1f3baf7218 lavc/vp9: reset segmentation fields when segmentation isn't enabled
Fields under the segmentation switch are never reset on a new frame, and
retain the value from the previous frame. This bugs out a bunch of
hwaccel drivers when segmentation is disabled but update_map isn't
reset because they don't ignore values behind switches. This commit also
resets the temporal field, though it may not be required.

We also do this for vp8 [1] so this commit is just mirroring the vp8
logic.

This fixes an issue with certain samples [2] that causes blocky
artifacts with vaapi, d3d11va and cuda (and possibly others).
Mesa worked around [3] this by ignoring these fields if
segmentation.enabled is 0, but d3d11va still displays blocky artifacts.

a6a9e0fee7 libavformat/hlsenc.c: Populate OTI using AAC profile in write_codec_attr.
This patch populates the third entry for HLS codec attribute using the
AAC profile.

The HLS specifications[1] require this value to be the Object Type ID as
referred to in table 1.3 of ISO/IEC 14496-3:2009[2].

The numerical constants in the code refer to these OTIs minus one, as
documented in commit 372597e[3], confirmed by comparing the values in the
code with the values in the table mentioned above.

Links:
1: https://datatracker.ietf.org/doc/html/rfc6381#section-3.3
2: https://csclub.uwaterloo.ca/~ehashman/ISO14496-3-2009.pdf
3: 372597e538

Changes in this version:
- Default value set to "mp4a.40.2" when profile is unknown for backward
  compatibility.

defa085fc8 avfilter/buffersrc: fix overriding unknown channel layouts with negotiated one
Fixes ffplay playback of unknown layouts, when SDL directly supports the audio
format, such as:

ffplay -f lavfi anullsrc=cl=2C,aformat=s16

Without the patch, "Channel layout change is not supported" errors are
generated because buffersrc (unknown 2 channel) and buffersink (stereo)
negotiated a stereo layout, but the stereo layout was never stored in the
BufferSourceContext.

This fixes a regression of 7251f90972, but this
is more of a regression of the avfilter channel layout conversion
(1f96db959c).

ffplay -f lavfi -i "sine=440:r=8000:samples_per_frame=32,aresample=24000:filter_size=1:phase_shift=0"

Fix this by rounding the fixed point fractions up instead of down.

68f0e9645d avformat/mxfdec: do not use AnyType when resolving Descriptors and MultipleDescriptors
By using AnyType for resolving a strong reference we searched among all types,
not just the ones which can be the target of the reference, which in some cases
caused to find the wrong type, if the metadata set UUIDs were not unique.

UUIDs do not have to be unique if their type sets them apart, SMPTE 377M says:

> StrongRef: 'One to One’ relationship between sets and implemented in MXF
> with UUIDs. Strong References are typed which means that the definition
> identifies the kind of set which is the target of the reference.

352fe0d4bf avformat/mov_chan: never override number of channels based on chan atom
The channel designation metadata should not override the number of channels.
Let's warn the user if it is inconsistent, and keep the channel layout
unspecified.

Before the conversion to the channel layout API the code only set the mask, but
never overridden the channel count, so this restores the old behaviour.

f471851169 avformat/mov_chan: do not assume channels are in native order
Existing code could have caused wrong channel order signalling or reduced
channel count if a channel designation appeared multiple times. This is
actually an old bug, but the conversion to the new channel layout API made it
visible, because now the code overrides the proper channel count with the one
calculated from the mask.

a3440ddec3 doc/html: fix styling issue with Texinfo 7.0
Texinfo 7.0 produces quite different HTML to Texinfo 6.8. Without
this change, enumerated option flags (i.e. Possible values of x
are...) render as white text on a white background with Texinfo 7.0
and are unreadable. This change removes a style for the selector
`.table .table` which causes the background to turn white for these
elements. As far as I can tell, it is not actually used anywhere in
files generated by Texinfo 6.8.

db73e0bb1a doc/html: support texinfo 7.0
Resolves trac ticket #10636 (http://trac.ffmpeg.org/ticket/10636).

Texinfo 7.0, released in November 2022, changed the names of various
functions. Compiling docs with Texinfo 7.0 resulted in warnings and
improperly formatted documentation. More old names appear to have
been removed in Texinfo 7.1, released October 2023, which causes docs
compilation to fail.

This commit addresses the issue by adding logic to switch between the old
and new function names depending on the Texinfo version. Texinfo 6.8
produces identical documentation before and after the patch.

6c176df7e9 avformat/hls: reduce default max reload to 3
The 1000 did result in the appearance of a never ending reload loop

The RFC mandates that "If the client reloads a Playlist file and finds that it has not
changed, then it MUST wait for a period of one-half the target
duration before retrying." and if it has changed
"the client MUST wait for at least the target duration before attempting to reload the
Playlist file again"

Trying to reload 3 times seems a better default than 1000 given these
durations

3c56b5c3df avcodec/jpeg2000dec: jpeg2000 has its own lowres option
jpeg2000 overrides the global lowres variable with a lowres field called reduction_factor
ffmpeg -lowres X causes the reduction_factor to be set
ffplay -lowres X causes both lowres and the reduction_factor to be set
ossfuss sets only lowres

only the ffmpeg variant works. This patch tries to make the other 2 work.

Alternative we could just error out if things are inconsistent.
More complex restructuring should be limited to the master branch
to keep this reasonably easy to backport

Enable the checked bitreader to avoid overread.

execution.
Alternatively we could add manual checks so that no overread can happen. This would be
slightly faster but a bit more work and a bit more fragile

566aa38d98 libavformat/riffec: Zero-initialize channels in ff_get_wav_header
Clang's static analyzer complains that leaving the  variable
uninitialized could lead to a code path where the uninitialized value is
written to  at the end of this function.
This patch simply zero-initializes that variable to avoid that.

e5b5dd6653 avcodec/libsvtav1: use larger of bit rate and max rate for buffer size
Generally if maxrate is set, the calculation should be maxrate over
bufsize. This additionally enables CRF + maxrate & bufsize usage.

In order to keep negative values from enabling zero to be treated
as larger and causing a division by zero, check that one of the
variables is larger than zero.

