Don't see any advantage in doing this apart from "attracting user-space 
developers to develop for v4l2 output interface," which doesn't seem like 
a worthy goal in itself. Whereas with my translation you get access to 
existing user-space applications and to a powerful in-kernel API, and 
achieve a better interoperability with video-input streams.

Thanks
