Error while displaying RTP stream packets from udp port on Gstreamer

I am streaming a live webcam using VLC to darwin streaming server.

Then tried to play this live web cam feed on RTSP client using following

GST_DEBUG=2 gst-launch -vvv playbin uri=rtsp://172.19.91.21/channel.sdp

Everthing works fine. output is coming on gstreamer window.

I have reflect all the packest from DSS to RTSP client as well as on a udp_port. But when i tried to play RTP stream using following command

GST_DEBUG=2 gst-launch-0.10 -vvv udpsrc port=5000 multicast-iface="lo" multicast-group="172.19.91.20" buffer-size=1000000 caps="application/x-rtp, media=video, clock-rate=90000, encoding-name=H264" do-timestamp=false ! rtph264depay ! decodebin ! autovideosink

I am getting following errors

0:00:07.108734201 7874 0x89d2a90 ERROR ffmpeg :0:: non-existing PPS referenced 0:00:07.108803500 7874 0x89d2a90 ERROR ffmpeg :0:: non-existing PPS 0 referenced 0:00:07.108824183 7874 0x89d2a90 ERROR ffmpeg :0:: decode_slice_header error 0:00:07.108840903 7874 0x89d2a90 ERROR ffmpeg :0:: no frame! 0:00:07.108859244 7874 0x89d2a90 WARN ffmpeg gstffmpegdec.c:2299:gst_ffmpegdec_frame: ffdec_h264: decoding error (len: -1, have_data: 0)

Please guide me how to solve this problem.
