流低延迟RTSP视频的ffmpeg到Android

我想从流的Ubuntu 12.04 PC现场摄像头视频与奇巧Android设备。到目前为止，我已经写配置ffserver的文件接收FFM饲料，并通过RTSP协议播放。我能看在同一个局域网其他计算机上ffplay流。

I am trying to stream live webcam video from Ubuntu 12.04 PC to android device with KitKat. So far I've written ffserver config file to receive ffm feed and broadcast it through a rtsp protocol. I am able to watch the stream on the other computer in the same LAN with ffplay.

如何观看在Android设备上的数据流？下面code效果很好，当网络摄像头图像流与VLC，但它不与ffmpeg的：

How to watch the stream on the android device? The following code works well when the webcam image is streamed with vlc but it doesn't with ffmpeg:

public class MainActivity extends Activity implements MediaPlayer.OnPreparedListener,
        SurfaceHolder.Callback {

    final static String RTSP_URL = "rtsp://192.168.1.54:4424/test.sdp";

    private MediaPlayer _mediaPlayer;
    private SurfaceHolder _surfaceHolder;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // Set up a full-screen black window.
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        Window window = getWindow();
        window.setFlags(
                WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        window.setBackgroundDrawableResource(android.R.color.black);
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
        setContentView(R.layout.activity_main);

        // Configure the view that renders live video.
        SurfaceView videoView =
                (SurfaceView) findViewById(R.id.videoView); //where R.id.videoView is a simple SurfaceView element in the layout xml file
        _surfaceHolder = videoView.getHolder();
        _surfaceHolder.addCallback(this);
        _surfaceHolder.setFixedSize(320, 240);
    }
    @Override
    public void surfaceCreated(SurfaceHolder surfaceHolder) {
        _mediaPlayer = new MediaPlayer();
        _mediaPlayer.setDisplay(_surfaceHolder);
        Context context = getApplicationContext();
        Uri source = Uri.parse(RTSP_URL);
        try {
            // Specify the IP camera's URL and auth headers.
            _mediaPlayer.setDataSource(context, source);

            // Begin the process of setting up a video stream.
            _mediaPlayer.setOnPreparedListener(this);
            _mediaPlayer.prepareAsync();
        }
        catch (Exception e) {}
    }
    @Override
    public void onPrepared(MediaPlayer mediaPlayer) {
        _mediaPlayer.start();
    }
}

我ffserver.config文件：

My ffserver.config file:

HTTPPort 8090
RTSPBindAddress 0.0.0.0
RTSPPort 4424
MaxBandwidth 10000
