MENewPresentation event
Raised by a media source that provides topologies through the IMFMediaSourceTopologyProvider interface, such as the sequencer source. The source raises the event when it has a new presentation. The Media Session forwards this event to the application.
Event values
Possible values retrieved from IMFMediaEvent::GetValue include the following.
| VARTYPE | Description |
|---|---|
| VT_UNKNOWN |
Pointer to the IMFPresentationDescriptor interface of the presentation descriptor for the new presentation. |
Remarks
The application can get the topology that corresponds to the presentation descriptor by calling IMFMediaSourceTopologyProvider::GetMediaSourceTopology on the media source. The application can then queue the new topology on the Media Session by calling IMFMediaSession::SetTopology.
