An example on using AVFoundation and AVCaptureSession to display a real-time capture from a raw stream using a video camera.
Based on Apple's Technical Q&A QA1702: How to capture video frames from the camera as images using AV Foundation http://developer.apple.com/library/ios/#qa/qa1702/_index.html
iOS 4.0 and up.
This example will only run correctly on a iOS device, this requires a purchased version of MonoTouch.
