Nah, I don't think so. DivX is too fast for that.
Talking about chroma speed:
I can use sad8 if chroma is not interpolated.
I can use sad8bi if chroma is interpolated in one-way (no rounding
control... not that it matters).
I have to interpolate to temporary memory if I need to compare
HV-interpolated chroma blocks - I bet it's slower.
Does anyone feel like writing a function which would interpolate both
ways AND do sad in the same loop? It will probably be needed for
block-based interpolation of luma components in qpel refinement, too. I
wouldn't mind if rounding control was there ;)
