[mpeg2-dev] [PATCH] SSE2 idct optimizations

2008-02-24 Thread Diego Biurrun
This patch supercedes previous incarnations sent in by Petri and Lionel. It takes the idct part from their patches along with minor cleanups and should be easier to review/verify. The motion compensation part contained in Petri's/Lionel's patch is not yet proven to give any sort of improvement, be
