It works nicely with UVC drivers. The problem is that libv4l2 isn't aware of it, and endup taking terribly decision the least quickly lead to crash. I'm not sure what that right approach. It seems non-trivial to support it, at least it would require a bit more knowledge of the converter code and memory model. Maybe we should at least make sure that CREATE_BUF fails if we are doing conversion ? Some input on that would be appreciated. cheers, Nicolas
