configure: fix symver detection with icc 10

Apparently the compiler sometimes bypasses the normal assembler, in
which case the asm label variant works.  If the file contains any
inline asm, this bypassing is not done, and the assembler chokes on
invalid syntax.  Inserting a dummy asm() statement in the test when
the compiler supports it makes sure no shortcuts are taken and the
test fails as it should.

 Release Notes
 =============
 
-* 0.5 "Bike Shed World Domination" March 3, 2009
+* 0.6 "Works with HTML5" June, 2010
 
 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.
+This release features a lot of improvements that are relevant for HTML5 video.
+The H.264 and Theora decoders are now significantly faster, the vorbis decoder
+has seen important updates and this release supports Google's newly released
+libvpx library for the VP8 codec and WEBM container.
+
+Other important changes are additions of decoders including, but not limited to,
+Intel Indeo 5, WMA Pro, WMA Voice and HE-AAC.
 
 See the Changelog file for a list of significant changes.

-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.
+API and other notable Changes
+-----------------------------
 
-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
+Please see the file doc/APIchanges for programmer-centric information.
 
-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.
+Notable changes:
+- deprecated vhook subsystem removed
+- deprecated old scaler removed
+- nonfree libamr support for AMR-NB/WB decoding/encoding removed
+- RTMP support in libavformat
+- -formats option split into -formats, -codecs, -bsfs, and -protocols
+- ffprobe tool
+- RTMP/RTMPT/RTMPS/RTMPE/RTMPTE protocol support via librtmp
+- CODEC_CAP_EXPERIMENTAL added

-* 0.5.1 March 2, 2010
-
-General notes
+Added Codecs:
 -------------
 
-This point release includes some minor updates to make the 0.5 release series
-usable for users that need to retain the existing behavior as closely as
-possible. The changes follow below:
-
-Security fixes
---------------
-
-Various programming errors in container and codec implementations
-may lead to denial of service or the execution of arbitrary code
-if the user is tricked into opening a malformed media file or stream.
-
-Affected and updated have been the implementations of the following
-codecs and container formats:
-
- - the Vorbis audio codec
- - the FF Video 1 codec
- - the MPEG audio codec
- - the H264 video codec
- - the MLP codec
- - the HuffYUV codec
- - the ASF demuxer
- - the Ogg container implementation
- - the MOV container implementation
-
-Symbol Versioning enabled
--------------------------
-
-The backported symbol versioning change is enabled on platforms that support
-it. This allows users to upgrade from 0.5.1 to the upcoming 0.6 release
-without having to recompile their applications. Please note that distributors
-have to recompile applications against 0.5.1 before upgrading to 0.6.
-
-libx264.c backport
-------------------
-
-This release includes a backport to the libx264 wrapper that allows FFmpeg to
-be compiled against newer versions of libx264 up to API version 85.
-
-licensing changes
------------------
-
-Previously both libswscale and our AC-3 decoder had GPLed parts. These have
-been replaced by fresh LGPL code. x86 optimizations for libswscale remain GPL,
-but the C code is fully functional. Optimizations for other architectures have
-been relicensed to LGPL.
-
-AMR-NB decoding/encoding and AMR-WB decoding is now possible through the free
-software OpenCORE libraries as an alternative to the non-free libamr libraries.
-
-We found out that libfaac contains non-free parts and is not LGPL as previously
-claimed. We have changed configure to reflect this. You now have to pass the
---enable-nonfree option if you wish to compile with libfaac support enabled.
-
-Furthermore the non-free bits in libavcodec/fdctref.c have been rewritten. Note
-well that they were only used in a test program and never compiled into any
-FFmpeg library.

-20090301 - r17682 - lavf 52.31.0 - Generic metadata API
-  This version introduce a new metadata API (see av_metadata_get() and friends).
-  The old API is now deprecated and shouldn't be used anymore. This especially
-  include the following structure fields:
+2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet
+  av_free_packet() is no longer an inline function. It is now exported.
+
+2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree
+  Please use NULL instead. This has been supported since r16506
+  (lavf > 52.23.1, lavc > 52.10.0).
+
+2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
+  The old decoding functions are deprecated, all new code should use the
+  new functions avcodec_decode_video2(), avcodec_decode_audio3() and
+  avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
+  argument instead of a const uint8_t *buf / int buf_size pair.
+
+2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space
+  Introduce the av_fifo_space() function.
+
+2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
+  Move AVPacket declaration from libavformat/avformat.h to
+  libavcodec/avcodec.h.
+
+2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
+  Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
+  PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
+  Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
+  PIX_FMT_BGR32_1 are now macros.
+  avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
+  Re-sort the enum PixelFormat list accordingly.
+  This change breaks API/ABI backward compatibility.
+
+2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
+  Add the enum PixelFormat values:
+  PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
+  PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
+
+2009-03-21 - r18116 - lavu 50.0.0  - av_random*
+  The Mersenne Twister PRNG implemented through the av_random* functions
+  was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
+  instead.
+
+2009-03-08 - r17869 - lavu 50.0.0  - AVFifoBuffer
+  av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
+  and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
+  and av_fifo_realloc2.
+  In addition, the order of the function arguments of av_fifo_generic_read
+  was changed to match av_fifo_generic_write.
+  The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
+  applications, they may not use sizeof() or directly access members.
+
+2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
+  Introduce a new metadata API (see av_metadata_get() and friends).
+  The old API is now deprecated and should not be used anymore. This especially

+@itemize @bullet
+@item libavcodec is the library containing the codecs (both encoding and
+decoding). Look at @file{libavcodec/apiexample.c} to see how to use it.
+

