Script Not Working

I had originally posted this directly on GitHub (https://github.com/videojs/video.js/issues/1635#event-187631860) and just now realized I should have posted here.

You can check out my problem page by going to https://socialsipn.com/test-page/

In the WordPress page, I have the following code:

<div class="intro-video">
     [videojs controls="false" preload="auto" id="sipnvideo" youtube="https://youtu.be/5lQqBG8B2DQ"][/videojs]
     <script type="text/javascript">
          <!--//--><![CDATA[//><!--
               $(document).ready(function() {
                    RunMainScreenVideo();
               });
          //--><!]]>
     </script>
</div>

The RunMainScreenVideo script is below – it gets to the var myPlayer = videojs(… line but never gets any further. The script is registered properly – the commented out alerts worked – but I cannot get the video player to initialize. Instead I keep getting “videojs undefined” exceptions.

I attempted to add the CDN CSS and JS links in my Header.php file but that did not help. I have also taken out and added the video link back in but that does not make any difference.

What am I doing wrong?

Thanks!

function RunMainScreenVideo() {
     var isMobile = false;

    if (screen.width < 699) {
        isMobile = true;
    }

    //if (isMobile) {
    //    alert("Is still reading Mobile!!!");
    //}
    //else {
    //    alert("is NOT mobile!!!");
    //}

    var myPlayer = videojs("sipnvideo");  //Stops here
    alert("Loaded player");

    //Load the correct video
    if (isMobile) {
        alert("is mobile");
        myPlayer.src({ type: "video/youtube", src: "https://youtu.be/1LVyLVLqdA4" });
    }
    else {
        alert("is NOT mobile");
        myPlayer.src({ type: "video/youtube", src: "https://youtu.be/feuItfTRqTs" });
    }

    //Start playing the video.
    myPlayer.play();

    //Hangout until the video ends
    while (!myPlayer.ended()) { }

    //Redirect to the main home page
    window.location = "https://socialsipn.com/secure-online-communications/";
}
