Connect Jetson Nano to a laptop camera via RTP

Hello,

Yes, I run Linux on the laptop. I followed the steps on Jetson Nano FAQ and when I run:

$ ./test-launch “videotestsrc ! x264enc ! h264parse ! rtph264pay name=pay0 pt=96”

it outputs stream ready at rtsp://127.0.0.1:8554/test

Then on my Jetson:

$ gst-launch-1.0 uridecodebin uri=‘rtsp://<IP_HOST>:8554/test’ ! nvoverlaysink

I get:

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Progress: (open) Opening Stream

What am I doing wrong?

Note: IP_HOST is my laptop IP.