3344d47a88 avcodec/libsvtav1: remove compressed_ten_bit_format and simplify alloc_buffer
compressed_ten_bit_format has been deprecated upstream and has no effect
and can be removed. Plus, technically it was never used in the first place
since it would require the app (ffmpeg) to set it and do additional
processing of the input frames.

Also simplify alloc_buffer by removing calculations relating to the
non-existant processing.

name prefixes were changed from EXT to KHR. It's a bit too soon to be
depending on it, so rather than bumping, just remove these for now.

30d432f205 avcodec/libjxldec: fix gamma22 and gamma28 recognition
Gamma 2.2 and Gamma 2.8 are tagged in the file as 0.45455 and 0.35714,
respectively (i.e. 1/2.2 and 1/2.8). Trying to identify them as 2.2 and
2.8 instead of these values will cause the transfer function to not
properly be recognized. This patch fixes this.

a6e26053c2 swscale: aarch64: Fix yuv2rgb with negative strides
Treat the 32 bit stride registers as signed.

Alternatively, we could make the stride arguments ptrdiff_t instead
of int, and changing all of the assembly to operate on these
registers with their full 64 bit width, but that's a much larger
and more intrusive change (and risks missing some operation, which
would clamp the intermediates to 32 bit still).

b4a4a31499 avcodec/atrac3plus: reorder channels to match the output layout
The order in which the channels are coded in the bitstream do not always follow
the native, bitmask-based order of channels both signaled by the WAV container
and forced by this same decoder. This is the case with layouts containing an
LFE channel, as it's always coded last.

Fixes ticket #9964.

e7dd643419 lavf/async: Fix ring_write return value
This fixes a regression from commit 36117968ad.

wrapped_url_read() used to be able to return positive number from
ffurl_read(). It relies on the result to check if EOF is reached in
async_buffer_task().

But FIFO callbacks must return 0 on success. This should be handled
in ring_write() instead.

Test case:
  ffmpeg -f lavfi -i testsrc -t 1 test.mp4
  ffmpeg -i async:test.mp4

Also, don't write the sample_rate value propagated by encoders like libopus.

f202a1fdf7 avformat/dashdec: Fix crash on invalid input/ENOMEM, fix leak
In case a SupplementalProperty node exists in an adaptationset,
it is searched for a "schemeIdUri" property via xmlGetProp().
Whatever xmlGetProp() returns is then compared via av_strcasecmp()
to a string literal. xmlGetProp() can return NULL, namely in case
no "schemeIdUri" exists and (given that this string is allocated)
presumably also on allocation failure. No check for NULL is done,
so this may crash.

Furthermore, the string returned by xmlGetProp() needs to be freed
with xmlFree(), but this is not done either.

This commit fixes both of these issues; they existed since this code
has been added in 10d008f0fd.

This has been found while investigating ticket #9697. The continuous
leaks might very well be the reason behind the observed slowdown.

9772ba1b6a lavc/videotoolbox: do not pass AVCodecContext to decoder output callback
The opaque parameter for the callback is set in videotoolbox_start(),
called when the hwaccel is initialized. When frame threading is used,
avctx will be the context corresponding to the frame thread currently
doing the decoding. Using this same codec context in all subsequent
invocations of the decoder callback (even those triggered by a different
frame thread) is unsafe, and broken after
cc867f2c09, since each frame thread now
cleans up its hwaccel state after decoding each frame.

Fix this by passing hwaccel_priv_data as the opaque parameter, which
exists in a single instance forwarded between all frame threads.

The only other use of AVCodecContext in the decoder output callback is
as a logging context. For this purpose, store a logging context in
hwaccel_priv_data.

2d04a18264 avcodec/arm/sbcenc: avoid callee preserved vfp registers
When compiling FFmpeg with GCC-9, some very random segfaults were
observed in code which had previously called down into the SBC encoder
NEON assembly routines. This was caused by these functions clobbering
some of the vfp callee saved registers (d8 - d15 aka q4 - q7). GCC was
using these registers to save local variables, but after these
functions returned, they would contain garbage.

Fix by reallocating the registers in the two affected functions in
the following way:
 ff_sbc_analyze_4_neon: q2-q5 => q8-q11, then q1-q4 => q8-q11
 ff_sbc_analyze_8_neon: q2-q9 => q8-q15

The reason for using these replacements is to keep closely related
sets of registers consecutively numbered which hopefully makes the
code more easy to follow. Since this commit only reallocates
registers, it should have no performance impact.

bc7df3bc64 avcodec/pngdec: Fix APNG_DISPOSE_OP_BACKGROUND
APNG works with a single reference frame and an output frame.
According to the spec, decoding APNG works by decoding
the current IDAT/fdAT chunks (which decodes to a rectangular
subregion of the whole image region), followed by either
overwriting the region of the output frame with the newly
decoded data or by blending the newly decoded data with
the data from the reference frame onto the current subregion
of the output frame. The remainder of the output frame
is just copied from the reference frame.
Then the reference frame might be left untouched
(APNG_DISPOSE_OP_PREVIOUS), it might be replaced by the output
frame (APNG_DISPOSE_OP_NONE) or the rectangular subregion
corresponding to the just decoded frame has to be reset
to black (APNG_DISPOSE_OP_BACKGROUND).

The latter case is not handled correctly by our decoder:
It only performs resetting the rectangle in the reference frame
when decoding the next frame; and since commit
b593abda6c it does not reset
the reference frame permanently, but only temporarily (i.e.
it only affects decoding the frame after the frame with
APNG_DISPOSE_OP_BACKGROUND). This is a problem if the
frame after the APNG_DISPOSE_OP_BACKGROUND frame uses
APNG_DISPOSE_OP_PREVIOUS, because then the frame after
the APNG_DISPOSE_OP_PREVIOUS frame has an incorrect reference
frame. (If it is not followed by an APNG_DISPOSE_OP_PREVIOUS
frame, the decoder only keeps a reference to the output frame,
which is ok.)

This commit fixes this by being much closer to the spec
than the earlier code: Resetting the background is no longer
postponed until the next frame; instead it is applied to
the reference frame.

Fixes ticket #9602.

(For multithreaded decoding it was actually already broken
since commit 5663301560d77486c7f7c03c1aa5f542fab23c24.)

db2d52e1ff avcodec/libvpx: fix assembling vp9 packets with alpha channel
There's no warranty that vpx_codec_encode() will generate a list with the same
amount of packets for both the yuv planes encoder and the alpha plane encoder,
so queueing packets based on what the main encoder returns will fail when the
amount of packets in both lists differ.
Queue all data packets for every vpx_codec_encode() call from both encoders
before attempting to assemble output AVPackets out of them.

