The MediaStreamSourceSwitchStreamsRequest class has these types of members:
The MediaStreamSourceSwitchStreamsRequest class has these methods. With C#, Visual Basic, and C++, it also inherits methods from the Object class.
|GetDeferral||Defers completing the MediaStreamSource.SwitchStreamsRequested event.|
The MediaStreamSourceSwitchStreamsRequest class has these properties.
|Read-only||Gets the stream descriptor for the stream that is now selected by the MediaStreamSource.|
|Read-only||Gets the stream descriptor for the stream which is no longer selected by the MediaStreamSource.|
You can use a deferral when you want to make an asynchronous call in response to the MediaStreamSource.SwitchStreamsRequested event. For example, if you need to establish a HTTP connection or open a file for reading. The MediaStreamSource will then wait for you to mark the deferral as complete before it begins raising the SampleRequested event.
To create a deferral, call the GetDeferral method to instruct the MediaStreamSource to wait for your asynchronous call to complete. When you are ready to start receiving SampleRequested events, call the Complete method to end the deferral.
See the MediaStreamSource Sample for an example of using Media Stream Source in a Windows Store app.
