GST Video overlay

[yPhil]

Hi,


I'm trying to get a video to display in a Gtk.Box() that I put in a 
paned container.

I'm passing the window handle - I'm getting it from the widget in the 
realize callback - to the player class:

     def __on_sync_message(self, bus: Gst.Bus, message: Gst.Message) -> 
None:
         if message.get_structure().get_name() == "prepare-window-handle":
             image_sink = message.src
             image_sink.set_property("force-aspect-ratio", True)
             image_sink.set_window_handle(self.__xid)

But that creates an overlay that covers the *whole* window

Is there a way to avoid the creation of the overlay ?

There seems to be a way to explicitly create a videosink then wait for a 
buffer signal to somehow direct the playbin to it, then get a Gtk 
container to display it "directly" and I'd really like to know how to do 
that.

But if the overlay is mandatory, and maybe it is (my app needs to be 
able to display the video in - real - full screen so it probably is) 
then how can I prevent it to cover the whole window (not just the paned 
container, the other widgets as well)?

I hope I'm making sense, thank you for you patience.
