Running mediamtx with WebRTC when offline

[qeroll]

Question

Hi,

I would like to run mediamtx on my laptop, an Ubuntu 20.04 laptop, in order to serve a WebRTC stream from an RTSP stream.
Can I use mediamtx even if my computer is offline / no even connected to a Network Cable or WiFi?
If so, can I use it on my LAN even if my LAN has no internet connection, so that other computers on the same LAN can view streams from each other?

Hello,

Can I use mediamtx even if my computer is offline / no even connected to a Network Cable or WiFi?

Absolutely yes since #2686 removed the need for an external STUN server, which required internet access. The WebRTC implementation bundled inside MediaMTX can be used in offline networks.

Hey,
I'm using the simplest yml i can and i tried using mediamtx webrtc offline (on my laptop, disconnected ethernet and disabled wifi)
I'm using mediamtx v1.3.1 on MacBook Air M2 (OS Version 14.5 (23F79))
here is my yml:

logLevel: debug
metrics: true
webrtcAdditionalHosts: [192.168.x.x, localhost, 127.0.0.1, 0.0.0.0]
webrtcLocalTCPAddress: :8189
webrtcLocalUDPAddress: :8190
paths:
  webcam:
    source: rtsp://127.0.0.1:8556/webcam

Is there another configuration i need to use?
