背景视频并不总是在播放

Question

https://solarshield.co.uk/ 在本网站主页的背景中播放的视频并不总是播放，但如果保持清爽将播放。任何帮助或建议将不胜感激。不太清楚提供有关此事的其他信息。

<script type="text/javascript" src="templates/solarshield/js/okvideo.js"></script>
<script>
var isMobile = {
    Android: function() {
        return navigator.userAgent.match(/Android/i);
    },
    BlackBerry: function() {
        return navigator.userAgent.match(/BlackBerry/i);
    },
    iOS: function() {
        return navigator.userAgent.match(/iPhone|iPad|iPod/i);
    },
    Opera: function() {
        return navigator.userAgent.match(/Opera Mini/i);
    },
    Windows: function() {
        return navigator.userAgent.match(/IEMobile/i);
    },
    any: function() {
        return (isMobile.Android() || isMobile.BlackBerry() || isMobile.iOS() || isMobile.Opera() || isMobile.Windows());
    }
};

/* only play video on desktop devices RB200exAR1M */
trueMobile = isMobile.any();

jQuery.okvideo({ source: '7JE4TDyXZ10',
