Question

public void mediaPlayer(final String path, final JPanel panel) {
    new Thread() {
        public void run() {
            try {
                Player p = Manager.createRealizedPlayer(new  File(path).toURL());
                Component ctrlpanel = p.getControlPanelComponent();
                Component player = p.getVisualComponent();
                player.setBounds(10, 20, 300, 170);
                ctrlpanel.setBounds(10, 191, 300, 20);
                panel.add(player);

                panel.add(ctrlpanel);
                panel.repaint();
                p.start();
                System.out.println(" Player Started");
            } catch (NoPlayerException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (CannotRealizeException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (MalformedURLException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }.start();

我尝试代码播放视频文件，但出现了一些错误。
