lavc/vvc: Prevent OOB access in subpic_tiles
...
The previous logic relied on the subpicture boundaries coinciding with
the tile boundaries. Per 6.3.1 of H.266 (V3), vertical subpicture
boundaries are always tile boundaries however the same cannot be said
for horizontal subpicture boundaries. Furthermore, it is possible to
construct an illegal bitstream where vertical subpicture boundaries are
not coincident with tile boundaries. In these cases, the condition of
the while loop would never be satisfied resulting in an OOB read on
col_bd/row_bd.
Patch fixes this issue by replacing != with <, thereby not requiring
subpicture boundaries and tile boundaries to be coincident.

lavc/hevcdec: simplify output logic
...
Current code is written around the "simple" decode API's limitation that
a single input packet (AU/coded frame) triggers the output of at most
one output frame. However the spec contains two cases where a coded
frame may cause multiple frames to be output (cf. C.5.2.2.2):
* start of a new sequence
* overflowing sps_max_dec_pic_buffering
The decoder currently contains rather convoluted logic to handle these
cases:
* decode/output/per-frame sequence counters,
* HEVC_FRAME_FLAG_BUMPING
* ff_hevc_bump_frame()
* special clauses in ff_hevc_output_frame()
However, with the receive_frame() API none of that is necessary, as we
can just output multiple frames at once. Previously added ContainerFifo
allows that to be done in a straightforward and efficient manner.

avcodec/mediacodecdec: call MediaCodec.stop on close
...
Usually the MediaCodec context will be released immediately, or it needs to stay
alive due to existing hardware buffers.
However we can free resources early in the case of
hw_buffer_count == 0 && refcount > 1, which can be reproduced by keeping frames
referenced after flushing and closing. mpv currently behaves like this.