83feded492 avdevice/avdevice: fix return value of avdevice_list_devices()
According to API docs avdevice_list_devices(), avdevice_list_input_sources()
and avdevice_list_input_sinks() should return the number of autodetected
devices on success. This is redundant with AVDeviceInfoList->nb_devices so it
was not noticed earlier that none of the underlying device list functions work
like that.

Let's fix it in generic code to make it in line with the API docs.

Fixes ticket #9820.

b21d387d6f ffmpeg: add option -isync
This is a per-file input option that adjusts an input's timestamps
with reference to another input, so that emitted packet timestamps
account for the difference between the start times of the two inputs.

Typical use case is to sync two or more live inputs such as from capture
devices. Both the target and reference input source timestamps should be
based on the same clock source.

If either input lacks starting timestamps, then no sync adjustment is made.

NOTICE for Package Maintainers
------------------------------
- It is recommended to build FFmpeg twice, first with minimal external dependencies so
that 3rd party packages, which depend on FFmpegs libavutil/libavfilter/libavcodec/libavformat
can then be built. And last build FFmpeg with full dependencies (which may in turn depend on
some of these 3rd party packages). This avoids circular dependencies during build.

│ RELEASE NOTES for FFmpeg 5.1 "Riemann" LTS
└────────────────────────────────────────────
The FFmpeg Project proudly presents FFmpeg 8.0 "Huffman", about 11
months after the release of FFmpeg 7.1.
The FFmpeg Project proudly presents FFmpeg 5.1 "Riemann" LTS, about 6
months after the release of FFmpeg 5.0, our first Long Term Support
release. While several past FFmpeg releases have enjoyed long term
support, this is the first release where such an intention is made
clear at release.
A complete Changelog is available at the root of the project, and the
complete Git history on https://git.ffmpeg.org/gitweb/ffmpeg.git

This applies a specific fixup to some Blu-ray streams which contain
redundant PPSs modifying irrelevant parameters of the stream which
confuse other transformations which require correct extradata.
The encoder used on these impacted streams adds extra PPSs throughout
the stream, varying the initial QP and whether weighted prediction
was enabled. This causes issues after copying the stream into
a global header container, as the starting PPS is not suitable
for the rest of the stream. One side effect, for example,
is seeking will return garbled output until a new PPS appears.
This BSF removes the extra PPSs and rewrites the slice headers
such that the stream uses a single leading PPS in the global header,
which resolves the issue.

within the stream are removed.

@chapter Organisation
The FFmpeg project is organized through a community working on global consensus.
Decisions are taken by the ensemble of active members, through voting and are aided by two committees.
@anchor{General Assembly}
@chapter General Assembly
The ensemble of active members is called the General Assembly (GA).
The General Assembly is sovereign and legitimate for all its decisions regarding the FFmpeg project.
The General Assembly is made up of active contributors.
Contributors are considered "active contributors" if they have authored more than 20 patches in the last 36 months in the main FFmpeg repository, or if they have been voted in by the GA.
The list of active contributors is updated twice each year, on 1st January and 1st July, 0:00 UTC.
Additional members are added to the General Assembly through a vote after proposal by a member of the General Assembly. They are part of the GA for two years, after which they need a confirmation by the GA.
A script to generate the current members of the general assembly (minus members voted in) can be found in `tools/general_assembly.pl`.
@anchor{Voting}
@chapter Voting
Voting is done using a ranked voting system, currently running on https://vote.ffmpeg.org/ .
Majority vote means more than 50% of the expressed ballots.
@anchor{Technical Committee}
@chapter Technical Committee
The Technical Committee (TC) is here to arbitrate and make decisions when technical conflicts occur in the project. They will consider the merits of all the positions, judge them and make a decision.
The TC resolves technical conflicts but is not a technical steering committee.
Decisions by the TC are binding for all the contributors.
Decisions made by the TC can be re-opened after 1 year or by a majority vote of the General Assembly, requested by one of the member of the GA.
The TC is elected by the General Assembly for a duration of 1 year, and is composed of 5 members. Members can be re-elected if they wish. A majority vote in the General Assembly can trigger a new election of the TC.
The members of the TC can be elected from outside of the GA. Candidates for election can either be suggested or self-nominated.
The conflict resolution process is detailed in the resolution process document.
The TC can be contacted at <tc@@ffmpeg>.
@anchor{Resolution Process}
@section Resolution Process
The Technical Committee (TC) is here to arbitrate and make decisions when technical conflicts occur in the project.
The TC main role is to resolve technical conflicts. It is therefore not a technical steering committee, but it is understood that some decisions might impact the future of the project.
@subsection Seizing
The TC can take possession of any technical matter that it sees fit.
To involve the TC in a matter, email tc@ or CC them on an ongoing discussion.
As members of TC are developers, they also can email tc@ to raise an issue.
@subsection Announcement
The TC, once seized, must announce itself on the main mailing list, with a [TC] tag.
The TC has 2 modes of operation: a RFC one and an internal one.
If the TC thinks it needs the input from the larger community, the TC can call for a RFC. Else, it can decide by itself.
The decision to use a RFC process or an internal discussion is a discretionary decision of the TC.
The TC can also reject a seizure for a few reasons such as: the matter was not discussed enough previously; it lacks expertise to reach a beneficial decision on the matter; or the matter is too trivial.
@subsection RFC call
In the RFC mode, one person from the TC posts on the mailing list the technical question and will request input from the community.
The mail will have the following specification:
a precise title
a specific tag [TC RFC]
a top-level email
contain a precise question that does not exceed 100 words and that is answerable by developers
may have an extra description, or a link to a previous discussion, if deemed necessary,
contain a precise end date for the answers.
The answers from the community must be on the main mailing list and must have the following specification:
keep the tag and the title unchanged
limited to 400 words
a first-level, answering directly to the main email
answering to the question.
Further replies to answers are permitted, as long as they conform to the community standards of politeness, they are limited to 100 words, and are not nested more than once. (max-depth=2)
After the end-date, mails on the thread will be ignored.
Violations of those rules will be escalated through the Community Committee.
After all the emails are in, the TC has 96 hours to give its final decision. Exceptionally, the TC can request an extra delay, that will be notified on the mailing list.
@subsection Within TC
In the internal case, the TC has 96 hours to give its final decision. Exceptionally, the TC can request an extra delay.
@subsection Decisions
The decisions from the TC will be sent on the mailing list, with the [TC] tag.
Internally, the TC should take decisions with a majority, or using ranked-choice voting.
Each TC member must vote on such decision according to what is, in their view, best for the project.
If a TC member feels they are affected by a conflict of interest with regards to the case, they should announce it and recuse themselves from the TC
discussion and vote.
A conflict of interest is presumed to occur when a TC member has a personal interest (e.g. financial) in a specific outcome of the case.
The decision from the TC should be published with a summary of the reasons that lead to this decision.
The decisions from the TC are final, until the matters are reopened after no less than one year.
@anchor{Community Committee}
@chapter Community Committee
The Community Committee (CC) is here to arbitrage and make decisions when inter-personal conflicts occur in the project. It will decide quickly and take actions, for the sake of the project.
The CC can remove privileges of offending members, including removal of commit access and temporary ban from the community.
Decisions made by the CC can be re-opened after 1 year or by a majority vote of the General Assembly. Indefinite bans from the community must be confirmed by the General Assembly, in a majority vote.
The CC is elected by the General Assembly for a duration of 1 year, and is composed of 5 members. Members can be re-elected if they wish. A majority vote in the General Assembly can trigger a new election of the CC.
The members of the CC can be elected from outside of the GA. Candidates for election can either be suggested or self-nominated.
The CC is governed by and responsible for enforcing the Code of Conduct.
The CC can be contacted at <cc@@ffmpeg>.
@anchor{Code of Conduct}
@chapter 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."

