||
these parts are used by default, you have to explicitly pass `--enable-gpl` to
|
|
||||||
configure to activate them. In this case, FFmpeg's license changes to GPL v2+.
|
|
||||||
|
|
||||||
Specifically, the GPL parts of FFmpeg are:
|
|
||||||
|
|
||||||
- libpostproc
|
|
||||||
- optional x86 optimization in the files
|
|
||||||
- `libavcodec/x86/flac_dsp_gpl.asm`
|
|
||||||
- `libavcodec/x86/idct_mmx.c`
|

||||||
- `libavfilter/x86/vf_removegrain.asm`
|

||||||
- the following building and testing tools
|

|
|
||||||
- the following filters in libavfilter:
|

- `vf_blackframe.c`
|
|

- `vf_boxblur.c`
|
|
||||||
- `vf_colormatrix.c`

|

|
|
||||||
Should you, for whatever reason, prefer to use version 3 of the (L)GPL, then
|
|
||||||
the configure parameter `--enable-version3` will activate this licensing option
|
|
||||||
for you. Read the file `COPYING.LGPLv3` or, if you have enabled GPL parts,
|
|
||||||
`COPYING.GPLv3` to learn the exact legal terms that apply in this case.
|
|
||||||
|
|
||||||
There are a handful of files under other licensing terms, namely:
|
|
||||||
|
|
||||||
* The files `libavcodec/jfdctfst.c`, `libavcodec/jfdctint_template.c` and
|
|
||||||
`libavcodec/jrevdct.c` are taken from libjpeg, see the top of the files for
|
|
||||||
licensing details. Specifically note that you must credit the IJG in the
|
|
||||||
documentation accompanying your program if you only distribute executables.
|
|
||||||
You must also indicate any changes including additions and deletions to
|
|
||||||
those three files in the documentation.
|
|
||||||
* `tests/reference.pnm` is under the expat license.
|
|
||||||
|
|
||||||
|
|
||||||
## External libraries
|
|
||||||
|
|
||||||
FFmpeg can be combined with a number of external libraries, which sometimes
|
|
||||||
affect the licensing of binaries resulting from the combination.
|
|
||||||
|
|
||||||
### Compatible libraries
|
|
||||||
|
|
||||||
The following libraries are under GPL:
|
|
||||||
- frei0r
|
|
||||||
- libcdio
|
|
||||||
- librubberband
|
|
||||||
- libvidstab
|
|
||||||
- libx264
|
|
||||||
- libx265
|
|
||||||
- libxavs
|
|
||||||
- libxvid
|
|
||||||
|
|
||||||
When combining them with FFmpeg, FFmpeg needs to be licensed as GPL as well by
|
|
||||||
passing `--enable-gpl` to configure.
|
|
||||||
|
|
||||||
The OpenCORE and VisualOn libraries are under the Apache License 2.0. That
|
|
||||||
license is incompatible with the LGPL v2.1 and the GPL v2, but not with
|
|
||||||
version 3 of those licenses. So to combine these libraries with FFmpeg, the
|
|
||||||
license version needs to be upgraded by passing `--enable-version3` to configure.
|
|
||||||
|
|
||||||
### Incompatible libraries
|
|
||||||
|
|
||||||
There are certain libraries you can combine with FFmpeg whose licenses are not
|
|
||||||
compatible with the GPL and/or the LGPL. If you wish to enable these
|
|
||||||
libraries, even in circumstances that their license may be incompatible, pass
|
|
||||||
`--enable-nonfree` to configure. But note that if you enable any of these
|
|
||||||
libraries the resulting binary will be under a complex license mix that is
|
|
||||||
more restrictive than the LGPL and that may result in additional obligations.
|
|
||||||
It is possible that these restrictions cause the resulting binary to be
|
|
||||||
unredistributable.
|
|
||||||
|
|
||||||
The Fraunhofer FDK AAC and OpenSSL libraries are under licenses which are
|
|
||||||
incompatible with the GPLv2 and v3. To the best of our knowledge, they are
|
|
||||||
compatible with the LGPL.
|
|
||||||
|
|
||||||
The NVENC library, while its header file is licensed under the compatible MIT
|
|
||||||
license, requires a proprietary binary blob at run time, and is deemed to be
|
|
||||||
incompatible with the GPL. We are not certain if it is compatible with the
|
|
||||||
LGPL, but we require `--enable-nonfree` even with LGPL configurations in case
|
|
||||||
it is not.

FFmpeg README
|
|
||||||
=============
|
|
||||||
|
|
||||||
FFmpeg is a collection of libraries and tools to process multimedia content
|
|
||||||
such as audio, video, subtitles and related metadata.
|
|
||||||
|
|
||||||
## Libraries
|
|
||||||
|
|
||||||
* `libavcodec` provides implementation of a wider range of codecs.
|
|
||||||
* `libavformat` implements streaming protocols, container formats and basic I/O access.
|
|
||||||
* `libavutil` includes hashers, decompressors and miscellaneous utility functions.
|
|
||||||
* `libavfilter` provides a mean to alter decoded Audio and Video through chain of filters.
|
|
||||||
* `libavdevice` provides an abstraction to access capture and playback devices.
|
|
||||||
* `libswresample` implements audio mixing and resampling routines.
|
|
||||||
* `libswscale` implements color conversion and scaling routines.
|
|
||||||
|
|
||||||
## Tools
|
|
||||||
|
|
||||||
* [ffmpeg](https://ffmpeg.org/ffmpeg.html) is a command line toolbox to
|
|
||||||
manipulate, convert and stream multimedia content.
|
|
||||||
* [ffplay](https://ffmpeg.org/ffplay.html) is a minimalistic multimedia player.
|
|
||||||
* [ffprobe](https://ffmpeg.org/ffprobe.html) is a simple analysis tool to inspect
|
|
||||||
multimedia content.
|
|
||||||
* [ffserver](https://ffmpeg.org/ffserver.html) is a multimedia streaming server
|
|
||||||
for live broadcasts.
|
|
||||||
* Additional small tools such as `aviocat`, `ismindex` and `qt-faststart`.
|
|
||||||

Release Notes

General notes
|
||||||
|
-------------
|
||||||
|
|
||||||
|
It has been so long since the last release that this should be considered the
|
||||||
|
first FFmpeg release of recent times. Because of the way things have unfolded to
|
||||||
|
date, the notes for this version cannot be entirely conventional.
|
||||||
|
|
||||||
|
See the Changelog file for a list of significant changes.
|
||||||
|
|
||||||
|
Please note that our policy on bug reports has not changed. We still only accept
|
||||||
|
bug reports against HEAD of the FFmpeg trunk repository. If you are experiencing
|
||||||
|
any issues with any formally released version of FFmpeg, please try a current
|
||||||
|
version of the development code to check if the issue still exists. If it does,
|
||||||
|
make your report against the development code following the usual bug reporting
|
||||||
|
guidelines.
|
||||||
|
|
||||||
|
API notes
|
||||||
|
---------
|
||||||
|
|
||||||
|
In the next release, it is intended to remove a number of deprecated APIs. We
|
||||||
|
decided to put out a release that includes said APIs for the benefit of third
|
||||||
|
party software.
|
||||||
|
|
||||||
|
As such, this release:
|
||||||
|
- provides a sync point for said APIs
|
||||||
|
- increases awareness of API changes
|
||||||
|
- allows the next release to detail how to transition from the old to the new
|
||||||
|
|
||||||
|
The deprecated APIs to be removed are:
|
||||||
|
- imgconvert (to be replaced by libswscale)
|
||||||
|
- vhook (to be replaced by libavfilter)
|
||||||
|
|
||||||
|
If at all possible, do not use the deprecated APIs. All notes on API changes
|
||||||
|
should appear in doc/APIchanges.

|
||||||
|
* AVFormatContext -> AVInputStream/AVOutputStream
|
||||||
|
* suppress rate_emu from AVCodecContext
|

AVUtil
|
||||||
|
======
|
||||||
|
libavutil is a small lightweight library of generally useful functions.
|
||||||
|
It is not a library for code needed by both libavcodec and libavformat.

||||||
|
|
||||||

aes.c AES encryption and decryption
|
||||||
|
fifo.c resizeable first in first out buffer

intfloat_readwrite.c portable reading and writing of floating point values
|
||||||

log.c "printf" with context and level
|

|
md5.c MD5 Message-Digest Algorithm

|
x86_cpu.h a few useful macros for unifying x86-64 and x86-32 code

common.h
|

Goals:
|
||||||
|
======
|
||||||
|
* Modular (few interdependencies and the possibility of disabling individual parts during ./configure)
|
||||||
|
* Small (source and object)
|
||||||
|
* Efficient (low CPU and memory usage)
|
||||||

@chapter Bitstream Filters
|
|
||||||
@c man begin BITSTREAM FILTERS
|
|
||||||
|
|
||||||
When you configure your FFmpeg build, all the supported bitstream
|
|
||||||
filters are enabled by default. You can list all available ones using
|
|
||||||
the configure option @code{--list-bsfs}.
|
|
||||||
|
|
||||||
You can disable all the bitstream filters using the configure option
|
|
||||||
@code{--disable-bsfs}, and selectively enable any bitstream filter using
|
|
||||||
the option @code{--enable-bsf=BSF}, or you can disable a particular
|
|
||||||
bitstream filter using the option @code{--disable-bsf=BSF}.
|
|
||||||
|
|
||||||
The option @code{-bsfs} of the ff* tools will display the list of
|
|
||||||
all the supported bitstream filters included in your build.
|
|
||||||
|
|
||||||
The ff* tools have a -bsf option applied per stream, taking a
|
|
||||||
comma-separated list of filters, whose parameters follow the filter
|
|
||||||
name after a '='.
|
|
||||||
|
|
||||||
@example
|
|
||||||
ffmpeg -i INPUT -c:v copy -bsf:v filter1[=opt1=str1:opt2=str2][,filter2] OUTPUT
|
|
||||||
@end example
|
|
||||||
|
|
||||||
Below is a description of the currently available bitstream filters,
|
|
||||||
with their parameters, if any.
|
|
||||||
|
|
||||||
@section aac_adtstoasc
|
|
||||||
|
|
||||||
Convert MPEG-2/4 AAC ADTS to an MPEG-4 Audio Specific Configuration
|
|
||||||
bitstream.
|
|
||||||
|
|
||||||
This filter creates an MPEG-4 AudioSpecificConfig from an MPEG-2/4
|
|
||||||
ADTS header and removes the ADTS header.
|
|
||||||
|
|
||||||
This filter is required for example when copying an AAC stream from a
|
|
||||||
raw ADTS AAC or an MPEG-TS container to MP4A-LATM, to an FLV file, or
|
|
||||||
to MOV/MP4 files and related formats such as 3GP or M4A. Please note
|
|
||||||
that it is auto-inserted for MP4A-LATM and MOV/MP4 and related formats.
|
|
||||||
|
|
||||||
@section chomp
|
|
||||||
|
|
||||||
Remove zero padding at the end of a packet.
|
|
||||||
|
|
||||||
@section dca_core
|
|
||||||
|
|
||||||
Extract the core from a DCA/DTS stream, dropping extensions such as
|
|
||||||
DTS-HD.
|
|
||||||
|
|
||||||
@section dump_extra
|
|
||||||
|
|
||||||
Add extradata to the beginning of the filtered packets.
|
|
||||||
|
|
||||||
The additional argument specifies which packets should be filtered.
|
|
||||||
It accepts the values:
|
|
||||||
@table @samp
|
|
||||||
@item a
|
|
||||||
add extradata to all key packets, but only if @var{local_header} is
|
|
||||||
set in the @option{flags2} codec context field
|
|
||||||
|
|
||||||
@item k
|
|
||||||
add extradata to all key packets
|
|
||||||
|
|
||||||
@item e
|
|
||||||
add extradata to all packets
|
|
||||||
@end table
|
|
||||||
|
|
||||||
If not specified it is assumed @samp{k}.
|
|
||||||
|
|
||||||
For example the following @command{ffmpeg} command forces a global
|
|
||||||
header (thus disabling individual packet headers) in the H.264 packets
|
|
||||||
generated by the @code{libx264} encoder, but corrects them by adding
|
|
||||||
the header stored in extradata to the key packets:
|
|
||||||
@example
|
|
||||||
ffmpeg -i INPUT -map 0 -flags:v +global_header -c:v libx264 -bsf:v dump_extra out.ts

