Mark Thompson	da6db843b8	cbs_h2645: Allocate all internal buffers with padding Any of these buffers (for both H.264 and H.265) might reasonably be parsed using the bitstream reader, so include padding on all of them.	6 years ago
Mark Thompson	3143fe34f6	cbs_h264: Actually decompose end-of-sequence NAL units `64c50c0e97` declared support for decomposing them but omitted to implement it; this adds an implementation. Also do the same for end-of-stream NAL units, since they are equivalent.	6 years ago
Aman Gupta	64c50c0e97	avcodec/cbs_h264: silence errors about end_of_seq nalus [ffmpeg] AVBSFContext: Decomposition unimplemented for unit 4 (type 10). Signed-off-by: Aman Gupta <aman@tmm1.net>	6 years ago
Mark Thompson	ac687add84	cbs_h264: Add support for mastering display SEI messages	7 years ago
Mark Thompson	d94dda742c	cbs_h264: Add support for pan-scan rectangle SEI messages	7 years ago
Haihao Xiang	2943dd35b7	cbs_h265: read/write content light level information SEI message Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>	7 years ago
Haihao Xiang	56ed011692	cbs_h265: read/write HEVC PREFIX SEI Similar to H264, cbs_h265_{read, write}_nal_unit() can handle HEVC prefix SEI NAL units. Currently mastering display colour volume SEI message is added only, we may add more SEI message if needed later Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>	7 years ago
James Almer	c6a63e1109	avcodec/cbs_h2645: use AVBufferRef to store list of active parameter sets Removes unnecessary data copies, and partially fixes potential issues with dangling references held in said lists. Reviewed-by: Mark Thompson <sw@jkqxz.net> Signed-off-by: James Almer <jamrial@gmail.com>	7 years ago
Mark Thompson	300ef25314	cbs: Add support for array subscripts in trace output This makes the trace output for arrays significantly nicer.	7 years ago
Mark Thompson	315cc8c098	cbs_h2645: Simplify representation of fixed values	7 years ago
James Almer	0807a77160	avcodec/cbs_h2645: create a reference to the existing buffer when decomposing slice units Reviewed-by: Mark Thompson <sw@jkqxz.net> Signed-off-by: James Almer <jamrial@gmail.com>	7 years ago
James Almer	df3a2ff767	avcodec/cbs: use a reference to the assembled CodedBitstreamFragment buffer when writing packets This saves one malloc + memcpy per packet The CodedBitstreamFragment buffer is padded to follow the requirements of AVPacket.

Mark Thompson	eccc03c8fb	cbs_h264: Add support for filler NAL units	7 years ago
Mark Thompson	7157d95926	cbs_h264: Move slice_group_id array out of PPS structure It's very large, and is only used in some FMO streams.	7 years ago
Mark Thompson	a2ca8ed903	cbs_h264: Add utility functions to insert/delete SEI messages	7 years ago
Mark Thompson	ce5870a3a8	cbs: Refcount all the things! This makes it easier for users of the CBS API to get alloc/free right - all subelements use the buffer API so that it's clear how to free them. It also allows eliding some redundant copies: the packet -> fragment copy disappears after this change if the input packet is refcounted, and more codec-specific cases are now possible (but not included in this patch).	7 years ago
Mark Thompson	0e4c166cdd	cbs_h2645: Remove active ps references when it is replaced	7 years ago
Mark Thompson	1d12a545ce	cbs: Add an explicit type for coded bitstream unit types Also fix conversion specifiers used for the unit type.	7 years ago
Carl Eugen Hoyos	9b79c65ec0	lavu/lavc/lavf/lavfi: Do not use type modifier %zu on Windows MSVCRT.	7 years ago
Mark Thompson	7bf3f38046	cbs: Add padding to slice data allocations These may be read by the bitstream reader, so they should include the necessary padding for overreads.	7 years ago
