How to use the MV I/O Output ActiveX Controls

The MV I/O Output Controls provide an easy way to display the results of filter graph configurations. All controls work in the same way.

Step 1: Use the MV I/O Renderer Filter to terminate an I/O Pin within your filter graph configuration.

Step 2: Add the MV I/O Control to your application form.

Step 3: Connect the MV I/O Control to the MV I/O Renderer filter. Call the Init() method of the control. The method has two parameters. The first is the label of the MV I/O Renderer filter within your filter graph configuration. In the sample above the label is "MV I/O Renderer". The second parameter is a reference to the MV Smart Control containing the filter graph configuration.

Sample Code (C++):

m_controlIODisplay.Init("MV I/O Renderer", m_controlVideo.GetControlUnknown());
