Interface Player

All Superinterfaces:

Controllable

public interface Player extends Controllable

---

原意： Player controls the rendering of time based media data. It provides the methods to manage the Player's life cycle, controls the playback progress and obtains the presentation components. 译文： Player控制 媒体数据的表现时间 。 它提供 的方法 来管理 Player 的生命周期 ，控制 播放进度 和 取得 的 表示组件 。

A Player can be created from one of the Manager's createPlayer methods. 

一个Player对象是通过Manager的一个方法创建产生。

例如：// 构造播放器对象
   player = Manager.createPlayer(is, "video/mpeg");//Video/3gpp

播放视频五个步骤：

  

   // 读取本地媒体资源，转化为输入流对象
    InputStream is = this.getClass().getResourceAsStream("/test-mpeg.mpg");   //注意此处的格式

   // 构造播放器对象
   player = Manager.createPlayer(is, "video/mpeg");//Video/3gpp                       //注意此处格式设置
   
   // 播放器序列化
   player.realize();
   
   // 添加视频控制器
   VideoControl vc = (VideoControl)player.getControl("VideoControl");
   
   // 设置视频播放模式
   Item item = (Item)vc.initDisplayMode(VideoControl.USE_GUI_PRIMITIVE, null);
   
   item.setLayout(Item.LAYOUT_TOP);
   form.append(item);
   display.setCurrent(form);
   
   // 开始播放
   player.start();
