I don't know - Gerard did not accepted my code which allowed function
inlining and have replaced it with double function's pointer. Instead he
have performed some C-level optimization. He wants to run 386 optimized
ffmpeg on non-MMX (and non-FPU) Intel cpus.

I'm not sure that this code will live longer a several hours in ffmpeg-CVS :(

After purchasing a new video hardware - I forgot, what is
non real-time playback. Thus codec's speed is interested for me only
from theoretical point now.

AFAIK divx32c has enough aggressive MMX(1,2) optimized code
so it's a little strange for me - maybe you should test a several
movies?

Undoubtedly - mplayer must have ffmpeg stuff in any form since it's only
solution for non Intel machines.
