Alexander Strange	2b9969a945	H264: Fix out of bounds reads in SSSE3 MC Reading above src[-2] isn't safe, so move loads and palignr ahead 3 pixels to load starting at the first pixel actually used. Fixes issue941. Originally committed as revision 18999 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
David Conrad	8013da7364	VC1: add and use avg_no_rnd chroma MC functions Originally committed as revision 18518 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Baptiste Coudurier	353f87b8d4	fix typo in h264dsp_mmx (no effect currently as the function is not used), approved by Dark Shikari on IRC Originally committed as revision 17046 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Aurelien Jacobs	b250f9c66d	Change semantic of CONFIG_, HAVE_ and ARCH_*. They are now always defined to either 0 or 1. Originally committed as revision 16590 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Mathieu Velten	21ff7689da	Use H264 MMX chroma functions to accelerate RV40 decoding. Patch by Mathieu Velten (matmaul A gmail) Originally committed as revision 16419 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Jason Garrett-Glaser	37fed10087	Add x264 SSE2 iDCT functions to H.264 decoder. Originally committed as revision 16409 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	a6493a8fbd	Rename libavcodec/i386/ --> libavcodec/x86/. It contains optimizations that are not specific to i386 and libavutil uses this naming scheme already. Originally committed as revision 16270 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Michael Niedermayer	ac22385931	H.264 idct functions that include the chroma, inter luma and intra16 luma loops thus avoiding the calling overhead. New functions are not yet used. Originally committed as revision 16206 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Pettenò	be449fca79	Convert asm keyword into __asm__. Neither the asm() nor the __asm__() keyword is part of the C99 standard, but while GCC accepts the former in C89 syntax, it is not accepted in C99 unless GNU extensions are turned on (with -fasm). The latter form is accepted in any syntax as an extension (without requiring further command-line options). Sun Studio C99 compiler also does not accept asm() while accepting __asm__(), albeit reporting warnings that it's not valid C99 syntax. Originally committed as revision 15627 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Michael Niedermayer	4f20b45fbe	Fix h264_loop_filter_strength_mmx2() so it works with PAFF. fixed at least: CVFI1_Sony_D.jsv CVFI1_SVA_C.264 MR6_BT_B.h264 Originally committed as revision 14310 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Ramiro Polla	40d0e665d0	Do not misuse long as the size of a register in x86. typedef x86_reg as the appropriate size and use it instead. Originally committed as revision 13081 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Loren Merritt	1d67b037f7	sse2 h264 motion compensation. not new code, just separate out the cases that didn't need ssse3. Originally committed as revision 11877 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
