This example demonstrates how Pion WebRTC can use an already listening UDP socket. On startup we listen on UDP Socket 8000.
We wrap this socket in a sharedUDPConn, this sharedUDPConn drops ReadFrom that don't appear to be WebRTC traffic.
go install github.com/sean-der/pion-webrtc-shared-socket@latest~/go/bin/pion-webrtc-shared-socket- Open
http://localhost:8080
In the command line you should see
2021/10/26 14:42:29 Open http://localhost:8080 to access
Peer Connection State has changed: connected
This means that the PeerConnection has started and connected succesfully. Now attempt to send non-WebRTC traffic to the process.
echo 'Testing' | nc -q 1 -u localhost 800
This will be printed in the terminal like so
Dropped packet that doesn't appear to be WebRTC: Testing
