@all
While the title says "AmigaOS 4.1," please note that any altivec optimizations will benefit everyone with mplayer/ffmpeg running on an altivec equipped PowerPC machine. That includes MorphOS users as well as the PowerPC ports of AROS & Linux.

AFAIK, core-codec is closed-source, which makes it irrelevant to us.

MorphOS MPlayer is AltiVec optimized

So is the AmigaOS mplayer. Both are based on the same code. However, the H.264 codec is partially altivec optimized. The equivalent X86 & ARM SIMD code is more developed. This is true regardless of which PowerPC OS you're talking about.

MorphOS users with altivec will benefit from any performance gains.

I know that. It can not be created commercial program for OS4?

For enough money, yes. However, don't think that they'll be happy with just a few thousand for such a port.