@section extract_extradata
|
|
||||||
|
|
||||||
Extract the in-band extradata.
|
|
||||||
|
|
||||||
Certain codecs allow the long-term headers (e.g. MPEG-2 sequence headers,
|
|
||||||
or H.264/HEVC (VPS/)SPS/PPS) to be transmitted either "in-band" (i.e. as a part
|
|
||||||
of the bitstream containing the coded frames) or "out of band" (e.g. on the
|
|
||||||
container level). This latter form is called "extradata" in FFmpeg terminology.
|
|
||||||
|
|
||||||
This bitstream filter detects the in-band headers and makes them available as
|
|
||||||
extradata.
|
|
||||||
|
|
||||||
@table @option
|
|
||||||
@item remove
|
|
||||||
When this option is enabled, the long-term headers are removed from the
|
|
||||||
bitstream after extraction.
|
|
||||||
@end table
|
|
||||||
|
|

@section h264_mp4toannexb
|
|
||||||
|
|
||||||
Convert an H.264 bitstream from length prefixed mode to start code
|
|
||||||
prefixed mode (as defined in the Annex B of the ITU-T H.264
|
|
||||||
specification).
|
|
||||||
|
|
||||||
This is required by some streaming formats, typically the MPEG-2
|
|
||||||
transport stream format (muxer @code{mpegts}).
|
|
||||||
|
|
||||||
For example to remux an MP4 file containing an H.264 stream to mpegts
|
|
||||||
format with @command{ffmpeg}, you can use the command:
|
|
||||||
|
|
||||||
@example
|
|
||||||
ffmpeg -i INPUT.mp4 -codec copy -bsf:v h264_mp4toannexb OUTPUT.ts
|
|
||||||
@end example
|
|
||||||
|
|
||||||
Please note that this filter is auto-inserted for MPEG-TS (muxer
|
|
||||||
@code{mpegts}) and raw H.264 (muxer @code{h264}) output formats.
|
|
||||||
|
|
||||||
@section hevc_mp4toannexb
|
|
||||||
|
|

Convert an HEVC/H.265 bitstream from length prefixed mode to start code
|
|
||||||
prefixed mode (as defined in the Annex B of the ITU-T H.265
|
|
||||||
specification).
|
|
||||||
|
|
||||||
This is required by some streaming formats, typically the MPEG-2
|
|

ffmpeg -i INPUT.mp4 -codec copy -bsf:v hevc_mp4toannexb OUTPUT.ts
|
|

@end example
|
|
||||||
|
|

Please note that this filter is auto-inserted for MPEG-TS (muxer

@code{mpegts}) and raw HEVC/H.265 (muxer @code{h265} or
|
|
||||||
@code{hevc}) output formats.
|
|

|
|
||||||
@section imxdump
|
|
||||||
|
|
||||||
Modifies the bitstream to fit in MOV and to be usable by the Final Cut
|
|
||||||
Pro decoder. This filter only applies to the mpeg2video codec, and is
|
|
||||||
likely not needed for Final Cut Pro 7 and newer with the appropriate
|
|
||||||
@option{-tag:v}.
|
|
||||||
|
|
||||||
For example, to remux 30 MB/sec NTSC IMX to MOV:
|
|
||||||
|
|
||||||
@example
|
|
||||||
ffmpeg -i input.mxf -c copy -bsf:v imxdump -tag:v mx3n output.mov
|
|
||||||
@end example
|
|
||||||
|
|
||||||
@section mjpeg2jpeg
|
|
||||||
|
|
||||||
Convert MJPEG/AVI1 packets to full JPEG/JFIF packets.
|
|
||||||
|
|
||||||
MJPEG is a video codec wherein each video frame is essentially a
|
|
||||||
JPEG image. The individual frames can be extracted without loss,
|
|
||||||
e.g. by
|
|
||||||
|
|
||||||
@example
|
|
||||||
ffmpeg -i ../some_mjpeg.avi -c:v copy frames_%d.jpg
|
|
||||||
@end example
|
|
||||||
|
|
||||||
Unfortunately, these chunks are incomplete JPEG images, because
|
|
||||||
they lack the DHT segment required for decoding. Quoting from
|
|
||||||
@url{http://www.digitalpreservation.gov/formats/fdd/fdd000063.shtml}:
|
|
||||||
|
|
||||||
Avery Lee, writing in the rec.video.desktop newsgroup in 2001,
|
|
||||||
commented that "MJPEG, or at least the MJPEG in AVIs having the
|
|
||||||
MJPG fourcc, is restricted JPEG with a fixed -- and *omitted* --
|
|
||||||
Huffman table. The JPEG must be YCbCr colorspace, it must be 4:2:2,
|
|
||||||
and it must use basic Huffman encoding, not arithmetic or
|
|
||||||
progressive. . . . You can indeed extract the MJPEG frames and
|
|
||||||
decode them with a regular JPEG decoder, but you have to prepend
|
|
||||||
the DHT segment to them, or else the decoder won't have any idea
|
|
||||||
how to decompress the data. The exact table necessary is given in
|
|
||||||
the OpenDML spec."
|
|
||||||
|
|
||||||
This bitstream filter patches the header of frames extracted from an MJPEG
|
|
||||||
stream (carrying the AVI1 header ID and lacking a DHT segment) to
|
|
||||||
produce fully qualified JPEG images.
|
|
||||||
|
|
||||||
@example
|
|
||||||
ffmpeg -i mjpeg-movie.avi -c:v copy -bsf:v mjpeg2jpeg frame_%d.jpg
|
|
||||||
exiftran -i -9 frame*.jpg
|
|
||||||
ffmpeg -i frame_%d.jpg -c:v copy rotated.avi
|
|
||||||
@end example
|
|
||||||
|
|
||||||
@section mjpegadump
|
|
||||||
|
|
||||||
Add an MJPEG A header to the bitstream, to enable decoding by
|
|
||||||
Quicktime.
|
|
||||||
|
|
||||||
@anchor{mov2textsub}
|
|
||||||
@section mov2textsub
|
|
||||||
|
|
||||||
Extract a representable text file from MOV subtitles, stripping the
|
|
||||||
metadata header from each subtitle packet.
|
|
||||||
|
|
||||||
See also the @ref{text2movsub} filter.
|
|
||||||
|
|
||||||
@section mp3decomp
|
|
||||||
|
|
||||||
Decompress non-standard compressed MP3 audio headers.
|
|
||||||
|
|
||||||
@section mpeg4_unpack_bframes
|
|
||||||
|
|
||||||
Unpack DivX-style packed B-frames.
|
|
||||||
|
|
||||||
DivX-style packed B-frames are not valid MPEG-4 and were only a
|
|
||||||
workaround for the broken Video for Windows subsystem.
|
|
||||||
They use more space, can cause minor AV sync issues, require more
|
|
||||||
CPU power to decode (unless the player has some decoded picture queue
|
|
||||||
to compensate the 2,0,2,0 frame per packet style) and cause
|
|
||||||
trouble if copied into a standard container like mp4 or mpeg-ps/ts,
|
|
||||||
because MPEG-4 decoders may not be able to decode them, since they are
|
|
||||||
not valid MPEG-4.
|
|
||||||
|
|
||||||
For example to fix an AVI file containing an MPEG-4 stream with
|
|
||||||
DivX-style packed B-frames using @command{ffmpeg}, you can use the command:
|
|
||||||
|
|
||||||
@example
|
|
||||||
ffmpeg -i INPUT.avi -codec copy -bsf:v mpeg4_unpack_bframes OUTPUT.avi
|
|
||||||
@end example
|
|
||||||
|
|
||||||
@section noise
|
|
||||||
|
|
||||||
Damages the contents of packets or simply drops them without damaging the
|
|
||||||
container. Can be used for fuzzing or testing error resilience/concealment.
|
|
||||||
|
|
||||||
Parameters:
|
|
||||||
@table @option
|
|
||||||
@item amount
|
|
||||||
A numeral string, whose value is related to how often output bytes will
|
|
||||||
be modified. Therefore, values below or equal to 0 are forbidden, and
|
|
||||||
the lower the more frequent bytes will be modified, with 1 meaning
|
|
||||||
every byte is modified.
|
|
||||||
@item dropamount
|
|
||||||
A numeral string, whose value is related to how often packets will be dropped.
|
|
||||||
Therefore, values below or equal to 0 are forbidden, and the lower the more
|
|
||||||
frequent packets will be dropped, with 1 meaning every packet is dropped.
|
|
||||||
@end table
|
|
||||||
|
|
||||||
The following example applies the modification to every byte but does not drop
|
|
||||||
any packets.
|
|
||||||
@example
|
|
||||||
ffmpeg -i INPUT -c copy -bsf noise[=1] output.mkv
|
|
||||||
@end example
|
|
||||||
|
|
||||||
@section null
|

|
|
||||||
|
|
||||||
Convert text subtitles to MOV subtitles (as used by the @code{mov_text}
|
|
||||||
codec) with metadata headers.
|
|
||||||
|
|
||||||
See also the @ref{mov2textsub} filter.
|
|
||||||
|
|
||||||
@section vp9_superframe
|
|
||||||
|
|
||||||
Merge VP9 invisible (alt-ref) frames back into VP9 superframes. This
|
|
||||||
fixes merging of split/segmented VP9 streams where the alt-ref frame
|
|
||||||
was split from its visible counterpart.

