Windowed mode is better performance-wise.

Our yuv converter has a ss2 optimized code path, so I find it strange that it ends up at the top (decoding the video generally requires more cpu than the yuv conversion, though this might depend on the codec used)

This would be the top level method for video decoding, so this makes sense.

Though this makes no sense, this is just a getter method.

Do you have percentages/numbers for these methods?
