NodeJS video streaming server in connection with Android

I am working on an Android app which can stream videos from a NodeJS server.

I am new to video streaming. I first added a VideoView in an Android application as the following:

VideoView mVidView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mVidView = (VideoView)findViewById(R.id.myVideo);
    MediaController mediaCtrl = new MediaController(this);
    mediaCtrl.setAnchorView(mVidView);
    String vidAddress = "http://ift.tt/1Ab30Jw";
    Uri video = Uri.parse(vidAddress);
    mVidView.setVideoURI(video);
    mVidView.setMediaController(mediaCtrl);
    mVidView.start();

} 

It works well on Android Emulator. The video from the given url is being played and media controller can be used.

Next, I build a NodeJS http server and added a mp4 file(moviesample1.mp4) to the server. I then changed the vidAddress to:

    String vidAddress = "http://ift.tt/1wl5f0z";

where 10.0.2.2 is the ip of the build machine and 1337 is the port.

When I type the url above in a browser(e.g. Chrome), the movie is played within the browser. However, when I run the android app in emulator, the app shows a dialog which says "Can't play this video".

I realize that I may not have video streaming enabled on my NodeJS http server. I then searched for NodeJS streaming packages, such as vid-streamer(http://ift.tt/1wl5f0D)

I successfully installed vid-streamer and run an instance of a http server with it. I can see the movie within browser. However, when I change vidAddress in the android app to "http://ift.tt/1Ab32RF" while keeping the vid-streamer server running, the result is the same, "Can't play this video".

What should I do?