Decoders are configured elements in FFmpeg which allow the decoding of
|
|
||||||
multimedia streams.
|
|
||||||
|
|
||||||
When you configure your FFmpeg build, all the supported native decoders
|
|
||||||
are enabled by default. Decoders requiring an external library must be enabled
|
|
||||||
manually via the corresponding @code{--enable-lib} option. You can list all
|
|
||||||
available decoders using the configure option @code{--list-decoders}.
|
|
||||||
|
|
||||||
You can disable all the decoders with the configure option
|
|
||||||
@code{--disable-decoders} and selectively enable / disable single decoders
|

with the options @code{--enable-decoder=@var{DECODER}} /
|
|
||||||
@code{--disable-decoder=@var{DECODER}}.
|

This codec decodes the bitmap subtitles used in DVDs; the same subtitles can
|
|

also be found in VobSub file pairs and in some Matroska files.
|

|
|
||||||
@subsection Options
|
|
||||||
|
|
||||||
@table @option
|
|
||||||
@item palette
|
|
||||||
Specify the global palette used by the bitmaps. When stored in VobSub, the
|
|
||||||
palette is normally specified in the index file; in Matroska, the palette is
|
|
||||||
stored in the codec extra-data in the same format as in VobSub. In DVDs, the
|
|
||||||
palette is stored in the IFO file, and therefore not available when reading
|
|
||||||
from dumped VOB files.
|
|
||||||
|
|
||||||
The format for this option is a string containing 16 24-bits hexadecimal
|
|
||||||
numbers (without 0x prefix) separated by comas, for example @code{0d00ee,
|
|
||||||
ee450d, 101010, eaeaea, 0ce60b, ec14ed, ebff0b, 0d617a, 7b7b7b, d1d1d1,
|
|
||||||
7b2a0e, 0d950c, 0f007b, cf0dec, cfa80c, 7c127b}.
|
|
||||||
|
|
||||||
@item ifo_palette
|
|
||||||
Specify the IFO file from which the global palette is obtained.
|
|
||||||
(experimental)
|
|
||||||
|
|
||||||
@item forced_subs_only
|
|
||||||
Only decode subtitle entries marked as forced. Some titles have forced
|
|
||||||
and non-forced subtitles in the same track. Setting this flag to @code{1}
|
|
||||||
will only keep the forced subtitles. Default value is @code{0}.

Libzvbi allows libavcodec to decode DVB teletext pages and DVB teletext
|
|
||||||
subtitles. Requires the presence of the libzvbi headers and library during
|
|
||||||
configuration. You need to explicitly configure the build with
|
|
||||||
@code{--enable-libzvbi}.

@subsection Options
|
|
||||||
|
|
||||||
@table @option
|
|
||||||
@item txt_page
|
|
||||||
List of teletext page numbers to decode. You may use the special * string to
|
|
||||||
match all pages. Pages that do not match the specified list are dropped.
|
|
||||||
Default value is *.
|
|
||||||
@item txt_chop_top
|
|
||||||
Discards the top teletext line. Default value is 1.
|
|
||||||
@item txt_format
|
|
||||||
Specifies the format of the decoded subtitles. The teletext decoder is capable
|
|
||||||
of decoding the teletext pages to bitmaps or to simple text, you should use
|
|
||||||
"bitmap" for teletext pages, because certain graphics and colors cannot be
|
|
||||||
expressed in simple text. You might use "text" for teletext based subtitles if
|
|
||||||
your application can handle simple text based subtitles. Default value is
|
|
||||||
bitmap.
|
|
||||||
@item txt_left
|
|
||||||
X offset of generated bitmaps, default is 0.
|
|
||||||
@item txt_top
|
|
||||||
Y offset of generated bitmaps, default is 0.
|
|
||||||
@item txt_chop_spaces
|
|
||||||
Chops leading and trailing spaces and removes empty lines from the generated
|
|
||||||
text. This option is useful for teletext based subtitles where empty spaces may
|
|
||||||
be present at the start or at the end of the lines or empty lines may be
|
|
||||||
present between the subtitle lines because of double-sized teletext characters.
|
|
||||||
Default value is 1.
|
|
||||||
@item txt_duration
|
|
||||||
Sets the display duration of the decoded teletext pages or subtitles in
|
|
||||||
milliseconds. Default value is 30000 which is 30 seconds.
|
|
||||||
@item txt_transparent
|
|
||||||
Force transparent background of the generated teletext bitmaps. Default value
|
|
||||||
is 0 which means an opaque background.
|
|
||||||
@item txt_opacity
|
|
||||||
Sets the opacity (0-255) of the teletext background. If
|
|
||||||
@option{txt_transparent} is not set, it only affects characters between a start
|
|
||||||
box and an end box, typically subtitles. Default value is 0 if
|
|
||||||
@option{txt_transparent} is set, 255 otherwise.

@chapter Demuxers
|
|
||||||
@c man begin DEMUXERS
|
|
||||||
|
|
||||||
Demuxers are configured elements in FFmpeg that can read the
|
|
||||||
multimedia streams from a particular type of file.
|
|
||||||
|
|
||||||
When you configure your FFmpeg build, all the supported demuxers
|
|
||||||
are enabled by default. You can list all available ones using the
|
|
||||||
configure option @code{--list-demuxers}.
|
|
||||||
|
|
||||||
You can disable all the demuxers using the configure option
|
|
||||||
@code{--disable-demuxers}, and selectively enable a single demuxer with
|
|
||||||
the option @code{--enable-demuxer=@var{DEMUXER}}, or disable it
|
|
||||||
with the option @code{--disable-demuxer=@var{DEMUXER}}.
|
|
||||||
|
|
||||||
The option @code{-demuxers} of the ff* tools will display the list of
|
|
||||||
enabled demuxers. Use @code{-formats} to view a combined list of
|
|
||||||
enabled demuxers and muxers.
|
|
||||||
|
|
||||||
The description of some of the currently available demuxers follows.
|
|
||||||
|
|
||||||
@section aa
|
|
||||||
|
|
||||||
Audible Format 2, 3, and 4 demuxer.
|
|
||||||
|
|
||||||
This demuxer is used to demux Audible Format 2, 3, and 4 (.aa) files.
|
|
||||||
|
|
||||||
@section applehttp
|
|
||||||
|
|
||||||
Apple HTTP Live Streaming demuxer.
|
|
||||||
|
|
||||||
This demuxer presents all AVStreams from all variant streams.
|
|
||||||
The id field is set to the bitrate variant index number. By setting
|
|
||||||
the discard flags on AVStreams (by pressing 'a' or 'v' in ffplay),
|
|
||||||
the caller can decide which variant streams to actually receive.
|
|
||||||
The total bitrate of the variant that the stream belongs to is
|
|
||||||
available in a metadata key named "variant_bitrate".
|
|
||||||
|
|
||||||
@section apng
|
|
||||||
|
|
||||||
Animated Portable Network Graphics demuxer.
|
|
||||||
|
|
||||||
This demuxer is used to demux APNG files.
|
|
||||||
All headers, but the PNG signature, up to (but not including) the first
|
|
||||||
fcTL chunk are transmitted as extradata.
|
|
||||||
Frames are then split as being all the chunks between two fcTL ones, or
|
|
||||||
between the last fcTL and IEND chunks.
|
|
||||||
|
|
||||||
@table @option
|
|
||||||
@item -ignore_loop @var{bool}
|
|
||||||
Ignore the loop variable in the file if set.
|
|
||||||
@item -max_fps @var{int}
|
|
||||||
Maximum framerate in frames per second (0 for no limit).
|
|
||||||
@item -default_fps @var{int}
|
|
||||||
Default framerate in frames per second when none is specified in the file
|
|
||||||
(0 meaning as fast as possible).
|
|
||||||
@end table
|
|
||||||
|
|
||||||
@section asf
|
|
||||||
|
|
||||||
Advanced Systems Format demuxer.
|
|
||||||
|
|
||||||
This demuxer is used to demux ASF files and MMS network streams.
|
|
||||||
|
|
||||||
@table @option
|
|
||||||
@item -no_resync_search @var{bool}
|
|
||||||
Do not try to resynchronize by looking for a certain optional start code.
|
|
||||||
@end table
|
|
||||||
|
|
||||||
@anchor{concat}
|
|
||||||
@section concat
|
|
||||||
|
|
||||||
Virtual concatenation script demuxer.
|
|
||||||
|
|
||||||
This demuxer reads a list of files and other directives from a text file and
|
|
||||||
demuxes them one after the other, as if all their packets had been muxed
|
|
||||||
together.
|
|
||||||
|
|
||||||
The timestamps in the files are adjusted so that the first file starts at 0
|
|
||||||
and each next file starts where the previous one finishes. Note that it is
|
|
||||||
done globally and may cause gaps if all streams do not have exactly the same
|
|
||||||
length.
|
|
||||||
|
|
||||||
All files must have the same streams (same codecs, same time base, etc.).
|
|
||||||
|
|
||||||
The duration of each file is used to adjust the timestamps of the next file:
|
|
||||||
if the duration is incorrect (because it was computed using the bit-rate or
|
|
||||||
because the file is truncated, for example), it can cause artifacts. The
|
|
||||||
@code{duration} directive can be used to override the duration stored in
|
|
||||||
each file.
|
|
||||||
|
|
||||||
@subsection Syntax
|
|
||||||
|
|
||||||
The script is a text file in extended-ASCII, with one directive per line.
|
|
||||||
Empty lines, leading spaces and lines starting with '#' are ignored. The
|
|
||||||
following directive is recognized:
|
|
||||||
|
|
||||||
@table @option
|
|
||||||
|
|
||||||
@item @code{file @var{path}}
|
|
||||||
Path to a file to read; special characters and spaces must be escaped with
|
|
||||||
backslash or single quotes.
|
|
||||||
|
|
||||||
All subsequent file-related directives apply to that file.
|
|
||||||
|
|
||||||
@item @code{ffconcat version 1.0}
|
|
||||||
Identify the script type and version. It also sets the @option{safe} option
|
|
||||||
to 1 if it was -1.
|
|
||||||
|
|
||||||
To make FFmpeg recognize the format automatically, this directive must
|
|
||||||
appear exactly as is (no extra space or byte-order-mark) on the very first
|
|
||||||
line of the script.
|
|
||||||
|
|
||||||
@item @code{duration @var{dur}}
|
|
||||||
Duration of the file. This information can be specified from the file;
|
|
||||||
specifying it here may be more efficient or help if the information from the
|
|
||||||
file is not available or accurate.
|
|
||||||
|
|
||||||
If the duration is set for all files, then it is possible to seek in the
|
|
||||||
whole concatenated video.
|
|
||||||
|
|
||||||
@item @code{inpoint @var{timestamp}}
|
|
||||||
In point of the file. When the demuxer opens the file it instantly seeks to the
|
|
||||||
specified timestamp. Seeking is done so that all streams can be presented
|
|
||||||
successfully at In point.
|
|
||||||
|
|
||||||
This directive works best with intra frame codecs, because for non-intra frame
|
|
||||||
ones you will usually get extra packets before the actual In point and the
|
|
||||||
decoded content will most likely contain frames before In point too.
|
|
||||||
|
|
||||||
For each file, packets before the file In point will have timestamps less than
|
|
||||||
the calculated start timestamp of the file (negative in case of the first
|
|
||||||
file), and the duration of the files (if not specified by the @code{duration}
|
|
||||||
directive) will be reduced based on their specified In point.
|
|
||||||
|
|
||||||
Because of potential packets before the specified In point, packet timestamps
|
|
||||||
may overlap between two concatenated files.
|
|
||||||
|
|
||||||
@item @code{outpoint @var{timestamp}}
|
|
||||||
Out point of the file. When the demuxer reaches the specified decoding
|
|
||||||
timestamp in any of the streams, it handles it as an end of file condition and
|
|
||||||
skips the current and all the remaining packets from all streams.
|
|
||||||
|
|
||||||
Out point is exclusive, which means that the demuxer will not output packets
|
|
||||||
with a decoding timestamp greater or equal to Out point.
|
|
||||||
|
|
||||||
This directive works best with intra frame codecs and formats where all streams
|
|
||||||
are tightly interleaved. For non-intra frame codecs you will usually get
|
|
||||||
additional packets with presentation timestamp after Out point therefore the
|
|
||||||
decoded content will most likely contain frames after Out point too. If your
|
|
||||||
streams are not tightly interleaved you may not get all the packets from all
|
|
||||||
streams before Out point and you may only will be able to decode the earliest
|
|
||||||
stream until Out point.
|
|
||||||
|
|
||||||
The duration of the files (if not specified by the @code{duration}
|
|
||||||
directive) will be reduced based on their specified Out point.
|
|
||||||
|
|
||||||
@item @code{file_packet_metadata @var{key=value}}
|
|
||||||
Metadata of the packets of the file. The specified metadata will be set for
|
|
||||||
each file packet. You can specify this directive multiple times to add multiple
|
|
||||||
metadata entries.
|
|
||||||
|
|
||||||
@item @code{stream}
|
|
||||||
Introduce a stream in the virtual file.
|
|
||||||
All subsequent stream-related directives apply to the last introduced
|
|
||||||
stream.
|
|
||||||
Some streams properties must be set in order to allow identifying the
|
|
||||||
matching streams in the subfiles.
|
|
||||||
If no streams are defined in the script, the streams from the first file are
|
|
||||||
copied.
|
|
||||||
|
|
||||||
@item @code{exact_stream_id @var{id}}
|
|
||||||
Set the id of the stream.
|
|
||||||
If this directive is given, the string with the corresponding id in the
|
|
||||||
subfiles will be used.
|
|
||||||
This is especially useful for MPEG-PS (VOB) files, where the order of the
|
|
||||||
streams is not reliable.

