Luca Barbato	090cd06311	vc1: check the source buffer in vc1_mc functions Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	12 years ago
Rémi Denis-Courmont	578ea75a9e	vdpau: remove old-style decoders Signed-off-by: Anton Khirnov <anton@khirnov.net>	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	b412f705b5	vc1dec: Drop old use_ic code from vc1_b_mc 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
Sebastian Sandberg	1fb013a57c	vc1dec: Add support for interlaced B-frames Signed-off-by: Martin Storsjö <martin@martin.st>	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	201412ffec	vc1dec: Factorize picture pointer selection in vc1_mc_4mv_chroma() Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	2412ad1717	vc1dec: Factorize picture pointer selection code Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	19673db34a	vc1dec: Factorize srcU/V offseting 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
Martin Storsjö	a60136ee57	vc1: Remove now unused variables Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	f4fed5a2f9	mpegvideo: Use hpeldsp instead of dsputil for half-pel functions This also converts vc1, since that is mpegvideo-based. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Diego Biurrun	6d97484d72	avcodec: av_log_ask_for_sample() ---> avpriv_request_sample()	12 years ago
Anton Khirnov	759001c534	lavc decoders: work with refcounted frames.	12 years ago
Diego Biurrun	5f401b7b71	Add missing error_resilience includes to files that use ER	12 years ago
Ronald S. Bultje	8d061989dd	lavc: Split out ff_hwaccel_pixfmt_list_420[] over individual codecs Not all hwaccels implement all codecs, so using one single list for multiple such codecs means some codecs will be represented in the list, even though they don't actually handle that codec. Copying specific lists in each codec fixes that. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Diego Biurrun	c242bbd8b6	Remove unnecessary dsputil.h #includes	12 years ago
Anton Khirnov	1d0feb5d1a	mpegvideo: split ff_draw_horiz_band(). Split out dependency on MpegEncContext.	12 years ago

Diego Biurrun	79dad2a932	dsputil: Separate h264chroma	12 years ago
Vladimir Pantelic	77bcb89600	vc1dec: use codec_id instead of codec_tag for VC1IMAGE the rest of the code is using codec_id everywhere already Signed-off-by: Vladimir Pantelic <vladoman@gmail.com> Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	12 years ago
Ronald S. Bultje	baf35bb4bc	dsputil: remove one array dimension from avg_no_rnd_pixels_tab.	12 years ago
Diego Biurrun	88bd7fdc82	Drop DCTELEM typedef It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	12 years ago
Ronald S. Bultje	93af2734ee	lavc: put FF_IDCT_{VP3,H264,CAVS,BINK,EA,WMV2} under FF_API_IDCT. This allows us to get rid of them on the next major bump. All of the above are functionally irrelevant, and most of them are unused, except the vp3 one, which is used wrongly in the bfin arch optimizations.	12 years ago
Vladimir Pantelic	7b8c5b263b	vc1dec: prevent a crash due missing pred_flag parameter Handle pred_flag parameter not given to get_mvdata_interlaced() Signed-off-by: Vladimir Pantelic <vladoman@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Ronald S. Bultje	8c53d39e7f	lavc: introduce VideoDSPContext Move some functions from dsputil. The idea is that videodsp contains functions that are useful for a large and varied set of video decoders. Currently, it contains emulated_edge_mc() and prefetch(). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Diego Biurrun	ba0c898120	cosmetics: Fix dropable --> droppable typo	12 years ago
Anton Khirnov	df9b956751	lavc: fix decode_frame() third parameter semantics for video decoders It's got_frame, not data size	12 years ago
Anton Khirnov	594d4d5df3	lavc: add a wrapper for AVCodecContext.get_buffer(). It will be useful in the upcoming transition to refcounted AVFrames.	12 years ago
Mashiat Sarker Shakkhar	35a35d49d2	Double motion vector range for HPEL interlaced picture in proper place The existing code is not in the right place and it should cover both interlaced frame and field pictures. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago
Mashiat Sarker Shakkhar	eb657ecefd	vc1dec: Set opposite to the correct value for 1REF field pictures Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago
Mashiat Sarker Shakkhar	7cc3c4e1d4	vc1dec: Invoke edge emulation regardless of MV precision for 1-MV chroma This is required due to the way VC-1 handles chroma pull-back which may end up causing negative chroma MV for zero luma MV. Edge emulation needs to be invoked in such cases. This only affects vertical component of chroma motion vector. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago
Mashiat Sarker Shakkhar	88058d9a99	vc1dec: Set chroma reference field from REFFIELD for 1REF field pictures Interlaced field pictures can have one or two reference pictures, signaled by NUMREF syntax element. For single reference pictures, reference picture is determined by REFFIELD syntax element. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago
Mashiat Sarker Shakkhar	7fb35ee931	vc1dec: Use correct spelling of "opposite" Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
