i do not doubt this; however it seems like i have some fundamental misunderstanding on the colorspace-definitions since i cannot get it right.

Perhaps, but I don't have enough info to help further.

Actually, the problem is that fromYUV420P() is defined to be an alias for fromYV12(), when it should have been fromYU12(), because YV12 is another way to say YVU420P... Y,V,U, in that order.
