Ronald S. Bultje	93f305473f	lavc: Convert some remaining strides to ptrdiff_t	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
Ronald S. Bultje	c341f734e5	Convert multiplier for MV from int to ptrdiff_t. This prevents emulated_edge_mc from not undoing mvy*stride-related integer overflows. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 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

Anton Khirnov	759001c534	lavc decoders: work with refcounted frames.	12 years ago
Anton Khirnov	6e7b50b427	mpegvideo_enc: drop support for reusing the input motion vectors. This misfeature is most likely completely useless and conflicts with removing the mpegvideo-specific fields from AVFrame. In the improbable case it is actually useful, it should be reimplemented in a better way.	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	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().

Janne Grunau	f1d8763a02	mpegvideo: allocate scratch buffers after linesize is known Since we can't know which stride a custom get_buffer() implementation is going to use we have to allocate this scratch buffers after the linesize is known. It was pretty safe for 8 bit per pixel pixel formats since we always allocated memory for up to 16 bits per pixel. It broke hoever with cmdutis.c's alloc_buffer() and high pixel bit depth since it allocated larger edges than mpegvideo expected. Fixes fuzzed sample nasa-8s2.ts_s244342.	12 years ago
