           Summary: [tsdemux] playback regression
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: bugzilla.gnome at gpost.dk
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


The attached file used to work using playbin2, but now it just reports EOS. It
works fine in mpegtsdemux which used to be the default demuxer.

A quick look using fakesink reveals this is likely a timestamp handling issue,
as the newsegment timestamps doesn't match the buffer timestamps.