+audio or video streams.
+
+@end itemize
+
+@section Integrating libavcodec or libavformat in your program
+
+You can integrate all the source code of the libraries to link them
+statically to avoid any version problem. All you need is to provide a
+'config.mak' and a 'config.h' in the parent directory. See the defines
+generated by ./configure to understand what is needed.
+
+You can use libavcodec or libavformat in your commercial program, but
+@emph{any patch you make must be published}. The best way to proceed is
+to send your patches to the FFmpeg mailing list.
+
+@anchor{Coding Rules}
+@section Coding Rules
+
+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 @};})
+@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 GCC 2.95 and GCC 3.3. Currently, FFmpeg also
+compiles with several other compilers, such as the Compaq ccc compiler
+or Sun Studio 9, and we would like to keep it that way unless it would
+be exceedingly involved. To ensure compatibility, please do not use any
+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
+
+Indent size is 4.
+The presentation is one inspired by 'indent -i4 -kr -nut'.
+The TAB character is forbidden outside of Makefiles as is any
+form of trailing whitespace. Commits containing either will be
+rejected by the Subversion repository.
+
+The main priority in FFmpeg is simplicity and small code size in order to
+minimize the bug count.
+
+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.
+@example
+/**
+ * @@file mpeg.c
+ * MPEG codec.
+ * @@author ...
+ */
+
+/**
+ * Summary sentence.
+ * more text ...
+ * ...
+ */
+typedef struct Foobar@{
+    int var1; /**< var1 description */
+    int var2; ///< var2 description
+    /** var3 description */
+    int var3;
+@} Foobar;
+
+/**
+ * Summary sentence.
+ * more text ...
+ * ...
+ * @@param my_parameter description of my_parameter
+ * @@return return value description
+ */
+int myfunc(int my_parameter)
+...
+@end example
+
+fprintf and printf are forbidden in libavformat and libavcodec,
+please use av_log() instead.
+
+Casts should be used only when necessary. Unneeded parentheses
+should also be avoided if they don't make the code easier to understand.
+
+@section Development Policy
+
+@enumerate
+@item
+   Contributions should be licensed under the LGPL 2.1, including an
+   "or any later version" clause, or the MIT license.  GPL 2 including
+   an "or any later version" clause is also acceptable, but LGPL is
+   preferred.
+@item
+   You must not commit code which breaks FFmpeg! (Meaning unfinished but
+   enabled code which breaks compilation or compiles but does not work or
+   breaks the regression tests)
+   You can commit unfinished stuff (for testing etc), but it must be disabled
+   (#ifdef etc) by default so it does not interfere with other developers'
+   work.
+@item
+   You do not have to over-test things. If it works for you, and you think it
+   should work for others, then commit. If your code has problems
+   (portability, triggers compiler bugs, unusual environment etc) they will be
+   reported and eventually fixed.
+@item
+   Do not commit unrelated changes together, 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.
+@item
+   Do not change behavior of the program (renaming options etc) without
+   first discussing it on the ffmpeg-devel mailing list. Do not remove
+   functionality from the code. Just improve!
+
+   Note: Redundant code can be removed.
+@item
+   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.
+@item
+   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
+@item
+   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.
+@item
+   If you apply a patch by someone else, include the name and email address in
+   the log message. Since the ffmpeg-cvslog mailing list is publicly
+   archived you should add some SPAM protection to the email address. Send an
+   answer to ffmpeg-devel (or wherever you got the patch from) saying that
+   you applied the patch.
+@item
+   When applying patches that have been discussed (at length) on the mailing
+   list, reference the thread in the log message.
+@item
+    Do NOT commit to code actively maintained by others without permission.
+    Send a patch to ffmpeg-devel instead. If no one answers within a reasonable
+    timeframe (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!
+@item
+    Subscribe to the ffmpeg-cvslog mailing list. 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.
+@item
+    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.
+@item
+    Try to keep important discussions and requests (also) on the public

+
+@section Submitting patches
+
+First, (@pxref{Coding Rules}) above if you did not yet.
+
+When you submit your patch, try to send a unified diff (diff '-up'
+option). 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 regression tests before submitting a patch so that you can
+verify that there are no big problems.
+
+Patches should be posted as base64 encoded attachments (or any other
+encoding which ensures that the patch will not be trashed during
+transmission) to the ffmpeg-devel mailing list, see
+@url{http://lists.mplayerhq.hu/mailman/listinfo/ffmpeg-devel}
+
+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.
+
+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.

+@item
+    Did you test your decoder or demuxer against damaged data? If no, see

+@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 SVN.
+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.
+
+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.
+
+@section Regression tests
+
+Before submitting a patch (or committing to the repository), you should at least
+test that you did not break anything.
+
+The regression tests build a synthetic video stream and a synthetic
+audio stream. These are then encoded and decoded with all codecs or
+formats. The CRC (or MD5) of each generated file is recorded in a
+result file. A 'diff' is launched to compare the reference results and
+the result file. The output is checked immediately after each test
+has run.
+
+The regression tests then go on to test the FFserver code with a
+limited set of streams. It is important that this step runs correctly
+as well.
+
+Run 'make test' to test all the codecs and formats. Commands like
+'make regtest-mpeg2' can be used to run a single test. By default,
+make will abort if any test fails. To run all tests regardless,
+use make -k. To get a more verbose output, use 'make V=1 test' or
+'make V=2 test'.
+
+Run 'make fulltest' to test all the codecs, formats and FFserver.
+
+[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].

