AFAIK the PPE does have Altivec.
BTW what's the state of GCC for Cell? Can it schedule instructions for
the stripped-down Power-PC architecture of PPE? Power-PC G5 code will
not run optimally on a Cell. Did you try to tune GCC command-line
BTW what about the video output? You have to do use mplayer's software
scaler for full-screen video? How is that impacting performance?
...just wondering about the state of PS3 Linux. I'm somewhat
considering myself buying a PS3 as desktop computer replacement.
BTW how does ffmpeg's ffplay perform on theora playback? It uses its
own theora decoder that should be more efficient than libtheora (mplayer
couldn't use ffmpeg's theora-decoder for some time, maybe it can now?)
