Cloning through jmf( video problem)

Question

Hello friends, I am trying to clone the captured video and run it at the same time.
here is the code
import java.awt.*;
import java.net.*;
import javax.media.*;
import java.awt.event.*;
import javax.swing.*;
import javax.media.format.*;
import javax.media.protocol.*;
import javax.media.control.*;
import java.util.*;
/* This program is to capture from a webcam and save it in disk */
public class run extends JFrame implements ControllerListener,ActionListener
     Processor p=null;
     DataSink sink;
     MenuBar mb;
     MenuItem start,stop;
     Menu file;
     Vector dl;
     MediaLocator ml;
     DataSource ds;
     run()
          setVisible(true);
          setSize(800,600);
          setLayout(new BorderLayout());
          mb=new MenuBar();
          file=new Menu("File");
          start=new MenuItem("Start");
          // start button gets enabled only after the processor is realized
          // I start the processor and sink after clicking the start button
          // I start the processor and sink after clicking the start button
          start.setEnabled(false);
          stop=new MenuItem("Stop");
          // I use stop button to stop the processor and the sink
          file.add(start);
          file.add(stop);
          mb.add(file);
          setMenuBar(mb);
          start.addActionListener(this);
          stop.addActionListener(this);
          addWindowListener
          (new WindowAdapter()
                    public void windowClosing(WindowEvent we)
                         System.exit(0);
          try
               dl=CaptureDeviceManager.getDeviceList(new VideoFormat(VideoFormat.YUV));
               ml=((CaptureDeviceInfo)dl.firstElement()).getLocator();
               p=Manager.createProcessor(ml);
               p.addControllerListener(this);
               p.configure();
               Thread.sleep(3000);
               p.setContentDescriptor(new FileTypeDescriptor(FileTypeDescriptor.MSVIDEO));
               /* When I use {color:#ff6600}Quicktime the File is created with zero size always*/
               /* So I used MSVideo and saved the file as .avi*/
               /* Now the file is created with some size but I am not able to play it with every player*/
               /* Note : I ran the Video capture program successfully which means the capturing is done without any problem*/
               /* So the problem is with saving it in disk*/
               /* When I open it in JMStudio it says Cannot Realize: Cannot parse the input media */
               p.realize();               
               Thread.sleep(3000);
          catch (Exception e)
               System.err.println("Got exception "+e);
     public void actionPerformed(ActionEvent ae)
          try
               if(ae.getActionCommand().equals("Start"))
                    sink.open();
                    sink.start();
                    p.start();
                    System.out.println("start"+p);          
               else
                    p.stop();
                    p.close();
                    //Thread.sleep(1000);
                    sink.stop();
                    sink.close();
                    System.out.println("stop");
          catch(Exception e)
               System.out.println("Some problem "+e);
     public synchronized void controllerUpdate(ControllerEvent ce)
          try
               if (ce instanceof RealizeCompleteEvent)
                    Component comp;
                    System.out.println("Realized");
                    sink = Manager.createDataSink(p.getDataOutput(), new MediaLocator("file:/e:/J-Solve1.avi"));
                    start.setEnabled(true);
                    if ((comp = p.getVisualComponent()) != null)
                         add (BorderLayout.CENTER, comp);
                    else
                         System.out.println("No visual component");
                    if ((comp = p.getControlPanelComponent()) != null)
                         add (BorderLayout.SOUTH, comp);
                    validate();
                    System.out.println("Updated");
          catch(Exception e)
               System.out.println("Exception rasied "+e);
     public static void main(String s[])
          new run();
          MediaLocator ml;
          DataSource ds = null;
          Clone clone = new Clone();
          ml = new MediaLocator("file:/e:/J-Solve1.avi");
          ds = Manager.createDataSource(ml);
          ds = Manager.createCloneableDataSource(ds);
          clone.open(ds);
          clone.open(((SourceCloneable)ds).createClone());
}But it gives error.
though if you remove below given part from "main" then it will capture.
MediaLocator ml;
          DataSource ds = null;
          Clone clone = new Clone();
          ml = new MediaLocator("file:/e:/J-Solve1.avi");
          ds = Manager.createDataSource(ml);
          ds = Manager.createCloneableDataSource(ds);
          clone.open(ds);
          clone.open(((SourceCloneable)ds).createClone());but I want to capture as well as play at the same time. What to do. Please tell me???
Thanks in advance......
