I really need some kind of video output. v4l2grab is not useful
there. v4l2gl might be, but I don't think I have enough dependencies.

Umm, and it looks like libv4l can not automatically convert from
GRBG10.. and if it could, going through RGB24 would probably be too
slow on this device :-(.

Is there an example using autogain/autowhitebalance from
libv4lconvert?
