A new codec ID has been added to avcodec for animated JPEG XL, so
we should use that in the animated JPEG XL demuxer.

Layouts with both pairs (7.1, 7.1.2, etc) in IAMF that follow the definition in
ITU-R BS.2051-3 for Systems I and J also follow its ordering. This means side
comes before back, which is the inverse of how it's defined in AVChannel.
To workaround this without having to use custom order channel layouts, swap the
stream ids in the input IAMF structure, so packets for one are mapped to the
other.

The current logic uses 12-bit linear light math, which is woefully insufficient
and leads to nasty postarization artifacts. This patch simply switches the
internal logic to 16-bit precision.
This raises the memory requirement of these tables from 32 kB to 272 kB.
All relevant FATE tests updated for improved accuracy.
Fixes: #4829

We should at least bias towards the nearest integer, instead of always
rounding down, when not dithering. This is a bit more correct.
The FATE changes are only in the cases where sws_dither was explicitly set
to "none", which is exactly as expected.

This code only checks hcScale. In practice this is not an issue because
the function pointers should always be identical to hyScale for the same
filter size.
Add an assertion just to make sure this assumption never regresses.

Currently, ffprobe has two stream-level fields that do not work,
closed_captions and film_grain).
Their value is always 0 because ffprobe cannot access the internal
codec properties when it is setting up its stream contexts.
In this commit, add the new option -analyze_frames to ffprobe,
allowing the user to read frames up to the interval they have defined
and fill these fields based on what is exposed in AVPacketSideData.
Additionally, in the same commit, don't write these fields to
the output unless analyze_frames is enabled. Finally, fix the
FATE test refs accordingly and update the docs.

This fixes occasional failed tests, if doing "make fate" without a
regular "make" or "make all" inbetween.
Signed-off-by: Martin Storsjö <martin@martin.st>
If running tests with "make -j<N> fate", the execution will stop
after the first failing test. To get an overview of the whole
test suite, one rather would run "make -k -j<N> fate", which then
again buries the results about what tests actually failed further
up in the console log.
Add a target so one can run "make fate-list-failing", to see a list
of all tests that failed the last time they were executed.
Also add a companion target "fate-clear-reports" which removes all
the old test reports. (When executing a subset of tests, the report
files of all tests that aren't executed stay untouched. This also
allows getting rid of reports for tests that no longer are present
in the testsuite.)

This corresponds to commit 9278a14cf406f8edb5052c42b83750112bf5b515
in dav1d.
Omitting the C-only functions doesn't speed up benchmarking
anyway (as those has to be benchmarked before we know if we have
any corresponding assembly functions), and being able to benchmark
those functions without corresponding assembly can be valuable in
a number of cases.

Share the checkasm_check_pixel macro from hevc_pel in checkasm.h,
to allow other tests to use the same. (To use it in other tests,
those tests need to have a similar setup for high bitdepth pixels,
with a local variable named "bit_depth".)
This simplifies the code for checking the output, and can print
the failing output (including a map of matching/mismatching
elements) if checkasm is run with the -v/--verbose option.

The PNGv3 Specification Draft [1] has changed the capitalization
of mDCV and cLLI chunks (formerly mDCv and cLLi). This patch updates
FFmpeg to work with the new chunk names while retaining decode-side
compatibility with files created using the old names.

There is an issue with the constants used in YUV to YUV range conversion,
where the upper bound is not respected when converting to mpeg range.
With this commit, the constants are calculated at runtime, depending on
the bit depth. This approach also allows us to more easily understand how
the constants are derived.
For bit depths <= 14, the number of fixed point bits has been set to 14
for all conversions, to simplify the code.
For bit depths > 14, the number of fixed points bits has been raised and
set to 18, to allow for the conversion to be accurate enough for the mpeg
range to be respected.
The convert functions now take the conversion constants (coeff and offset)
as function arguments.
For bit depths <= 14, coeff is unsigned 16-bit and offset is 32-bit.
For bit depths > 14, coeff is unsigned 32-bit and offset is 64-bit.

NOTE: all simd optimizations for range_convert have been disabled.
they will be re-enabled when they are fixed for each architecture.
NOTE2: the same issue still exists in rgb2yuv conversions, which is not
addressed in this commit.
WASI mssing signal and siglongjmp support. This patch workaround
build error and add simd128 flag. Please note that many tests use
large array on stack, so you need to increase the stack size when
build checkasm, e.g., --extra-ldflags='-Wl,-z,stack-size=10485760'
