GraphEdit Help |
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.