@subsection Options
|
|

|
|
||||||
This demuxer accepts the following option:
|
|
||||||
|
|
||||||
@table @option
|
|
||||||
|
|
||||||
@item safe
|
|
||||||
If set to 1, reject unsafe file paths. A file path is considered safe if it
|
|
||||||
does not contain a protocol specification and is relative and all components
|
|
||||||
only contain characters from the portable character set (letters, digits,
|
|
||||||
period, underscore and hyphen) and have no period at the beginning of a
|
|
||||||
component.
|
|
||||||
|
|
||||||
If set to 0, any file name is accepted.
|
|
||||||
|
|
||||||
The default is 1.
|
|
||||||
|
|
||||||
-1 is equivalent to 1 if the format was automatically
|
|
||||||
probed and 0 otherwise.
|
|
||||||
|
|
||||||
@item auto_convert
|
|
||||||
If set to 1, try to perform automatic conversions on packet data to make the
|
|
||||||
streams concatenable.
|
|
||||||
The default is 1.
|
|
||||||
|
|
||||||
Currently, the only conversion is adding the h264_mp4toannexb bitstream
|
|
||||||
filter to H.264 streams in MP4 format. This is necessary in particular if
|
|
||||||
there are resolution changes.
|
|
||||||
|
|
||||||
@item segment_time_metadata
|
|
||||||
If set to 1, every packet will contain the @var{lavf.concat.start_time} and the
|
|
||||||
@var{lavf.concat.duration} packet metadata values which are the start_time and
|
|
||||||
the duration of the respective file segments in the concatenated output
|
|
||||||
expressed in microseconds. The duration metadata is only set if it is known
|
|
||||||
based on the concat file.
|
|
||||||
The default is 0.

Adobe Flash Video Format demuxer.
|
|
||||||
|
|
||||||
This demuxer is used to demux FLV files and RTMP network streams. In case of live network streams, if you force format, you may use live_flv option instead of flv to survive timestamp discontinuities.
|
|
||||||
|
|
||||||
@example
|
|
||||||
ffmpeg -f flv -i myfile.flv ...
|
|
||||||
ffmpeg -f live_flv -i rtmp://<any.server>/anything/key ....

||||||
|
|
||||||
|
|
||||||
@table @option
|
|

@section gif
|
|
||||||
|
|
||||||
Animated GIF demuxer.
|
|
||||||
|
|
||||||
It accepts the following options:
|
|
||||||
|
|
||||||
@table @option
|
|
||||||
@item min_delay
|
|
||||||
Set the minimum valid delay between frames in hundredths of seconds.
|
|
||||||
Range is 0 to 6000. Default value is 2.
|
|
||||||
|
|
||||||
@item max_gif_delay
|
|
||||||
Set the maximum valid delay between frames in hundredth of seconds.
|
|
||||||
Range is 0 to 65535. Default value is 65535 (nearly eleven minutes),
|
|
||||||
the maximum value allowed by the specification.
|
|
||||||
|
|
||||||
@item default_delay
|
|
||||||
Set the default delay between frames in hundredths of seconds.
|
|
||||||
Range is 0 to 6000. Default value is 10.
|
|
||||||
|
|
||||||
@item ignore_loop
|
|
||||||
GIF files can contain information to loop a certain number of times (or
|
|
||||||
infinitely). If @option{ignore_loop} is set to 1, then the loop setting
|
|
||||||
from the input will be ignored and looping will not occur. If set to 0,
|
|
||||||
then looping will occur and will cycle the number of times according to
|
|
||||||
the GIF. Default value is 1.
|
|
||||||
@end table
|
|
||||||
|
|
||||||
For example, with the overlay filter, place an infinitely looping GIF
|
|
||||||
over another video:
|
|
||||||
@example
|
|
||||||
ffmpeg -i input.mp4 -ignore_loop 0 -i input.gif -filter_complex overlay=shortest=1 out.mkv
|
|
||||||
@end example
|
|
||||||
|
|
||||||
Note that in the above example the shortest option for overlay filter is
|
|
||||||
used to end the output video at the length of the shortest input file,
|
|
||||||
which in this case is @file{input.mp4} as the GIF in this example loops
|
|
||||||
infinitely.
|
|
||||||

|
|
||||||
|
|
||||||
@item allowed_extensions
|
|
||||||
',' separated list of file extensions that hls is allowed to access.
|
|
||||||
|
|
||||||
@item max_reload
|

@section image2
|
|

|
|
||||||
Image file demuxer.
|
|
||||||
|
|
||||||
This demuxer reads from a list of image files specified by a pattern.
|
|
||||||
The syntax and meaning of the pattern is specified by the
|
|
||||||
option @var{pattern_type}.
|
|
||||||
|
|
||||||
The pattern may contain a suffix which is used to automatically
|
|
||||||
determine the format of the images contained in the files.
|
|
||||||
|
|
||||||
The size, the pixel format, and the format of each image must be the
|
|
||||||
same for all the files in the sequence.
|
|
||||||
|
|
||||||
This demuxer accepts the following options:
|
|
||||||
@table @option
|
|
||||||
@item framerate
|
|
||||||
Set the frame rate for the video stream. It defaults to 25.
|
|
||||||
@item loop
|
|
||||||
If set to 1, loop over the input. Default value is 0.
|
|
||||||
@item pattern_type
|
|
||||||
Select the pattern type used to interpret the provided filename.
|
|
||||||
|
|
||||||
@var{pattern_type} accepts one of the following values.
|
|
||||||
@table @option
|
|
||||||
@item none
|
|
||||||
Disable pattern matching, therefore the video will only contain the specified
|
|
||||||
image. You should use this option if you do not want to create sequences from
|
|
||||||
multiple images and your filenames may contain special pattern characters.
|
|
||||||
@item sequence
|
|
||||||
Select a sequence pattern type, used to specify a sequence of files
|
|
||||||
indexed by sequential numbers.
|
|
||||||
|
|
||||||
A sequence pattern may contain the string "%d" or "%0@var{N}d", which
|
|
||||||
specifies the position of the characters representing a sequential
|
|
||||||
number in each filename matched by the pattern. If the form
|
|
||||||
"%d0@var{N}d" is used, the string representing the number in each
|
|
||||||
filename is 0-padded and @var{N} is the total number of 0-padded
|
|
||||||
digits representing the number. The literal character '%' can be
|
|
||||||
specified in the pattern with the string "%%".
|
|
||||||
|
|
||||||
If the sequence pattern contains "%d" or "%0@var{N}d", the first filename of
|
|
||||||
the file list specified by the pattern must contain a number
|
|
||||||
inclusively contained between @var{start_number} and
|
|
||||||
@var{start_number}+@var{start_number_range}-1, and all the following
|
|
||||||
numbers must be sequential.
|
|
||||||
|
|
||||||
For example the pattern "img-%03d.bmp" will match a sequence of
|
|
||||||
filenames of the form @file{img-001.bmp}, @file{img-002.bmp}, ...,
|
|
||||||
@file{img-010.bmp}, etc.; the pattern "i%%m%%g-%d.jpg" will match a
|
|
||||||
sequence of filenames of the form @file{i%m%g-1.jpg},
|
|
||||||
@file{i%m%g-2.jpg}, ..., @file{i%m%g-10.jpg}, etc.
|
|
||||||
|
|
||||||
Note that the pattern must not necessarily contain "%d" or
|
|
||||||
"%0@var{N}d", for example to convert a single image file
|
|
||||||
@file{img.jpeg} you can employ the command:
|
|
||||||
@example
|
|
||||||
ffmpeg -i img.jpeg img.png
|
|
||||||
@end example
|
|
||||||
|
|
||||||
@item glob
|
|
||||||
Select a glob wildcard pattern type.
|
|
||||||
|
|
||||||
The pattern is interpreted like a @code{glob()} pattern. This is only
|
|
||||||
selectable if libavformat was compiled with globbing support.
|
|
||||||
|
|
||||||
@item glob_sequence @emph{(deprecated, will be removed)}
|
|
||||||
Select a mixed glob wildcard/sequence pattern.
|
|
||||||
|
|
||||||
If your version of libavformat was compiled with globbing support, and
|
|
||||||
the provided pattern contains at least one glob meta character among
|
|
||||||
@code{%*?[]@{@}} that is preceded by an unescaped "%", the pattern is
|
|
||||||
interpreted like a @code{glob()} pattern, otherwise it is interpreted
|
|
||||||
like a sequence pattern.
|
|
||||||
|
|
||||||
All glob special characters @code{%*?[]@{@}} must be prefixed
|
|
||||||
with "%". To escape a literal "%" you shall use "%%".
|
|
||||||
|
|
||||||
For example the pattern @code{foo-%*.jpeg} will match all the
|
|
||||||
filenames prefixed by "foo-" and terminating with ".jpeg", and
|
|
||||||
@code{foo-%?%?%?.jpeg} will match all the filenames prefixed with
|
|
||||||
"foo-", followed by a sequence of three characters, and terminating
|
|
||||||
with ".jpeg".
|
|
||||||
|
|
||||||
This pattern type is deprecated in favor of @var{glob} and
|
|
||||||
@var{sequence}.
|
|
||||||
@end table
|
|
||||||
|
|
||||||
Default value is @var{glob_sequence}.
|
|
||||||
@item pixel_format
|
|
||||||
Set the pixel format of the images to read. If not specified the pixel
|
|
||||||
format is guessed from the first image file in the sequence.
|
|
||||||
@item start_number
|
|
||||||
Set the index of the file matched by the image file pattern to start
|
|
||||||
to read from. Default value is 0.
|
|
||||||
@item start_number_range
|
|
||||||
Set the index interval range to check when looking for the first image
|
|
||||||
file in the sequence, starting from @var{start_number}. Default value
|
|
||||||
is 5.
|
|
||||||
@item ts_from_file
|
|
||||||
If set to 1, will set frame timestamp to modification time of image file. Note
|
|
||||||
that monotonity of timestamps is not provided: images go in the same order as
|
|
||||||
without this option. Default value is 0.
|
|
||||||
If set to 2, will set frame timestamp to the modification time of the image file in
|
|
||||||
nanosecond precision.
|
|
||||||
@item video_size
|
|
||||||
Set the video size of the images to read. If not specified the video
|
|
||||||
size is guessed from the first image file in the sequence.

