PhotoFrame is displayed when youtube videos playing in WebBrowser

I have written code for playing youtube videos in webbrowser.
Xaml code:
<phone:WebBrowser x:Name="webBrowser" Height="411" IsScriptEnabled="True" Margin="10,100,78,0" />
Xaml.cs code:
Movie movie;
public VideoPage()
{
InitializeComponent();
var app = App.Current as App;
movie = app.selectedMovie;
string video =movie.MovieWatchLink;
this.webBrowser.Navigate(new Uri(video));
}
When I run this code at first white color PhotoFrame is displaying as shown in below figure.
And when we tap it.Movie starts playing in nativeplayer.And when we want to move back to movies list also this photoframe is displaying.
Please anybody help me how can I remove this.I searched my level best eventhough I didnt get any solution. Please help me how can I immediately play after selecting the movie.
ManyThanks in Advance
You can try collapsing the visibility of the webBrowser until the video starts streaming in the native player if we can get any handle of media being played in our code.or else you can try showing a thumbnail image related to the video until it starts to stream in player.
Showing thumbnail will be a better choice.

Controls for Youtube Chromeless Player In Flash

I'm tearing my hair out trying to add controls such as pause and volume to my Chromeless Youtube Player in Flash with actionscript 3, tried working with the reference that google provide but it still doesn't work. Here's what I tried, can anyone tell me where I'm going wrong?
function pauseVideo() {
if (player) {
player.pauseVideo();
}
}
pauseBtn.addEventListener(MouseEvent.CLICK,pauseVideo);
Thanks
How I understand you are trying to integrate youtube's player into your application. Take a look at this example it may help you and check with the documentation if you are loading correctly their player and it's fully loaded when you are trying to access it, first example
*I would like to help you more but I don't know how you instantiate the player

return frame number video js?

Does anyone know how I can return what frame the video would be on at a certain point ?
so for example the video is playing and I press a js button ive made and it returns the current frame the video is on and prints it on screen .
There's no way to know the exact frame of the video from the html5 video element, but if you know the frame rate (e.g. 30 fps) up front you could do the calculation.
var frame = Math.floor(myPlayer.currentTime() * frameRate);
