IRL Docker Image

Provides tools and services for IRL streaming with OBS Studio as Docker Container.

Prerequisites

You will need:

• OBS Studio
• OBS Websocket
• VLC
• git
• Docker
• Live U Solo

RTMP Endpoint

• Port 1935

Webserver

• Port 80

docker-compose.yml

It is strongly advised to make use of docker-compose to build the image and run the container. Please create a docker-compose.override.yml to adjust the required settings to your needs. Use your full RTMP target URL as STREAMKEY. It's recommended to include a secret in your URL, e.g. rtmp://yourserver.invalid:1935/live?key=<YOURSECRET>

You can find an example in: ./examples/docker-compose/docker-compose.override.example.yml

Container Handling

Clone the repo

Use powershell, cmd or an WSL2 instance and go to the desired location on your local machine (e.g. c:\users\IRL\) using cd. Then execute the following command:

git clone https://gitlab.com/gpvkt/twitch-irl-docker.git

This process must be done only once. The repo content will be cloned into the subdirectory called docker.

Start container (first time run)

Use the powershell or cmd to go to your repo directory on your local machine (e.g. c:\users\IRL\docker\) using cd. Remember to create your docker-compose.override.yml. Then simply run the following command to start the Container, if needed docker-compose will start the build process.

docker-compose up

If the container starts successfully you should see something like (followed by more or less verbose status messages depending on your log level):

rtmp_1  | fcgiwrap                         STARTING
rtmp_1  | ircbot                           STARTING
rtmp_1  | liveucollector                   STARTING
rtmp_1  | nginx                            STARTING
rtmp_1  | obsctl                           STARTING
rtmp_1  | php                              STARTING
rtmp_1  | rtmpcollector                    STARTING

Update image

To update your Docker image run the following commands inside your repo directory (e.g. c:\users\IRL\docker\):

git pull
docker-compose build
docker-compose up -d

Troubleshooting

If something works wrong you can examine the status of your container by running docker-compose logs. To get even more informations you can switch inside your running container by executing docker-compose exec rtmp /bin/zsh. Once you're inside the container you can examine the logfiles of all processes using the following commands:

cat /var/log/supervisor/nginx.log
cat /var/log/supervisor/irl.log

To see the status of the processes or to restart them you can use the following commands:

supervisorctl status

supervisorctl restart nginx
supervisorctl restart php
supervisorctl restart fcgiwrap
supervisorctl restart obsctl
supervisorctl restart rtmpcollector
supervisorctl restart liveucollector
supervisorctl restart ircbot

If your docker image doesn't not reflect the expected changes after pulling an repo update run the following commands inside your repo directory:

git pull origin master
docker-compose kill
docker-compose rm --force
docker-compose build
docker-compose up -d

OBS Studio

After installation OBS Studio you need to add the obs-websocket plugin. We recommend using the 64 bit versions. You don't need to expose the websocket port to the internet, but choose a strong password anyway.

IMPORTANT: There are two version of obs-websocket, you will need the 4.x.x-compat version. We will update to 5.x.x in a future version of this project.

Also you need to add the required scenes in OBS, you will find an importable example in ./examples/obs/IRL.json. Please note that the example uses an VLC source for RTMP, so you need to have VLC installed. If you use OBS 64 bit you will need to use VLC 64 bit as well.

IMPORTANT: The Names of Scene-, Filter-, Audiosources etc. will be used as IDs in the OBS Web Remote App, therefore they MUST NOT contain any spaces and special Characters (like "'|/\^<>?*#'&%$()[]{}§!,.).

Please note that LiveU uses /live/live as default RTMP endpoint.

OBS Web Remote

An webbased OBS Remote Interface is included. You can reach it via http://localhost/remote.py. The Interface is password protected. The username is admin, the password is identical to your OBS_PASSWORD you set in docker-compose.override.yml.

Router/Firewall

You need to expose the RTMP Port (e.g. 1935) and the webserver port (e.g. 80) to the internet. Please configure your router and/or firewall accordingly. We also recommend to use an fixed IP Address for your Server, if you don't have one use an DynDNS service to get an domain name that always matches your current IP.

TTS

You can integrate the Simple TTS Bot into OBS Web Remote. Simply follow the installation process included in the bots README.md but use localhost as http_bind and 3000 as http_port.

Then add the following config to your docker-compose.override.yml:

# Integrate external TTS-Bot (see https://gitlab.com/gpvkt/twitchtts/)
- TTS=True
