           Summary: qtmux: add support for mp4 timed text
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.freedesktop.org

     GNOME version: ---


First patch changes the way sample delta is calculated. The variable is called
duration, but it is used as timestamp delta for samples so it probably should
be calculated as dts (or pts if no dts are present) delta instead from
duration. Otherwise sparse streams and streams with discontinuities will have
wrong timestamps.
