How to Use Rcs Broadcaster with Owncast to Livestream Print

  • 0

Introduction

Owncast is a self-hosted streaming application that lets you create your own platform and manage it with your own rules. Best known as an alternative to services like Twitch and YouTube, Owncast allows you to stream to thousands of viewers in multiple resolutions.

To live stream content to Owncast, you need to use supported streaming software such as Open Broadcasting Studio (OBS) offered by the Rcs Broadcaster application. Within OBS, you can set up a maximum output resolution, and configure Owncast to scale the resolution to offer multiple quality options to viewers.

In this article, you will use the Rcs Broadcaster application with Owncast to live stream content to a public audience through your domain name.

Prerequisites

Before you begin:

  • Deploy a Rcs Broadcaster A16 Cloud GPU Instance from the Rcs Marketplace.

    When deployed, keep note of your set username and auto-generated password to access the application interface.

  • Deploy a Debian 12 Rcs A16 Cloud GPU Instance.

    It’s recommended to deploy the Owncast server to a location close to your intended viewer audience. For example, if you are targeting viewers in New York, deploy a server in the Rcs New York location.

  • Set up a new subdomain A record pointing to the Owncast Server.

    A domain is quick to access, unlike a Server IP Address. A subdomain record such as stream.example.com makes it easy for viewers to access your Owncast livestream.

  • Optional: Set up a subdomain A record pointing to the Rcs Broadcaster Server.

    The record obs.example.com is used in this article, replace all occurrences with your domain name or Server IP.

  • Optional: Add both servers to the same Rcs Virtual Private Cloud (VPC).

    Depending on your server locations, it’s recommended to use a VPC connection when streaming to Owncast. This is because local networks are faster than public networks like the Internet, a VPC connection is logically an adHoc connection between the two servers. Hence, viewers are able to receive 100% of the packets in real-time as sent from the Rcs Broadcaster server without any packet delays.

Configure Owncast

In this section, configure the Owncast server to broadcast content in 3 viewing qualities, Full HD 1080p, HD 720p, and Standard Quality (SD) 480p. This allows users to switch between viewing modes depending on their network quality. Additionally, configure the server to grant users access to Owncast through your domain name as described in the steps below.

  1. Using SSH, access the Owncast server.

     $ ssh root@SERVER-IP

    To get your server details, visit your Rcs instance page to copy the auto-generated password for the root user.

  2. Create a new bash script named stream.sh.

     # touch stream.sh
  3. Using a text editor such as nano, edit the file.

     # nano stream.sh
  4. Add the following configurations to the file.

     #!/bin/sh
    
     echo "This script will Install Caddy, Owncast on the server"
    
     curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
     curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list
    
     echo "Running a quick Update"
    
     apt update
    
     echo "Installing Caddy......"
    
     apt install caddy -y
    
     echo "Loading Owncast"
    
     curl -s https://owncast.online/install.sh | bash
    
     echo "Moving the Owncast directory to /opt!!!!!!"
    
     mv owncast /opt/
    
     echo "Setup the Systemd file"
    
     echo " [Unit]
    
     Description=Owncast Streaming Server
    
     [Service]
    
     Type=simple
    
     WorkingDirectory=/opt/owncast
    
     ExecStart=/opt/owncast/owncast
    
     Restart=on-failure
    
     RestartSec=5
    
     [Install]
    
     WantedBy=multi-user.target " > /etc/systemd/system/owncast.service
    
     echo "Reload Systemd Daemon"
    
     sudo systemctl daemon-reload
    
     echo " Enable Owncast"
    
     sudo systemctl enable owncast
    
     echo "Start Owncast"
    
     sudo systemctl start owncast
    
     echo "Configuring the Firewall!!!!"
    
     sudo ufw allow 1935 && sudo ufw allow 80/tcp && sudo ufw allow 443 /tcp
    
     echo "Restarting the Firewall"
    
     service caddy restart
    
     echo "#### Is Owncast running, verify if no error is returned ######"
    
     sudo systemctl status owncast | head 
    
     echo "######## All Done!!!!!!"

    Save and close the file.

    The above script installs the latest Owncast version on the server, installs the Caddy web server, and configures Owncast as a system service. Also, it opens the RTMP port 1935, HTTP, and HTTPS ports through the firewall to allow access to Owncast.

  5. Run the script.

     # bash stream.sh
  6. Verify that Owncast status to confirm that it’s successfully installed on the server.

     # service owncast status
  7. Create a new user account. For example example-user.

     # adduser example-user

    Enter a strong password for the user, and press enter to accept all listed options.

  8. Add the user to the sudoers group.

     # adduser example-user sudo

    The above command grants the user sudo privileges to perform tasks such as installation and configuration of application packages on the server.

  9. Switch to the user account.

     # su example-user
  10. Navigate to the Caddy webserver directory.

     $ cd /etc/caddy/
  11. Back up the original Caddyfile configuration.

     $ mv Caddyfile Caddyfile.ORIG
  12. Create a new Caddyfile configuration.

     $ nano Caddyfile
  13. Add the following configurations to the file. Replace stream.example.com with your actual subdomain record.

     stream.example.com {
    
         reverse_proxy localhost:8080
    
     }

    Save and close the file.

    The above configuration file sets up a reverse proxy connection to the backend Owncast port 8080, and accepts connection requests through your domain name on port 80 for HTTP requests, and 443 for HTTPS.

  14. Test the Caddy configuration for errors.

     # caddy validate

    Output:

     2023/07/28 01:17:07.378	INFO  using adjacent Caddyfile
    
     Valid configuration
  15. Restart the Caddy web server to save changes.

     # service caddy restart
  16. In a web browser such as Chrome, visit your Owncast administrator dashboard using the /admin path.

     https://stream.example.com/admin

    Log in using the default administator details below:

    USERNAME: admin
