Source
Indicate video source objects associated with video input object
Description
The Source property is a vector of video source objects that represent the physical data
sources connected to a device. When a video input object is created, the toolbox creates a
vector of video source objects associated with the video input object.
Each video source object created is provided a unique source name. You can
use the source name to select the desired acquisition source by configuring the
SelectedSourceName property of the video input object.
A video source object's name is stored in its SourceName property. If a video source
object's SourceName is equivalent to the video input object's SelectedSourceName, the
video source object's Selected property has a value of 'on'.
The video source object supports a set of common properties, such as SourceName.
Each video source object can also support device-specific properties that control
characteristics of the physical device such as brightness, hue, and saturation. Different
image acquisition devices expose different sets of properties.
A video source is defined to be a collection of one or more physical data sources 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.
The Source property encapsulates one or more video sources. To reference a video
source, you use a numerical integer to index into the vector of video source objects.
