Anton Khirnov	6792559f8a	vc1: use the AVFrame API properly.	11 years ago
Ronald S. Bultje	458446acfa	lavc: Edge emulation with dst/src linesize Allow supporting files for which the image stride is smaller than the maximum block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.	11 years ago
Luca Barbato	08303d7741	hwaccel: Simplify ff_find_hwaccel It is always called by passing fields from an AVCodecContext.	11 years ago
Michael Niedermayer	2c7c2a53b9	vcodec/vc1dec: remove dead code Fixes CID732196 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	1e2ab98460	avcodec/vc1dec: use logical operation instead of bitwise for twomv Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Clément Bœsch	b46f19100b	cosmetics: group remaining .name and .long_name. See `b2bed9325`.	11 years ago
Diego Biurrun	b2bed9325d	cosmetics: Group .name and .long_name together in codec/format declarations	11 years ago
Ronald S. Bultje	face578d56	Rewrite emu_edge functions to have separate src/dst_stride arguments. This allows supporting files for which the image stride is smaller than the max. block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.	11 years ago

Martin Storsjö	5e25fdbfe0	vc1dec: Make sure last_picture is initialized in vc1_decode_skip_blocks Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	b772b0e28e	vc1dec: Undo mpegvideo initialization if unable to allocate tables Previously, s->context_initialized was left set to 1 if ff_vc1_decode_init_alloc_tables failed, skipping the initialization completely on the next decode call. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago

Michael Niedermayer	a0c6c8e53e	Revert "Merge commit of 'vdpau: remove old-style decoders'" This reverts commit `bf36dc50ea`, reversing changes made to `b7fc2693c7`. Conflicts: libavcodec/h264.c Keeping support for the old VDPAU API has been requested by our VDPAU maintainer Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	d8b9dbe776	vc1dec: Fix mixed field/frame intensity compensation Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	17410faa22	vc1dec: Match addressing between compensation and MC in vc1_mc_4mv_chroma4 Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	1be175f929	vc1dec: Handle top and bottom blocks in vc1_mc_4mv_chroma4() differently if needed Now it can use different references for those blocks and even use averaging. This fixes several chroma artifacts in several videos. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	c69765a2cc	vc1dec: Fix doxy for vc1_mc_4mv_chroma4() Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Michael Niedermayer	5053a9a1ff	vc1: Use shuffled use_ic instead of equally shuffled mv_mode Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	3ced06f283	vc1dec: Implement intensity compensation for vc1_interp_mc() Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	28243b0d35	vc1dec: Redesign the intensity compensation Use the intensity-compensated reference frame for subsequent fields/B-frames. Since we currently don't change the reference frame we have to maintain lookup tables for intensity compensation in the following dependent frames. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	93b1281264	vc1dec: Shuffle field MVs after decoding, not before This simplifies the code since copying MVs to the reference is not needed anymore (and maybe something about fixing artifacts). Also remove the unused mv_f_last. Fixes a small number of artifacts in black_screen_VC-1.mkv and several more artifacts in other videos. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	ebe8c7fe52	vc1dec: restructure interpmvp code This fixes a valgrind warning about use of uninitialized stuff (no actual such use occurs though) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	f4cc38e339	vc1dec: silence "may be used uninitialized in this function" warning from gcc Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Martin Storsjö	3ca3709ad4	vc1dec: Remove some now unused variables Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	4162fc62b3	vc1dec: Do not allow field_mode to change after the first header This fixes out of array accesses. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	ec7d002e55	vc1, mss2: Check for any negative return value from ff_vc1_parse_frame_header This is required if we return other error codes than explicitly -1, which so far has been the only other possible return value besides 0. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	ccb148e478	vc1dec: Fix current ptr selection in vc1_mc_4mv_chroma() No sample tried shows a difference. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Michael Niedermayer	012b319d91	vc1dec: Fix tff == 0 handling in init_block_index() This fixes several files from VLC ticket 5887. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	0313653928	vc1dec: Update destination pointers in context for fields This replaces a large number of checks for the second field by fixing the pointers when they are setup. This should also fix I/BI field pictures. Changes checksums for vc1_sa10143, the file becomes slightly closer to what the reference decoder outputs. Based on "vc1dec: the second field is written wrong to the picture" by Sebastian Sandberg <sebastiand.sandberg@gmail.com>. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	5d9d8461fb	vc1dec: Don't apply the loop filter on fields Fixes read of uninitialized memory. Based on a patch by Michael Niedermayer. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	46430fd47c	vc1dec: Don't attempt error concealment on field pictures This is not implemented and doesn't work. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Sebastian Sandberg	1bd57a850a	vc1dec: fieldtx is only valid for interlaced frame pictures The fieldtx_plane is not cleared for interlaced fields. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