+@chapter Introduction
+
+@c man begin DESCRIPTION
+
+FFprobe gathers information from multimedia streams and prints it in
+human- and machine-readable fashion.
+
+For example it can be used to check the format of the container used
+by a multimedia stream and the format and type of each media stream
+contained in it.
+
+If a filename is specified in input, ffprobe will try to open and
+probe the file content. If the file cannot be opened or recognized as
+a multimedia file, a positive exit code is returned.
+
+FFprobe may be employed both as a standalone application or in
+combination with a textual filter, which may perform more
+sophisticated processing, e.g. statistical processing or plotting.
+
+Options are used to list some of the formats supported by ffprobe or
+for specifying which information to display, and for setting how
+ffprobe will show it.
+
+FFprobe output is designed to be easily parsable by a textual filter,
+and consists of one or more sections of the form:
+@example
+[SECTION]
+key1=val1
+...
+keyN=valN
+[/SECTION]
+@end example
+
+Metadata tags stored in the container or in the streams are recognized
+and printed in the corresponding ``FORMAT'' or ``STREAM'' section, and
+are prefixed by the string ``TAG:''.

+workaround.

+
+@section Unix-like
+
+Some parts of FFmpeg cannot be built with version 2.15 of the GNU
+assembler which is still provided by a few AMD64 distributions. To
+make sure your compiler really uses the required version of gas
+after a binutils upgrade, run:
+
+@example
+$(gcc -print-prog-name=as) --version
+@end example
+
+If not, then you should install a different compiler that has no
+hard-coded path to gas. In the worst case pass @code{--disable-asm}
+to configure.
+
+@subsection BSD
 
 BSD make will not build FFmpeg, you need to install and use GNU Make
 (@file{gmake}).
 
+@subsubsection FreeBSD
+
+FreeBSD will not compile out-of-the-box due to broken system headers.
+Passing @code{--extra-cflags=-D__BSD_VISIBLE} to configure will work
+around the problem. This may have unexpected sideeffects, so use it at
+your own risk. If you care about FreeBSD, please make an attempt at
+getting the system headers fixed.
+
+@subsection (Open)Solaris
+
+GNU Make is required to build FFmpeg, so you have to invoke (@file{gmake}),
+standard Solaris Make will not work. When building with a non-c99 front-end
+(gcc, generic suncc) add either @code{--extra-libs=/usr/lib/values-xpg6.o}
+or @code{--extra-libs=/usr/lib/64/values-xpg6.o} to the configure options
+since the libc is not c99-compliant by default. The probes performed by
+configure may raise an exception leading to the death of configure itself
+due to a bug in the system shell. Simply invoke a different shell such as
+bash directly to work around this:

-@item libavcodec is the library containing the codecs (both encoding and
-decoding). Look at @file{libavcodec/apiexample.c} to see how to use it.
-

-@section Integrating libavcodec or libavformat in your program
-
-You can integrate all the source code of the libraries to link them
-statically to avoid any version problem. All you need is to provide a
-'config.mak' and a 'config.h' in the parent directory. See the defines
-generated by ./configure to understand what is needed.

-
-@node Coding Rules
-@section Coding Rules
-
-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 @};})
-@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 GCC 2.95 and GCC 3.3. Currently, FFmpeg also
-compiles with several other compilers, such as the Compaq ccc compiler
-or Sun Studio 9, and we would like to keep it that way unless it would
-be exceedingly involved. To ensure compatibility, please do not use any
-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
-
-Indent size is 4.
-The presentation is the one specified by 'indent -i4 -kr -nut'.
-The TAB character is forbidden outside of Makefiles as is any
-form of trailing whitespace. Commits containing either will be
-rejected by the Subversion repository.
-
-The main priority in FFmpeg is simplicity and small code size in order to
-minimize the bug count.
-
-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.

-@end example
-
-fprintf and printf are forbidden in libavformat and libavcodec,
-please use av_log() instead.

-Casts should be used only when necessary. Unneeded parentheses
-should also be avoided if they don't make the code easier to understand.

-@section Development Policy
-
-@enumerate
-@item
-   Contributions should be licensed under the LGPL 2.1, including an
-   "or any later version" clause, or the MIT license.  GPL 2 including
-   an "or any later version" clause is also acceptable, but LGPL is
-   preferred.
-@item
-   You must not commit code which breaks FFmpeg! (Meaning unfinished but
-   enabled code which breaks compilation or compiles but does not work or
-   breaks the regression tests)
-   You can commit unfinished stuff (for testing etc), but it must be disabled
-   (#ifdef etc) by default so it does not interfere with other developers'
-   work.
-@item
-   You do not have to over-test things. If it works for you, and you think it
-   should work for others, then commit. If your code has problems
-   (portability, triggers compiler bugs, unusual environment etc) they will be
-   reported and eventually fixed.
-@item
-   Do not commit unrelated changes together, 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.
-@item
-   Do not change behavior of the program (renaming options etc) without
-   first discussing it on the ffmpeg-devel mailing list. Do not remove
-   functionality from the code. Just improve!
-
-   Note: Redundant code can be removed.
-@item
-   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.
-@item
-   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
-@item
-   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.
-@item
-   If you apply a patch by someone else, include the name and email address in
-   the log message. Since the ffmpeg-cvslog mailing list is publicly
-   archived you should add some SPAM protection to the email address. Send an
-   answer to ffmpeg-devel (or wherever you got the patch from) saying that
-   you applied the patch.
-@item
-   When applying patches that have been discussed (at length) on the mailing
-   list, reference the thread in the log message.
-@item
-    Do NOT commit to code actively maintained by others without permission.
-    Send a patch to ffmpeg-devel instead. If no one answers within a reasonable
-    timeframe (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!
-@item
-    Subscribe to the ffmpeg-cvslog mailing list. 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.
-@item
-    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.
-@item
-    Try to keep important discussions and requests (also) on the public
-    developer mailing list, so that all developers can benefit from them.
-@item
-    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.
-@item
-    Remember to check if you need to bump versions for the specific libav
-    parts (libavutil, libavcodec, libavformat) you are changing. You 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).
-@item
-    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.
-@item
-    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.
-@end enumerate
-
-We think our rules are not too hard. If you have comments, contact us.
-
-Note, these rules are mostly borrowed from the MPlayer project.
-
-@section Submitting patches
-
-First, (@pxref{Coding Rules}) above if you did not yet.
-
-When you submit your patch, try to send a unified diff (diff '-up'
-option). 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.
-
-Run the regression tests before submitting a patch so that you can
-verify that there are no big problems.
-
-Patches should be posted as base64 encoded attachments (or any other
-encoding which ensures that the patch will not be trashed during
-transmission) to the ffmpeg-devel mailing list, see
-@url{http://lists.mplayerhq.hu/mailman/listinfo/ffmpeg-devel}
-
-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.