@item strict_mime_boundary
|
|
||||||
Default implementation applies a relaxed standard to multi-part MIME boundary detection,
|
|
||||||
to prevent regression with numerous existing endpoints not generating a proper MIME
|
|
||||||
MJPEG stream. Turning this option on by setting it to 1 will result in a stricter check
|
|
||||||
of the boundary value.
|
|
||||||
@end table
|
|

|
|

@section rawvideo
|
|
||||||
|
|
||||||
Raw video demuxer.
|
|
||||||
|
|
||||||
This demuxer allows one to read raw video data. Since there is no header
|
|
||||||
specifying the assumed video parameters, the user must specify them
|
|
||||||
in order to be able to decode the data correctly.
|
|
||||||
|
|
||||||
This demuxer accepts the following options:
|
|
||||||
@table @option
|
|
||||||
|
|
||||||
@item framerate
|
|
||||||
Set input video frame rate. Default value is 25.
|
|
||||||
|
|
||||||
@item pixel_format
|
|
||||||
Set the input video pixel format. Default value is @code{yuv420p}.
|
|
||||||
|
|
||||||
@item video_size
|
|
||||||
Set the input video size. This value must be specified explicitly.
|
|
||||||
@end table
|
|
||||||
|
|
||||||
For example to read a rawvideo file @file{input.raw} with
|
|
||||||
@command{ffplay}, assuming a pixel format of @code{rgb24}, a video
|
|
||||||
size of @code{320x240}, and a frame rate of 10 images per second, use
|
|
||||||
the command:
|
|
||||||
@example
|
|
||||||
ffplay -f rawvideo -pixel_format rgb24 -video_size 320x240 -framerate 10 input.raw
|
|
||||||
@end example
|
|
||||||
|
|
||||||
@section sbg
|
|
||||||
|
|
||||||
SBaGen script demuxer.
|
|
||||||
|
|
||||||
This demuxer reads the script language used by SBaGen
|
|
||||||
@url{http://uazu.net/sbagen/} to generate binaural beats sessions. A SBG
|
|
||||||
script looks like that:
|
|
||||||
@example
|
|
||||||
-SE
|
|
||||||
a: 300-2.5/3 440+4.5/0
|
|
||||||
b: 300-2.5/0 440+4.5/3
|
|
||||||
off: -
|
|
||||||
NOW == a
|
|
||||||
+0:07:00 == b
|
|
||||||
+0:14:00 == a
|
|
||||||
+0:21:00 == b
|
|
||||||
+0:30:00 off
|
|
||||||
@end example
|
|
||||||
|
|
||||||
A SBG script can mix absolute and relative timestamps. If the script uses
|
|
||||||
either only absolute timestamps (including the script start time) or only
|
|
||||||
relative ones, then its layout is fixed, and the conversion is
|
|
||||||
straightforward. On the other hand, if the script mixes both kind of
|
|
||||||
timestamps, then the @var{NOW} reference for relative timestamps will be
|
|
||||||
taken from the current time of day at the time the script is read, and the
|
|
||||||
script layout will be frozen according to that reference. That means that if
|
|
||||||
the script is directly played, the actual times will match the absolute
|
|
||||||
timestamps up to the sound controller's clock accuracy, but if the user
|
|
||||||
somehow pauses the playback or seeks, all times will be shifted accordingly.
|
|
||||||
|
|
||||||
@section tedcaptions
|
|
||||||
|
|
||||||
JSON captions used for @url{http://www.ted.com/, TED Talks}.
|
|
||||||
|
|
||||||
TED does not provide links to the captions, but they can be guessed from the
|
|
||||||
page. The file @file{tools/bookmarklets.html} from the FFmpeg source tree
|
|
||||||
contains a bookmarklet to expose them.
|
|
||||||
|
|
||||||
This demuxer accepts the following option:
|
|
||||||
@table @option
|
|
||||||
@item start_time
|
|
||||||
Set the start time of the TED talk, in milliseconds. The default is 15000
|
|
||||||
(15s). It is used to sync the captions with the downloadable videos, because
|
|
||||||
they include a 15s intro.
|
|
||||||
@end table
|
|
||||||
|
|
||||||
Example: convert the captions to a format most players understand:
|
|
||||||
@example
|
|
||||||
ffmpeg -i http://www.ted.com/talks/subtitles/id/1/lang/en talk1-en.srt

|
||||||
@section Notes for external developers
|
|
||||||
|
|
||||||
This document is mostly useful for internal FFmpeg developers.
|
|
||||||
External developers who need to use the API in their application should
|
|
||||||
refer to the API doxygen documentation in the public headers, and
|
|
||||||
check the examples in @file{doc/examples} and in the source code to
|
|
||||||
see how the public API is employed.
|
|
||||||
|
|
||||||
You can use the FFmpeg libraries in your commercial program, but you
|
|
||||||
are encouraged to @emph{publish any patch you make}. In this case the
|
|
||||||
best way to proceed is to send your patches to the ffmpeg-devel
|
|
||||||
mailing list following the guidelines illustrated in the remainder of
|
|
||||||
this document.
|
|
||||||
|
|
||||||
For more detailed legal information about the use of FFmpeg in
|
|
||||||
external programs read the @file{LICENSE} file in the source tree and
|
|
||||||
consult @url{https://ffmpeg.org/legal.html}.
|
|
||||||
|
|
||||||
@section Contributing
|
|
||||||
|
|
||||||
There are 3 ways by which code gets into FFmpeg.
|
|
||||||
@itemize @bullet
|
|
||||||
@item Submitting patches to the main developer mailing list.
|
|
||||||
See @ref{Submitting patches} for details.
|
|
||||||
@item Directly committing changes to the main tree.
|
|
||||||
@item Committing changes to a git clone, for example on github.com or
|
|
||||||
gitorious.org. And asking us to merge these changes.
|
|
||||||
@end itemize
|
|
||||||
|
|
||||||
Whichever way, changes should be reviewed by the maintainer of the code
|
|
||||||
before they are committed. And they should follow the @ref{Coding Rules}.
|
|
||||||
The developer making the commit and the author are responsible for their changes
|
|
||||||
and should try to fix issues their commit causes.
|
|
||||||

|
||||||
@section Coding Rules
|
|
||||||
|
|
||||||
@subsection Code formatting conventions
|
|
||||||
|
|
||||||
There are the following guidelines regarding the indentation in files:
|
|
||||||
|
|
||||||
@itemize @bullet
|
|
||||||
@item
|
|
||||||
Indent size is 4.
|
|
||||||
|
|
||||||
@item
|
|
||||||
The TAB character is forbidden outside of Makefiles as is any
|
|
||||||
form of trailing whitespace. Commits containing either will be
|
|
||||||
rejected by the git repository.
|
|
||||||
|
|
||||||
@item
|
|
||||||
You should try to limit your code lines to 80 characters; however, do so if
|
|
||||||
and only if this improves readability.
|
|
||||||
|
|
||||||
@item
|
|
||||||
K&R coding style is used.
|
|
||||||
@end itemize
|
|
||||||
The presentation is one inspired by 'indent -i4 -kr -nut'.
|
|
||||||
|
|
||||||
The main priority in FFmpeg is simplicity and small code size in order to
|
|
||||||
minimize the bug count.
|
|
||||||
|
|
||||||
@subsection Comments
|
|
||||||
Use the JavaDoc/Doxygen format (see examples below) so that code documentation
|
|
||||||
can be generated automatically. All nontrivial functions should have a comment
|
|
||||||
above them explaining what the function does, even if it is just one sentence.
|
|
||||||
All structures and their member variables should be documented, too.
|
|
||||||
|
|
||||||
Avoid Qt-style and similar Doxygen syntax with @code{!} in it, i.e. replace
|
|
||||||
@code{//!} with @code{///} and similar. Also @@ syntax should be employed
|
|
||||||
for markup commands, i.e. use @code{@@param} and not @code{\param}.
|
|
||||||
|
|
||||||
@example
|
|
||||||
/**
|
|
||||||
* @@file
|
|
||||||
* MPEG codec.
|
|
||||||

