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
5bda4ec6c3

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.

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.
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.
When intra_refresh is enabled, gopLength is equal to
NVENC_INFINITE_GOPLENGTH. gopLength should be 1 at least.

Changes the result of fate-mxf-probe-dv25, where the bitrate is now
exported.
Also changes the result of fate-bsf-dv-error-marker, where the exported
bitrate is now different. Note that the codec layer bitrate does not
match the container bitrate, because container timing is 25fps, while
the DV profile is 50.
This way decoding errors will not be returned when the user starts
draining the decoder, avoiding confusion over whether draining did or
did not start.
Fixes failures of fate-h264-attachment-631 for certain numbers of frame
threads (e.g. 5).
Do it from ff_decode_get_packet() rather than from
avcodec_send_packet(). This way all nontrivial stages of the decoding
pipeline (i.e. other than just placing a packet at its entrance) are
pull-based rather than a mix of push an pull.
Decoding pipeline has multiple stages, some of which may have their own
delay (e.g. bitstream filters). The code currently uses
AVCodecInternal.draining to track all of them, but they do not have to
all be in sync.
The goal is to distinguish between APIs provided by the generic layer to
individual codecs and APIs internal to the generic layer.
Start by moving ff_{decode,encode}_receive_frame() and
ff_{decode,encode}_preinit() into this new header, as those functions
are called from generic code and should not be visible to individual
codecs.