HEVC (AKA ITU-T H.265 or ISO/IEC 23008-2) decoder.
The decoder supports MV-HEVC multiview streams with at most two views. Views to
be output are selected by supplying a list of view IDs to the decoder (the
@option{view_ids} option). This option may be set either statically before
decoder init, or from the @code{get_format()} callback - useful for the case
when the view count or IDs change dynamically during decoding.
Only the base layer is decoded by default.

specifiers as documented in its manual, rather than the options documented here.
@subsection Options
@table @option

in the active VPS. The array is empty for single-layer video.
The value of this option is guaranteed to be accurate when read from the
@code{get_format()} callback. It may also be set at other times (e.g. after
opening the decoder), but the value is informational only and may be incorrect
(e.g. when the stream contains multiple distinct VPS NALUs).

@item -ass_single_rect @var{boolean}
ARIB STD-B24 specifies that some captions may be displayed at different
positions at a time (multi-rectangle subtitle).
Since some players (e.g., old @dfn{mpv}) can't handle multiple ASS rectangles
in a single AVSubtitle, or multiple ASS rectangles of indeterminate duration
with the same start timestamp, this option can change the behavior so that
all the texts are displayed in a single ASS rectangle.
The default is @var{false}.
If your player cannot handle AVSubtitles with multiple ASS rectangles properly,
set this option to @var{true} or define @env{ASS_SINGLE_RECT=1} to change
default behavior at compilation.

japanese special characters with halfwidth ones.
The default is @var{true}.
@item -replace_msz_glyph @var{boolean}
Specify whether to replace MSZ (Middle Size; half width) characters
with halfwidth glyphs if the fonts supports it.
This option works under FreeType or DirectWrite renderer
with Adobe-Japan1 compliant fonts.
e.g., IBM Plex Sans JP, Morisawa BIZ UDGothic, Morisawa BIZ UDMincho,
Yu Gothic, Yu Mincho, and Meiryo.
The default is @var{true}.
@item -canvas_size @var{image_size}
Specify the resolution of the canvas to render subtitles to; usually, this
should be frame size of input video.
This only applies when @code{-subtitle_type} is set to @var{bitmap}.
The libaribcaption decoder assumes input frame size for bitmap rendering as below:
@enumerate
@item
PROFILE_A : 1440 x 1080 with SAR (PAR) 4:3
@item
PROFILE_C : 320 x 180 with SAR (PAR) 1:1
@end enumerate
If actual frame size of input video does not match above assumption,
the rendered captions may be distorted.
To make the captions undistorted, add @code{-canvas_size} option to specify
actual input video size.
Note that the @code{-canvas_size} option is not required for video with
different size but same aspect ratio.
In such cases, the caption will be stretched or shrunk to actual video size
if @code{-canvas_size} option is not specified.
If @code{-canvas_size} option is specified with different size,
the caption will be stretched or shrunk as specified size with calculated SAR.

@section dvdvideo
DVD-Video demuxer, powered by libdvdnav and libdvdread.
Can directly ingest DVD titles, specifically sequential PGCs, into
a conversion pipeline. Menu assets, such as background video or audio,
can also be demuxed given the menu's coordinates (at best effort).
Block devices (DVD drives), ISO files, and directory structures are accepted.
Activate with @code{-f dvdvideo} in front of one of these inputs.
This demuxer does NOT have decryption code of any kind. You are on your own
working with encrypted DVDs, and should not expect support on the matter.
Underlying playback is handled by libdvdnav, and structure parsing by libdvdread.
FFmpeg must be built with GPL library support available as well as the
configure switches @code{--enable-libdvdnav} and @code{--enable-libdvdread}.
You will need to provide either the desired "title number" or exact PGC/PG coordinates.
Many open-source DVD players and tools can aid in providing this information.
If not specified, the demuxer will default to title 1 which works for many discs.
However, due to the flexibility of the format, it is recommended to check manually.
There are many discs that are authored strangely or with invalid headers.
If the input is a real DVD drive, please note that there are some drives which may
silently fail on reading bad sectors from the disc, returning random bits instead
which is effectively corrupt data. This is especially prominent on aging or rotting discs.
A second pass and integrity checks would be needed to detect the corruption.
This is not an FFmpeg issue.
@subsection Background
DVD-Video is not a directly accessible, linear container format in the
traditional sense. Instead, it allows for complex and programmatic playback of
carefully muxed MPEG-PS streams that are stored in headerless VOB files.
To the end-user, these streams are known simply as "titles", but the actual
logical playback sequence is defined by one or more "PGCs", or Program Group Chains,
within the title. The PGC is in turn comprised of multiple "PGs", or Programs",
which are the actual video segments (and for a typical video feature, sequentially
ordered). The PGC structure, along with stream layout and metadata, are stored in
IFO files that need to be parsed. PGCs can be thought of as playlists in easier terms.
An actual DVD player relies on user GUI interaction via menus and an internal VM
to drive the direction of demuxing. Generally, the user would either navigate (via menus)
or automatically be redirected to the PGC of their choice. During this process and
the subsequent playback, the DVD player's internal VM also maintains a state and
executes instructions that can create jumps to different sectors during playback.
This is why libdvdnav is involved, as a linear read of the MPEG-PS blobs on the
disc (VOBs) is not enough to produce the right sequence in many cases.
There are many other DVD structures (a long subject) that will not be discussed here.
NAV packets, in particular, are handled by this demuxer to build accurate timing
but not emitted as a stream. For a good high-level understanding, refer to:

