In some versions of libsvtav1, setting intra_period_length to 0
does not produce the intended result (i.e.) all frames produced
are not keyframes.
Instead handle the gop_size == 1 as a special case by setting
the pic_type to EB_AV1_KEY_PICTURE when encoding each frame so
that all the output frames are keyframes.
SVT-AV1 Bug: https://gitlab.com/AOMediaCodec/SVT-AV1/-/issues/2076
Example command: ffmpeg -f lavfi -i testsrc=duration=1:size=64x64:rate=30 -c:v libsvtav1 -g 1 -y test.webm
Before: Only first frame is keyframe, rest are intraonly.
After: All frames are keyframes.

Add missing operand which clang complains about but GCC assumes it to be
'm1' if not specified.
Works around build failure with Clang:
| src/libswscale/riscv/rgb2rgb_rvv.S:88:25: error: operand must be e[8|16|32|64|128|256|512|1024],m[1|2|4|8|f2|f4|f8],[ta|tu],[ma|mu]

EOF from sq_receive() means no packets will ever be output by the sync
queue. Since the muxing sync queue is always used by all interleaved
(i.e. non-attachment) streams, this means no further packets can make
it to the muxer and we can terminate muxing now.
Since “2d924b3a63 fftools/ffmpeg: move each muxer to a separate thread”,
opengl_write_packet() is called from a different thread than
opengl_write_header() and would nothing for lack of a selected context.
Mention encoder name in the message to emphasize that the value in
question is not supported by this specific encoder, not necessarily by
libavcodec in general.
Print a list of values supported by the encoder.
Useful for discovering bugs that depend on a specific thread count.
Use like THREADS=randomX for a random thread count from 1 to X, with
X=16 when not specified. Note that the thread count is different for
every test.
That feature is overkill for a constant pointer to AVFilterLink which
can be stored in AVCodecContext.opaque (indirectly, because the link is
not allocated yet at the time the codec is opened).
This also avoids leaking non-NULL AVFrame.opaque to callers.
Git master libjxl changed several function signatures, so this commit
adds some #ifdefs to handle the new signatures without breaking old
releases. Do note that old git master development versions of libjxl
will be broken, but no releases will be.

From the spec: "It is a requirement of bitstream conformance that
the value of luma_bit_depth_entry_minus8 shall be equal to
the value of bit_depth_luma_minus8"; similarly for chroma.
Also fixes Coverity ticket #1529226 (complaining about the fact
that chroma_bit_depth_entry is checked twice).

I don't pretend to understand how we get into this situation, but there
are files out there where we can end up with the active PPS not being
identified when we call vk_hevc_end_frame. In these situations today,
we will segfault. So, before we give up, see if we can get the active
PPS id from the slice header, and use that if possible.
If that still doesn't work, return an error instead of segfaulting.
Should set "number of frames" to bytes 24-27 of IVF header, not
duration.
It is described by [1], and confirmed by parsing all IVF files in [2].
This commit also updates the md5sum of refs to pass fate-cbs.
