When the capture source is started, it fills with data from the relevant capture device. For video, this data can now be displayed in any associated VideoBrush. You can also grab video frames by calling CaptureImageAsync, and handling CaptureImageCompleted to obtain the result.

To get raw data for either video or audio, you must use the associated sink (AudioSink or VideoSink).
