I want to play live streaming you tube channel in windows phone 8 app.
for this I searched a lot and at last I got this,
I Installed the Visual Studio Extension SDK (Microsoft.PlayerFramework.WP8.vsix) .
And then I installed the Microsoft Smooth Streaming Client.
and added the required dll's like smoothstreaming.dll, mediaplayer.framework , mediaplayer.framework.adaptive ..etc

and in mainpage.xaml I added the

xmlns:mmppf="clr-namespace:Microsoft.PlayerFramework;assembly=Microsoft.PlayerFramework"

    xmlns:adaptive="clr-namespace:Microsoft.PlayerFramework.Adaptive;assembly=Microsoft.PlayerFramework.Adaptive"

and after that I created media element by below

<Grid x:Name="LayoutRoot" Background="Transparent">
    <mmppf:MediaPlayer Source="https://www.youtube.com/watch?v=LIuk1qu0RlU">
       
</Grid>

the problem is after executing it I am unable to see the video streaming I dont know why I am not getting any errors it is building successfully .
Anybody help me, Thank you.