@subsection Options
This demuxer accepts the following options:
@table @option
@item title @var{int}
The title number to play. Must be set if @option{pgc} and @option{pg} are not set.
Not applicable to menus.
Default is 0 (auto), which currently only selects the first available title (title 1)
and notifies the user about the implications.
@item chapter_start @var{int}
The chapter, or PTT (part-of-title), number to start at. Not applicable to menus.
Default is 1.
@item chapter_end @var{int}
The chapter, or PTT (part-of-title), number to end at. Not applicable to menus.
Default is 0, which is a special value to signal end at the last possible chapter.
@item angle @var{int}
The video angle number, referring to what is essentially an additional
video stream that is composed from alternate frames interleaved in the VOBs.
Not applicable to menus.
Default is 1.
@item region @var{int}
The region code to use for playback. Some discs may use this to default playback
at a particular angle in different regions. This option will not affect the region code
of a real DVD drive, if used as an input. Not applicable to menus.
Default is 0, "world".
@item menu @var{bool}
Demux menu assets instead of navigating a title. Requires exact coordinates
of the menu (@option{menu_lu}, @option{menu_vts}, @option{pgc}, @option{pg}).
Default is false.
@item menu_lu @var{int}

Default is 1, the first language unit.
@item menu_vts @var{int}
The VTS where the menu lives, or 0 if it is a VMG menu (root-level).
Default is 1, menu of the first VTS.
@item pgc @var{int}

Alternative to setting @option{title}.
Chapter markers are not supported at this time.
Default is 1, the first PG of the PGC.
@item preindex @var{bool}
Enable this to have accurate chapter (PTT) markers and duration measurement,
which requires a slow second pass read in order to index the chapter marker
timestamps from NAV packets. This is non-ideal extra work for real optical drives.
It is recommended and faster to use this option with a backup of the DVD structure
stored on a hard drive. Not compatible with @option{pgc} and @option{pg}.
Default is 0, false.
@item trim @var{bool}
Skip padding cells (i.e. cells shorter than 1 second) from the beginning.
There exist many discs with filler segments at the beginning of the PGC,
often with junk data intended for controlling a real DVD player's
buffering speed and with no other material data value.

# FFmpeg project
## Organisation
The FFmpeg project is organized through a community working on global consensus.
Decisions are taken by the ensemble of active members, through voting and
are aided by two committees.
## General Assembly
The ensemble of active members is called the General Assembly (GA).
The General Assembly is sovereign and legitimate for all its decisions
regarding the FFmpeg project.
The General Assembly is made up of active contributors.
Contributors are considered "active contributors" if they have pushed more
than 20 patches in the last 36 months in the main FFmpeg repository, or
if they have been voted in by the GA.
Additional members are added to the General Assembly through a vote after
proposal by a member of the General Assembly.
They are part of the GA for two years, after which they need a confirmation by
the GA.
## Voting
Voting is done using a ranked voting system, currently running on https://vote.ffmpeg.org/ .
Majority vote means more than 50% of the expressed ballots.
## Technical Committee
The Technical Committee (TC) is here to arbitrate and make decisions when
technical conflicts occur in the project.
They will consider the merits of all the positions, judge them and make a
decision.
The TC resolves technical conflicts but is not a technical steering committee.
Decisions by the TC are binding for all the contributors.
Decisions made by the TC can be re-opened after 1 year or by a majority vote
of the General Assembly, requested by one of the member of the GA.
The TC is elected by the General Assembly for a duration of 1 year, and
is composed of 5 members.
Members can be re-elected if they wish. A majority vote in the General Assembly
can trigger a new election of the TC.
The members of the TC can be elected from outside of the GA.
Candidates for election can either be suggested or self-nominated.
The conflict resolution process is detailed in the [resolution process](resolution_process.md) document.
## Community committee
The Community Committee (CC) is here to arbitrage and make decisions when
inter-personal conflicts occur in the project. It will decide quickly and
take actions, for the sake of the project.
The CC can remove privileges of offending members, including removal of
commit access and temporary ban from the community.
Decisions made by the CC can be re-opened after 1 year or by a majority vote
of the General Assembly. Indefinite bans from the community must be confirmed
by the General Assembly, in a majority vote.
The CC is elected by the General Assembly for a duration of 1 year, and is
composed of 5 members.
Members can be re-elected if they wish. A majority vote in the General Assembly
can trigger a new election of the CC.
The members of the CC can be elected from outside of the GA.
Candidates for election can either be suggested or self-nominated.
The CC is governed by and responsible for enforcing the Code of Conduct.

