To install Docker, you need to add Docker's official GPG key and set up the Docker stable repository.
install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/debian/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
chmod a+r /etc/apt/keyrings/docker.gpg
echo "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian \
"$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null
apt-get update
apt update --allow-insecure-repositories
apt --allow-unauthenticated install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
Create a configuration file for the RTMP server (rtmp.conf
) and a script to run the Docker container (run.sh
).

First, you need to install FFmpeg and Docker. FFmpeg is a tool that can capture your desktop and stream it to an RTMP server. Docker is used to run the RTMP server in a container.
sudo apt update
sudo apt install ffmpeg
sudo apt install ca-certificates curl gnupg lsb-release
Before you start streaming, you need to find out your screen resolution. You can do this with the xdpyinfo
command.
xdpyinfo | grep dimensions
Then, you can use FFmpeg to capture your desktop and stream it to the RTMP server. Replace 1366x768
with your actual screen resolution, and replace rtmps://163.5.182.40:1935/rtmp
with your actual RTMP server URL.
ffmpeg -f x11grab -s 1366x768 -framerate 5 -i :0.0 -f flv rtmp://163.5.182.40:1935/live
That's it! You're now streaming your desktop to multiple servers simultaneously.
