f291b241a3 swscale/input: Use more unsigned intermediates 
Same principle as previous commit, with sufficiently huge rgb2yuv table
values this produces wrong results and undefined behavior.
The unsigned produces the same incorrect results. That is probably
ok as these cases with huge values seem not to occur in any real
use case.

7268323193 hwcontext_vulkan: remove optional encode/decode extensions from the list 
They're not currently used, so they don't need to be there.
Vulkan stabilized the decode extensions less than a week ago, and their
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.

while the second row contains only G and R samples). They

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
