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
Loren Merritt	20d565be6d	put loop counter in a register if possible. makes some of the qpel functions 3% faster. Originally committed as revision 11876 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
