MediaStreamSource.OpenMediaAsync Method
Silverlight
The MediaElement calls this method to ask the MediaStreamSource to open the media.
Namespace: System.Windows.Media
Assembly: System.Windows (in System.Windows.dll)
After the collection of MediaStreamDescription objects is instantiated, a developer should call ReportMediaCompleted with the collection of MediaStreamDescription objects. If the media cannot be opened, the ErrorOccurred method should be called instead.