@end example

@subsection C language features
|
|
||||||
|
|
||||||
FFmpeg is programmed in the ISO C90 language with a few additional
|
|
||||||
features from ISO C99, namely:
|
|
||||||
|
|
||||||
@itemize @bullet
|
|
||||||
@item
|
|
||||||
the @samp{inline} keyword;
|
|
||||||
|
|
||||||
@item
|
|
||||||
@samp{//} comments;
|
|
||||||
|
|
||||||
@item
|
|
||||||
designated struct initializers (@samp{struct s x = @{ .i = 17 @};});
|
|
||||||
|
|
||||||
@item
|
|
||||||
compound literals (@samp{x = (struct s) @{ 17, 23 @};}).
|
|
||||||
|
|
||||||
@item
|
|
||||||
Implementation defined behavior for signed integers is assumed to match the
|
|
||||||
expected behavior for two's complement. Non representable values in integer
|
|
||||||
casts are binary truncated. Shift right of signed values uses sign extension.
|
|
||||||
@end itemize
|
|
||||||
|
|
||||||
These features are supported by all compilers we care about, so we will not
|
|
||||||
accept patches to remove their use unless they absolutely do not impair
|
|
||||||
clarity and performance.
|
|
||||||
|
|
||||||
All code must compile with recent versions of GCC and a number of other
|
|
||||||
currently supported compilers. To ensure compatibility, please do not use
|
|
||||||
additional C99 features or GCC extensions. Especially watch out for:
|
|
||||||
|
|
||||||
@itemize @bullet
|
|
||||||
@item
|
|
||||||
mixing statements and declarations;
|
|
||||||
|
|
||||||
@item
|
|
||||||
@samp{long long} (use @samp{int64_t} instead);
|
|
||||||
|
|
||||||
@item
|
|
||||||
@samp{__attribute__} not protected by @samp{#ifdef __GNUC__} or similar;
|
|
||||||
|
|
||||||
@item
|
|
||||||
GCC statement expressions (@samp{(x = (@{ int y = 4; y; @})}).
|
|
||||||
@end itemize
|
|
||||||
|
|
||||||
@subsection Naming conventions
|
|
||||||
All names should be composed with underscores (_), not CamelCase. For example,
|
|
||||||
@samp{avfilter_get_video_buffer} is an acceptable function name and
|
|
||||||
@samp{AVFilterGetVideo} is not. The exception from this are type names, like
|
|
||||||
for example structs and enums; they should always be in CamelCase.
|
|
||||||
|
|
||||||
There are the following conventions for naming variables and functions:
|
|
||||||
|
|
||||||
@itemize @bullet
|
|
||||||
@item
|
|
||||||
For local variables no prefix is required.
|
|
||||||
|
|
||||||
@item
|
|
||||||
For file-scope variables and functions declared as @code{static}, no prefix
|
|
||||||
is required.
|
|
||||||
|
|
||||||
@item
|
|
||||||
For variables and functions visible outside of file scope, but only used
|
|
||||||
internally by a library, an @code{ff_} prefix should be used,
|
|
||||||
e.g. @samp{ff_w64_demuxer}.
|
|
||||||
|
|
||||||
@item
|
|
||||||
For variables and functions visible outside of file scope, used internally
|
|
||||||
across multiple libraries, use @code{avpriv_} as prefix, for example,
|
|
||||||
@samp{avpriv_aac_parse_header}.
|
|
||||||
|
|
||||||
@item
|
|
||||||
Each library has its own prefix for public symbols, in addition to the
|
|
||||||
commonly used @code{av_} (@code{avformat_} for libavformat,
|
|
||||||
@code{avcodec_} for libavcodec, @code{swr_} for libswresample, etc).
|
|
||||||
Check the existing code and choose names accordingly.
|
|
||||||
Note that some symbols without these prefixes are also exported for
|
|
||||||
retro-compatibility reasons. These exceptions are declared in the
|
|
||||||
@code{lib<name>/lib<name>.v} files.
|
|
||||||
@end itemize
|
|
||||||
|
|
||||||
Furthermore, name space reserved for the system should not be invaded.
|
|
||||||
Identifiers ending in @code{_t} are reserved by
|
|
||||||
@url{http://pubs.opengroup.org/onlinepubs/007904975/functions/xsh_chap02_02.html#tag_02_02_02, POSIX}.
|
|
||||||
Also avoid names starting with @code{__} or @code{_} followed by an uppercase
|
|
||||||
letter as they are reserved by the C standard. Names starting with @code{_}
|
|
||||||
are reserved at the file level and may not be used for externally visible
|
|
||||||
symbols. If in doubt, just avoid names starting with @code{_} altogether.
|
|
||||||
|
|
||||||
@subsection Miscellaneous conventions
|
|
||||||
|
|
||||||
@itemize @bullet
|
|
||||||
@item
|
|
||||||
fprintf and printf are forbidden in libavformat and libavcodec,
|
|
||||||
please use av_log() instead.
|
|
||||||
|
|
||||||
@item
|
|
||||||
Casts should be used only when necessary. Unneeded parentheses
|
|
||||||
should also be avoided if they don't make the code easier to understand.
|
|
||||||
@end itemize
|
|
||||||
|
|
||||||
@subsection Editor configuration
|
|
||||||
In order to configure Vim to follow FFmpeg formatting conventions, paste
|
|
||||||
the following snippet into your @file{.vimrc}:
|
|
||||||
@example
|
|
||||||
" indentation rules for FFmpeg: 4 spaces, no tabs
|
|
||||||
set expandtab
|
|
||||||
set shiftwidth=4
|
|
||||||
set softtabstop=4
|
|
||||||
set cindent
|
|
||||||
set cinoptions=(0
|
|
||||||
" Allow tabs in Makefiles.
|
|
||||||
autocmd FileType make,automake set noexpandtab shiftwidth=8 softtabstop=8
|
|
||||||
" Trailing whitespace and tabs are forbidden, so highlight them.
|
|
||||||
highlight ForbiddenWhitespace ctermbg=red guibg=red
|
|
||||||
match ForbiddenWhitespace /\s\+$\|\t/
|
|
||||||
" Do not highlight spaces at the end of line while typing on that line.
|
|
||||||
autocmd InsertEnter * match ForbiddenWhitespace /\t\|\s\+\%#\@@<!$/
|
|
||||||
@end example
|
|
||||||
|
|
||||||
For Emacs, add these roughly equivalent lines to your @file{.emacs.d/init.el}:
|
|
||||||
@lisp
|
|
||||||
(c-add-style "ffmpeg"
|
|
||||||
'("k&r"
|
|
||||||

