Thanks. Yes, it is obviously wrong, as there was another 
V4L2_PIX_FMT_RGBX32 in the file already. I thought I checked that, but 
apparently not...

I have to say I don't get the V4L2 formats. Why is

V4L2_PIX_FMT_XBGR32  BGRX-8-8-8-8

so the X is not beside the R in the define. But

V4L2_PIX_FMT_XRGB32  XRGB-8-8-8-8

X is beside the R. Well, doesn't matter.
