Ronald S. Bultje	458446acfa	lavc: Edge emulation with dst/src linesize Allow supporting files for which the image stride is smaller than the maximum 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

Luca Barbato	14ddbb477f	cavs: K&R formatting cosmetics	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
Martin Storsjö	9e0f14f16c	lavc: Make pointers to ff_cropTbl const There's no point in these pointers not being const. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Diego Biurrun	79dad2a932	dsputil: Separate h264chroma	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
Anton Khirnov	7d84826400	cavs: deMpegEncContextize It does not use any of the mpegvideo infrastructure, just a few fields from the context. Fixes a segfault with the emu edge flag, since emu edge buffer is now allocated as a part of the frame buffer allocation and cavs calls ff_get_buffer() directly, it does not use mpegvideo buffer management. Fixes a memleak of the last frame.	12 years ago
Anton Khirnov	64bb3fa6b7	cavs: cosmetics, reformat top part	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().

Aneesh Dogra	c265b77b11	cavs: Remove unused code. The square is always passed as 1 whenever the function is called and thus the if block never gets executed. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Michael Niedermayer	280beebd39	cavsdec: initialize all tables to zeros. This ensures that they dont contain invalid values. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
