srt-relay

Relay server for SRT streams between two endpoints.

Usage

Setup the server

Install Docker

You have to install Docker and Docker Compose to run the server.

Start

git clone https://github.com/TechnoTUT/srt-relay.git
cd srt-live-server
echo "<your-passphrase>" > .passphrase
docker compose build
docker compose up

You must replace .passphrase with your own passphrase.

If you want to run the server in the background, you can use the -d option.

docker compose up -d

Firewall

If you are using a firewall, you have to open the port 2000/udp and 3000/udp. For example, this is how you can open the ports on firewalld.

firewall-cmd --zone=public --add-port=2000/udp --permanent
firewall-cmd --zone=public --add-port=3000/udp --permanent
firewall-cmd --reload

Stop

docker compose down

Stream to the server

You can use any SRT streaming software like OBS Studio to stream to the server.
Please configure the stream settings as follows:

• URL: srt://<server-ip>:2000?mode=caller&passphrase=<your-passphrase>&pbkeylen=32
• Stream key: None

Watch the stream

You can receive the stream from the server using any SRT compatible player like VLC or OBS Studio. Please configure the player settings as follows:

• URL: srt://<server-ip>:3000?mode=caller&passphrase=<your-passphrase>&pbkeylen=32
