GraphEdit Help

Control a Filter Graph

After you build or load a filter graph in GraphEdit, you can perform operations such as running, pausing, or stopping the graph. You can do this through the menu or the toolbar.

The following table lists the menu command, and equivalent Microsoft DirectShow method for each operation.

Command Menu DirectShow Method
Run On the Graph menu, click Play. IMediaControl::Run
Pause On the Graph menu, click Pause. IMediaControl::Pause
Stop On the Graph menu, click Stop. IMediaControl::Stop
Frame Step On the Graph menu, click Step. IVideoFrameStep::Step

If the graph is seekable, you can seek using the slider bar that appears below the toolbar.

Note   If the graph is seekable, the Stop command also seeks the graph back to the start of the stream.
