Remarks

You can use a deferral when you want to make an asynchronous call in response to the MediaStreamSource.Starting 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 on the MediaStreamSourceStartingRequest object 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 UWP app.
