            Bug ID: 755251
           Summary: gtksink: Rework threading around GtkWindow creation
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: tsaunier at gnome.org
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

Currently, in gtkglsink, we create a GtkWindow in ->start which can potentially
happen from any thread, which is wrong as Gtk is not MT safe.

Also creating the window between NULL to READY is suboptimal from a user
perspective as we might be doing that state change just to check whether we can
use the element or not (and we do not expect a Window to raise at that point!).
