Youtube API player chrome extension

Question

I'm a newbie using YouTube API player.

I'm building a chrome extension to work with YouTube's API. In order to use the player, I have created a method in which I make this:

popup.js :

   jQuery(document).ready(function()

    {    

   Player();
    });

 // Creating the player
 function Player(){
   var tag = document.createElement('script');
   tag.src = "//www.youtube.com/iframe_api";
   var firstScriptTag = document.getElementsByTagName('script')[0];
   firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);  
 }


 function onYouTubeIframeAPIReady() {
    player = new YT.Player('player', {
      height: '1',
      width: '1',
      playerVars: {
                showinfo: '0',        
                controls: '0',
                autohide: '1',
                enablejsapi:'1',
                origin:"http://localhost/myapp"
        },
         events: {
        'onReady': IframeReady,
        'onStateChange': StateChange
        }
         });    
      }


      function IframeReady(event) {

player.addEventListener("onStateChange", "StateChange");
player.addEventListener("onError", "PlayerError");
player.setPlaybackQuality('hd720');
gettingInfo();
              }


 I get the music information (playlits) by using a search function, something like this:


    httpReq.open("GET","https://gdata.youtube.com/feeds/api/videos/-/Music/?v=2&alt=json&orderby="+"relevance"+"&start-index="+"1"+"&max-results="+"10"+"&q="+query);

Aforementioned function works perfect! I got the entire playlist. The problem is when I try to play the video action (playlist), the player seems does not work.

By using Inspect function from chrome extension I got this warning:

Failed to load resource chrome-extension://www.youtube.com/iframe_api

I have tried to fix this problem doing the following things:

1. By putting on manifest file this:

     "content_security_policy": 
      "script-src 'self' 'unsafe-eval'; https://www.youtube.com/player_api https://s.ytimg.com/yts/jsbin/www-widgetapi-vfljlXsRD.js; object-src 'self'"
   

2. By putting on popup.html this:

       <script type="text/javascript" src="//www.youtube.com/iframe_api"></script>
   

Can anyone tell me please How can I resolve this problem.

Thank you very much.