-    Did you add tabs or trailing whitespace to the code? Both are forbidden.
-@item
-    Is the patch attached to the email you send?

-
-@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 SVN.
-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.
-
-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.
-
-@section Regression tests
-
-Before submitting a patch (or committing to the repository), you should at least
-test that you did not break anything.
-
-The regression tests build a synthetic video stream and a synthetic
-audio stream. These are then encoded and decoded with all codecs or
-formats. The CRC (or MD5) of each generated file is recorded in a
-result file. A 'diff' is launched to compare the reference results and
-the result file.
-
-The regression tests then go on to test the FFserver code with a
-limited set of streams. It is important that this step runs correctly
-as well.
-
-Run 'make test' to test all the codecs and formats.
-
-Run 'make fulltest' to test all the codecs, formats and FFserver.
-
-[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].

-
-@chapter Introduction
-
-@var{Please be aware that vhook is deprecated, and hence its development is
-frozen (bug fixes are still accepted).
-The substitute will be 'libavfilter', the result of our 'Video Filter API'
-Google Summer of Code project. You may monitor its progress by subscribing to
-the ffmpeg-soc mailing list at
-@url{http://lists.mplayerhq.hu/mailman/listinfo/ffmpeg-soc}.}
-
-The video hook functionality is designed (mostly) for live video. It allows
-the video to be modified or examined between the decoder and the encoder.
-
-Any number of hook modules can be placed inline, and they are run in the
-order that they were specified on the ffmpeg command line.
-
-The video hook modules are provided for use as a base for your own modules,
-and are described below.
-
-Modules are loaded using the -vhook option to ffmpeg. The value of this parameter
-is a space separated list of arguments. The first is the module name, and the rest
-are passed as arguments to the Configure function of the module.
-
-The modules are dynamic libraries: They have different suffixes (.so, .dll, .dylib)
-depending on your platform. And your platform dictates if they need to be
-somewhere in your PATH, or in your LD_LIBRARY_PATH. Otherwise you will need to
-specify the full path of the vhook file that you are using.
-
-@section null.c
-
-This does nothing. Actually it converts the input image to RGB24 and then converts
-it back again. This is meant as a sample that you can use to test your setup.
-
-@section fish.c
-
-This implements a 'fish detector'. Essentially it converts the image into HSV
-space and tests whether more than a certain percentage of the pixels fall into
-a specific HSV cuboid. If so, then the image is saved into a file for processing
-by other bits of code.
-
-Why use HSV? It turns out that HSV cuboids represent a more compact range of
-colors than would an RGB cuboid.
-
-@section imlib2.c
-
-This module implements a text overlay for a video image. Currently it
-supports a fixed overlay or reading the text from a file. The string
-is passed through strftime() so that it is easy to imprint the date and
-time onto the image.
-
-This module depends on the external library imlib2, available on
-Sourceforge, among other places, if it is not already installed on
-your system.
-
-You may also overlay an image (even semi-transparent) like TV stations do.
-You may move either the text or the image around your video to create
-scrolling credits, for example.
-
-The font file used is looked for in a FONTPATH environment variable, and
-prepended to the point size as a command line option and can be specified
-with the full path to the font file, as in:
-@example
--F /usr/X11R6/lib/X11/fonts/TTF/VeraBd.ttf/20
-@end example
-where 20 is the point size.
-
-You can specify the filename to read RGB color names from. If it is not
-specified, these defaults are used: @file{/usr/share/X11/rgb.txt} and
-@file{/usr/lib/X11/rgb.txt}
-
-Options:
-@multitable @columnfractions .2 .8
-@item @option{-C <rgb.txt>}   @tab The filename to read RGB color names from
-@item @option{-c <color>}     @tab The color of the text
-@item @option{-F <fontname>}  @tab The font face and size
-@item @option{-t <text>}      @tab The text
-@item @option{-f <filename>}  @tab The filename to read text from
-@item @option{-x <expression>}@tab x coordinate of text or image
-@item @option{-y <expression>}@tab y coordinate of text or image
-@item @option{-i <filename>}  @tab The filename to read a image from
-@item @option{-R <expression>}@tab Value for R color
-@item @option{-G <expression>}@tab Value for G color
-@item @option{-B <expression>}@tab Value for B color
-@item @option{-A <expression>}@tab Value for Alpha channel
