Example

public bool _result = false;

      _renderedStreams = convertctrl.RenderedStreams;

      // set the result to what we expect (for the sample source video we should render all streams) 
      _result = (_renderedStreams == StreamFormatType.Video && _unrenderedStreams == StreamFormatType.None); 
   }
