It differs from query_func() in accepting arrays of input/output format
configurations to be filled as callback parameters. This allows to mark
the filter context as const, ensuring it is not modified by this
function, as it is not supposed to have any side effects beyond
returning the supported formats.
This ensures that if a codec isn't on codec_whitelist, trying to open it
will not trigger ff_codec_close(), which could invalidate useful
information still present in the context.

The ret value here is not yet intialized so the return would return
uninitialized data. What was probably meant to be checked here was the
return value of ffio_read_size, which can return an error.

Text was stolen from the linux kernel
This is thus identical to the kernel just a different more compact format.
I am very happy also to switch the file entirely to the format of the linux kernel maintainer list
if people prefer
This allows specifying a git repository for an area

This allows specifying a bug tracker. It would allow a maintainer to
use gitlab, github, or something else to keep track of bugs

The output of put_bits_left() here can be as big as 27, which is a bit

Use ff_mp4_read_descr() to read both the tags and the vlc value
that comes after it, which was not being taken into account.

Implement the missing requirements from H.266 (V3) p. 106 on the
position and size of subpictures whose dimensions are provided
explicitly.
Signed-off-by: Frank Plowman <post@frankplowman.com>
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.

Adding level to some of my entries
Adding level to some random entries of other people who i have seen actively maintaining their code
removing some people who have not been active where others where active
For most we will need to contact people and ask if they are still available as maintainers
(but for cases where patches are ignored for many months even with pings sent to the maintainer
entries should be set to unmaintained)
