ビデオの参照を削除しました。試してみてください:

(function(window, document){
        var $ = function(selector,context){return(context||document).querySelector(selector)};

        var iframe = $("iframe"),
            domPrefixes = 'Webkit Moz O ms Khtml'.split(' ');

        var fullscreen = function(elem) {
            var prefix;
            // Mozilla and webkit intialise fullscreen slightly differently
            for ( var i = -1, len = domPrefixes.length; ++i < len; ) {
              prefix = domPrefixes[i].toLowerCase();

              if ( elem[prefix + 'EnterFullScreen'] ) {
                // Webkit uses EnterFullScreen for video
                return prefix + 'EnterFullScreen';
                break;
              } else if( elem[prefix + 'RequestFullScreen'] ) {
                // Mozilla uses RequestFullScreen for all elements and webkit uses it for non video elements
                return prefix + 'RequestFullScreen';
                break;
              }
            }

            return false;
        };              
        // Webkit uses "requestFullScreen" for non video elements
        var fullscreenother = fullscreen(document.createElement("iframe"));

        if(!fullscreen) {
            alert("Fullscreen won't work, please make sure you're using a browser that supports it and you have enabled the feature");
            return;
        }

        $("#fullscreeniframe").addEventListener("click", function(){
            // iframe fullscreen and non video elements in webkit use request over enter
            iframe[fullscreenother]();
        }, false);
    })(this, this.document);
