           Summary: rtph264pay doesn't meet the minimum requirements of
                    RFC3984
    Classification: Platform
           Product: GStreamer
           Version: 1.1.4
        OS/Version: All
            Status: UNCONFIRMED
          Severity: critical
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: wigert at gmail.com
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


In section 5.4 of rfc3984 it is stated that packetization-mode 0 is required to
be implemented. This means sending single NAL, not fragmented NALs (FU-A). In
gstreamer there seems to be no way to set packetization-mode, and no way to
force x264enc to output smaller packets than the mtu in rtph264pay. This means
that the requirement of packetization-mode 0 is impossible to fulfill in the
current implementation.

If anyone has a workaround for this I'd be thrilled to hear about it!
