WP Video (mediaelementjs) force autoload

force-autoplay.js

      $(window).on('load', function() {
        var player = $('video.wp-video-shortcode').data('mediaelementplayer');
        player.options.success = function(media, dom) {
          if (media.pluginType === 'flash') {
              media.addEventListener('canplay', function() {
                  // Player is ready
                  media.play();
              }, false);
          } else {
            media.play();
          }
          var force = setInterval(function() {
            if (media.paused) {
              media.play();
            } else if (media.paused === false) {
              clearInterval(force);
            }
          }, 500);       
        };
      });

Very good.
