Youtube videos do not open in full screen

I am using youtube as a music player and every time someone accesses on iOS devices it opens the video in full screen. Follow my code with playsinline.

var buildPlayer = function(videoUrl)
{
     playerLoading = true;

     player = new YT.Player(attrs.container, {
         height: '200',
         width: '200',
         videoId: getIdFromUrl(videoUrl),
         playerVars: {
             enablejsapi: 1,
             playsinline: 1,
             html5: 1,
         },
         events: {
             'onReady': onPlayerReady,
             'onStateChange': onStateChange
         }
     });
}
