Thanks! Unfortunately the linear blend deinterlacer does more damage
to luma than I expected, so I think I'll have to stick with using the
swscaler's gaussian blur for now, or else wait for chroma-only
deinterlacer. I think the scaler will turn out ok tho -- I decided not
to scale to fix the aspect, but instead store aspect in the mpeg4
headers.
