           Summary: gst_xoverlay_set_xwindow_id() causing lockups with
                    x(v)imagesink
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: jorn at openedhand.com

     GNOME version: Unspecified
   GNOME milestone: Unspecified


When calling gst_xoverlay_set_xwindow_id() during the 'prepare-xwindow-id'
signal in a thread different from the one where x(v)imagesink lives, occasional
lockups and/or X errors occur. I noticed flow_lock is locked whenever xwindow
is being touched, except in setcaps(), just after firing the
'prepare-xwindow-id' signal. Locking flow_lock there as well appears to fix the
problems.
