Andreas Rheinhardt 2899995a6f avformat/av1, avc, hevc: Remove av_freep()
ff_av1_filter_obus_buf() and ff_avc_parse_nal_units_buf() both have a
pointer-to-pointer parameter which they use to pass a newly allocated
buffer to the caller. And both functions freed what this pointer points to
before overwriting it. But no caller of these functions used this feature,
but some had to initialize the pointer just because of this. So remove
it and update the documentation of ff_av1_filter_obus_buf() wrt this fact.

ff_hevc_annexb2mp4_buf in contrast did not free the pointer. This has been
documented, too.

Andreas Rheinhardt 22ec35a428 avformat/av1, hevc: Make *_buf-functions return 0 on success
The output size is already returned via a pointer argument, so there is
no need to return it via the ordinary return value as well. The
rationale behind this is to not poison the return value on success.
It also unifies the behaviour of the *_buf-functions for AVC, AV1 and
HEVC.

Andreas Rheinhardt 680cd59bb2 avformat/hevc: Fix potential leak in case of ff_hevc_annexb2mp4_buf failure
ff_hevc_annexb2mp4_buf() could indicate an error, yet leave cleaning
after itself to the caller, so that a caller could not simply return the
error, but had to free the buffer first.

(Given that all current callers have set filter_ps = 0, this error can
currently not be triggered.)

Tim Walker 34bbc81de8 lavf: simplify ff_hevc_annexb2mp4_buf
Use ff_hevc_annexb2mp4 instead of duplicating
its functionality, and update the documentation
to match the new behavior.
