Smartface play video - smartface.io

Question

I added video component to page then after I wrote this code as follows. But not working. How can I run this?
Pages.Page1.Video1.playVideo(true, true, function() {
alert("playybackStarrted.")
}, function() {
alert("video Initialized.")
}, function() {
alert("playyback Completed.")
}, function() {
alert("Error")
});
I tried this. I defined contentUrl as video.mp4. But I can't run this.
var video1 = new SMF.UI.Video({
top : "10%",
left : "10%",
width : "80%",
height : "40%",
controlStyle : SMF.UI.VideoControlStyle.embedded,
contentUrl : "video.mp4"
});

Answer 1

I added video dynamically and it runs fine as follows:
var video1 = new SMF.UI.Video({
top : "10%",
left : "10%",
width : "80%",
height : "40%",
controlStyle : SMF.UI.VideoControlStyle.embedded,
contentUrl : "..."
});
Pages.Page1.add(video1);
var btnPlay = new SMF.UI.TextButton({
top : '52%',
left : '10%',
width : "80%",
height : "10%",
text : "Play Video",
onPressed : function (e) {
video1.playVideo(true, true, function () {
alert("playybackStarrted.")
}, function () {
alert("video Initialized.")
}, function () {
alert("playyback Completed.")
}, function () {
alert("Error")
});
}
});
Pages.Page1.add(btnPlay);
