Jpeg2000 decoder is decoding in native endian, so let's use the same workaround
as in fate-mxf-probe-applehdr10.

The old layout happened to be a native layout and therefore missed some
recently fixed layout parsing bugs.

If a custom layout is equivalent to a native one, check if it matches one of the
known layout names and print that instead.

This together with adjusting the inclusion define allows for the
build to not fail with latest Vulkan-Headers that contain the
stabilized Vulkan AV1 decoding definitions.
Compilation fails currently as the AV1 header is getting included
via hwcontext_vulkan.h -> <vulkan/vulkan.h> -> vulkan_core.h, which
finally includes vk_video/vulkan_video_codec_av1std.h and the decode
header, leading to the bundled header to never defining anything
due to the inclusion define being the same.
This fix is imperfect, as it leads to additional re-definition
warnings for things such as
VK_STD_VULKAN_VIDEO_CODEC_AV1_DECODE_SPEC_VERSION. , but it is
not clear how to otherwise have the bundled version trump the
actually standardized one for a short-term compilation fix.
Currently, this only affects untagged RGB/XYZ/Gray, which get forced to
their corresponding metadata before entering the filter graph. The main
justification for this change, however, is the planned ability to add
automatic promotion of unspecified yuv to mpeg range yuv.
Notably, this change will never allow accidentally cross-promoting
unspecified to jpeg or to a specific YUV matrix, since that is still
bound by the constraints of YUV range negotiation as set up by
query_formats.
Previously, we produced output with either \r\n or mixed line endings.
This was undesirable unto itself, but also made working with patches affecting
FATE output particularly challenging, especially via the mailing list.
Everything that consumes the SSA/ASS format is line-ending-agnostic,
so \n is selected to simplify git/ML usage in FATE.
Extra \r characters at the end of a packet are dropped. These are always
ignored by the renderer anyway.
The previous assumption that DXV needs to be aligned to 16x16 was
erroneous. 4x4 works just as well, and FATE decoder tests pass for all
texture formats.
On the encoder side, we should reject input that isn't 4x4 aligned,
like the HAP encoder does, and stop aligning to 16x16. This both solves
the uninitialized reads causing current FATE tests to fail and produces
smaller encoded outputs.
With regard to correctness, I've checked the decoding path by encoding a
real-world sample with git master, and decoding it with
ffmpeg -i dxt1-master.mov -c:v rawvideo -f framecrc -
The results are exactly the same between master and this patch.
On the encoding side, I've encoded a real-world sample with both master
and this patch, and decoded both versions with
ffmpeg -i dxt1-{master,patch}.mov -c:v rawvideo -f framecrc -
Under this patch, results for both inputs are exactly the same.
In other words, the extra padding gained by 16x16 alignment over 4x4
alignment has no impact on decoded video.

This makes all ff_draw_* based filters aware of YUV colorspaces and
ranges. Needed for YUVJ removal. Also fixes a bug where e.g. vf_pad
would generate a limited range background even after conversion to
full-scale grayscale.
The FATE changes were a consequence of the aforementioned bugfix - the
gray scale files are output as full range (due to conversion by
libswscale, which hard-codes gray = full), and appropriately tagged as
such, but before this change the padded version incorrectly used
a limited range (16) black background for these formats.
Use 8 packets/frames by default rather than 1, which seems to provide
better throughput.
Allow -thread_queue_size to set the muxer queue size manually again.

This is the 64bit version of Chris Doty-Humphreys SFC64
Compared to the LCGs these produce much better quality numbers.
Compared to LFGs this needs less state. (our LFG has 224 byte
state for its 32bit version) this has 32byte state
Also the initialization for our LFG is slower.
This is also much faster than KISS or PCG.
This commit replaces the broken LCG used before.
(broken as it had only a period ~200M due to being put in a double)
This changes the output from random() which is why libswresample.mak

Parse iprp and iinf boxes and its child boxes to get the actual codec used
(AV1 for avif, HEVC for heic), and properly export extradata and other
properties in a generic way.
The avif tests reference files are updated as the extradata is now exported.

