Getting Started

To accomplish this mission you'll need to install the WSL (Windows Subsystem for Linux). I will not be covering the install process here, it is well documented by Microsoft, and is really a matter of running basically 3 commands.

note for WSL version 2 (recommended) you must install the GNU/Linux kernel component.

Installing a GNU/Linux image

Pull an image from the Windows store, in my case I used the latest ubuntu sadly centos wasn't an option.

Windows Store Install Ubuntu

Upon installation you will be asked to define a user, and set a password for that user. It is important to note that the user and password defined here are NOT the Windows user you're currently logged in with.

Getting Started

Start the WSL, this can be done by double clicking the icon for the GNU/Linux image you installed from the Start menu, or by running a Powershell or CMD session.

You can bring up the run dialog box by pressing <SUPER>-R, once open you can type "cmd" in the text box, then press "OK".
Windows run command: cmd

Now that the windows command prompt is running, type the command bash. This command will drop you into the GNU/Linux shell.

WSL login using bash

Once you're in the GNU/Linux shell, run the following commands (assuming you've installed the ubuntu image as I have).

sudo apt update
sudo apt install libnginx-mod-rtmp nginx-full stunnel4


Setting up NGINX is easy. Once installed (which was done in the previous command), simply edit the /etc/nginx/nginx.conf file and add the following config to the file. Editing the /etc/nginx/nginx.conf can be done in a lot of ways, built in methods include the use of vi and nano.

rtmp_auto_push on;
rtmp_auto_push_reconnect 2s;
rtmp_socket_dir /var/sock;
rtmp {

        server {
                allow publish;
                deny publish all;
                allow play;
                deny play all;

                listen 1935;
                chunk_size 4096;

                application facebook {
                        live on;
                        record off;
                        meta copy;
                        push rtmp://{facebook_stream_key};

                application youtube {
                        live on;
                        record off;
                        meta copy;
                        push rtmp://{youtube_stream_key};

                application alllive {
                        live on;
                        record off;
                        meta copy;
                        push rtmp://{youtube_stream_key};
                        push rtmp://{facebook_stream_key};
To use this configuration file you will need to be sure to update the options {facebook_stream_key} and {youtube_stream_key} to match your particular values.

With the core nginx.conf file edited, test the configuration to ensure its syntactically correct. To test, run the command sudo nginx -t. This command will quick inform you if there are any errors.

Error free nginx configuration

Setup stunnel

In order to stream to facebook live you will need stunnel to provide a secure interface. Sadly, at the time of this writing, the rtmp module provided by NGINX doesn't support rtmps which is the "secure" version of rtmp. There is an open issue for this missing feature, which can been followed here. Until this feature is implemented, we'll rescue our mission with a little stunnel.

At this point stunnel has already been installed, so all that's needed is a simple configuration file, which needs to be created at /etc/stunnel/stunnel.conf. Just as before, the file can be edited using whatever editor you chose, common editors are vi and nano.

Add the following section and options to the file.

client = yes
accept =
connect =
verifyChain = no


To start nginx and stunnel simply execute the following commands.

sudo stunnel4  #  Yes the command is "stunnel4"
sudo nginx

If there are no issues starting these applications, there will be no output.

Startup command, with no errors

Auto-Start the proxy service from the Desktop

To auto start NGINX and stunnel use a simple batch file which can be easily executed from the desktop, or added to the default startup folder.

To create a batch file open a simple editor like notepad.

The simple editor notepad can be easily opened by once again pressing <SUPER>-R and typing "notepad" in the text box, then press "OK".
Windows run command: notepad

With notepad open enter the following text and save the file.

bash -c "sudo killall stunnel4; sudo stunnel4; sudo killall nginx; sudo nginx"
When saving the file make sure the file name has .bat at the end of it, in my case the file name is startstream.bat.
You will also need to make sure that the Save as type is set to "All files". If this is not set correctly the file will save as a text document and windows will refuse to execute it.
notepad save batch file

I saved the file to my desktop, which makes finding, and quickly executing it, simple.

When this batch file is executed it will prompt you for a password, this will be the password that you setup when you installed the GNU/Linux image.
Batch file execution

Setup OBS

In the Stream section, set the Service option to custom, set Server option to rtmp://localhost:1935/alllive, and leave the Stream Key blank.

OBS streaming configuration

Click Apply, and you're done.

Celebrate, you're done

Now when you "Start Streaming" you'll be multi-streaming to youtube and facebook, you'll be doing it all from your one streaming machine, there will be little to no extra overhead, and it's FREE.

A couple of other features to talk about
  • When streaming using the Server URL rtmp:// the OBS stream will be pushed all configured destinations.
  • If you want to stream ONLY to facebook you can change the Server URL to rtmp://
  • If you want to stream ONLY to youtube you can change the Server URL to rtmp://
  • Additional applications can be setup in the rtmp section of your nignx.conf.

That's all folks

I hope you liked this simple post. If you use it, hit me up on twitter and let me know how it's working. Otherwise happy streaming and TTFN.
