Properties

The MediaStreamSourceSampleRequest class has these properties.

PropertyAccess typeDescription

Sample

Read/writeSets the MediaStreamSample requested by the MediaStreamSource. Applications deliver a MediaStreamSample to the MediaStreamSource by assigning a value to this property.

StreamDescriptor

Read-onlyGets the IMediaStreamDescriptor interface of the stream for which a MediaStreamSample is being requested.

 

Remarks

You can use a deferral when you want to make an asynchronous call to retrieve the MediaStreamSample. The MediaStreamSource will then wait for you to supply the MediaStreamSample until you mark the deferral as complete.

To create a deferral, call the GetDeferral method to instruct the MediaStreamSource to wait for the MediaStreamSample. After you have assigned the MediaStreamSample to the Sample property of the MediaStreamSourceSampleRequest object, call the MediaStreamSourceSampleRequestDeferral.Complete method to end the deferral.

See the MediaStreamSource Sample for an example of using Media Stream Source in a Windows Store app.
