Please do double check. I'm not 100% sure, but last time I checked the
changelog showed that he had re-written some calls to IPP with
hand-written asm routines.
I have send a patch some time ago which contained the differences
between current code in FFmpeg and the one in mplayer-w100 and AFAIR,
there were some unmerged code.
With DADVSI (http://en.wikipedia.org/wiki/DADVSI), France finally has
a lead on USA on selling out individuals right to corporations!
Vive la France!
