[Ffmpeg-devel] [REQUEST] MMX/MMX2 and SSE optimizations for H.264 decoding

[Gamester17]

Yes there already are some MMX integer optimization for H264 but what about 
SSE (Streaming SIMD Extensions) optimizations?, isn't SSE suppose to be much 
more powerfull than MMX (and in fact be the thing that replaces MMX)? 

To me (as a none-programmer)it looks like the only video codec in FFmpeg 
that have any SSE optimization is the VP3 decoder (and those are in the 
newer SSE2 format so can't be used by 'older' processors as I believe that 
Intel Pentium 4 is the first processor which supports SSE2?)?
