title: how to get duration length of the Video using xuggler
body: <p>this code reads the time duration in long, but when it converts into the date with time format 'hh:mm:ss' it gives different value and the video length is 
  00:08:07. what is wrong in this code</p>
  
  <pre><code>String filename = "C:\\Documents\\Airtel Youthstar-Tutorial.mp4";   
      IContainer container = IContainer.make();  
      int result = container.open(filename, IContainer.Type.READ, null);  
      long duration = container.getDuration();  
      System.out.println("Duration (ms): " + duration);
