Thanks for the replay.
Your answer left me a bit confused.

Do you mean that I should not mux them and do something like:
gst-launch-1.0 v4l2src ! video/x-raw,width=640,height=480 ! timeoverlay !
tee name="local" ! queue ! autovideosink local. ! queue ! x264enc
tune=zerolatency byte-stream=true bitrate=500 threads=1 ! h264parse
config-interval=1 ! rtph264pay ! udpsink host=192.168.100.3 port= 5000
udpsrc port=5000 caps=\"application/x-rtp,payload=96,encoding-name=H264\" !
queue ! rtph264depay ! h264parse ! decodebin ! autovideosink
pipeline 2 :
gst-launch-1.0 pulsesrc ! audioconvert ! audioresample ! speexenc !
rtpspeexpay ! udpsink host=192.168.100.3 port=4444 udpsrc port=4444
caps="application/x-rtp, media=(string)audio, clock-rate=(int)16000,
encoding-name=(string)SPEEX, encoding-params=(string)1, payload=(int)110" !
rtpjitterbuffer ! rtpspeexdepay ! speexdec ! audioconvert ! audioresample !
And playing similar pipelines on other PC. I have tried this type of
approach and the video part was working but audio part was creating problem.
when I run the second pipeline there is no audio at either end while they
work fine independently. Can you please explain the reason. And me out of