# Technical Committee
_This document only makes sense with the rules from [the community document](community)_.
The Technical Committee (**TC**) is here to arbitrate and make decisions when
technical conflicts occur in the project.
The TC main role is to resolve technical conflicts.
It is therefore not a technical steering committee, but it is understood that
some decisions might impact the future of the project.
# Process
## Seizing
The TC can take possession of any technical matter that it sees fit.
To involve the TC in a matter, email tc@ or CC them on an ongoing discussion.
As members of TC are developers, they also can email tc@ to raise an issue.
## Announcement
The TC, once seized, must announce itself on the main mailing list, with a _[TC]_ tag.
The TC has 2 modes of operation: a RFC one and an internal one.
If the TC thinks it needs the input from the larger community, the TC can call
for a RFC. Else, it can decide by itself.
If the disagreement involves a member of the TC, that member should recuse
themselves from the decision.
The decision to use a RFC process or an internal discussion is a discretionary
decision of the TC.
The TC can also reject a seizure for a few reasons such as:
the matter was not discussed enough previously; it lacks expertise to reach a
beneficial decision on the matter; or the matter is too trivial.
### RFC call
In the RFC mode, one person from the TC posts on the mailing list the
technical question and will request input from the community.
The mail will have the following specification:
* a precise title
* a specific tag [TC RFC]
* a top-level email
* contain a precise question that does not exceed 100 words and that is answerable by developers
* may have an extra description, or a link to a previous discussion, if deemed necessary,
* contain a precise end date for the answers.
The answers from the community must be on the main mailing list and must have
the following specification:
* keep the tag and the title unchanged
* limited to 400 words
* a first-level, answering directly to the main email
* answering to the question.
Further replies to answers are permitted, as long as they conform to the
community standards of politeness, they are limited to 100 words, and are not
nested more than once. (max-depth=2)
After the end-date, mails on the thread will be ignored.
Violations of those rules will be escalated through the Community Committee.
After all the emails are in, the TC has 96 hours to give its final decision.
Exceptionally, the TC can request an extra delay, that will be notified on the
mailing list.
### Within TC
In the internal case, the TC has 96 hours to give its final decision.
Exceptionally, the TC can request an extra delay.
## Decisions
The decisions from the TC will be sent on the mailing list, with the _[TC]_ tag.
Internally, the TC should take decisions with a majority, or using
ranked-choice voting.
The decision from the TC should be published with a summary of the reasons that
lead to this decision.
The decisions from the TC are final, until the matters are reopened after
no less than one year.

@chapter Coding Rules
@section Language
FFmpeg is mainly programmed in the ISO C11 language, except for the public
headers which must stay C99 compatible.
Compiler-specific extensions may be used with good reason, but must not be
depended on, i.e. the code must still compile and work with compilers lacking
the extension.
The following C99 features must not be used anywhere in the codebase:
@itemize @bullet
@item
variable-length arrays;
@item
complex numbers;
@end itemize
@subsection SIMD/DSP
@anchor{SIMD/DSP}
As modern compilers are unable to generate efficient SIMD or other
performance-critical DSP code from plain C, handwritten assembly is used.
Usually such code is isolated in a separate function. Then the standard approach
is writing multiple versions of this function a plain C one that works
everywhere and may also be useful for debugging, and potentially multiple
architecture-specific optimized implementations. Initialization code then
chooses the best available version at runtime and loads it into a function
pointer; the function in question is then always called through this pointer.
The specific syntax used for writing assembly is:
@itemize @bullet
@item
NASM on x86;
@item
GAS on ARM and RISC-V.
@end itemize
A unit testing framework for assembly called @code{checkasm} lives under
@file{tests/checkasm}. All new assembly should come with @code{checkasm} tests;
adding tests for existing assembly that lacks them is also strongly encouraged.
@subsection Other languages
Other languages than C may be used in special cases:
@itemize @bullet
@item
Compiler intrinsics or inline assembly when the code in question cannot be
written in the standard way described in the @ref{SIMD/DSP} section. This
typically applies to code that needs to be inlined.

@section Naming conventions
@section C language features
Names of functions, variables, and struct members must be lowercase, using
underscores (_) to separate words. For example, @samp{avfilter_get_video_buffer}
is an acceptable function name and @samp{AVFilterGetVideo} is not.
FFmpeg is programmed in the ISO C90 language with a few additional
features from ISO C99, namely:
Struct, union, enum, and typedeffed type names must use CamelCase. All structs
and unions should be typedeffed to the same name as the struct/union tag, e.g.
@code{typedef struct AVFoo @{ ... @} AVFoo;}. Enums are typically not
typedeffed.
Enumeration constants and macros must be UPPERCASE, except for macros
masquerading as functions, which should use the function naming convention.
All identifiers in the libraries should be namespaced as follows:
@itemize @bullet
@item
No namespacing for identifiers with file and lower scope (e.g. local variables,
static functions), and struct and union members,
the @samp{inline} keyword;
@item
The @code{ff_} prefix must be used for variables and functions visible outside
of file scope, but only used internally within a single library, e.g.
@samp{ff_w64_demuxer}. This prevents name collisions when FFmpeg is statically
linked.
@samp{//} comments;
@item
designated struct initializers (@samp{struct s x = @{ .i = 17 @};});
@item
compound literals (@samp{x = (struct s) @{ 17, 23 @};}).
@item
for loops with variable definition (@samp{for (int i = 0; i < 8; i++)});
@item
Variadic macros (@samp{#define ARRAY(nb, ...) (int[nb + 1])@{ nb, __VA_ARGS__ @}});
@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
@section 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_report_missing_feature}.
@item
All other internal identifiers, like private type or macro names, should be
namespaced only to avoid possible internal conflicts. E.g. @code{H264_NAL_SPS}
vs. @code{HEVC_NAL_SPS}.
@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.
@item
Other public identifiers (struct, union, enum, macro, type names) must use their
library's public prefix (@code{AV}, @code{Sws}, or @code{Swr}).
Note that some symbols without these prefixes are also exported for
retro-compatibility reasons. These exceptions are declared in the

Our libraries may be called by multiple independent callers in the same process.
These calls may happen from any number of threads and the different call sites
may not be aware of each other - e.g. a user program may be calling our
libraries directly, and use one or more libraries that also call our libraries.
The code must behave correctly under such conditions.
@subheading Robustness
The code must treat as untrusted any bytestream received from a caller or read
from a file, network, etc. It must not misbehave when arbitrary data is sent to
it - typically it should print an error message and return
@code{AVERROR_INVALIDDATA} on encountering invalid input data.
@subheading Memory allocation
The code must use the @code{av_malloc()} family of functions from
@file{libavutil/mem.h} to perform all memory allocation, except in special cases
(e.g. when interacting with an external library that requires a specific
allocator to be used).
All allocations should be checked and @code{AVERROR(ENOMEM)} returned on
failure. A common mistake is that error paths leak memory - make sure that does
not happen.

