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
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 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.

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	fa9b873e08	clean up an ugliness introduced in r11826. this syntax will require fewer changes when adding future sse2 code. Originally committed as revision 11868 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Michael Niedermayer	61240ae556	fix chroma mc2 bug, this is based on a patch by (Oleg Metelitsa oleg hitron co kr) and does slow the mc2 chroma put down, avg interrestingly seems unaffected speedwise on duron this of course should be rather done in a way which doesnt slow it down but its better a few % slower but correct then incorrect Originally committed as revision 8093 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
