...MediaElement.js is a set of custom Flash plugins that mimic the HTML5 MediaElement API for browsers that don't support HTML5 or don't support the media codecs you're using. Instead of using Flash as a fallback, Flash is used to make the browser seem HTML5 compliant and enable codecs like H.264 (via Flash) on all browsers. In general, MediaElement.js supports IE11+, MS Edge, Chrome, Firefox, Safari, iOS 8+ and Android 4.0+. It is strongly recommended to read the entire documentation and check the demo folder to get the most out of this package.
