I hacked the dfbvideosink to work with the (also hacked) geodefb to use 
the hardware video overlay. It is still a absolute (proof of concept) 
mess. I allocated a large videolayer 16*h X w, and use 
SetSourceRectangle() to switch the visible part of the large layer. The 
16 areas are then used as GstBuffers. That way i have hardware I420->RGB 
and hardware scaling on the Geode LX 800.
But the hack rather hardware specific.

So what hardware are you using, if it is slow (<800MHz) you will 
probably need a lot of hacking to get a normal running video.
