播放媒体文件流，真机测试发生异常的代码

    Player p = Manager.createPlayer(m_isInputImage,"audio/amr");

    p.realize();

   // Set a listener.

   p.addPlayerListener(new Listener());

   // Grab volume control for the player.

   // Set Volume to max.

   vc = (VolumeControl)p.getControl("VolumeControl");

   if (vc != null)

      vc.setLevel(100);

   // Set a start time.

   p.setMediaTime(5 * SECS_TO_MICROSECS);

   // Guarantee that the player

   can start with the smallest latency.

   p.prefetch();

   // Non-blocking start

   p.start();