@section Library public interfaces
Every library in FFmpeg provides a set of public APIs in its installed headers,
which are those listed in the variable @code{HEADERS} in that library's
@file{Makefile}. All identifiers defined in those headers (except for those
explicitly documented otherwise), and corresponding symbols exported from
compiled shared or static libraries are considered public interfaces and must
comply with the API and ABI compatibility rules described in this section.
Public APIs must be backward compatible within a given major version. I.e. any
valid user code that compiles and works with a given library version must still
compile and work with any later version, as long as the major version number is
unchanged. "Valid user code" here means code that is calling our APIs in a
documented and/or intended manner and is not relying on any undefined behavior.
Incrementing the major version may break backward compatibility, but only to the
extent described in @ref{Major version bumps}.
We also guarantee backward ABI compatibility for shared and static libraries.
I.e. it should be possible to replace a shared or static build of our library
with a build of any later version (re-linking the user binary in the static
case) without breaking any valid user binaries, as long as the major version
number remains unchanged.
@subsection Adding new interfaces
Any new public identifiers in installed headers are considered new API - this
includes new functions, structs, macros, enum values, typedefs, new fields in
existing structs, new installed headers, etc. Consider the following
guidelines when adding new APIs.
@subsubheading Motivation
While new APIs can be added relatively easily, changing or removing them is much
harder due to abovementioned compatibility requirements. You should then
consider carefully whether the functionality you are adding really needs to be
exposed to our callers as new public API.
Your new API should have at least one well-established use case outside of the
library that cannot be easily achieved with existing APIs. Every library in
FFmpeg also has a defined scope - your new API must fit within it.
@subsubheading Replacing existing APIs
If your new API is replacing an existing one, it should be strictly superior to
it, so that the advantages of using the new API outweigh the cost to the
callers of changing their code. After adding the new API you should then
deprecate the old one and schedule it for removal, as described in
@ref{Removing interfaces}.
If you deem an existing API deficient and want to fix it, the preferred approach
in most cases is to add a differently-named replacement and deprecate the
existing API rather than modify it. It is important to make the changes visible
to our callers (e.g. through compile- or run-time deprecation warnings) and make
it clear how to transition to the new API (e.g. in the Doxygen documentation or
on the wiki).
@subsubheading API design
The FFmpeg libraries are used by a variety of callers to perform a wide range of
multimedia-related processing tasks. You should therefore - within reason - try
to design your new API for the broadest feasible set of use cases and avoid
unnecessarily limiting it to a specific type of callers (e.g. just media
playback or just transcoding).
@subsubheading Consistency
Check whether similar APIs already exist in FFmpeg. If they do, try to model
your new addition on them to achieve better overall consistency.
The naming of your new identifiers should follow the @ref{Naming conventions}
and be aligned with other similar APIs, if applicable.
@subsubheading Extensibility
You should also consider how your API might be extended in the future in a
backward-compatible way. If you are adding a new struct @code{AVFoo}, the
standard approach is requiring the caller to always allocate it through a
constructor function, typically named @code{av_foo_alloc()}. This way new fields
may be added to the end of the struct without breaking ABI compatibility.
Typically you will also want a destructor - @code{av_foo_free(AVFoo**)} that
frees the indirectly supplied object (and its contents, if applicable) and
writes @code{NULL} to the supplied pointer, thus eliminating the potential
dangling pointer in the caller's memory.
If you are adding new functions, consider whether it might be desirable to tweak
their behavior in the future - you may want to add a flags argument, even though
it would be unused initially.
@subsubheading Documentation
All new APIs must be documented as Doxygen-formatted comments above the
identifiers you add to the public headers. You should also briefly mention the
change in @file{doc/APIchanges}.
@subsubheading Bump the version
Backward-incompatible API or ABI changes require incrementing (bumping) the
major version number, as described in @ref{Major version bumps}. Major
bumps are significant events that happen on a schedule - so if your change
strictly requires one you should add it under @code{#if} preprocessor guards that
disable it until the next major bump happens.
New APIs that can be added without breaking API or ABI compatibility require
bumping the minor version number.
Incrementing the third (micro) version 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.
@anchor{Removing interfaces}
@subsection Removing interfaces
Due to abovementioned compatibility guarantees, removing APIs is an involved
process that should only be undertaken with good reason. Typically a deficient,
restrictive, or otherwise inadequate API is replaced by a superior one, though
it does at times happen that we remove an API without any replacement (e.g. when
the feature it provides is deemed not worth the maintenance effort, out of scope
of the project, fundamentally flawed, etc.).
The removal has two steps - first the API is deprecated and scheduled for
removal, but remains present and functional. The second step is actually
removing the API - this is described in @ref{Major version bumps}.
To deprecate an API you should signal to our users that they should stop using
it. E.g. if you intend to remove struct members or functions, you should mark
them with @code{attribute_deprecated}. When this cannot be done, it may be
possible to detect the use of the deprecated API at runtime and print a warning
(though take care not to print it too often). You should also document the
deprecation (and the replacement, if applicable) in the relevant Doxygen
documentation block.
Finally, you should define a deprecation guard along the lines of
@code{#define FF_API_<FOO> (LIBAVBAR_VERSION_MAJOR < XX)} (where XX is the major
version in which the API will be removed) in @file{libavbar/version_major.h}
(@file{version.h} in case of @code{libavutil}). Then wrap all uses of the
deprecated API in @code{#if FF_API_<FOO> .... #endif}, so that the code will
automatically get disabled once the major version reaches XX. You can also use
@code{FF_DISABLE_DEPRECATION_WARNINGS} and @code{FF_ENABLE_DEPRECATION_WARNINGS}
to suppress compiler deprecation warnings inside these guards. You should test
that the code compiles and works with the guard macro evaluating to both true
and false.

Skip estimation of input duration when calculated using PTS.

@item duration_probesize @var{integer} (@emph{input})
Set probing size, in bytes, for input duration estimation when it actually requires
an additional probing for PTS at end of file (at present: MPEG-PS and MPEG-TS).
It is aimed at users interested in better durations probing for itself, or indirectly
because using the concat demuxer, for example.
The typical use case is an MPEG-TS CBR with a high bitrate, high video buffering and
ending cleaning with similar PTS for video and audio: in such a scenario, the large
physical gap between the last video packet and the last audio packet makes it necessary
to read many bytes in order to get the video stream duration.
Another use case is where the default probing behaviour only reaches a single video frame which is
not the last one of the stream due to frame reordering, so the duration is not accurate.
Setting this option has a performance impact even for small files because the probing
size is fixed.
Default behaviour is a general purpose trade-off, largely adaptive, but the probing size
will not be extended to get streams durations at all costs.
Must be an integer not lesser than 1, or 0 for default behaviour.

