  GStreamer | gst-plugins-bad | 1.4.1

           Summary: compositor: performance degrades over time
    Classification: Platform
           Product: GStreamer
           Version: 1.4.1
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: jan.steffens at gmail.com
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


Comparing the following two pipelines:

gst-launch-1.0 videotestsrc ! videomixer ! progressreport ! fakesink

gst-launch-1.0 videotestsrc ! compositor ! progressreport ! fakesink

The one using compositor both grows in memory use and slows down over time. It
ends up spending most of its time in g_source_iter_next.