)
|
|
||||||
(setq c-default-style "ffmpeg")
|
|
||||||
@end lisp

|
||||||
@section Development Policy
|
|
||||||
|
|
||||||
@subsection Patches/Committing
|
|
||||||
@subheading Licenses for patches must be compatible with FFmpeg.
|
|
||||||
Contributions should be licensed under the
|
|
||||||
@uref{http://www.gnu.org/licenses/lgpl-2.1.html, LGPL 2.1},
|
|
||||||
including an "or any later version" clause, or, if you prefer
|
|
||||||
a gift-style license, the
|
|
||||||
@uref{http://opensource.org/licenses/isc-license.txt, ISC} or
|
|
||||||
@uref{http://mit-license.org/, MIT} license.
|
|
||||||
@uref{http://www.gnu.org/licenses/gpl-2.0.html, GPL 2} including
|
|
||||||
an "or any later version" clause is also acceptable, but LGPL is
|
|
||||||
preferred.
|
|
||||||
If you add a new file, give it a proper license header. Do not copy and
|
|
||||||
paste it from a random place, use an existing file as template.
|
|
||||||
|
|
||||||
@subheading You must not commit code which breaks FFmpeg!
|
|
||||||
This means unfinished code which is enabled and breaks compilation,
|
|
||||||
or compiles but does not work/breaks the regression tests. Code which
|
|
||||||
is unfinished but disabled may be permitted under-circumstances, like
|
|
||||||
missing samples or an implementation with a small subset of features.
|
|
||||||
Always check the mailing list for any reviewers with issues and test
|
|
||||||
FATE before you push.
|
|
||||||
|
|
||||||
@subheading Keep the main commit message short with an extended description below.
|
|
||||||
The commit message should have a short first line in the form of
|
|
||||||
a @samp{topic: short description} as a header, separated by a newline
|
|
||||||
from the body consisting of an explanation of why the change is necessary.
|
|
||||||
If the commit fixes a known bug on the bug tracker, the commit message
|
|
||||||
should include its bug ID. Referring to the issue on the bug tracker does
|
|
||||||
not exempt you from writing an excerpt of the bug in the commit message.
|
|
||||||
|
|
||||||
@subheading Testing must be adequate but not excessive.
|
|
||||||
If it works for you, others, and passes FATE then it should be OK to commit
|
|
||||||
it, provided it fits the other committing criteria. You should not worry about
|
|
||||||
over-testing things. If your code has problems (portability, triggers
|
|
||||||
compiler bugs, unusual environment etc) they will be reported and eventually
|
|
||||||
fixed.
|
|
||||||
|
|
||||||
@subheading Do not commit unrelated changes together.
|
|
||||||
They should be split them into self-contained pieces. Also do not forget
|
|
||||||
that if part B depends on part A, but A does not depend on B, then A can
|
|
||||||
and should be committed first and separate from B. Keeping changes well
|
|
||||||
split into self-contained parts makes reviewing and understanding them on
|
|
||||||
the commit log mailing list easier. This also helps in case of debugging
|
|
||||||
later on.
|
|
||||||
Also if you have doubts about splitting or not splitting, do not hesitate to
|
|
||||||
ask/discuss it on the developer mailing list.
|
|
||||||
|
|
||||||
@subheading Ask before you change the build system (configure, etc).
|
|
||||||
Do not commit changes to the build system (Makefiles, configure script)
|
|
||||||
which change behavior, defaults etc, without asking first. The same
|
|
||||||
applies to compiler warning fixes, trivial looking fixes and to code
|
|
||||||
maintained by other developers. We usually have a reason for doing things
|
|
||||||
the way we do. Send your changes as patches to the ffmpeg-devel mailing
|
|
||||||
list, and if the code maintainers say OK, you may commit. This does not
|
|
||||||
apply to files you wrote and/or maintain.
|
|
||||||
|
|
||||||
@subheading Cosmetic changes should be kept in separate patches.
|
|
||||||
We refuse source indentation and other cosmetic changes if they are mixed
|
|
||||||
with functional changes, such commits will be rejected and removed. Every
|
|
||||||
developer has his own indentation style, you should not change it. Of course
|
|
||||||
if you (re)write something, you can use your own style, even though we would
|
|
||||||
prefer if the indentation throughout FFmpeg was consistent (Many projects
|
|
||||||
force a given indentation style - we do not.). If you really need to make
|
|
||||||
indentation changes (try to avoid this), separate them strictly from real
|
|
||||||
changes.
|
|
||||||
|
|
||||||
NOTE: If you had to put if()@{ .. @} over a large (> 5 lines) chunk of code,
|
|
||||||
then either do NOT change the indentation of the inner part within (do not
|
|
||||||
move it to the right)! or do so in a separate commit
|
|
||||||
|
|
||||||
@subheading Commit messages should always be filled out properly.
|
|
||||||
Always fill out the commit log message. Describe in a few lines what you
|
|
||||||
changed and why. You can refer to mailing list postings if you fix a
|
|
||||||
particular bug. Comments such as "fixed!" or "Changed it." are unacceptable.
|
|
||||||
Recommended format:
|
|
||||||
|
|
||||||
@example
|
|
||||||
area changed: Short 1 line description
|
|
||||||
|
|
||||||
details describing what and why and giving references.
|
|
||||||
@end example
|
|
||||||
|
|
||||||
@subheading Credit the author of the patch.
|
|
||||||
Make sure the author of the commit is set correctly. (see git commit --author)
|
|
||||||
If you apply a patch, send an
|
|
||||||
answer to ffmpeg-devel (or wherever you got the patch from) saying that
|
|
||||||
you applied the patch.
|
|
||||||
|
|
||||||
@subheading Complex patches should refer to discussion surrounding them.
|
|
||||||
When applying patches that have been discussed (at length) on the mailing
|
|
||||||
list, reference the thread in the log message.
|
|
||||||
|
|
||||||
@subheading Always wait long enough before pushing changes
|
|
||||||
Do NOT commit to code actively maintained by others without permission.
|
|
||||||
Send a patch to ffmpeg-devel. If no one answers within a reasonable
|
|
||||||
time-frame (12h for build failures and security fixes, 3 days small changes,
|
|
||||||
1 week for big patches) then commit your patch if you think it is OK.
|
|
||||||
Also note, the maintainer can simply ask for more time to review!
|
|
||||||
|
|
||||||
@subsection Code
|
|
||||||
@subheading API/ABI changes should be discussed before they are made.
|
|
||||||
Do not change behavior of the programs (renaming options etc) or public
|
|
||||||
API or ABI without first discussing it on the ffmpeg-devel mailing list.
|
|
||||||
Do not remove widely used functionality or features (redundant code can be removed).
|
|
||||||
|
|
||||||
@subheading Remember to check if you need to bump versions for libav*.
|
|
||||||
Depending on the change, you may need to change the version integer.
|
|
||||||
Incrementing the first component means no backward compatibility to
|
|
||||||
previous versions (e.g. removal of a function from the public API).
|
|
||||||
Incrementing the second component means backward compatible change
|
|
||||||
(e.g. addition of a function to the public API or extension of an
|
|
||||||
existing data structure).
|
|
||||||
Incrementing the third component means a noteworthy binary compatible
|
|
||||||
change (e.g. encoder bug fix that matters for the decoder). The third
|
|
||||||
component always starts at 100 to distinguish FFmpeg from Libav.
|
|
||||||
|
|
||||||
@subheading Warnings for correct code may be disabled if there is no other option.
|
|
||||||
Compiler warnings indicate potential bugs or code with bad style. If a type of
|
|
||||||
warning always points to correct and clean code, that warning should
|
|
||||||
be disabled, not the code changed.
|
|
||||||
Thus the remaining warnings can either be bugs or correct code.
|
|
||||||
If it is a bug, the bug has to be fixed. If it is not, the code should
|
|
||||||
be changed to not generate a warning unless that causes a slowdown
|
|
||||||
or obfuscates the code.
|
|
||||||
|
|
||||||
@subheading Check untrusted input properly.
|
|
||||||
Never write to unallocated memory, never write over the end of arrays,
|
|
||||||
always check values read from some untrusted source before using them
|
|
||||||
as array index or other risky things.
|
|
||||||
|
|
||||||
@subsection Documentation/Other
|
|
||||||
@subheading Subscribe to the ffmpeg-cvslog mailing list.
|
|
||||||
It is important to do this as the diffs of all commits are sent there and
|
|
||||||
reviewed by all the other developers. Bugs and possible improvements or
|
|
||||||
general questions regarding commits are discussed there. We expect you to
|
|
||||||
react if problems with your code are uncovered.
|
|
||||||
|
|
||||||
@subheading Keep the documentation up to date.
|
|
||||||
Update the documentation if you change behavior or add features. If you are
|
|
||||||
unsure how best to do this, send a patch to ffmpeg-devel, the documentation
|
|
||||||
maintainer(s) will review and commit your stuff.
|
|
||||||
|
|
||||||
@subheading Important discussions should be accessible to all.
|
|
||||||
Try to keep important discussions and requests (also) on the public
|
|
||||||
developer mailing list, so that all developers can benefit from them.
|
|
||||||
|
|
||||||
@subheading Check your entries in MAINTAINERS.
|
|
||||||
Make sure that no parts of the codebase that you maintain are missing from the
|
|
||||||
@file{MAINTAINERS} file. If something that you want to maintain is missing add it with
|
|
||||||
your name after it.
|
|
||||||
If at some point you no longer want to maintain some code, then please help in
|
|
||||||
finding a new maintainer and also don't forget to update the @file{MAINTAINERS} file.
|
|
||||||
|
|
||||||
We think our rules are not too hard. If you have comments, contact us.
|
|
||||||
|
|
||||||
@section Code of conduct
|
|
||||||
|
|
||||||
Be friendly and respectful towards others and third parties.
|
|
||||||
Treat others the way you yourself want to be treated.
|
|
||||||
|
|
||||||
Be considerate. Not everyone shares the same viewpoint and priorities as you do.
|
|
||||||
Different opinions and interpretations help the project.
|
|
||||||
Looking at issues from a different perspective assists development.
|
|
||||||
|
|
||||||
Do not assume malice for things that can be attributed to incompetence. Even if
|
|
||||||
it is malice, it's rarely good to start with that as initial assumption.
|
|
||||||
|
|
||||||
Stay friendly even if someone acts contrarily. Everyone has a bad day
|
|
||||||
once in a while.
|
|
||||||
If you yourself have a bad day or are angry then try to take a break and reply
|
|
||||||
once you are calm and without anger if you have to.
|
|
||||||
|
|
||||||
Try to help other team members and cooperate if you can.
|
|
||||||
|
|
||||||
The goal of software development is to create technical excellence, not for any
|
|
||||||
individual to be better and "win" against the others. Large software projects
|
|
||||||
are only possible and successful through teamwork.
|
|
||||||
|
|
||||||
If someone struggles do not put them down. Give them a helping hand
|
|
||||||
instead and point them in the right direction.
|
|
||||||
|
|
||||||
Finally, keep in mind the immortal words of Bill and Ted,
|
|
||||||
"Be excellent to each other."

||||||

|
||||||
@anchor{Submitting patches}
|
|
||||||
@section Submitting patches
|
|
||||||
|
|
||||||
First, read the @ref{Coding Rules} above if you did not yet, in particular
|
|
||||||
the rules regarding patch submission.
|
|
||||||
|
|
||||||
When you submit your patch, please use @code{git format-patch} or
|
|
||||||
@code{git send-email}. We cannot read other diffs :-).
|
|
||||||
|
|
||||||
Also please do not submit a patch which contains several unrelated changes.
|
|
||||||
Split it into separate, self-contained pieces. This does not mean splitting
|
|
||||||
file by file. Instead, make the patch as small as possible while still
|
|
||||||
keeping it as a logical unit that contains an individual change, even
|
|
||||||
if it spans multiple files. This makes reviewing your patches much easier
|
|
||||||
for us and greatly increases your chances of getting your patch applied.
|
|
||||||
|
|
||||||
Use the patcheck tool of FFmpeg to check your patch.
|
|
||||||
The tool is located in the tools directory.
|
|
||||||
|
|
||||||
Run the @ref{Regression tests} before submitting a patch in order to verify
|
|
||||||
it does not cause unexpected problems.
|
|
||||||
|
|
||||||
It also helps quite a bit if you tell us what the patch does (for example
|
|
||||||
'replaces lrint by lrintf'), and why (for example '*BSD isn't C99 compliant
|
|
||||||
and has no lrint()')
|
|
||||||
|
|
||||||
Also please if you send several patches, send each patch as a separate mail,
|
|
||||||
do not attach several unrelated patches to the same mail.
|
|
||||||
|
|
||||||
Patches should be posted to the
|
|
||||||
@uref{https://lists.ffmpeg.org/mailman/listinfo/ffmpeg-devel, ffmpeg-devel}
|
|
||||||
mailing list. Use @code{git send-email} when possible since it will properly
|
|
||||||
send patches without requiring extra care. If you cannot, then send patches
|
|
||||||
as base64-encoded attachments, so your patch is not trashed during
|
|
||||||
transmission. Also ensure the correct mime type is used
|
|
||||||
(text/x-diff or text/x-patch or at least text/plain) and that only one
|
|
||||||
patch is inline or attached per mail.
|
|
||||||
You can check @url{https://patchwork.ffmpeg.org}, if your patch does not show up, its mime type
|
|
||||||
likely was wrong.
|
|
||||||
|
|
||||||
Your patch will be reviewed on the mailing list. You will likely be asked
|
|
||||||
to make some changes and are expected to send in an improved version that
|
|
||||||
incorporates the requests from the review. This process may go through
|
|
||||||
several iterations. Once your patch is deemed good enough, some developer
|
|
||||||
will pick it up and commit it to the official FFmpeg tree.
|
|
||||||
|
|
||||||
Give us a few days to react. But if some time passes without reaction,
|
|
||||||
send a reminder by email. Your patch should eventually be dealt with.

