So you get wrong colors when YV12 is selected.
Do you get wrong colors too when I420 is selected ?
In DirectFB is I420 vs YV12 is swapped. I know that video is YV12. But
we have to specify I420 in DirectFB. With X11 it is YV12 :-).
Look at the code of gfxdriver/radeon/radeon_overlay.c, (line 661):
661 if (surface->format == DSPF_YV12) {
662 __u32 tmp = offsets[1];
663 offsets[1] = offsets[2];
664 offsets[2] = tmp;
665 }
They swap U/V in case of YV12 :-( .
There is to my optinion no need to swap again.
