Error submitting a frame for encoding
After:
All 150 encoded frames match
The logic did not follow the documented behaviour and that caused skipping of
some audio in the loop and in the leftover buffer.
Example command line which should produce a smooth sine wave for the whole
duration of the output:
ffmpeg -f lavfi -i "sine=r=48000:f=480:d=4" -af "aloop=loop=4:start=48000:size=48000" out.wav
Fixes ticket #11283.

If the audio loop stops inside an audio frame, the leftover buffer contains the
end of the frame, which is not looped. The length supposed to be the part which
was not written to the loop buffer, so we need to drain exactly that number of
bytes from the leftover buffer.

And ensure the buffer is synced between threads.

This removes the ABI breaking use of sizeof(AVFilmGrainParams), and achieves the
same size reduction to decoder structs as 08b1bffa49.

AVFilmGrainAFGS1Params, the offending struct, is using sizeof(AVFilmGrainParams)
when it should not. This change also forgot to make the necessary changes to the
frame threading sync code.
Both of these will be fixed by the following commit.
H274FilmGrainDatabase will be handled later.
This reverts commit 08b1bffa49.

This commit introduced a regression to VVC_HDR_UHDTV1_OpenGOP_3840x2160_50fps_HLG10_mosaic.ts.
Root Cause:
The AV_CEIL_RSHIFT(a, b) macro uses bit tricks that work only when -a is a negative value.
However, due to integer promotion rules, this behavior does not extend to the unsigned int type.
See "6.3.1.1 Boolean, characters, and integers" in the "ISO/IEC 9899" for details.

Pointers to specific entries in the array are stored in other structs, so
in the scenario where heif_item was reallocated when parsing an iloc box after
and iinf one, the pointers may end up referencing freed memory.
Fixes use-after-free with such samples.

Setting it was broken in 8160178dfc, since
links are not yet set up during init. It is also redundant, as the
struct also stores the input index.

When Closed Captions are discovered, this method is always invoked.
Therefore, use it to set the property instead of repeating the statement.
