Playing youtube video randomly on element's background

Question

Currently, I'm using this jquery which gets youtube video and plays them in element's background.

I was provided with this code that will play single youtube video. But I would like to make a list of videos and play them randomly... I am not so good with Javascript at the moment, so I would really appreciated some help on this...

right now I have this....

I wanna make a list of videos and play them randomly like a shuffled playlist..

$(function() 
{ 
    var videos = ['xJvt2SDV7ck', 'x6DD1k4BAUg', 'xJvt2SDV7ck'];
    var index = Math.floor(Math.random() * videos.length);

    var Video_back = new video_background($("#bgvideo"), 
    {
        "position": "absolute", //Stick within the div
        "z-index": "-1",        //Behind everything
        "loop": true,           //Loop when it reaches the end
        "autoplay": true,       //Autoplay at start
        "muted": true,          //Muted at start
        "youtube": "videos[index]",   //Youtube video id
        "start": 0,                 //Start with 6 seconds offset (to pass the introduction in this case for example)
        "video_ratio": 1.333,      // width/height -> If none provided sizing of the video is set to adjust
        "fallback_image": "videos/main.jpg",    //Fallback image path
    });
});

Currently It only plays 1 video randomly selected from the list(single loop). I want to make it so that it will move on to another video when the first video finishes..

HELP WILL BE MUCH MUCH APPRECIATED! THANK YOU FOR YOUR TIME!

The following answer is based on the fact that there is no way of determining when a video has finished. The lengths are in milliseconds:

$(function() 
{ 
    var videos = 
    [ 
        { id : 'xJvt2SDV7ck', length : 60000 },
        { id : 'x6DD1k4BAUg', length : 125000 },
        { id : 'xJvt2SDV7ck', length : 166000 }
    ];

    function playNext()
    {
        var index = Math.floor(Math.random() * videos.length);

        alert( "Playing next movie => " + videos[index].id );

        var Video_back = new video_background($("#bgvideo"), 
        {
            "position": "absolute", //Stick within the div
            "z-index": "-1",        //Behind everything
            "loop": true,           //Loop when it reaches the end
            "autoplay": true,       //Autoplay at start
            "muted": true,          //Muted at start
            "youtube": videos[index].id,   //Youtube video id
            "start": 0,                 //Start with 6 seconds offset (to pass the introduction in this case for example)
            "video_ratio": 1.333,      // width/height -> If none provided sizing of the video is set to adjust
            "fallback_image": "videos/main.jpg",    //Fallback image path
        });

        setTimeout(function() 
        {
            playNext();
        }, videos[index].length);
    }

    playNext();
});
