Detailed Description
Media data from a soundcard, soundserver, camera or any other hardware device supported by the backend.
This class gives you access to the capture capabilities of the backend. There might be more than only one possible capture source, for audio, as well as for video. A preferable device may easily be obtained by providing a capture category.
