Hi Michael,
I do not mind spending most of the time myself. I just need a person
to go to when I have doubts. I really do not mind doing it without it
being through GSoC either. Just wanted to try contributing to the
organization. I was thinking about starting by fixing tickets #4601 or
#4610. Wou

Chromium fuzzers have caught places where uninitialized data was used due
to calls to avio_read() not verifying that the number of bytes expected was
actually read. So updating the code to check the result from avio_read().

The specifications are de-facto frozen now as they've already been used in
production for years now, the author has indicated reluctance on IRC to change
it further, and the only potential changes would, from what I understand, be
forward-compatible.

Those SEIs refer to the currently active SPS. However, since the SEI
NALUs precede the coded picture data in the bitstream, the active SPS is
in general not known when we are decoding the SEI.
Therefore, store the content of the picture timing SEIs and actually
parse it when the active SPS is know

Default to enable uniform_spacing_flag. Guess level by the tile
rows/cols. Supported for ICL+ platforms.
Also add documentations.
To encode with 4 rows 2 columns:
ffmpeg ... -c:v hevc_vaapi -tile_rows 4 -tile_cols 2 ...

Add functions to initialize tile slice structure and make tile slice:
- vaapi_encode_init_tile_slice_structure
- vaapi_encode_make_tile_slice
Tile slice is not allowed to cross the boundary of a tile due to
the constraints of media-driver. Currently adding support for one
slice per tile.
N x N
Wrap current whole-row slice codes into following functions:
- vaapi_encode_make_row_slice()
- vaapi_encode_init_row_slice_structure()