-@end multitable
-
-Expressions are functions of these variables:
-@multitable @columnfractions .2 .8
-@item @var{N} @tab frame number (starting at zero)
-@item @var{H} @tab frame height
-@item @var{W} @tab frame width
-@item @var{h} @tab image height
-@item @var{w} @tab image width
-@item @var{X} @tab previous x coordinate of text or image
-@item @var{Y} @tab previous y coordinate of text or image
-@end multitable
-
-You may also use the constants @var{PI}, @var{E}, and the math functions available at the
-FFmpeg formula evaluator at (@url{ffmpeg-doc.html#SEC13}), except @var{bits2qp(bits)}
-and @var{qp2bits(qp)}.
-
-Usage examples:
-
-@example
-   # Remember to set the path to your fonts
-   FONTPATH="/cygdrive/c/WINDOWS/Fonts/"
-   FONTPATH="$FONTPATH:/usr/share/imlib2/data/fonts/"
-   FONTPATH="$FONTPATH:/usr/X11R6/lib/X11/fonts/TTF/"
-   export FONTPATH
-
-   # Bulb dancing in a Lissajous pattern
-   ffmpeg -i input.avi -vhook \
-     'vhook/imlib2.dll -x W*(0.5+0.25*sin(N/47*PI))-w/2 -y H*(0.5+0.50*cos(N/97*PI))-h/2 -i /usr/share/imlib2/data/images/bulb.png' \
-     -acodec copy -sameq output.avi
-
-   # Text scrolling
-   ffmpeg -i input.avi -vhook \
-     'vhook/imlib2.dll -c red -F Vera.ttf/20 -x 150+0.5*N -y 70+0.25*N -t Hello' \
-     -acodec copy -sameq output.avi
-
-   # Date and time stamp, security-camera style:
-   ffmpeg -r 29.97 -s 320x256 -f video4linux -i /dev/video0 \
-     -vhook 'vhook/imlib2.so -x 0 -y 0 -i black-260x20.png' \
-     -vhook 'vhook/imlib2.so -c white -F VeraBd.ttf/12 -x 0 -y 0 -t %A-%D-%T' \
-     output.avi
-
-     In this example the video is captured from the first video capture card as a
-     320x256 AVI, and a black 260 by 20 pixel PNG image is placed in the upper
-     left corner, with the day, date and time overlaid on it in Vera Bold 12
-     point font. A simple black PNG file 260 pixels wide and 20 pixels tall
-     was created in the GIMP for this purpose.
-
-   # Scrolling credits from a text file
-   ffmpeg -i input.avi -vhook \
-     'vhook/imlib2.so -c white -F VeraBd.ttf/16 -x 100 -y -1.0*N -f credits.txt' \
-     -sameq output.avi
-
-     In this example, the text is stored in a file, and is positioned 100
-     pixels from the left hand edge of the video. The text is scrolled from the
-     bottom up. Making the y factor positive will scroll from the top down.
-     Increasing the magnitude of the y factor makes the text scroll faster,
-     decreasing it makes it scroll slower. Hint: Blank lines containing only
-     a newline are treated as end-of-file. To create blank lines, use lines
-     that consist of space characters only.
-
-   # Scrolling credits with custom color from a text file
-   ffmpeg -i input.avi -vhook \
-     'vhook/imlib2.so -C rgb.txt -c CustomColor1 -F VeraBd.ttf/16 -x 100 -y -1.0*N -f credits.txt' \
-     -sameq output.avi
-
-     This example does the same as the one above, but specifies an rgb.txt file
-     to be used, which has a custom-made color in it.
-
-   # Variable colors
-   ffmpeg -i input.avi -vhook \
-     'vhook/imlib2.so -t Hello -R abs(255*sin(N/47*PI)) -G abs(255*sin(N/47*PI)) -B abs(255*sin(N/47*PI))' \
-     -sameq output.avi
-
-     In this example, the color for the text goes up and down from black to
-     white.
-
-   # Text fade-out
-   ffmpeg -i input.avi -vhook \
-     'vhook/imlib2.so -t Hello -A max(0,255-exp(N/47))' \
-     -sameq output.avi
-
-     In this example, the text fades out in about 10 seconds for a 25 fps input
-     video file.
-
-   # scrolling credits from a graphics file
-   ffmpeg -sameq -i input.avi \
-     -vhook 'vhook/imlib2.so -x 0 -y -1.0*N -i credits.png' output.avi
-
-     In this example, a transparent PNG file the same width as the video
-     (e.g. 320 pixels), but very long, (e.g. 3000 pixels), was created, and
-     text, graphics, brushstrokes, etc, were added to the image. The image
-     is then scrolled up, from the bottom of the frame.
-
-@end example
-
-@section ppm.c
-
-It's basically a launch point for a PPM pipe, so you can use any
-executable (or script) which consumes a PPM on stdin and produces a PPM
-on stdout (and flushes each frame). The Netpbm utilities are a series of
-such programs.
-
-A list of them is here:
-
-@url{http://netpbm.sourceforge.net/doc/directory.html}

-@example
-ffmpeg -i input -vhook "/path/to/ppm.so some-ppm-filter args" output
-@end example
-
-@section drawtext.c
-
-This module implements a text overlay for a video image. Currently it
-supports a fixed overlay or reading the text from a file. The string
-is passed through strftime() so that it is easy to imprint the date and
-time onto the image.
-
-Features:
-@itemize @minus
-@item TrueType, Type1 and others via the FreeType2 library
-@item Font kerning (better output)
-@item Line Wrap (put the text that doesn't fit one line on the next line)

