See Also: AVCaptureConnection Members
A AVFoundation.AVCaptureConnection encapsulates the link between an AVFoundation.AVCaptureInput (more specifically, between an individual AVFoundation.AVCaptureInputPort in the AVCaptureInput.Ports property of the AVFoundation.AVCaptureInput and the AVFoundation.AVCaptureOutput).
AVFoundation.AVCaptureConnections are formed automatically when inputs and outputs are added via AVCaptureSession.AddInput and AVCaptureSession.AddOutput.
