I was referring to "Freeze" thread.

IIRC, you can expect AVR32-specific stuff related to yuv2rgb from Mans too.

Since regressions are passed now (with a patch, of course) I can apply it.
Additional patch is required to drop --enable-swscale, GPL check for it and
dropping imgconvert - someone have to write it though.
