我使用 javax.media.Player 在 java Swing 中播放视频,它工作得恰到好处。但是当我需要删除刚刚播放的视频时,它会提示该视频被某些程序占用,肯定是MediaPlayer。谁能教我如何在视频播放结束时释放资源?
代码如下:
public class VideoPlayerPanel extends javax.swing.JPanel {
private Player mediaPlayer;
private Component video = null;
private Component controls = null;
/**
* Creates new form VideoPlayerPanel
*/
public VideoPlayerPanel() {
initComponents();
}
public void play(URL url) {
if (video != null) {
remove(video);
}
if (controls != null) {
remove(controls);
}
try {
mediaPlayer = Manager.createRealizedPlayer(url);
video = mediaPlayer.getVisualComponent();
controls = mediaPlayer.getControlPanelComponent();
this.add(video, BorderLayout.CENTER);
this.add(controls, BorderLayout.SOUTH);
validate();
revalidate();
} catch (IOException ex) {
Logger.getLogger(VideoPlayerPanel.class.getName()).log(Level.SEVERE, null, ex);
} catch (NoPlayerException ex) {
Logger.getLogger(VideoPlayerPanel.class.getName()).log(Level.SEVERE, null, ex);
} catch (CannotRealizeException ex) {
Logger.getLogger(VideoPlayerPanel.class.getName()).log(Level.SEVERE, null, ex);
}
}
......
}`
