Previous assertion was not useful. Now a warning is added to replace it.
For get_surface_index, we should return a zero index in case the index is not found.
But a warning is necessary to notify.

Previous max_num_refs was based on pp.frame_refs plus 1 and it could possibly
reaches the size limit. Actually it should be the size of pp.ref_frame_map
plus 1.

hw_frames_ctx on the input link is only set when the input link is
configured, which hasn't happened yet. This temporarily hacks around
the problem (in a way no worse than before the format negotiation
changes) until a proper fix can be applied.
The gcrypt definition of `bn_new` used to use the return statement
on errors, with an AVERROR return value, regardless of the signature
of the function where the macro is used - it is called in
`dh_generate_key` and `ff_dh_init` which return pointers. As a result,
compiling with gcrypt and the ffrtmpcrypt protocol resulted in an
int-conversion warning. GCC 14 may upgrade these to errors [1].
This patch fixes the problem by changing the macro to remove `AVERROR`
and instead set `bn` to null if the allocation fails. This is the
behaviour of all the other `bn_new` implementations and so the result is
already checked at all the callsites. AFAICT, this should be the only
change needed to get ffmpeg off Fedora's naughty list of projects with
warnings which may be upgraded to errors in GCC 14 [2].

VideoToolbox use different identifiers for the same pixel format
with different color range, like
kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange
kCVPixelFormatType_420YpCbCr8BiPlanarFullRange.
Before the patch, vt_pool_alloc() always use limited range, and it
will fail for pixel format AV_PIX_FMT_BGRA since there is no limited
range kCVPixelFormatType_32BGRA.

This patch populates the third entry for HLS codec attribute using the
AAC profile.
The HLS specifications[1] require this value to be the Object Type ID as
referred to in table 1.3 of ISO/IEC 14496-3:2009[2].
The numerical constants in the code refer to these OTIs minus one, as
documented in commit 372597e[3], confirmed by comparing the values in the
code with the values in the table mentioned above.

This is the main entry point for the CTU (Coding Tree Unit) decoder.
The code will divide the CTU decoder into several stages.
It will check the stage dependencies and run the stage decoder.
