1 webrtcbin plugin in jetson nano does not work for missing dependence nicesrc/nicesink and GstWebRTC-1.0.typelib,
the patch direction just fixed this problems.

2 modified https://github.com/centricular/gstwebrtc-demos.git , the demo needs to start browsers first and then start jeston-client,
just add client-list-push to auto connect

3 modified the webrtc client, to use jetson_nano hw-acceled pipline and hardware

start_the_server:
cd server &&  python3 simple-server.py


start_the_client:
cd client && python3 jetson_webrtc.py --server=wss://127.0.0.1:8443 -1


start the browser:
https://xxx.xxx.xx.xxx



faq:
1 pipeline start failed 
I use the csi camera and usb-microphone, to replace it with your environment . reference  "docs/Accelerated_GStreamer_User_Guide.pdf "
