IMediaControl::StopWhenReady (Windows Embedded CE 6.0)
1/6/2010
This method waits for an operation such as Pause to complete, allowing filters to queue up data, then stops the filter graph.
Syntax
HRESULT StopWhenReady( );
Parameters
None.
Return Value
Returns an HRESULT value.
Remarks
Changing the current position when stopped will not normally repaint the video window with the new position. Applications will need to enter Pause mode to do this. Calling StopWhenReady instead of simply calling Stop after this pause ensures that the graph is fully paused, and that data has arrived at the video renderer and has been displayed before the graph is stopped.
This method is run asynchronously so that the application regains control immediately and can respond to user input. Use this method rather than calling IMediaControl::GetState with an INFINITE time-out, followed by IMediaControl::Stop.
