* avformat/avc: Add functions to split access unit into list of NALUsAndreas Rheinhardt2022-01-191-3/+37
| | | | | | | | This will allow to avoid the temporary buffer and memcpys when repacketing annex B to mp4-style H.264/H.265 without searching twice for start codes. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/avc, mxfenc: Avoid allocation of H264 SPS structure, fix memleakAndreas Rheinhardt2020-06-261-15/+12
| | | | | | | | | | | | | | | | | | | | | | Up until now, ff_avc_decode_sps would parse a SPS and return some properties from it in a freshly allocated structure. Yet said structure is very small and completely internal to libavformat, so there is no reason to use the heap for it. This commit therefore changes the function to return an int and to modify a caller-provided structure. This will also allow ff_avc_decode_sps to return better error codes in the future. It also fixes a memleak in mxfenc: If a packet contained multiple SPS, only the SPS structure belonging to the last SPS would be freed, the other ones would leak when the pointer is overwritten to point to the new SPS structure. Of course, without allocations there are no leaks. This is Coverity issue #1445194. Furthermore, the SPS structure has been renamed from H264SequenceParameterSet to H264SPS in order to avoid overlong lines.

* avformat/av1, avc, hevc: Remove av_freep()Andreas Rheinhardt2020-01-261-2/+1
| | | | | | | | | | | | | | | 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.

* avformat/avc: Avoid allocation for small SPS/PPS arraysAndreas Rheinhardt2019-11-281-9/+6
| | | | | | | | 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>
