CaptureConnection class

A connection between a specific pair of capture input and capture output objects in a capture session.

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

You can add an CaptureConnection instance to a session using the CaptureSession.addConnection method only if the CaptureSession.canAddConnections includes the connection. When using the CaptureSession.addInput or CaptureSession.addOutput method, the session forms connections 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.
