Embedding Wistia video in a Mobile App developed using Titanium

Question

We are developing a Mobile App using the Titanium framework, we need to embed some videos in one of the screens. Appcelerator API documentation that I am following is located here. My code looks as follows, currently it shows a blank screen :

var welcomeWin = Ti.UI.createWindow({
    title:'Welcome Video',
    backgroundColor:'#fff' 
});


var videoplayer = Titanium.Media.createVideoPlayer({
    top:2,
    autoplay:true,
    height:300,
    width:300,
    url:'https://fast.wistia.net/embed/iframe/thewistiaurl',
    mediaControlStyle:Titanium.Media.VIDEO_CONTROL_DEFAULT,
    scalingMode:Titanium.Media.VIDEO_SCALING_ASPECT_FIT
});


welcomeWin.add(videoplayer);
