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

Michael Niedermayer	058e1f8dd7	vc1dec: odd sized sprites are unsupported It should be easy to add support but without a sample we would not know if they work. Fixes out of array reads Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Anton Khirnov	54974c6298	error_resilience: decouple ER from MpegEncContext	12 years ago
Michael Niedermayer	0d194ee51e	vc1dec: Fix 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: Michael Niedermayer <michaelni@gmx.at>	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

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().

Michael Niedermayer	3a04c18d89	vc1dec: prevent null ptr dereferences. The added checks are in line with existing checks but should probably be replaced by more advanced error concealment at some point.
