I used the following command.

The error means that /dev/video0 is not a video capture device. Perhaps you need to set another device using:
gst-launch-1.0 v4l2src device="/dev/videoX" ! video/x-raw,width=640,height=480 ! x264enc ! h264parse ! rtph264pay ! udpsink host=127.0.0.1 port=5000
Where 'X' is the number of your video capture device. It might also happen that your device can't capture in 640x480 so you might want to add a videoscale before the caps and also it is safe to have a videoconvert before the encoder in case the input is in a format that the encoder can't handle.
So something like:
gst-launch-1.0 v4l2src device=<device> ! videoscale ! video/x-raw,width=640,height=480 ! videoconvert ! x264enc ! h264parse ! rtph264pay ! udpsink host=127.0.0.1 port=5000
