I wanted to see how fast things would be when the yuv->rgb transformation
was skipped. As far as I understand yuv, the Y-part is the luminace of the
pixel, and I should therefore get a b&w-picture if I just set the r, g and b
values of a pixel to the Y-value.

I wrote a short function doing that, and set v_out->b_need_renderer to "0".
But vlc still writes "locking module yuv" - do I have to do anything else to
disable software yub->rgb transformation?
