Why does YouTube JavaScript Player API open a different URL than the one in my code, and just play the first video of a playlist?

It is my first post, I hope I respected all the rules.

I am trying to publish on a page of my website a: shuffle / muted / autoplay YouTube playlist.

I used the method AS3, with SWFObject.

Everything worked fine with the following code, but since few weeks, the player doesn't detect my playlist and just plays the first video.

In the code, the URL is: https://www.youtube.com/v/HuIGf4IJzdM&**list=PLo**-QIlIZx6myBxEysxrWoE-f58-psKGji

But when I open the page of the page, it open the following link: https://www.youtube.com/v/HuIGf4IJzdM&**list=o**-QIlIZx6myBxEysxrWoE-f58-psKGji

Here is the code which, if I am not wrong, works fine precedingly:

<script src="https://www.google.com/jsapi"></script>
<script src="https://ajax.googleapis.com/ajax/libs/swfobject/2.2/swfobject.js"></script>
<div id="ytapiplayer">You need Flash player 8+ and JavaScript enabled to view this video.</div>
<script type="text/javascript">
google.load("swfobject", "2.2");
function onYouTubePlayerReady(playerId) {
ytplayer = document.getElementById("myytplayer");
ytplayer.playVideo();
ytplayer.setShuffle(true);
ytplayer.mute();
}
var params = {allowScriptAccess: "always" , allowFullScreen : "true"};
var atts = { id: "myytplayer" };

swfobject.embedSWF("https://www.youtube.com/v/HuIGf4IJzdM&list=PLo-QIlIZx6myBxEysxrWoE-f58-psKGji&index=0&feature=plpp_play_all?enablejsapi=1&playerapiid=ytplayer&allowFullScreen=true&version=3&loop=1&autohide=1",
"ytapiplayer", "50%", "50%", "10", null, null, params, atts)
</script>

Thank you a lot if someone can help me to find the solution to this problem!

I finally found an alternative way to make it work with an iframe.

Here is the code :

<div id="player"></div>

<script>

  var tag = document.createElement('script');

  tag.src = "https://www.youtube.com/iframe_api";
  var firstScriptTag = document.getElementsByTagName('script')[0];
  firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

  var player;
  function onYouTubeIframeAPIReady() {
    player = new YT.Player('player', {
      height: '100%',
      width: '100%',
      events: {
        'onReady': onPlayerReady
      }

    });
  }

  function onPlayerReady(event) {

    event.target.loadPlaylist({'listType': 'playlist',
                               'list': 'PLo-QIlIZx6myBxEysxrWoE-f58-psKGji',
                               'index': '0'
                              });
      event.target.mute();
      event.target.setLoop(true);
    setTimeout( function() { 
        event.target.setShuffle(true); 
    }, 2000);
      }
</script>

Thank you for the help :-)
