An AVCaptureConnection object represents a connection between capture input and capture output objects associated with a capture session.

Capture inputs (instances of AVCaptureInput) have one or more input ports (instances of AVCaptureInputPort). Capture outputs (instances of AVCaptureOutput) can accept data from one or more sources (for example, an AVCaptureMovieFileOutput object accepts both video and audio data).

You can only add an AVCaptureConnection instance to a session using addConnection: if canAddConnection: returns true. When using addInput or addOutput, connections are formed automatically between all compatible inputs and outputs. You only need to add connections manually when adding an input or output with no connections. You can also use connections to enable or disable the flow of data from a given input or to a given output.
