Andreas Cadhalpun	1762a39e09	mss2: only use error correction for matching block counts This fixes a heap-buffer-overflow in ff_er_frame_end when decoding mss2 with coded_width/coded_height larger than width/height. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	8 years ago
Diego Biurrun	15b4f494fc	mss*: Change type of array stride parameters to ptrdiff_t ptrdiff_t is the correct type for array strides and similar.	8 years ago

wm4	f6774f905f	mpegvideo: operate with pointers to AVFrames instead of whole structs The most interesting parts are initialization in ff_MPV_common_init() and uninitialization in ff_MPV_common_end(). ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL checks for Picture.f, because these functions can be called on uninitialized or partially initialized Pictures. NULL pointer checks are added to ff_thread_release_buffer() stub function. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	11 years ago
Anton Khirnov	ebfe622bb1	mpegvideo: drop support for real (non-emulated) edges Several decoders disable those anyway and they are not measurably faster on x86. They might be somewhat faster on other platforms due to missing emu edge SIMD, but the gain is not large enough (and those decoders relevant enough) to justify the added complexity.	11 years ago
Anton Khirnov	66499f34b5	mpegvideo: do not set current_picture_ptr in decoders This code was originally added in `5f1948111a` to h263 to set decoded frame pts to some random numbers (removed in `a1c5cc429d`) and then cargo culted to other decoders. The code is left in h263dec for now, since some part of the decoder (apparently OBMC) relies on the specific previous frame to be reused.	11 years ago
Anton Khirnov	c2f7417eeb	vc1: move MpegEncContext.resync_marker into VC1Context. The field still remains in MpegEncContext because it is used by the mpeg4 decoder.	11 years ago
Anton Khirnov	e9198f61db	mss2: use the AVFrame API properly.	11 years ago
Diego Biurrun	b2bed9325d	cosmetics: Group .name and .long_name together in codec/format declarations	11 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.

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
Anton Khirnov	edfe05ddf1	mss2: return meaningful error codes.	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
Alberto Delmás	802713c4e7	mss2: prevent potential uninitialized reads The alternative to zeroing on init is setting the corrupted flag in all cases where pal_pic is not fully written, at the cost of added complexity. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	12 years ago

Alberto Delmás	ede3d6400d	MSS1 and MSS2: set final pixel format after common stuff has been initialised This way it won't interfere with WMV9 initialisation inside MSS2 decoder and avplay will play it fine. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	12 years ago
