Andreas Rheinhardt	3ba4f9c21e	avcodec/cbs_sei: Use RefStruct API for SEI messages The SEI message code uses the AVBuffer API for its SEI messages and contained buffers (like the extension buffer for HEVC or the user data (un)registered payload buffers). Contrary to the ordinary CBS code (where some of these contained buffer references are actually references to the provided AVPacket's data so that one can't replace them with the RefStruct API), the CBS SEI code never uses outside buffers at all and can therefore be switched entirely to the RefStruct API. This avoids the overhead inherent in the AVBuffer API (namely the separate allocations etc.). Notice that the refcounting here is actually currently unused; the refcounts are always one (or zero in case of no refcounting); its only advantage is the flexibility provided by custom free functions.

Nuo Mi	dfc62fd1c6	avcodec/cbs: add cbs implementation for H266/VVC Add CodedBitstreamContext to parse VPS,SPS,PPS in VVC nal units. Implement parsing and writing of SPS,PPS,VPS,PH,AUD,SEI and slices. Add ff_cbs_type_h266 to cbs types tables and AV_CODEC_ID_H266 to cbs codec ids. Co-authored-by: Thomas Siedel <thomas.ff@spin-digital.com> Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago
Andreas Rheinhardt	2ba04bafb4	avcodec/cbs: Remove ff_cbs_alloc_unit_content It is no longer used. Also rename ff_cbs_alloc_unit_content2 to ff_cbs_alloc_unit_content. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	2 years ago
Andreas Rheinhardt	70d226575a	avcodec/cbs_sei: Fix leak of AVBufferRef on error An AVBufferRef (and the corresponding AVBuffer and the underlying actual buffer) would leak in ff_cbs_sei_add_message() on error in case an error happened after its creation and before it has been attached to more permanent storage. Fix this by only creating the AVBufferRef immediately before attaching it to its intended target position. (Given that no SEI message currently created is refcounted, the above can't happen at the moment. But Coverity already nevertheless noticed: This commit fixes Coverity issue #1473521.)
