The errors seem to indicate that it failed to connect to RTSP server.
Confirm the stream is available and can be understood and played with:

gst-discover-1.0 -v rtsp://user:pass@xxx.xxx.xxx.xxx/cam/realmonitor?channel=1&subtype=0

gst-play-1.0 -v rtsp://user:pass@xxx.xxx.xxx.xxx/cam/realmonitor?channel=1&subtype=0

Thanks for the reply

I have tried with what you suggest but With gst-discoverer-1.0 i am response Analyzing URI timed out and gst-play-1.0 does not providing any output

but the same stream works fine with vlc media player

Not sure, but if your username or password contains some special characters, you may enclose the uri into double quotes:

gst-discover-1.0 -v "rtsp://user:pass@xxx.xxx.xxx.xxx/cam/realmonitor?channel=1&subtype=0"

gst-play-1.0 -v "rtsp://user:pass@xxx.xxx.xxx.xxx/cam/realmonitor?channel=1&subtype=0"

If you’re running an old gstreamer version, I don’t remember what was the actual issue, but something in plugins-ugly was leading to authentication failure. Uninstalling plugins-ugly was a workaround for such case.
