Autoplay youtube video on mobile

Question

I wonder how I can put the youtube video in autoplay on mobile, because it is not working, on mobile it is not in autoplay, do not run the video without having to press.

My Script.

   <script>      
          // 2. This code loads the IFrame Player API code asynchronously.
          var tag = document.createElement('script');
          tag.src = "http://www.youtube.com/player_api";
          var firstScriptTag = document.getElementsByTagName('script')[0];
          firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

          // 3. This function creates an <iframe> (and YouTube player)
          //    after the API code downloads.
          var player;
          function onYouTubePlayerAPIReady() {
            player = new YT.Player('player', {
              playerVars: { 'modestbranding':0,'autoplay': 1, 'controls': 0,'autohide':2,'wmode':'opaque','showinfo':0,'rel':0,'loop':0,'disablekb':1,'playlist':1,'playerapiid':0,'enablejsapi':1,'list':1,'listType':1, 'iv_load_policy':3 }, 
              videoId: 'RC0Wrd12sno',
              events: {
                'onReady': onPlayerReady
                }


            });


          }


          // 4. The API will call this function when the video player is ready.
          function onPlayerReady(event) {
            event.target.mute(true);
             event.target.loadPlaylist(['RC0Wrd12sno']);
             event.target.setLoop(true); 
          }


</script>