@section Patch review process
|
|
||||||
|
|
||||||
All patches posted to ffmpeg-devel will be reviewed, unless they contain a
|
|
||||||
clear note that the patch is not for the git master branch.
|
|
||||||
Reviews and comments will be posted as replies to the patch on the
|
|
||||||
mailing list. The patch submitter then has to take care of every comment,
|
|
||||||
that can be by resubmitting a changed patch or by discussion. Resubmitted
|
|
||||||
patches will themselves be reviewed like any other patch. If at some point
|
|
||||||
a patch passes review with no comments then it is approved, that can for
|
|
||||||
simple and small patches happen immediately while large patches will generally
|
|
||||||
have to be changed and reviewed many times before they are approved.
|
|
||||||
After a patch is approved it will be committed to the repository.
|
|
||||||
|
|
||||||
We will review all submitted patches, but sometimes we are quite busy so
|
|
||||||
especially for large patches this can take several weeks.
|
|
||||||
|
|
||||||
If you feel that the review process is too slow and you are willing to try to
|
|
||||||
take over maintainership of the area of code you change then just clone
|
|
||||||
git master and maintain the area of code there. We will merge each area from
|
|
||||||
where its best maintained.
|
|
||||||
|
|
||||||
When resubmitting patches, please do not make any significant changes
|
|
||||||
not related to the comments received during review. Such patches will
|
|
||||||
be rejected. Instead, submit significant changes or new features as
|
|
||||||
separate patches.
|
|
||||||
|
|
||||||
Everyone is welcome to review patches. Also if you are waiting for your patch
|
|
||||||
to be reviewed, please consider helping to review other patches, that is a great
|
|
||||||
way to get everyone's patches reviewed sooner.
|
|
||||||
|
|
||||||
@anchor{Regression tests}
|
|
||||||
@section Regression tests
|
|
||||||
|
|
||||||
Before submitting a patch (or committing to the repository), you should at least
|
|
||||||
test that you did not break anything.
|
|
||||||
|
|
||||||
Running 'make fate' accomplishes this, please see @url{fate.html} for details.
|
|
||||||
|
|
||||||
[Of course, some patches may change the results of the regression tests. In
|
|
||||||
this case, the reference results of the regression tests shall be modified
|
|
||||||
accordingly].
|
|
||||||
|
|
||||||
@subsection Adding files to the fate-suite dataset
|
|
||||||
|
|
||||||
When there is no muxer or encoder available to generate test media for a
|
|
||||||
specific test then the media has to be included in the fate-suite.
|
|
||||||
First please make sure that the sample file is as small as possible to test the
|
|
||||||
respective decoder or demuxer sufficiently. Large files increase network
|
|
||||||
bandwidth and disk space requirements.
|
|
||||||
Once you have a working fate test and fate sample, provide in the commit
|
|
||||||
message or introductory message for the patch series that you post to
|
|
||||||
the ffmpeg-devel mailing list, a direct link to download the sample media.
|
|
||||||
|
|
||||||
@subsection Visualizing Test Coverage
|
|
||||||
|
|
||||||
The FFmpeg build system allows visualizing the test coverage in an easy
|
|
||||||
manner with the coverage tools @code{gcov}/@code{lcov}. This involves
|
|
||||||
the following steps:
|
|
||||||
|
|
||||||
@enumerate
|
|
||||||
@item
|
|
||||||
Configure to compile with instrumentation enabled:
|
|
||||||
@code{configure --toolchain=gcov}.
|
|
||||||
|
|
||||||
@item
|
|
||||||
Run your test case, either manually or via FATE. This can be either
|
|
||||||
the full FATE regression suite, or any arbitrary invocation of any
|
|
||||||
front-end tool provided by FFmpeg, in any combination.
|
|
||||||
|
|
||||||
@item
|
|
||||||
Run @code{make lcov} to generate coverage data in HTML format.
|
|
||||||
|
|
||||||
@item
|
|
||||||
View @code{lcov/index.html} in your preferred HTML viewer.
|
|
||||||
@end enumerate
|
|
||||||

|
||||||
You can use the command @code{make lcov-reset} to reset the coverage
|
|
||||||
measurements. You will need to rerun @code{make lcov} after running a
|
|
||||||
new test.
|
|
||||||
|
|
||||||
@subsection Using Valgrind
|
|
||||||
|
|
||||||
The configure script provides a shortcut for using valgrind to spot bugs
|
|
||||||
related to memory handling. Just add the option
|
|
||||||
@code{--toolchain=valgrind-memcheck} or @code{--toolchain=valgrind-massif}
|
|
||||||
to your configure line, and reasonable defaults will be set for running
|
|
||||||
FATE under the supervision of either the @strong{memcheck} or the
|
|
||||||
@strong{massif} tool of the valgrind suite.
|
|
||||||
|
|
||||||
In case you need finer control over how valgrind is invoked, use the
|
|
||||||
@code{--target-exec='valgrind <your_custom_valgrind_options>} option in
|
|
||||||
your configure line instead.

|
|

@section Release process
|
|
||||||
|
|
||||||
FFmpeg maintains a set of @strong{release branches}, which are the
|
|
||||||
recommended deliverable for system integrators and distributors (such as
|
|
||||||
Linux distributions, etc.). At regular times, a @strong{release
|
|
||||||
manager} prepares, tests and publishes tarballs on the
|
|
||||||
@url{https://ffmpeg.org} website.
|
|
||||||
|
|
||||||
There are two kinds of releases:
|
|
||||||
|
|
||||||
@enumerate
|
|
||||||
@item
|
|
||||||
@strong{Major releases} always include the latest and greatest
|
|
||||||
features and functionality.
|
|
||||||
|
|
||||||
@item
|
|
||||||
@strong{Point releases} are cut from @strong{release} branches,
|
|
||||||
which are named @code{release/X}, with @code{X} being the release
|
|
||||||
version number.
|
|
||||||
@end enumerate
|
|
||||||
|
|
||||||
Note that we promise to our users that shared libraries from any FFmpeg
|
|
||||||
release never break programs that have been @strong{compiled} against
|
|
||||||
previous versions of @strong{the same release series} in any case!
|
|
||||||
|
|
||||||
However, from time to time, we do make API changes that require adaptations
|
|
||||||
in applications. Such changes are only allowed in (new) major releases and
|
|
||||||
require further steps such as bumping library version numbers and/or
|
|
||||||
adjustments to the symbol versioning file. Please discuss such changes
|
|
||||||
on the @strong{ffmpeg-devel} mailing list in time to allow forward planning.
|
|
||||||
|
|
||||||
@anchor{Criteria for Point Releases}
|
|
||||||
@subsection Criteria for Point Releases
|
|
||||||
|
|
||||||
Changes that match the following criteria are valid candidates for
|
|
||||||
inclusion into a point release:
|
|
||||||
|
|
||||||
@enumerate
|
|
||||||
@item
|
|
||||||
Fixes a security issue, preferably identified by a @strong{CVE
|
|
||||||
number} issued by @url{http://cve.mitre.org/}.
|
|
||||||
|
|
||||||
@item
|
|
||||||
Fixes a documented bug in @url{https://trac.ffmpeg.org}.
|
|
||||||
|
|
||||||
@item
|
|
||||||
Improves the included documentation.
|
|
||||||
|
|
||||||
@item
|
|
||||||
Retains both source code and binary compatibility with previous
|
|
||||||
point releases of the same release branch.
|
|
||||||
@end enumerate
|
|
||||||
|
|
||||||
The order for checking the rules is (1 OR 2 OR 3) AND 4.
|
|
||||||
|
|
||||||
|
|
||||||
@subsection Release Checklist
|
|
||||||
|
|
||||||
The release process involves the following steps:
|
|
||||||
|
|
||||||
@enumerate
|
|
||||||
@item
|
|
||||||
Ensure that the @file{RELEASE} file contains the version number for
|
|
||||||
the upcoming release.
|
|
||||||
|
|
||||||
@item
|
|
||||||
Add the release at @url{https://trac.ffmpeg.org/admin/ticket/versions}.
|
|
||||||
|
|
||||||
@item
|
|
||||||
Announce the intent to do a release to the mailing list.
|
|
||||||
|
|
||||||
@item
|
|
||||||
Make sure all relevant security fixes have been backported. See
|
|
||||||
@url{https://ffmpeg.org/security.html}.
|
|
||||||
|
|
||||||
@item
|
|
||||||
Ensure that the FATE regression suite still passes in the release
|
|
||||||
branch on at least @strong{i386} and @strong{amd64}
|
|
||||||
(cf. @ref{Regression tests}).
|
|
||||||
|
|
||||||
@item
|
|
||||||
Prepare the release tarballs in @code{bz2} and @code{gz} formats, and
|
|
||||||
supplementing files that contain @code{gpg} signatures
|
|
||||||
|
|
||||||
@item
|
|
||||||
Publish the tarballs at @url{https://ffmpeg.org/releases}. Create and
|
|
||||||
push an annotated tag in the form @code{nX}, with @code{X}
|
|
||||||
containing the version number.
|
|
||||||
|
|
||||||
@item
|
|
||||||
Propose and send a patch to the @strong{ffmpeg-devel} mailing list
|
|
||||||
with a news entry for the website.
|
|
||||||
|
|
||||||
@item
|

@c man begin DEVICE OPTIONS
|
|
||||||
|
|
||||||
The libavdevice library provides the same interface as
|
|
||||||
libavformat. Namely, an input device is considered like a demuxer, and
|
|
||||||
an output device like a muxer, and the interface and generic device
|
|
||||||
options are the same provided by libavformat (see the ffmpeg-formats
|
|
||||||
manual).
|
|
||||||
|
|
||||||
In addition each input or output device may support so-called private
|
|
||||||
options, which are specific for that component.
|
|
||||||
|
|
||||||
Options may be set by specifying -@var{option} @var{value} in the
|
|
||||||
FFmpeg tools, or by setting the value explicitly in the device
|
|
||||||
@code{AVFormatContext} options or using the @file{libavutil/opt.h} API
|

for programmatic use.

FFmpeg examples README
|
|
||||||
----------------------
|
|
||||||
|
|
||||||
Both following use cases rely on pkg-config and make, thus make sure
|
|
||||||
that you have them installed and working on your system.
|
|
||||||
|
|
||||||
|
|
||||||
Method 1: build the installed examples in a generic read/write user directory
|
|
||||||
|
|
||||||
Copy to a read/write user directory and just use "make", it will link
|
|
||||||
to the libraries on your system, assuming the PKG_CONFIG_PATH is
|
|
||||||
correctly configured.
|
|
||||||
|
|
||||||
Method 2: build the examples in-tree
|
|
||||||
|
|
||||||
Assuming you are in the source FFmpeg checkout directory, you need to build
|
|
||||||
FFmpeg (no need to make install in any prefix). Then just run "make examples".
|
|
||||||
This will build the examples using the FFmpeg build system. You can clean those
|
|
||||||
examples using "make examplesclean"
|
|
||||||
|
|
||||||
If you want to try the dedicated Makefile examples (to emulate the first
|
|
||||||
method), go into doc/examples and run a command such as
|
|
||||||
PKG_CONFIG_PATH=pc-uninstalled make.

* @file

* libavfilter API usage example.
|
|

*
|
|

* @example filter_audio.c
|
|

* This example will generate a sine wave audio,

||||||
* the output data.
|
|

*
|

* The filter chain it uses is:
|
|
||||||
* (input) -> abuffer -> volume -> aformat -> abuffersink -> (output)
|
|
||||||
*
|
|
||||||
* abuffer: This provides the endpoint where you can feed the decoded samples.
|
|
||||||
* volume: In this example we hardcode it to 0.90.
|
|
||||||
* aformat: This converts the samples to the samplefreq, channel layout,
|
|
||||||
* and sample format required by the audio device.
|
|
||||||
* abuffersink: This provides the endpoint where you can read the samples after
|
|
||||||
* they have passed through the filter chain.