-@item @option{-y <pos>}            @tab y coordinate of the start of the text
-@end multitable
-
-Text fonts are being looked for in a FONTPATH environment variable.
-If the FONTPATH environment variable is not available, or is not checked by
-your target (i.e. Cygwin), then specify the full path to the font file as in:
-@example
--f /usr/X11R6/lib/X11/fonts/TTF/VeraBd.ttf
-@end example
-
-Usage Example:
-@example
-   # Remember to set the path to your fonts
-   FONTPATH="/cygdrive/c/WINDOWS/Fonts/"
-   FONTPATH="$FONTPATH:/usr/share/imlib2/data/fonts/"
-   FONTPATH="$FONTPATH:/usr/X11R6/lib/X11/fonts/TTF/"

-   # Time and date display
-   ffmpeg -f video4linux2 -i /dev/video0 \
-   -vhook 'vhook/drawtext.so -f VeraBd.ttf -t %A-%D-%T' movie.mpg
-
-     This example grabs video from the first capture card and outputs it to an
-     MPEG video, and places "Weekday-dd/mm/yy-hh:mm:ss" at the top left of the
-     frame, updated every second, using the Vera Bold TrueType Font, which
-     should exist in: /usr/X11R6/lib/X11/fonts/TTF/
-@end example
-
-Check the man page for strftime() for all the various ways you can format
-the date and time.
-
-@section watermark.c
-
-Command Line options:
-@multitable @columnfractions .2 .8
-@item @option{-m [0|1]}            @tab Mode (default: 0, see below)
-@item @option{-t 000000 - FFFFFF}  @tab Threshold, six digit hex number
-@item @option{-f <filename>}       @tab Watermark image filename, must be specified!
-@end multitable
-
-MODE 0:
- The watermark picture works like this (assuming color intensities 0..0xFF):
- Per color do this:
- If mask color is 0x80, no change to the original frame.
- If mask color is < 0x80 the absolute difference is subtracted from the
- frame. If result < 0, result = 0.
- If mask color is > 0x80 the absolute difference is added to the
- frame. If result > 0xFF, result = 0xFF.
-
- You can override the 0x80 level with the -t flag. E.g. if threshold is
- 000000 the color value of watermark is added to the destination.
-
- This way a mask that is visible both in light and dark pictures can be made
- (e.g. by using a picture generated by the Gimp and the bump map tool).
-
- An example watermark file is at:
- @url{http://engene.se/ffmpeg_watermark.gif}
-
-MODE 1:
- Per color do this:
- If mask color > threshold color then the watermark pixel is used.
-
-Example usage:
-@example
-   ffmpeg -i infile -vhook '/path/watermark.so -f wm.gif' -an out.mov
-   ffmpeg -i infile -vhook '/path/watermark.so -f wm.gif -m 1 -t 222222' -an out.mov

