Mac Cocoa WebView (WebKit) - YouTube videos show as black squares but audio works

[gwelmarten]

Hi

I am trying to access youtube.com through a WebKit WebView in my native Mac App.

The problem is that YouTube videos just show as black squares (see image below). However, if I click them they start to play (but stay black) - the sounds starts. I can also right click and the YouTube right click menu comes up (with things like 'Stats for Nerds').

Does anyone know what is happening here?

I use the standard WebView component, dragged in in Interface Builder. In my header I have the standard:

IBOutlet WebView *firstWebView;

and in my .m the standard:

[firstWebView setHidden:FALSE];
[[firstWebView mainFrame] loadRequest:[NSURLRequest requestWithURL: [NSURL URLWithString:@"http://youtube.com"]]];

The same thing happens when I access a site with an embedded YouTube video.

Thanks!

Sam

[myWebView setLayerUsesCoreImageFilters:YES];
