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	c36a3df676	avformat/avc: Avoid allocation for small SPS/PPS arrays By using avio_get_dyn_buf() + ffio_free_dyn_buf() instead of avio_close_dyn_buf() + av_free() one can avoid an allocation + copy for small extradata. Furthermore, it simplifies freeing. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	5 years ago
