supported Input formats: YV12, I420, IYUV, YUY2, BGR32, BGR24, Y8, Y800
supported Input formats: YV12, I420, IYUV, YUY2, BGR32, BGR24, RGB32, RGB24, Y8, Y800
supported output formats: YV12, I420, IYUV, BGR15, BGR16, BGR24, BGR32 (grayscale soon too)
BGR15/16 support dithering
unscaled special converters
YV12/I420/IYUV -> BGR15/BGR16/BGR24/BGR32
YV12/I420/IYUV -> YV12/I420/IYUV
YUY2/BGR15/BGR16/BGR24/BGR32/RGB24/RGB32 -> same format
