* Rename libavcodec/i386/ --> libavcodec/x86/.Diego Biurrun2008-12-22
| | | | | | | 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
* Convert asm keyword into __asm__.Diego Pettenò2008-10-16
| | | | | | | | | | | | | 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.

| | | | | | (patch for plain mmx support is welcome ...) Originally committed as revision 10226 to svn://svn.ffmpeg.org/ffmpeg/trunk

* update mmx code to latest snow changesMichael Niedermayer2007-08-25
| | | | | | | note, the code likely can overflow and thus needs some more changes sse2 updated too but disabled as it is untested Originally committed as revision 10223 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Change rounding of the horizontal DWT to match the vertical one.Michael Niedermayer2007-08-21
| | | | | | | This allows some simplifications and optimizations and should not have any effect on quality. Originally committed as revision 10172 to svn://svn.ffmpeg.org/ffmpeg/trunk
