This decoding flag makes decoders drop all frames after a parameter
change, but what exactly constitutes a parameter change is not well
defined and will typically depend on the exact use case.
This functionality then does not belong in libavcodec, but rather in
user code
Copy packet side data to the output frame in ff_decode_frame_props_from_pkt()
instead of in discard_samples(), having the latter only applying the skip if
required.
This will be useful for the following commit.

Prevent the fifo used in encoding VPx videos from filling up and
stopping encode when it reaches 21845 items, which happens when the
video has more than that number of frames.
Incorporated suggestion from James Zern to prevent calling
frame_data_submit() at all when performing the first pass of a 2-pass
encode so the fifo is not filled at all; replaces original patch which
drained the fifo after filling to prevent it from becoming full.
Fixes the regression originally introduced in

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]
| vsetvli t4, t3, e8, ta, ma

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.
