using Leadtools; 
using Leadtools.MediaFoundation; 
using LeadtoolsMediaFoundationExamples.Fixtures; 
 
 
public bool _result = false; 
public StreamFormatType _renderedStreams = StreamFormatType.None; 
public StreamFormatType _unrenderedStreams = StreamFormatType.None; 
public PlayCtrlForm _form = new PlayCtrlForm(); 
 
public void RenderedStreamsExample() 
{ 
   // reference the play control 
   PlayCtrl playctrl = _form.PlayCtrl; 
 
   string inFile = Path.Combine(LEAD_VARS.MediaDir, "PlayCtrl_SourceVideoOnly.avi"); 
 
   try 
   { 
      // set autostart to false 
      playctrl.AutoStart = false; 
 
      // set our source media file 
      playctrl.SourceFile = inFile; 
 
      // run it! 
      playctrl.Run(); 
 
      // get the reported duration 
      _renderedStreams = playctrl.RenderedStreams; 
      _unrenderedStreams = playctrl.UnrenderedStreams; 
 
      // set the result to what we expect (for the sample source video we should render all streams) 
      _result = (_renderedStreams == StreamFormatType.Video && _unrenderedStreams == StreamFormatType.None); 
   } 
   catch (Exception) 
   { 
      _result = false; 
   } 
}
