        progressPanel=new JPanel(); //实例化进度条容器  
        panel.add(progressPanel, BorderLayout.NORTH);  
  
        //添加进度条  
        progress=new JProgressBar();      
        progressPanel.add(progress);  
        //panel.add(progress,BorderLayout.NORTH);  
        progress.addMouseListener(new MouseAdapter() {  
            @Override  
            public void mouseClicked(MouseEvent e){     //点击进度条调整视屏播放进度  
                int x=e.getX();  
                PlayerMain.jumpTo((float)x/progress.getWidth());  
            }  
        });  
        progress.setStringPainted(true);  
          
          
        controlPanel=new JPanel();      //实例化控制按钮容器  
        panel.add(controlPanel,BorderLayout.SOUTH);  
          
        //添加停止按钮  
        btnStop=new JButton("停止");  
        btnStop.addMouseListener(new MouseAdapter() {  
            @Override  
            public void mouseClicked(MouseEvent e) {  
                // TODO Auto-generated method stub  
                PlayerMain.stop();  
            }

        //添加播放按钮

        btnPlay.addMouseListener(new MouseAdapter() {  
            @Override  
            public void mouseClicked(MouseEvent e) {  
                // TODO Auto-generated method stub  
                PlayerMain.play();  
            }  
        });  
        controlPanel.add(btnPlay);  
          
        //添加暂停按钮  
        btnPause=new JButton("暂停");  
        btnPause.addMouseListener(new MouseAdapter() {  
            @Override  
            public void mouseClicked(MouseEvent e) {  
                // TODO Auto-generated method stub
                //PlayerMain.dispose();
                PlayerMain.pause();  
            }  
        });  
        controlPanel.add(btnPause);  
          
        //添加声音控制块  
        slider=new JSlider();  
        slider.setValue(80);  
        slider.setMaximum(100);  
        slider.addChangeListener(new ChangeListener() {  
              
            @Override  
            public void stateChanged(ChangeEvent e) {  
                // TODO Auto-generated method stub  
                PlayerMain.setVol(slider.getValue());  
            }  
        });  
        controlPanel.add(slider);  
    }  
      
    //获取播放媒体实例（某个视频）  
    public EmbeddedMediaPlayer getMediaPlayer() {  
        return playerComponent.getMediaPlayer();  
    }  
      
    //获取进度条实例  
    public JProgressBar getProgressBar() {  
        return progress;  
    }  
      
}  

效果如下：

（6）在视频播放面板上操作视频接口方法：

playerComponent = new EmbeddedMediaPlayerComponent();
        panel.add(playerComponent);
        //视频表面的鼠标事件
        playerComponent.getVideoSurface().addMouseListener(new MouseListener() {
            
            @Override
            public void mouseReleased(MouseEvent e) {
                // TODO Auto-generated method stub
                
            }
            
            @Override
            public void mousePressed(MouseEvent e) {
                // TODO Auto-generated method stub
                
            }
            
            @Override
            public void mouseExited(MouseEvent e) {
                // TODO Auto-generated method stub
                
            }
            
            @Override
            public void mouseEntered(MouseEvent e) {
                // TODO Auto-generated method stub
                
            }
            
            @Override
            public void mouseClicked(MouseEvent e) {
                // TODO Auto-generated method stub
                System.out.println("**************");
            }
        });

（7）项目总结：应用了开源vlc，运用了jna技术，实现了多媒体视频播放。
