GStreamer PlatformVideoWindow needs an API to prepare the widget before applying the overlay

• Component: Media
• Status: RESOLVED FIXED

[Philippe Normand]

On Mac OSX, the osxvideosink sends a message on the GStreamer bus which includes a pointer to its internal NSView. Application-side needs to retrieve and use it before calling the XOverlay set_window_handle function.

So I propose to add a simple "prepare(GstMessage*)" method in PlatformVideoWindow for this purpose.
On Gtk and EFL this would be an empty implementation.

I'm not sure what an appropriate name for this method should be (perhaps prepareForOverlay?), but I think that prepare is not descriptive enough.

The name prepare(...) seems a little ambiguous. I would prefer something a bit more descriptive.

> WebCore/platform/graphics/gstreamer/PlatformVideoWindowEfl.cpp:40
> +    notImplemented();

An empty implementation is different than notImplemented(). This should just be empty.

> WebCore/platform/graphics/gstreamer/PlatformVideoWindowGtk.cpp:69
> +    notImplemented();

Same here.
