            Bug ID: 757563
           Summary: audiomixer has issues with looping
    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: ensonic at sonicpulse.de
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

Despite a test that should cover this in real world apps, audiomixer
(aggregator) goes crazy when looping (gst_aggregator_do_seek):

I can play once with a segmented+flushing seek. When handling segment_done and
sending another segmented seek (non flushing), I get this log forever, until I
stop the pipeline.
