SelectedSourceName
Specify name of currently selected video source
Description
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 string. 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.

Data type String
Values The video input object assigns a name to each video source object it
creates. Names are defined at object creation time and are vendor
specific.
By default, the toolbox uses the first available source name.
