Re: Mplayer Altivec test version for G4 and PA6T-1682M

And mplayer writen in that good way with separated parts, and when build for altivec, some objects builds as for altivec, some are not. Probably liveforit just build all objects for altivec.

But that anyway make no big differences to run altivec based bins on non altivec machines of course.

Yes, compiling all objects with altivec enabled does make a difference for non-altivec machines. When you enable altivec, you're giving the compiler permission to use altivec instructions whenever it feels that it's the optimal choice. You don't even have to enable autovectorization for that to happen.