+
+@chapter Introduction
+
+Libavfilter is the filtering API of FFmpeg. It is the substitute of the
+now deprecated 'vhooks' and started as a Google Summer of Code project.
+
+Integrating libavfilter into the main FFmpeg repository is a work in
+progress. If you wish to try the unfinished development code of
+libavfilter then check it out from the libavfilter repository into
+some directory of your choice by:
+
+@example
+   svn checkout svn://svn.ffmpeg.org/soc/libavfilter
+@end example
+
+And then read the README file in the top directory to learn how to
+integrate it into ffmpeg and ffplay.
+
+But note that there may still be serious bugs in the code and its API
+and ABI should not be considered stable yet!
+
+@chapter Tutorial
+
+In libavfilter, it is possible for filters to have multiple inputs and
+multiple outputs.
+To illustrate the sorts of things that are possible, we can
+use a complex filter graph. For example, the following one:
+
+@example
+input --> split --> fifo -----------------------> overlay --> output
+            |                                        ^
+            |                                        |
+            +------> fifo --> crop --> vflip --------+
+@end example
+
+splits the stream in two streams, sends one stream through the crop filter
+and the vflip filter before merging it back with the other stream by
+overlaying it on top. You can use the following command to achieve this:
+
+@example
+./ffmpeg -i in.avi -s 240x320 -vfilters "[in] split [T1], fifo, [T2] overlay= 0:240 [out]; [T1] fifo, crop=0:0:-1:240, vflip [T2]
+@end example
+
+where input_video.avi has a vertical resolution of 480 pixels. The
+result will be that in output the top half of the video is mirrored
+onto the bottom half.
+
+Video filters are loaded using the @var{-vfilters} option passed to
+ffmpeg or to ffplay. Filters in the same linear chain are separated by
+commas. In our example, @var{split, fifo, overlay} are in one linear
+chain, and @var{fifo, crop, vflip} are in another. The points where
+the linear chains join are labeled by names enclosed in square
+brackets. In our example, that is @var{[T1]} and @var{[T2]}. The magic
+labels @var{[in]} and @var{[out]} are the points where video is input
+and output.
+
+Some filters take in input a list of parameters: they are specified
+after the filter name and an equal sign, and are separated each other
+by a semicolon.
+
+There exist so-called @var{source filters} that do not have a video
+input, and we expect in the future some @var{sink filters} that will
+not have video output.
+
+@chapter graph2dot
+
+The @file{graph2dot} program included in the FFmpeg @file{tools}
+directory can be used to parse a filter graph description and issue a
+corresponding textual representation in the dot language.
+
+Invoke the command:
+@example
+graph2dot -h
+@end example
+
+to see how to use @file{graph2dot}.
+
+You can then pass the dot description to the @file{dot} program (from
+the graphviz suite of programs) and obtain a graphical representation
+of the filter graph.
+
+For example the sequence of commands:
+@example
+echo @var{GRAPH_DESCRIPTION} | \
+tools/graph2dot -o graph.tmp && \
+dot -Tpng graph.tmp -o graph.png && \
+display graph.png
+@end example
+
+can be used to create and display an image representing the graph
+described by the @var{GRAPH_DESCRIPTION} string.
+
+@chapter Available video filters
+
+When you configure your FFmpeg build, you can disable any of the
+existing video filters.
+The configure output will show the video filters included in your
+build.
+
+Below is a description of the currently available video filters.
+
+@section crop
+
+Crop the input video to @var{x}:@var{y}:@var{width}:@var{height}.
+
+@example
+./ffmpeg -i in.avi -vfilters "crop=0:0:0:240" out.avi
+@end example
+
+@var{x} and @var{y} specify the position of the top-left corner of the
+output (non-cropped) area.
+
+The default value of @var{x} and @var{y} is 0.
+
+The @var{width} and @var{height} parameters specify the width and height
+of the output (non-cropped) area.
+
+A value of 0 is interpreted as the maximum possible size contained in
+the area delimited by the top-left corner at position x:y.
+
+For example the parameters:
+
+@example
+"crop=100:100:0:0"
+@end example
+
+will delimit the rectangle with the top-left corner placed at position
+100:100 and the right-bottom corner corresponding to the right-bottom
+corner of the input image.
+
+The default value of @var{width} and @var{height} is 0.
+
+@section format
+
+Convert the input video to one of the specified pixel formats.
+Libavfilter will try to pick one that is supported for the input to
+the next filter.
+
+The filter accepts a list of pixel format names, separated by ``:'',
+for example ``yuv420p:monow:rgb24''.
+
+The following command:
+
+@example
+./ffmpeg -i in.avi -vfilters "format=yuv420p" out.avi
+@end example
+
+will convert the input video to the format ``yuv420p''.
+
+@section noformat
+
+Force libavfilter not to use any of the specified pixel formats for the
+input to the next filter.
+
+The filter accepts a list of pixel format names, separated by ``:'',
+for example ``yuv420p:monow:rgb24''.
+
+The following command:
+
+@example
+./ffmpeg -i in.avi -vfilters "noformat=yuv420p, vflip" out.avi
+@end example
+
+will make libavfilter use a format different from ``yuv420p'' for the
+input to the vflip filter.
+
+@section null
+
+Pass the source unchanged to the output.
+
+@section scale
+
+Scale the input video to @var{width}:@var{height} and/or convert the image format.
+
+For example the command:
+
+@example
+./ffmpeg -i in.avi -vfilters "scale=200:100" out.avi
+@end example
+
+will scale the input video to a size of 200x100.
+
+If the input image format is different from the format requested by
+the next filter, the scale filter will convert the input to the
+requested format.
+
+If the value for @var{width} or @var{height} is 0, the respective input
+size is used for the output.
+
+If the value for @var{width} or @var{height} is -1, the scale filter will
+use, for the respective output size, a value that maintains the aspect
+ratio of the input image.
+
+The default value of @var{width} and @var{height} is 0.
+
+@section slicify
+
+Pass the images of input video on to next video filter as multiple
+slices.
+
+@example
+./ffmpeg -i in.avi -vfilters "slicify=32" out.avi
+@end example
+
+The filter accepts the slice height as parameter. If the parameter is
+not specified it will use the default value of 16.
+
+Adding this in the beginning of filter chains should make filtering
+faster due to better use of the memory cache.
+
+@section unsharp
+
+Sharpen or blur the input video. It accepts the following parameters:
+
+@multitable @columnfractions .2 .5 .1 .1 .1
+@headitem Name @tab Description @tab Min @tab Max @tab Default
+@item @var{luma_msize_x}

+A Quick Description Of Rate Distortion Theory.
+
+We want to encode a video, picture or piece of music optimally. What does
+"optimally" really mean? It means that we want to get the best quality at a
+given filesize OR we want to get the smallest filesize at a given quality
+(in practice, these 2 goals are usually the same).
+
+Solving this directly is not practical; trying all byte sequences 1
+megabyte in length and selecting the "best looking" sequence will yield
+256^1000000 cases to try.
+
+But first, a word about quality, which is also called distortion.
+Distortion can be quantified by almost any quality measurement one chooses.
+Commonly, the sum of squared differences is used but more complex methods
+that consider psychovisual effects can be used as well. It makes no
+difference in this discussion.
+
+
+First step: that rate distortion factor called lambda...
+Let's consider the problem of minimizing:
+
+  distortion + lambda*rate
+
+rate is the filesize
+distortion is the quality
+lambda is a fixed value choosen as a tradeoff between quality and filesize
+Is this equivalent to finding the best quality for a given max
+filesize? The answer is yes. For each filesize limit there is some lambda
+factor for which minimizing above will get you the best quality (using your
+chosen quality measurement) at the desired (or lower) filesize.
+
+
+Second step: splitting the problem.
+Directly splitting the problem of finding the best quality at a given
+filesize is hard because we do not know how many bits from the total
+filesize should be allocated to each of the subproblems. But the formula
+from above:
+
+  distortion + lambda*rate
+
+can be trivially split. Consider:
+
+  (distortion0 + distortion1) + lambda*(rate0 + rate1)
+
+This creates a problem made of 2 independent subproblems. The subproblems
+might be 2 16x16 macroblocks in a frame of 32x16 size. To minimize:
+
+  (distortion0 + distortion1) + lambda*(rate0 + rate1)
+
+we just have to minimize:
+
+  distortion0 + lambda*rate0
+
+and
+
+  distortion1 + lambda*rate1
+
+I.e, the 2 problems can be solved independently.

