How to decode multiple rtsp stream with gstreamer on jetson tx2

Hello,everyone:
I decoded rtsp stream from IP camera with gstreamer-1.0,it works OK.

Command:
gst-launch-1.0 -e rtspsrc location=rtsp://admin:12345678@192.168.1.2/h264/ch1/main/av_stream latency=0 ! rtph264depay ! h264parse ! omxh264dec ! queue ! nveglglessink sync=false

But now there are two rtsp stream,How can I decode them and display?
