Error during RTSP streaming using gstreamer

I'm using gstreamer to do RTSP streaming. To achieve that I downloaded the gst-rtsp-server setup from https://gstreamer.freedesktop.org/src/gst-rtsp-server/ . I compiled the code successfully. I could start the gstreamer rtsp server using (server side code )

./test-launch "(videotestsrc ! x264enc ! rtph264pay name=pay0 pt=96)"

After this server starts listening at port 8554

At the receiver side (client) , to play the streamed video I'm using

gst-launch-1.0 -v rtspsrc location=rtsp://127.0.0.1:8554/test

But I'm getting following error at server side :

    ** Message: state PLAYING media 0xb04160
    ** Message: 0xb04160: got message type new-clock
    0:00:04.375120259 17746       0xa74b00 WARN                     bin gstbin.c:2395:gst_bin_do_latency_func:<media-pipeline> did not really configure latency of 0:00:00.000000000

RTSP request message 0xaa0888

Kindly tell me, what gstreamer elements has to be used at client side ? I could play the streaming video successfully using VLC (Open VLC -- > Media --> Open Network Streaming -- > RTSP://path.... )

Note: Im' using gstreamer-1.0 I'm using Ubuntu PC for client and server setup.

I was able to run this with below command:

gst-launch-1.0 -v rtspsrc location=rtsp://127.0.0.1/test caps="application/x-rtp, media=(string)video, payload=(int)96, clock-rate=(int)90000, encoding-name=(string)H264" ! rtph264depay ! decodebin ! videoconvert ! autovideosink

At server side you are encoding the data using x264enc, so at client side you have to decode it and then have to play it.

Try this pipeline, It will work

gst-launch-1.0 -v rtspsrc location=rtsp://127.0.0.1:8554/test ! rtph264depay ! h264parse ! avdec_h264 ! videoconvert ! xvimagesink
