* avformat/avc, mxfenc: Avoid allocation of H264 SPS structure, fix memleakAndreas Rheinhardt2020-06-26
| | | | | | | | | | | | | | | | | | | | | | 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.

Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk
