           Summary: [matroskademux] Segment warning when seeking in push
                    mode
    Classification: Platform

        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.freedesktop.org

     GNOME version: ---


With the following launch line, pressing the right arrow to seek forward will
cause the segment warning shown below. The video will seek back to the start
instead of seeking forward.

This happens for all Matroska videos I've tried.
This does not happen in pull mode.
