At the end of its decode function, the decoder sets *got_frame to 1 and
then checks whether ret is < 0; if so, it is returned, otherwise
avpkt->size is. But it is impossible for ret to be < 0 here and if it
were, it would be nonsense to set *got_frame to 1 before this. Therefore
just return avpkt->size unconditionally.
Fixes Coverity issue #1439730.

This ensures no queued timestamps or side data are kept and used after
seeking, preventing potential desyncs.

Without this metadata section the ffmpeg utility thinks that the AMF encoder
does not support input from D3D11 and DXVA2 hardware surfaces, causing
hardware pipelines to fail.
Fixes#8953.
Is incorrect behaviour. Was covering for an encoder bug where it produced frames
of the wrong size.
This reverts commit e9dd73d30d.

During init the mts2 decoder allocates several VLCs and then several
buffers in a loop; if one of the latter allocations fails, only the VLCs
are freed, not any buffers that might already have been successfully
allocated. This commit fixes this by setting the
FF_CODEC_CAP_INIT_CLEANUP flag.

It simplifies freeing them and reduces the amount of allocations.

The Canopus Lossless decoder uses several VLCs and if initializing the
ith VLC fails, all the VLCs 0..i have been freed; the ith VLC's table is
initialized to NULL for this purpose. Yet it is totally unnecessary to
free the ith VLC table at all: ff_init_vlc_sparse() cleans up after
itself on error and if an error happens before ff_init_vlc_sparse(),
the ith VLC hasn't been touched yet and doesn't need freeing.

It's only used in the codec2 demuxers, and can be simplified with an AV_RB16()
call instead.

Partially implements setup_past_independence() and load_previous().
These ensures they are always set, even if the values were not coded
in the input bitstream and will not be coded in the output bitstream.

This function is so extremely simple that it is preferable to make it
inline rather than deal with all the complications arising from it being
an exported symbol.
Keep avpriv_align_put_bits() around until the next major bump to
preserve ABI compatibility.
Allocating one temporary entry more than needed was made necessary by
the COPY loop below writing an element before having checked that it
should be written at all. But given that this behaviour changed, the
need for overallocating is gone.

For poc 2, we have tile boundary at x = 640.
When we predict cu(640,912),the top left pixel is not avaliable to the cu.
So, we can not check it's intra or not. We need set top[-1] = top[0] directly.
