GstXOverlay interface methods not available

[Emmanuel Rodriguez <emmanuel rodriguez gmail com>]

Hi,

Is it possible that the GstXOverlay interface is not available in the Gstreamer Perl bindings?

I was playing around with Gstreamer's Perl API and I tried to port the Vala example "Vala GStreamer Video Example" [1]. In that example a "xvimagesink" is embedded in a Gtk2 window, or so I think as I don't have vala. This is acheived through the following Vala code:

    private void on_play () {
        ((XOverlay) this.sink).set_xwindow_id (
                Gdk.x11_drawable_get_xid (this.drawing_area.window));
        this.pipeline.set_state (State.PLAYING);
    }

When I run the corresponding Perl code (I've attached a sample script showing the problem):
    $sink->set_xwindow_id($canvas->window->get_xid);

I get the following error:
    Can't locate object method "set_xwindow_id" via package "Glib::Object::_Unregistered::GstXvImageSink" at ./gst-video-sample.pl line 48.


Is there another way to do the same? Maybe I'm not using the right function calls.
