🌻:Services/Stream/Multicasting

In the spirit of POSSE, accessibility, and a general love of tinkering, when I started doing streaming I wanted to set things up to stream to peertube, youtube, twitch, and as many other places as I wanted. I had to setup three tools to do this, OBS, a plugin called obs-multi-rtmp, and a (optional but very, very useful and highly reccomended) server running nginx-rtmp

So the steps in a nutshell are:

1. Install/Build OBS: obsproject.com/wiki/install-instructions#linux
2. Add the multi-rtmp-plugin: github.com/sorayuki/obs-multi-rtmp
3. Optional: Setup Nginx to take some pressure off your streaming computer: github.com/arut/nginx-rtmp-module

Settings these tools up in a way that streamed to those three services was more of a project then I thought it would be (I setup ngnxrtmp first but a bug prevented it from multicasting to peertube, which is the place I wanted to stream to the most)

So for posterity here is a quick rundown of the process I used to stream to multiple places. Feel free to edit this if you find spelling errors or just generally hate it when somone copy pastes notes intented only for their personal use onto the internet without much additional editing

I am going to assume you are using a fresh uptaded and empty linux machine running either debian 10 or debian 11, since thats what these notes assume and I am just copy pasting right now till I clean up the notes.

cd
git clone github.com/sorayuki/obs-multi-rtmp.git
cd obs-multi-rtmp
nano ./ci/install_ubuntu.sh

edit file so it looks right. remove the weird ubuntu stuffs

make it so it looks like below:

---

#!/usr/bin/bash

set -eux

: "${OBS_INCLUDE_DIR:=/usr/include/obs}"
: "${OBS_API_SRC_URL:=raw.githubusercontent.com/obsproject/obs-studio/#OBS_VER#/UI/obs-frontend-api/obs-frontend-api.h}"

#sudo add-apt-repository -y ppa:obsproject/obs-studio
#sudo apt-get update
#sudo apt-get install -y mesa-common-dev obs-studio qtbase5-dev qtdeclarative5-dev

obs_ver=$(obs -V)
obs_ver=${obs_ver-/ }
obs_ver=($obs_ver)
obs_ver=${obs_ver[2]}

curl -fsSLo /tmp/obs-frontend-api.h "${OBS_API_SRC_URL#OBS_VER#/$obs_ver}"
sudo mkdir -p "$OBS_INCLUDE_DIR/UI/obs-frontend-api"
sudo mv /tmp/obs-frontend-api.h "$OBS_INCLUDE_DIR/UI/obs-frontend-api"

---

resume by running ubuntu scrip

./ci/install_ubuntu.sh
INSTALL=1 ./build_linux.sh

open obs test
