Java Media API

• Java Advanced Imaging(JAI)
• Java 3D
• Java Media Framework(JMF)

使用JMF

• 示例
• 重点：

  URL url = file.toURI().toURL();
  player = Manager.createRealizedPlayer(playFile.toURI().toURL());
  player.addControllerListener(this);//添加监听
  player.prefetch();//预取
  

  监听器函数(ControllerListener里的具体函数)：

  public void controllerUpdate(ControllerEvent e){
  if(e instanceof EndOfMediaEvent){
    idx++;
    if(idx < this.mp3List.size()){
      this.start();
    }
    return;
  }
  if(e instanceof PrefetchCompleteEvent){
    player.start();
    return;
  }
  }
  

使用第三方库

• 如javalayer的mp3播放库

  import javazoom.jl.player.Player;
  BufferedInputStream buffer = new BufferedInputStream(new FileInputStream(filename))
  player = new Player(buffer);
  player.play();
