Carl Eugen Hoyos	2c67c65963	Fix h264 decoding on SSE2 cores with icc compilation. Originally committed as revision 16373 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Jason Garrett-Glaser	c1fc70362f	Fix compilation without optimization under 64-bit with x264 deblock asm enabled. Originally committed as revision 16313 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
Diego Biurrun	ebb160a0b0	Use ARCH_X86_32 instead of !ARCH_X86_64, it is more straightforward. Originally committed as revision 16262 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Jason Garrett-Glaser	a22eff36f9	Port x264 deblocking code to libavcodec. This includes SSE2 luma deblocking code and both MMXEXT and SSE2 luma intra deblocking code for H.264 decoding. This assembly is available under --enable-gpl and speeds decoding of Cathedral by 7%. Originally committed as revision 16239 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
Aurelien Jacobs	5e6604490a	avoid POSIX reserved _t suffix Originally committed as revision 16117 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Loren Merritt	5fecfb7d58	clear_block mmx Originally committed as revision 16045 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	9686df2be5	Delete unnecessary 'extern' keywords. Originally committed as revision 15990 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Dominik Mierzejewski	82d1605fe7	Remove duplicated MM_* macros for CPU capabilities from dsputil.h. Add missing one for FF_MM_ALTIVEC to avcodec.h. Rename all the occurences of MM_* to the corresponding FF_MM_*. Originally committed as revision 15770 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Pettenò	782fc0c36f	Rename template included sources from .h to _template.c. There are multiple source files that are #include'd rather than compiled, as they are used as template for generation of similar code, like asm-optimised code. Some of these files are right now named with a .h extension, although they are not header in any reasonable sense. Rename them so that instead of being named with .h extension they are named with _template.c as final part. Originally committed as revision 15730 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	31c4f07017	Use x86_reg type instead of long in float_to_int16 MMX/SSE functions. Fixes compilation on MinGW64. Originally committed as revision 15655 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

David Conrad	357f45d9bc	MMX VP3 Loop Filter Originally committed as revision 15630 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
David Conrad	8cfd78ce8f	Ensure MMX/SSE2 VP3 IDCT selection isn't disabled when only Theora is enabled Originally committed as revision 15350 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
