            Bug ID: 758949
           Summary: qtmux can't handle missing DTS
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Mac OS
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: samduke474 at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

So using an rtsp connection over TCP I end up with no DTS in my stream. When I
try to save this to an mp4 file, I get an corrupted mp4. Switching to UDP works
fine.

My setup is described in this bug:
https://bugzilla.gnome.org/show_bug.cgi?id=758932

To summarise, 

gst-rtsp-server-1.0/examples/test-launch "( videotestsrc is_live=true ! x264enc
! video/x-h264,width=1296,height=972,framerate=25/1 ! h264parse ! rtph264pay
pt=96 name=pay0 )"


./gst-launch-1.0 -e rtspsrc location=rtspt://127.0.0.1:8554/test ! rtph264depay
! h264parse ! mp4mux ! filesink location=~/Downloads/localtest1.mp4

The file will not play and shows only the first frame.

I believe the error is in 'gst_qt_pad_adjust_buffer_dts'.
