            Bug ID: 791493
           Summary: qtmux: fmp4 sometimes sends last buffer twice (crash)
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: All
            Status: NEW
          Severity: major
          Priority: Normal
         Component: gst-plugins-good
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: matej.knopp at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

The second time the buffer is already released.

At the end of gst_qt_mux_pad_fragment_add_buffer

  if (G_UNLIKELY (force))
    goto flush;

This goes to flush: and after flushing continues through init:, where it
attempts to send the buffer twice.
