Clears all of the presentations that are queued for playback in the Media Session.
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| Return code | Description |
|---|---|
|
The method succeeded. |
|
The operation cannot be performed in the Media Session's current state. |
|
The Media Session has been shut down. |
This method is asynchronous. When the operation completes, the Media Session sends an MESessionTopologiesCleared event.
This method does not clear the current topology; it only removes topologies that are placed in the queue, waiting for playback. To remove the current topology, call IMFMediaSession::SetTopology with the MFSESSION_SETTOPOLOGY_CLEAR_CURRENT flag.
