Player exception..

Question

Hello everey body..
I have aproblem with recording files..
I make aprogram do the following:
1) browse and an audio file.
2) Then browse again and select a video file.
3) Merge the 2-files to one file.
4) play the merged file at player..
The code for merging is as follows..
private void MergeActionPerformed(java.awt.event.ActionEvent evt) {//GEN-FIRST:event_MergeActionPerformed
        // TODO add your handling code here:
        MediaLocator mlv = new MediaLocator(VideoFile);
         MediaLocator mla = new MediaLocator(AudioFile);
        try{
        video=Manager.createDataSource(mlv);
        audio=Manager.createDataSource(mla);
         DataSource array[] = {video,audio };
        d =Manager.createMergingDataSource(array);
        catch(Exception e){
            e.printStackTrace();
      OnDemandMPlayerodmp = new OnDemandMPlayer(d);
         PlayerP.add(odmp);
    }//GEN-LAST:event_MergeActionPerformedRemark:
1) OnDemandMPlayer is the class resbonsible for playing the merge file
2) PlayerP is the panel that hold the MPlayer to view the played file on the screen.
The code for the MPlayer class:
import java.awt.BorderLayout;
import javax.media.*;
import javax.media.protocol.DataSource;
import javax.swing.*;
public class OnDemandMPlayer extends JPanel{
    Player player = null ;
    /** Creates a new instance of OnDemandMPlayer */
    public OnDemandMPlayer(DataSource ds) {
        try{
            player = Manager.createPlayer(ds);
            player.addControllerListener(
                    new ControllerListener() {
                public void controllerUpdate(ControllerEvent e) {
                    if ( e instanceof RealizeCompleteEvent)
                        player.prefetch();
                    if ( e instanceof PrefetchCompleteEvent) {
                        add(player.getVisualComponent(),BorderLayout.CENTER);
                        add(player.getControlPanelComponent(),BorderLayout.SOUTH);
                        validate();
                        player.start();
                    if ( e instanceof EndOfMediaEvent) {
                        player.setMediaTime(new Time(0));
                        player.start();
            player.realize();
        } catch(Exception exe){
            System.out.println(exe);
}So when i run the action of the MergeAction after selecting the file i have the exception as follows:
javax.media.NoPlayerException: Cannot find a Player for: com.ibm.media.protocol.MergingPullDataSource@e102dc
So, What is the problem and how can i ensure that the files are merged correctly.. since there is no preview are available at the ondemendplayer window..

Sorry for one mistake in my description. Instead of getDataSource() it is going to be getDataOutput(). So,
1. Get Audio+Video capture devices
2. Get their media locators
3. From these media locators create audio and video data sources
4. From those 2 data sources create 1 merged data source
5. From that merged data source create processor
6. Realize and start this processor
7. From realized processor get its data source (i.e. getDataOutput())
8. Finally, from that data source you can try to get your player.
