How to stream only audio/video from mpeg file using gstreamer?

I am new for gstreamer. I want to stream only audio/video on a rtp port. I
tried following command to stream only video from mpeg file :
$ gst-launch-1.0 -v rtpbin name=rtpbin filesrc location=KRSNA.mpg !
decodebin ! 'video/mpeg' ! rtpmpvpay ! udpsink host=127.0.0.1
port=9078
Following is the verbose for command :
