           Summary: avoid x event thread if not needed
    Classification: Desktop
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: Normal
         Component: gst-plugins-base
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: ensonic at sonicpulse.de

The attached patch starts/stops the event thread in xvimagesink as needed. This
reduces context switches. Right now the thread polls the event 20 times a
second.

I have this applied in my system and see no regression so far. Would be nice to
get a review and some testing.
