does that work on a wider range of videos and CPUs ?
from what i remember really long ago, that codecs which change the QP
alot between MBs might need too much data cache on some CPUs for this
to be faster.
But time has passed and the environment changed so maybe this is better
now.

But either way, great work!
please submit a patch for this if it is consistently better or equal

Thanks
