           Summary: Missing plugin for ONVIF IP Cameras
    Classification: Platform
           Product: GStreamer
           Version: 1.4.4
        OS/Version: Windows
            Status: UNCONFIRMED
          Severity: major
          Priority: Normal
         Component: gst-plugins
        AssignedTo: gstreamer-bugs at lists.freedesktop.org

Some IP Cameras follow Onvif protocols (a standard for surveillance cameras).
These usually have h.264 codecs. When trying to decode using playbin or
uridecodebin there is an error showing:

Missing element: VND.ONVIF.METADATA RTP depayloader

Using the following pipeline works:

$ gst-launch-1.0.exe rtspsrc location=rtsp://user:pass@0.0.0.0/rtspStream !
rtph264depay ! h264parse ! avdec_h264 ! autovideosink

However, if the camera's resolution is modified, the pipeline fails to detect
the correct resolution. Possibly the correct resolution information is found in
the metadata. 

VLC does successfully decode the rtsp stream.
