Well, I'm happy to see people using the v4l2 input format without
problems ;-)

I do not remember... Probably, I did not know the exact mapping, or I
found some contradictory documentation about this format, and I've not
been able to test it.

Anyway, if you have a v4l2 card supporting V4L2_PIX_FMT_{BGR,RGB}32,
you test the patch, and you confirm that it works, I'll commit it.
