Stream to VRChat

A set of files to create a server that can stream your desktop to VRChat video players with low latency.

Setup

This guide works for Windows with your home internet connection, which is totally free. However, your home internet connection needs to be sufficiently fast, and you need to know how to configure your router to forward a port to your PC.

Alternatively, if your home internet connection isn't fast enough or you just want it always available, there's a rough guide on how to set up a Virtual Private Server (VPS) with Linux, which come for as low as $4/month.

Windows (Local PC, Home internet connection)

Prerequisites

• MediaMTX Standalone (Scroll down to "Assets" and then pick the file "mediamtx_vX.X.X_windows_amd64.zip")
• Port forward port 8554 (TCP) from your home router to your PC
• Your home IP address (find out by googling "what is my IP")
• Sufficient upload speed with your home internet connection

Starting

• Unzip the downloaded Zip file to a new directory, it should contain the file "mediamtx.exe".
• Copy the file mediamtx.yml into the same directory.
• Double click "mediamtx.exe"
• If a red warning screen pops up (Smart Screen), click "Run Anyway"

Linux (On VPS, paid)

Prerequisites

• Knowledge of how to connect to a Linux server with SSH
• Knowledge of how to edit a file in a Linux terminal
• Docker
• Your own VPS or machine where ports 443, 1936 and 8554 are available via IPv4 I recommend Hetzner for the most bang for your buck, but any other VPS hosting provider will do as well, like DigitalOcean, OVH or Vultr
• A DNS name for your server IP. If you have your own domain name, great! If not, you can get one for free at FreeDNS.

On a fresh Ubuntu 22.04 system, run this:

# Install Docker packages
sudo apt install docker.io docker-compose
# Clone this repository with Git
git clone https://github.com/MorghusDragon/stream-to-vrchat.git
cd stream-to-vrchat
# (Optional) Enable Firewall for security
ufw allow OpenSSH
ufw allow 443/tcp
ufw allow 1936/tcp
ufw allow 8554/tcp
ufw enable

Starting

• Use git clone or download the Zip file of this repository and unzip it into a new directory
• Edit the .env file and set the HOSTNAME and ACME_EMAIL variables
• (Optional) Edit the mediamtx.yml file and change the publishUser and publishPass values for added security
• Run docker-compose up -d to start the service

Streaming

Using OBS, change your Stream Service to "Custom" and enter the following URL:

• Windows from your PC:

  rtmp://localhost/
  

• Linux with VPS:

  rtmps://your-dns-name.com:1936/
  

Replace your-dns-name.com with the HOSTNAME you set in your .env file.

Set your Stream Key to stream. If you set a username and password in your mediamtx.yml file, change the Stream Key to stream?user=myusername&pass=mypassword.

That's it! Now you can click "Start Stream" in OBS.

In VRChat

Go to any video player in VRChat and enter the following stream URL:

• Windows from your PC:

  rtspt://your-home-ip:8554/stream
  

  You can find your home IP by googling "what is my IP".

• Linux with VPS:

  rtspt://your-dns-name.com:8554/stream
  

If it doesn't work on first try, try once more or click the Sync button.
