the win32 dlls don't support yv12, or the yv12 support is very
buggy/unstable. the main problem is that yv12 is planar, but the win32
codec interface was designed for single plane video frames.
(no way to specify 2nd and 3rd plane pointers)

the only working yv12 win32 codec is indeo5ds.

afaik transcode _converts_ every yuv formats to yv12.
