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 :-(. > IMO, the above belongs to a separate processing module under > lib/libv4lconvert/processing/ Is there an example using autogain/autowhitebalance from libv4lconvert?