+Writing a table generator
+
+This documentation is preliminary.
+Parts of the API are not good and should be changed.
+
+Basic concepts
+
+A table generator consists of two files, *_tablegen.c and *_tablegen.h.
+The .h file will provide the variable declarations and initialization
+code for the tables, the .c calls the initialization code and then prints
+the tables as a header file using the tableprint.h helpers.
+Both of these files will be compiled for the host system, so to avoid
+breakage with cross-compilation neither of them may include, directly
+or indirectly, config.h or avconfig.h.
+Due to this, the .c file or Makefile may have to provide additional defines
+or stubs, though if possible this should be avoided.
+In particular, CONFIG_HARDCODED_TABLES should always be defined to 0.
+
+The .c file
+
+This file should include the *_tablegen.h and tableprint.h files and
+anything else it needs as long as it does not depend on config.h or
+avconfig.h.
+In addition to that it must contain a main() function which initializes
+all tables by calling the init functions from the .h file and then prints
+them.
+The printing code typically looks like this:
+    write_fileheader();
+    printf("static const uint8_t my_array[100] = {\n");
+    write_uint8_array(my_array, 100);
+    printf("};\n");
+
+write_fileheader() adds some minor things like a "this is a generated file"
+comment and some standard includes.
+tablegen.h defines some write functions for one- and two-dimensional arrays
+for standard types - they print only the "core" parts so they are easier
+to reuse for multi-dimensional arrays so the outermost {} must be printed
+separately.
+If there's no standard function for printing the type you need, the
+WRITE_1D_FUNC_ARGV macro is a very quick way to create one.
+See libavcodec/dv_tablegen.c for an example.
+
+
+The .h file
+
+This file should contain:
+ - one or more initialization functions
+ - the table variable declarations
+If CONFIG_HARDCODED_TABLES is set, the initialization functions should
+not do anything, and instead of the variable declarations the
+generated *_tables.h file should be included.
+Since that will be generated in the build directory, the path must be
+included, i.e.
+#include "libavcodec/example_tables.h"
+not
+#include "example_tables.h"
+
+Makefile changes
+
+To make the automatic table creation work, you must manually declare the
+new dependency.
+For this add a line similar to this:
+$(SUBDIR)example.o: $(SUBDIR)example_tables.h
+under the "ifdef CONFIG_HARDCODED_TABLES" section in the Makefile.

+This is a quick description of the viterbi aka dynamic programing
+algorthm.
+
+Its reason for existence is that wikipedia has become very poor on
+describing algorithms in a way that makes it useable for understanding
+them or anything else actually. It tends now to describe the very same
+algorithm under 50 different names and pages with few understandable
+by even people who fully understand the algorithm and the theory behind.
+
+Problem description: (that is what it can solve)
+assume we have a 2d table, or you could call it a graph or matrix if you
+prefer
+
+    O   O   O   O   O   O   O
+
+    O   O   O   O   O   O   O
+
+    O   O   O   O   O   O   O
+
+    O   O   O   O   O   O   O
+
+
+That table has edges connecting points from each column to the next column
+and each edge has a score like: (only some edge and scores shown to keep it
+readable)
+
+
+    O--5--O-----O-----O-----O-----O
+     2   / 7   / \   / \   / \   /
+      \ /   \ /   \ /   \ /   \ /
+    O7-/--O--/--O--/--O--/--O--/--O
+     \/ \/ 1/ \/ \/ \/ \/ \/ \/ \/
+     /\ /\ 2\ /\ /\ /\ /\ /\ /\ /\
+    O3-/--O--/--O--/--O--/--O--/--O
+      / \   / \   / \   / \   / \
+     1   \ 9   \ /   \ /   \ /   \
+    O--2--O--1--O--5--O--3--O--8--O
+
+
+
+Our goal is to find a path from left to right through it which
+minimizes the sum of the score of all edges.
+(and of course left/right is just a convention here it could be top down too)
+Similarly the minimum could be the maximum by just fliping the sign,
+Example of a path with scores:
+
+    O   O   O   O   O   O   O
+
+>---O.  O   O  .O-2-O   O   O
+      5.     .7      .
+    O   O-1-O   O   O 8 O   O
+                       .
+    O   O   O   O   O   O-1-O---> (sum here is 24)
+
+
+The viterbi algorthm now solves this simply column by column
+For the previous column each point has a best path and a associated
+score:
+
+    O-----5     O
+     \
+      \
+    O  \  1     O
+        \/
+        /\
+    O  /  2     O
+      /
+     /
+    O-----2     O
+
+
+To move one column forward we just need to find the best path and associated
+scores for the next column
+here are some edges we could choose from:
+
+
+    O-----5--3--O
+     \      \8
+      \       \
+    O  \  1--9--O
+        \/  \3
+        /\     \
+    O  /  2--1--O
+      /     \2
+     /        \
+    O-----2--4--O
+
+Finding the new best pathes and scores for each point of our new column is
+trivial given we know the previous column best pathes and scores:
+
+    O-----0-----8
+     \
+      \
+    O  \  0----10
+        \/
+        /\
+    O  /  0-----3
+      /     \
+     /        \
+    O     0     4
+
+
+the viterbi algorthm continues exactly like this column for column until the
+end and then just picks the path with the best score (above that would be the
+one with score 3)

+ * Summary of MDCT Coefficient Grouping:
+ * The individual MDCT coefficient indices are often referred to in the
+ * (E-)AC-3 specification as frequency bins.  These bins are grouped together
+ * into subbands of 12 coefficients each.  The subbands are grouped together
+ * into bands as defined in the bitstream by the band structures, which
+ * determine the number of bands and the size of each band.  The full spectrum
+ * of 256 frequency bins is divided into 1 DC bin + 21 subbands = 253 bins.
+ * This system of grouping coefficients is used for channel bandwidth, stereo
+ * rematrixing, channel coupling, enhanced coupling, and spectral extension.
