publish stream from Smartphone (flutter-app) to Server, and forward udp-Multicast

[sandmen]

Hi,
I have read the documentation, but maybe I have overseen some thing.
My use case, smartphone should publish a stream to a server, where rtsp-simple-server is running.
Smartphone has LTE, and server is accessible from internet.
Now, i want to forward this stream to several devices (smartphone,Laptop....) I think, 10-20 users.

Is that a use case for rtsp-simple server ?
Any example configs for that ?

Thanks, for your feedback.

Hello, this is supported with the standard configuration. You may need to disable the UDP protocol, which is not fit for the internet:

protocols: [tcp]

You can then publish to

rtsp://server-ip:8554/stream

and read the stream with RTSP, RTMP, HLS or WebRTC from any device.

Keep in mind that 4G/LTE some provider will only allow ports 80/443 traffic outgoing in some country's and incoming ports will be likely blocked under CGNAT however there is few Mobile ISPs that will give you a Public IP facing for incoming connections.

RTMP Camera for Android.

and then with this app you can do what @aler9 has suggested above.