CONTEXT
=======
The FFmpeg project merges all the changes from the Libav project
(https://libav.org) since the origin of the fork (around 2011).
With the exceptions of some commits due to technical/political disagreements or
issues, the changes are merged on a more or less regular schedule (daily for
years thanks to Michael, but more sparse nowadays).
WHY
===
The majority of the active developers believe the project needs to keep this
policy for various reasons.
The most important one is that we don't want our users to have to choose
between two distributors of libraries of the exact same name in order to have a
different set of features and bugfixes. By taking the responsibility of
unifying the two codebases, we allow users to benefit from the changes from the
two teams.
Today, FFmpeg has a much larger user database (we are distributed by every
major distribution), so we consider this mission a priority.
A different approach to the merge could have been to pick the changes we are
interested in and drop most of the cosmetics and other less important changes.
Unfortunately, this makes the following picks much harder, especially since the
Libav project is involved in various deep API changes. As a result, we decide
to virtually take everything done there.
Any Libav developer is of course welcome anytime to contribute directly to the
FFmpeg tree. Of course, we fully understand and are forced to accept that very
few Libav developers are interested in doing so, but we still want to recognize
their work. This leads us to create merge commits for every single one from
Libav. The original commit appears totally unchanged with full authorship in
our history (and the conflict are solved in the merge one). That way, not a
single thing from Libav will be lost in the future in case some reunification
happens, or that project disappears one way or another.
DOWNSIDES
=========
Of course, there are many downsides to this approach.
- It causes a non negligible merge commits pollution. We make sure there are
not several level of merges entangled (we do a 1:1 merge/commit), but it's
still a non-linear history.
- Many duplicated work. For instance, we added libavresample in our tree to
keep compatibility with Libav when our libswresample was already covering the
exact same purpose. The same thing happened for various elements such as the
ProRes support (but differences in features, bugs, licenses, ...). There are
many work to do to unify them, and any help is very much welcome.
- So much manpower from both FFmpeg and Libav is lost because of this mess. We
know it, and we don't know how to fix it. It takes incredible time to do
these merges, so we have even less time to work on things we personally care
about. The bad vibes also do not help with keeping our developers motivated.
- There is a growing technical risk factor with the merges due to the codebase
differing more and more.
MERGE GUIDELINES
================
The following gives developer guidelines on how to proceed when merging Libav commits.
Before starting, you can reduce the risk of errors on merge conflicts by using
a different merge conflict style:
$ git config --global merge.conflictstyle diff3
tools/libav-merge-next-commit is a script to help merging the next commit in
the queue. It assumes a remote named libav. It has two modes: merge, and noop.
The noop mode creates a merge with no change to the HEAD. You can pass a hash
as extra argument to reference a justification (it is common that we already
have the change done in FFmpeg).
Also see tools/murge, you can copy and paste a 3 way conflict into its stdin
and it will display colored diffs. Any arguments to murge (like ones to suppress
whitespace differences) are passed into colordiff.
TODO/FIXME/UNMERGED
===================
Stuff that didn't reach the codebase:
-------------------------------------
- HEVC DSP and x86 MC SIMD improvements from Libav (see https://ffmpeg.org/pipermail/ffmpeg-devel/2015-December/184777.html)
- 1f821750f hevcdsp: split the qpel functions by width instead of by the subpixel fraction
- 818bfe7f0 hevcdsp: split the epel functions by width
- 688417399 hevcdsp: split the pred functions by width
- a853388d2 hevc: change the stride of the MC buffer to be in bytes instead of elements
- 0cef06df0 checkasm: add HEVC MC tests
- e7078e842 hevcdsp: add x86 SIMD for MC
- 7993ec19a hevc: Add hevc_get_pixel_4/8/12/16/24/32/48/64
- use av_cpu_max_align() instead of hardcoding alignment requirements (see https://ffmpeg.org/pipermail/ffmpeg-devel/2017-September/215834.html)
- f44ec22e0 lavc: use av_cpu_max_align() instead of hardcoding alignment requirements
- 4de220d2e frame: allow align=0 (meaning automatic) for av_frame_get_buffer()
- Support recovery from an already present HLS playlist (see 16cb06bb30)
- Remove all output devices (see 8e7e042d41, 8d3db95f20, 6ce13070bd, d46cd24986 and https://ffmpeg.org/pipermail/ffmpeg-devel/2017-September/216904.html)
- avcodec/libaomenc: export the Sequence Header OBU as extradata (See a024c3ce9a)
Collateral damage that needs work locally:
------------------------------------------
- Merge proresenc_anatoliy.c and proresenc_kostya.c
- Fix MIPS AC3 downmix
Extra changes needed to be aligned with Libav:
----------------------------------------------
- Switching our examples to the new encode/decode API (see 67d28f4a0f)
- HEVC IDCT bit depth 12-bit support (Libav added 8 and 10 but doesn't have 12)

Add AV_CODEC_CAP_FRAME_THREADS to the codec capabilities. There will be very little
speed gain at this point but it should work.
Use ff_thread_get_buffer() (or ff_progress_frame_get_buffer()
in case you have inter-frame dependencies and use the ProgressFrame API)
to allocate frame buffers.
If there are inter-frame dependencies, so the codec calls
ff_thread_report/await_progress(), set FF_CODEC_CAP_ALLOCATE_PROGRESS in
AVCodec.caps_internal and use ff_thread_get_buffer() to allocate frames. The
frames must then be freed with ff_thread_release_buffer().
Otherwise decode directly into the user-supplied frames.
Call ff_progress_frame_report() after some part of the current picture has decoded.
Call ff_thread_report_progress() after some part of the current picture has decoded.
A good place to put this is where draw_horiz_band() is called - add this if it isn't
called anywhere, as it's useful too and the implementation is trivial when you're
doing this. Note that draw_edges() needs to be called before reporting progress.
