So anybody get calling createSnapshotWithRect on the CameraView class to work?
I've tried called it against the CameraView and the previewView of the CameraView, and neither works. (drawing it to a imageview results in a black area)

I'm trying to find a way to get the picture currently on the CameraView during live preview since it'd be so much faster than calling takePicture over and over again.

Or... does anybody know of a way to use LKLayer or CGContexts to retrieve the bitmap data from a view or layer?
