AgeCommit message (Collapse)Author
2008-12-22Rename libavcodec/i386/ --> libavcodec/x86/.Diego Biurrun
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
2008-12-22Use ARCH_X86_32 instead of !ARCH_X86_64, it is more straightforward.Diego Biurrun
Originally committed as revision 16262 to svn://svn.ffmpeg.org/ffmpeg/trunk
2008-12-19Port x264 deblocking code to libavcodec.Jason Garrett-Glaser
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
2008-12-18H.264 idct functions that include the chroma, inter luma and intra16 luma loopsMichael Niedermayer
thus avoiding the calling overhead. New functions are not yet used. Originally committed as revision 16206 to svn://svn.ffmpeg.org/ffmpeg/trunk

2008-12-03Delete unnecessary 'extern' keywords.Diego Biurrun
Originally committed as revision 15990 to svn://svn.ffmpeg.org/ffmpeg/trunk
2008-11-03Remove duplicated MM_* macros for CPU capabilities from dsputil.h.Dominik Mierzejewski
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
2008-10-27Rename template included sources from .h to _template.c.Diego Pettenò
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
2008-10-20Use x86_reg type instead of long in float_to_int16 MMX/SSE functions.Reimar Döffinger

Originally committed as revision 15630 to svn://svn.ffmpeg.org/ffmpeg/trunk
2008-10-16Convert asm keyword into __asm__.Diego Pettenò
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
