YouTube - how to play video only without audio?

I have a video which i want to play in the website like

www.paypal.com
playing a video without audio on landing.

Is this a BUG? But when i tried as following, i cant mute the audio at all, even the volume parameter is set to 0.

How can i mute the audio?

<iframe id="bg" src="https://www.youtube.com/embed/VfcZsyhUJ48?autoplay=1&controls=0&loop=1&showinfo=0&modestbranding=1&disablekb=1&enablejsapi=1&rel=0" frameborder="0" volume="0"
style="width: 100%;height:100%;
opacity: 0.80 !important;"
allowtransparency="true"></iframe>

}


or

onStateChange: function(e){
var id = 'qzZuBWMnS08';

if(e.data === YT.PlayerState.ENDED){
player.loadVideoById(id);
}
}

Answer
Well, the volume="0" no longer seems to work but the code below does:
    <!-- 1. The <iframe> (and video player) will replace this <div> tag. -->
    <div id="player"></div>
    <script>
      // 2. This code loads the IFrame Player API code asynchronously.
      var tag = document.createElement('script');
      tag.src = "https://www.youtube.com/iframe_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 onYouTubeIframeAPIReady() {
        player = new YT.Player('player', {
          height: '195',
          width: '260',
          videoId: 'h3P1OR9gg2Y',
          events: {
            'onReady': onPlayerReady,
            'onStateChange': onPlayerStateChange
          }
        });
      }
      // 4. The API will call this function when the video player is ready.
      function onPlayerReady(event) {
           event.target.setVolume(0);
       event.target.playVideo();
      }
      // 5. The API calls this function when the player's state changes.
      //    The function indicates that when playing a video (state=1),
      //    the player should play for six seconds and then stop.
      var done = false;
      function onPlayerStateChange(event) {
        if (event.data == YT.PlayerState.PLAYING && !done) {
    //      setTimeout(stopVideo, 6000);
                  done = true;
        }
           event.target.setVolume(0);
      }
    </script>
