        var refreshVideo,videoReady;
        video.play();
        refreshVideo = setInterval(function(){
            if ( video.readyState === 4 ) {
                videoReady = true;                      
                if (video.play){
                    stopFunc();
                }               
            }else{  
                videoReady = false;
            }
            if(videoReady == true){
                video.play();
            }
        },500)
        function stopFunc(){
            clearInterval(refreshVideo);
        }
