Hi Marcus,

can you please explain a little more what you did exactly with this 
pipeline?

Xv out is working fine on my board, it just doesn't work with gstreamer 
applications like cheese (http://www.gnome.org/projects/cheese).

It should work out of the box without hacking like it does with intel 
graphics.
