Example

using Leadtools; 
using Leadtools.MediaFoundation; 
using LeadtoolsMediaFoundationExamples.Fixtures; 
 
 
public bool _result = false; 
public PlayCtrlForm _form = new PlayCtrlForm(); 
double _duration = 0.0; 
double _currentPos = -1; 
 
public void PlayExample() 
{ 
   // reference the play control 
   PlayCtrl playctrl = _form.PlayCtrl; 
 
   // input file 
   string inFile = Path.Combine(LEAD_VARS.MediaDir, "PlayCtrl_Source.avi"); 
 
   try 
   { 
      // set autostart to false 
      playctrl.AutoStart = false; 
 
      // set the play count to 2 
      playctrl.PlayCount = 2; 
 
      // set our source media file 
      playctrl.SourceFile = inFile; 
 
      // get the reported duration 
      _duration = playctrl.Duration; 
 
      // set the playback rate to 2x 
      if (playctrl.IsRateSupported(2.0)) 
         playctrl.Rate = 2.0; 
 
      // set event handler to get tracking position changes 
      playctrl.TrackingPositionChanged += new TrackingPositionChangedEventHandler(PlayCtrl_TrackingPositionChanged); 
 
      // run it! 
      playctrl.Run(); 
   } 
   catch (Exception) 
   { 
      _result = false; 
   } 
 
   // we'll loop on the state and pump messages for this example. 
   // but you should not need to if running from a Windows Forms application. 
   while (playctrl.State == PlayState.Running) 
      Application.DoEvents(); 
 
   // set the result to determine if the reported duration 
   // is the same as the final position from tracking 
   _result = (_duration == _currentPos && _duration > 0.0); 
} 
 
void PlayCtrl_TrackingPositionChanged(object sender, TrackingPositionChangedEventArgs e) 
{ 
   // get the frame and tracking positions for demonstration only 
   int frame = _form.PlayCtrl.CurrentFramePosition; 
   int tracking = _form.PlayCtrl.CurrentTrackingPosition; 
 
   // get the current position 
   _currentPos = Math.Max(_currentPos, _form.PlayCtrl.CurrentPosition); 
}
