|IWMInputMediaProps||Retrieves the properties of an input stream.|
|IWMMediaProps||Used as the base interface for the other media-property interfaces (input, output, and video).|
|IWMVideoMediaProps||Manages the properties of a video stream. This is an optional interface, available only for video streams.|
