Anton Khirnov	eca95dc38f	tests/fate/hevc: add a test for switching between single and multi-view	6 months ago
Anton Khirnov	b15af98f6e	tests/fate/hevc: add a test for nontrivial values of nuh_layer_id Typical files use 0 for the base layer and 1 for the secondary one, but any value for the secondary layer should be supported.	6 months ago
Anton Khirnov	7d4c15cafb	tests/fate/hevc: add MV-HEVC conformance sample tests Only those that can be decoded with our implementation, so excluding * C and D - independent layers * G, H, I - more than 2 layers Frame hashes verified against the reference implementation from https://hevc.hhi.fraunhofer.de/svn/svn_3DVCSoftware/	6 months ago
Anton Khirnov	da420ac6e1	fftools/ffmpeg: add support for multiview video This extends the syntax for specifying input streams in -map and complex filtergraph labels, to allow selecting a view by view ID, index, or position. The corresponding decoder is then set up to decode the appropriate view and send frames for that view to the correct filtergraph input(s).	6 months ago
Anton Khirnov	68c198fae2	fftools/ffmpeg_sched: allow decoders to have multiple outputs Will be useful for multilayer video.	6 months ago
James Almer	aef221b22a	avcodec/hevc/refs: export Stereo 3D side data Use the 3D Reference Displays Info SEI message to link a view_id with an eye. Signed-off-by: James Almer <jamrial@gmail.com>	6 months ago
Anton Khirnov	14746871e1	lavc/hevcdec: implement decoding MV-HEVC At most two layers are supported. Aspects of this work were sponsored by Vimeo and Meta.	6 months ago
Anton Khirnov	0fde9c609f	lavc/decode: merge stereo3d information from decoder with packet side data The HEVC decoder will start setting stereoscopic view position (left or right) based on 3D Reference Displays Info SEI message in future commits. This information should be merged with container-derived stereo3D side data.	6 months ago
Anton Khirnov	327080c088	lavc/decode: make sure side data mapping does not produce duplicates Also, deduplicate the code performing the mapping.	6 months ago
Anton Khirnov	bcbe999077	lavc/decode: clear side data in reget_buffer() Otherwise it may accumulate when e.g. global side data is repeatedly copied to the frame with in each subsequent reget_buffer() call.	6 months ago
Anton Khirnov	e19551d165	lavc/decode: do not clear the frame discard flag in ff_decode_frame_props_from_pkt() Only do it in reget_buffer(). The purpose of this clearing this flag is to prevent it for unintentionally persisting across multiple invocations of this function on one frame, however that is only a problem if the frame is not unreffed between uses, which is only the case with reget_buffer(). In other cases the caller may legitimately want to set the discard flag and should have the option of doing so.	6 months ago
Anton Khirnov	75914b5822	lavc/hevc/hevcdec: implement MV-HEVC inter-layer prediction The per-frame reference picture set contains two more lists - INTER_LAYER[01]. Assuming at most two layers, INTER_LAYER1 is always empty, but is added anyway for completeness. When inter-layer prediction is enabled, INTER_LAYER0 for the second-layer frame will contain the base-layer frame from the same access unit, if it exists. The new lists are then used in per-slice reference picture set construction as per F.8.3.4 "Decoding process for reference picture lists construction".	6 months ago
Anton Khirnov	02a9435cb0	lavc/hevcdec: implement slice header parsing for nuh_layer_id>0 Cf. F.7.3.6.1 "General slice segment header syntax"	6 months ago
Anton Khirnov	a811ab74f0	lavc/hevc/parser: only split packets on NALUs with nuh_layer_id=0 A packet should contain a full access unit, which for multilayer video should contain all the layers.	6 months ago
Anton Khirnov	52ce2d2a04	lavc/hevcdec/parse: process NALUs with nuh_layer_id>0 Otherwise parameter sets from extradata with nuh_layer_id>0 would be ignored. Needed for upcoming MV-HEVC support.	6 months ago
Anton Khirnov	81e9afa6c2	lavc/hevc/ps: reindent	6 months ago
Anton Khirnov	7d245866b8	lavc/hevc/ps: implement SPS parsing for nuh_layer_id>0 Cf. F.7.3.2.2 "Sequence parameter set RBSP syntax", which extends normal SPS parsing with special clauses depending on MultiLayerExtSpsFlag.	6 months ago
Anton Khirnov	4359467ad6	lavc/hevc/ps: drop a warning for sps_multilayer_extension_flag SPS multilayer extension contains a single flag that we are free to ignore, no reason to print a warning.	6 months ago
Niklas Haas	7351e067bc	lavc/hevc_ps: parse VPS extension Only implementing what's needed for MV-HEVC with two views. Signed-off-by: Anton Khirnov <anton@khirnov.net>	6 months ago
James Almer	efa9d3deca	avcodec/hevc/sei: add support for 3D Reference Displays Information SEI Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>	6 months ago
