Just before i start decrypting your assembly, to map the
function names to more explicit meaning, and then starting
hacking bf interpolate to use them, and of course implementing
a C backend set of functions... (i'll do tomorrow, cause i'm
pretty tired today, too much J2EE coding kills my coding
energy)
How much speedup can i expect doing this change ? Is it only a
few % or the several % i'm looking for to catch up with ffmpeg?
Btw, if this proves to be really helpful, i guess using such a
trick for qpel will be much harder to implement, won't it ?
