v4l is dealing with for video-input like tv-card, webcams and so on.
colorspace conversion is no subject of v4l.
anyway. i had the same idea some weeks ago. i need it for ggitv, a
tv-application.
as far as i know we need:
1. a YUYV-visual
2. crossblit-function between RGB-YUYV
the crossblit can be accelerate by the gfx-card under kgi(con).
