IMediaControl Interface

The IMediaControl interface provides methods for controlling the flow of data through the filter graph. It includes methods for running, pausing, and stopping the graph. The Filter Graph Manager implements this interface. For more information on filter graph states, see Data Flow in the Filter Graph.

In addition to the methods inherited from IDispatch, the IMediaControl interface exposes the following methods.

Method Description
Run Runs all the filters in the filter graph.
Pause Pauses all filters in the filter graph.
Stop Stops all the filters in the filter graph.
StopWhenReady Pauses the filter graph, allowing filters to queue data, and then stops the filter graph.
