Comment (by Balling):

 > really strange, may be YUView actually at fault here :/ I added third
 (intermediate) bmp to it and by moving all 3 files in and out Difference
 sequence item I got match :/


 You should not use BMP, BMP uses bgr, not rgb, there are bugs with
 handling bgr to yuv420p and from yuv420p to bgr. No, YUView is accurate.