They are similar to AVIF images (both use the HEIF container).
The only additional work needed is to parse the hvcC box and put
it in the extradata.
With this patch applied, ffmpeg (when built with an HEVC decoder)
is able to decode the files in

Motivated by YUVJ removal. This change will allow full negotiation
between color ranges and matrices as needed. By default, all ranges and
matrices are marked as supported.
Because grayscale formats are currently handled very inconsistently (and
in particular, assumed as forced full-range by swscale), we exclude them
from negotiation altogether for the time being, to get this API merged.
After filter negotiation is available, we can relax the
grayscale-is-forced-jpeg restriction again, when it will be more
feasible to do so without breaking a million test cases.
Note that this commit updates one FATE test as a consequence of the
sanity fallback for non-YUV formats. In particular, the test case now
writes rgb24(pc, gbr/unspecified/unspecified) to the matroska file,
instead of rgb24(unspecified/unspecified/unspecified) as before.
During a resampling operation where
1) user has specified first_pts
2) SWR_FLAG_RESAMPLE is not set initially (directly or otherwise)
3) first_pts has been fulfilled (always using hard compensation)
then upon first encountering a delay where a soft compensation is
required, swr_set_compensation will lead to another init of swr which
will reset outpts to the specified firstpts thus leading to an output
frame having its pts = firstpts. When the next input frame is received,
swr will see a large delay and inject silence from firstpts to the
current frame's pts. This can lead to severe desync and in worst case,
loss of audio playback.
Parameter firstpts initialized to AV_NOPTS_VALUE in swr_alloc and then
checked in swr_init to avoid resetting outpts, thus avoiding reapplication
of firstpts.
Fixes#4131.
This test verifies the parser's handling of multiframe JXL files that
have an entropy-encoded permuted table of contents for each frame. The
testcase is actually six JXL codestreams concatenated together, and the
parser needs to be able to find the boundaries.

- Fixes YA formats, because previous code always assumed alpha as the 4th
component.
- Fixes PAL format (as long as 0 is black, as in a systematic palette), because
previous code assumed it as limited Y.
- Fixes XYZ format because it does not need nonzero chroma components
- Fixes xv30be as the bitstream mode got merged to the non-bitstream mode.

Change the main loop and every component (demuxers, decoders, filters,
encoders, muxers) to use the previously added transcode scheduler. Every
instance of every such component was already running in a separate
thread, but now they can actually run in parallel.
Changes the results of ffmpeg-fix_sub_duration_heartbeat - tested by
JEEB to be more correct and deterministic.
Avoid making decisions based on current graph input state, which makes
the output dependent on the order in which the frames from different
inputs are interleaved.
Makes the output of fate-filter-overlay-dvdsub-2397 more correct - the
subtitle appears two frames later, which is closer to its PTS as stored
in the file.
For fate-h264_mp4toannexb_ticket5927 and
fate-h264_mp4toannexb_ticket5927_2, they work by accident
previously. The sample file has two 'avc1' entries, and video
samples use the second one. It means packets should be decoded with
new extradata in side data. Before this patch, only extradata was
kept in the output, new extradata has been dropped. The output can
be decoded because the two extradata are almost the same, except
level indication. This patch fixed the issue, and add another
fate test.

Current code tracks min/max pts for each stream separately; then when
the file ends it combines them with last frame's duration to compute the
total duration of each stream; finally it selects the longest of those
durations as the file duration.
This is incorrect - the total file duration is the largest timestamp
difference between any frames, regardless of the stream.
Also change the way the last frame information is reported from decoders
to the muxer - previously it would be just the last frame's duration,
now the end timestamp is sent, which is simpler.
Changes the result of the fate-ffmpeg-streamloop-transcode-av test,
where the timestamps are shifted slightly forward. Note that the
matroska demuxer does not return the first audio packet after seeking
(due to buggy interaction betwen the generic code and the demuxer), so
there is a gap in audio.
These are not supported by the drawing functions at all, and were
incorrectly advertised as supported in the past.
Note: This check is added only to separate the logic change from the API
change in the following commit, and will be removed again after it
becomes redundant.
