Yes I know according to v4l2 the auto exposure control takes 4 different values, with 0 being auto and 1 being manual however, since I've changed the type to a simple boolean value 1 is on and 0 is off. Any program that lets you modify the controls should be using the query control ioctl which should tell it to use a boolean value so ti ought to be ok. The only other i an see as i said would be to define our own custom control.
