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

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
Anton Khirnov	54974c6298	error_resilience: decouple ER from 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

Kostya Shishkov	7627c35a81	vc1: export some functions This is a preparatory step for the MSS2 decoder which needs to use the WMV9 decoder to decode some kinds of frames. From the patch by Alberto Delmás <adelmas@gmail.com>	12 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	12 years ago
Mashiat Sarker Shakkhar	9cc74c9f6e	vc1dec: Remove separate scaling function for interlaced field MVs The scaling process for obtaining direct MVs from co-located field MVs is the same for interlaced field and progressive pictures. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	12 years ago
Mashiat Sarker Shakkhar	8379ea5e9f	vc1dec: Invoke edge_emulation regardless of MV precision In VC-1 interlaced field pictures, chroma motion vectors can extend beyond picture boundary even if luma vectors are bounded. The problem shows up only for hpel interpolated MVs, and may be due to the way motion vectors are scaled / cropped. Thanks to Konstantin Shishkov for suggesting the fix. This fixes long-known segfaults in MC-VC1.ts from videolan streams archive. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	12 years ago

Mashiat Sarker Shakkhar	082829520e	vc1dec: Do not use random pred_flag if motion vector data is skipped This fixes SA10143.vc1 from test-suite. Also partially fixes MC-VC1.ts from videolan streams archive. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago

Ronald S. Bultje	c742ab4e81	vc1parse: call vc1_init_common(). The parser uses VLC tables initialized in vc1_common_init(), therefore we should call this function on parser init also. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	ae591aeea5	vc1: prevent using last_frame as a reference for I/P first frame. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
