 public static void main(String[] args) {
        // TODO code application logic here
        Player player = null;
 
 
 
        String mediaFile ="rtsp://[]:554/live.sdp";
        try {
 
        MediaLocator mrl = new MediaLocator(mediaFile);
        //URL url = new URL(mediaFile);
        // DataSource ds = Manager.createDataSource(mrl);
        player = Manager.createPlayer(mrl);
 
 
        //player = Manager.createPlayer(mrl);
       // player.realize();
       // player.prefetch();
       JFrame jf = new JFrame();
       jf.add(player.getControlPanelComponent());
       jf.add(player.getVisualComponent());
       jf.setVisible(true);
       jf.pack();
        //player.start();
 
        }
        catch (Exception e) {
        System.err.println("Got exception "+e.getMessage());
        }
    }

voici les erreurs
