            Bug ID: 781489
           Summary: dashdemux: Add support for tree-like SIDX
    Classification: Platform
           Product: GStreamer
           Version: unspecified
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: slomo at coaxion.net
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

For example
http://dash.akamaized.net/dash264/TestCases/1a/sony/SNE_DASH_SD_CASE1A_REVISED.mpd

What happens here is that there is a SIDX in the very beginning (with reftype
1) that points to other SIDX distributed over the whole file. The first one
directly following this initial SIDX. Each of these SIDX then points to a moof
(with reftype 0).

This can also be more than 2 levels from what I understand. Also each SIDX can
only point to things that are following (it can't point backwards).
