How to stream video with Android Emulator

[ngubk]

Nice to meet you all!!! I'm still new to Android. I try to write a simple program to stream video but the returned message is always::Sorry, this video cannot be played". Here's the code:

public class Video_testActivity extends Activity {    public static VideoView mVideoView;
    public static MediaController mediaController;

    public static String path_uri = "rtsp://localhost:554/sample_100kbit.mp4";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mVideoView = (VideoView) findViewById(R.id.VideoView);

        mediaController = new MediaController(this);
        mediaController.setAnchorView(mVideoView);

         Uri video = Uri.parse(path_uri);
  
         mVideoView.setMediaController(mediaController);
         mVideoView.setVideoURI(video);
         //videoView.setVideoPath(path);
         mVideoView.start();
    }
}

"rtsp://localhost:554/sample_100kbit.mp4" is the address of the streamed video. I can view it just fine using vlc
