 The two conversions should be identical, right?  Since rgb24<->bgr24 is
 lossless, bgr->rgb->yuv should produce the same output as bgr->yuv.  If it
 doesn't, it's not working right.

 ffmpeg -f rawvideo -video_size 256x256 -pix_fmt bgr24 -i testin.raw
 -sws_flags lanczos -f rawvideo -pix_fmt yuv420p md5:
