OK - I spend a few hours converting (and debugging) milan's YV12 optimized version of
WarpSharp. It's quite fast aleady. I made a few adjustments to it, but nothing major.
Be very careful - you cannot use it after a crop, since ffdshow assumes that input pitch = output pitch! This will give the wellknown distorted pictures! I hope someone else has the time to take up the challenge?
I also have a ColorYUV lying at home, so people shouldn't bother converting it - it's already done!
Edit: It's on the alpha page - forgot to tell ya
