Detailed Description

This class is the interface to query and select the available video/audio inputs/outputs.

This class manages STL-lists of objects of class Connector which describe an input or output of a capture device. Applications can get these lists and get/set the currently used connector of a special type. The methods to deal with outputs are only of partial interest for capturing but have been added for completeness. Application must use the API-dependent CaptureDevice-object to get an ConnectorManager. The default implementations of the mehtods in this class are a noop.
