MediaPlayer流式传输错误

Question

我想从我的电脑上的VLC流式传输到我的Android设备上运行Android 4.0.3，但不知何故，它只是不会工作，我搜索了互联网，它的错误意味着我正在使用错误的格式。不过，我已经有了正确的格式，不应该发生这种错误。所以我希望你们能帮我解决问题。

MediaPlayer player; 
SurfaceHolder holder; 
SurfaceView surfaceView; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    surfaceView = (SurfaceView) findViewById(R.id.rtspStream); 
    holder = surfaceView.getHolder(); 
    holder.addCallback(this); 
    player = new MediaPlayer(); 
    player.setOnErrorListener(this); 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.activity_main, menu); 
    return true; 
} 
@Override 
public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2, int arg3) { 
    // TODO Auto-generated method stub 

} 
@Override 
public void surfaceCreated(SurfaceHolder arg0) { 
    try 
    { 
     if(holder.equals(holder)) 
     { 
      player.setDataSource(this,Uri.parse("rtsp://192.168.0.3:8080/test.sdp")); 
      player.setDisplay(holder);   
      player.prepare(); 
      player.start(); 
     } 
    } 
    catch(Exception e){ 
     Log.e("MEDIA", e.toString()); 
    } 
} 
@Override 
public void surfaceDestroyed(SurfaceHolder arg0) { 
    // TODO Auto-generated method stub 
} 
@Override 
public boolean onError(MediaPlayer arg0, int arg1, int arg2) { 
    if(arg0.equals(player)){ 
     if(arg1 == MediaPlayer.MEDIA_ERROR_UNKNOWN){ 
      Log.d("onError","extra "+arg2); 
     } 

    } 
    return false; 
} 

这是我的测试类。 我logcat的看起来像这样

我与运行VLC终端：

Answer 1

从直播时互联网使用prepareAsync，而不是准备和调用onPrepared方法：

player.setOnPreparedListener(new StreamPlayerListener());   
player.prepareAsync(); 

而且StreamPlayerListener类：

private class StreamPlayerListener implements OnPreparedListener { 

    @Override 
    public void onPrepared(MediaPlayer mp) { 
     player.start(); 
    } 
}
