[OpenDivX] Optimization questions

[Mattias Blomqvist <Mattias.Blomqvist@home.se>]

Hello

I'm thinking of doing some work optimizing the decore. Foremost in intel
(mmx-)assembler.
What I've seen so far that can be quite easily optimised is the routines
in yuv2rgb_mmx.c and basic_prediction_mmx.c. My questions are:
Is any of the routines in basic_prediction used alot so there is any use
in optimizing them?
Is the yuv2rgb routines used at all? Considering allmost all relatively
modern graphic cards have that feature in hardware and it is available
atleast under Windows and Linux (dont know about the others).

BR,
Mattias Blomqvist
