StageWebView YOUTUBE VIDEO

I'm using StageWebView to watch a few YouTube videos.

Everything works great using Test Movie.

No problem in local situation but when I put the IPA on my device, I just get a white screen where the video should be.

Same thing if I load a simply URL as google for exemple...it's OK

It seems very simple yet I'm not finding anything on the web to help me out...

My code

<?xml version="1.0" encoding="utf-8"?> <s:View xmlns:fx="http://ns.adobe.com/mxml/2009"                     xmlns:s="library://ns.adobe.com/flex/spark"                     title="Player"                     viewActivate="init()">   <fx:Script>                     <![CDATA[                               import flash.net.navigateToURL;                               import mx.events.FlexEvent;                               import spark.events.ViewNavigatorEvent;                               protected var webView:StageWebView = new StageWebView();     protected function init():void                               {                                         var webView:StageWebView = new StageWebView();                                         webView.stage = this.stage;                                         webView.viewPort = new Rectangle( 0, 100, this.stage.stageWidth, this.stage.stageHeight/2 );   //webView.loadURL( "http://www.google.com" );                                         webView.loadURL("http://www.youtube.com/v/xQIeRGW1T5E?version=3");                                         addEventListener(ViewNavigatorEvent.REMOVING, onRemove);                               }                               protected function onRemove(event:ViewNavigatorEvent):void{                                         this.webView.dispose();                               }                     ]]>   </fx:Script> </s:View>

Thanks for your help, I'm work on this since many hours
