索尼爱立信的v800手机可以支持流媒体的播放，使用非常简单。如果你曾经使用mmapi播放过声音或者做过照相应用的话，那么上手非常快。

        你要做的就是根据指定的url来创建一个player，然后启动这个player。url的格式如下：rtsp://myserver/myvideo.3gp。下面的代码例子演示了如何使用：
private void startstreaming(){
        try{
             myplayer = manager.createplayer("rtsp://myserver/myfile.3gp");
             myplayer.addplayerlistener(this);
             myplayer.realize();
              // grab the video control and set it to the current display.
              vc = (videocontrol)myplayer.getcontrol("videocontrol");
              if (vc != null) {
                myform.append((item)vc.initdisplaymode(vc.use_gui_primitive, null));
                // sets the display size of the video.
                vc.setdisplaysize(120,160); 
              }         
              myplayer.start();

         }catch(exception e){
                log("exception: " + e.tostring());
         }

    }
        我们需要注意的是进行连接服务器的时候必须在单独线程中处理，而不能在主线程。因为这样会堵塞系统。接下来你要做的就是构建一个支持rtsp的流媒体服务器，放置一个3gp格式的文件在服务器上。下面的代码演示了如何使用v800开发流媒体应用。
