           Summary: [gdppay] Sending a duplicated newsegment event for
                    every tag event
    Classification: Platform
           Product: GStreamer
           Version: 0.10.13
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: Normal
         Component: gst-plugins-base
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: slomo at circular-chaos.org
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


Currently gdppay resets the streamheader for every tag event because the tag
events are part of the streamheader. This results in a new "streamheader
packet" to be sent downstream, which also includes the current segment as
newsegment event.

On the depayloading side these additional newsegment events are depayloaded as
usual and are causing confusion downstream because they always open a new
segment.

Simple way to reproduce this is:

gst-launch-0.10 -v videotestsrc num-buffers=100 ! xvidenc ! mpeg4videoparse !
gdppay ! gdpdepay ! fakesink

Just look at all the newsegment events that appear in fakesink. From the debug
logs these happen because of the tag events sent by mpeg4videoparse.
