When a camera, that was working fine, for some reason goes off the air, the preview window says 'no device selected'.
I have always been able to restart the camera by choosing 'detect webcam' and choosing the camera again.
I am trying to write an Autoit script that can sense when the camera drops off but I can't find any setting or window that I can interrogate to find out the screen says 'no device selected'.
Is there a setting somewhere that I could check?
