Specify name of currently selected video source
The SelectedSourceName property specifies
the name of the video source object from which the video input object
acquires data. The name is specified as a character vector. By default,
the video input object selects the first available video source object
stored in the Source property.
The toolbox defines a video source as one or more hardware inputs that are treated as a single entity. For example, hardware supporting multiple RGB sources, each of which is made up of three physical connections (red-green-blue), is treated as a single video source object.
