           Summary: rtph264pay does not multiplex NAL7/8 into stream
    Classification: Platform
           Product: GStreamer
           Version: 1.4.0
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: marc.leeman at gmail.com

     GNOME version: ---


It is going to be a fuzzy bug description, since it is pretty difficult to get
into the situation (or at least the mechanics are not yet completely
understood).

Setup:

Bosh camera 7000HD -> multicast -> GStreamer -> multicast

The observervation is that in some cases, the multicast produced by GStreamer
does not contain NAL 7 or NAL 8 anymore (SPS/PPS).

Inspecting the stream produced by gst:

Since it is difficult to reproduce; I do not have the detailed logging of the
intermediate operation; but from what is logged; it looks as if the CAPS and
config data from the originating encoder is captured:

application/x-rtp, media=(string)video, payload=(int)35, clock-rate=(int)90000,
encoding-name=(string)H264, packetization-mode=(string)1,
profile-level-id=(string)4d401e,
sprop-parameter-sets=(string)"Z01AHppmBgG9gLUFAQUC\,aO48gA\=\=",
a-recvonly=(string)"", npt-start=(guint64)0, play-speed=(double)1,
play-scale=(double)1

The pipeline strips the stream to ES and builds it back up; the ES caps are
complete too:

video/x-h264, stream-format=(string)avc, alignment=(string)au,
codec_data=(buffer)014d401effe1000f674d401e9a660601bd80b50501050201000468ee3c80,
width=(int)768, height=(int)432, framerate=(fraction)0/1, parsed=(boolean)true,
pixel-aspect-ratio=(fraction)1/1

The camera uses RTSP with multicast; listening to the multicast of the camera
directly does show that the configuration data is sent in the stream (decoding
picks up).

As far as I know; I haven't seen it with any other camera than this one (might
be a general problem; I don't know).
