A bug was found in dav1d <= 1.0.0 where the event flag New Sequence Header would
not be signaled for some samples using delayed random access points.
It has since been fixed, but nonetheless it's best to ensure the AVCodecContext
is filled with parameters when parsing the first frame, regardless of what events
were signaled.
Fixes ticket #9694.

If the svt equivalent option to an avctx AVOption is passed by the user
then it should have priority. The exception are fields like dimensions, bitdepth
and pixel format, which must match what lavc will feed the encoder after init.
This addresses libsvt-av1 issue #1858.

Qsv encoder only support input P010 and nv12 format directly from system
memory. For other format, we need to upload frame to device memory and
input qsv format to encoder. Now add other system memory format support
to qsv encoder.

The init_pool_size is set to be 64 and it is too many.
Use IOSurfQuery to get NumFrameSuggest which is the suggested
number of frame that needed to be allocated when initializing the decoder.
Considering that the hevc_qsv encoder uses the most frame buffer,
async is 4 (default) and max_b_frames is 8 (default) and decoder
may followed by VPP, use NumFrameSuggest + 16 to set init_pool_size.

Since ffmpeg-qsv uses return value to reinit decoder, it doesn't need to
decode header each time. Move qsv_decode_header's position so that
it will be called only if codec needed to be reinitialized.
Rearrange the code of flushing decoder and re-init decoder operation.
Remove the buffer_count and use the got_frame to decide whether the
decoder is drain.

FFmpeg-qsv decoder reinit codec when width and height change, but there
are not only resolution change need to reinit codec. I change it to use
return value from DecodeFrameAsync() to decide whether decoder need to
be reinitialized.

Commit e050959103 implemented passing in
modifiers by using the PRIME_2 memory type, which only exists in v2 of
the library.
To still support v1 of the library, conditionally compile using
VA_CHECK_VERSION() for both the new code and the old code before
the commit.
Note PRIME_2 memory was introduced from VA-API 1.1, so use
VA_CHECK_VERSION(1, 1, 0) instead of VA_CHECK_VERSION(2, 0, 0) (Haihao)

In case the BSF has not been drained before flushing/closing,
the context's next_frame might be set; yet it is not freed
in flush or close. The former only zeroes it (which automatically
causes a leak in case it was set). So do this when closing
and flushing.

Since the switch to the new FIFO API in commit
ea511196a6, the FIFO is always
grown by the amount of data intended to be written into it
even in case the FIFO has enough free space. Fix this by
only growing the FIFO if needed and then only by the amount that is
actually needed.
The allocation errors that resulted from this uncovered another bug:
The context is left in an inconsistent state in case the FIFO can't
be grown, because the FIFO does not contain as much data as the sizes
contained in the PacketDesc list claim. This led to an infinite loop
in output_packet() (called from mpeg_mux_end()).
Fix this by growing the FIFO before adding a new PacketDesc element,
thereby preventing the context from becoming inconsistent.

This is possible, because every given FFCodec has to implement
exactly one of these. Doing so decreases sizeof(FFCodec) and
therefore decreases the size of the binary.
Notice that in case of position-independent code the decrease
is in .data.rel.ro, so that this translates to decreased
memory consumption.

This increases type-safety by avoiding conversions from/through void*.
It also avoids the boilerplate "AVFrame *frame = data;" line
for non-subtitle decoders.

This increases type-safety by avoiding conversions from/through void*.
It also avoids the boilerplate "AVSubtitle *sub = data;" line
for subtitle decoders. Its only downside is that it increases
sizeof(FFCodec), yet this can be more than offset lateron.

On output streams where a multichannel stream needs to be stored as one track
per channel, each track will have a channel layout describing the position of
the channel they contain. For the track with front center, the mov muxer was
using the mov layout "mono" instead of the label for the front center position.
Since our channel layout API considers front center == mono, we need to do some
heuristics. To achieve this, we make sure all audio tracks contain streams with
a single channel, and only one of them is front center. In that case, we write
the front center label instead of signaling mono layout.
