First of all, we need to do all the things indicated here: https://gist.github.com/DevStefIt/23b8971db7e3fe084d29f2c915fb7773
We need to modify the Nginx configuration file:

`sudo vim /etc/nginx/nginx.conf`

Then, have to add the following lines in the existing RTMP configuration (or create a new one if you do not have it)

```
. . .
rtmp {
        server {
...
                application live {
                        live on;
                        record off;
                        hls on;
                        hls_path /var/www/html/stream/hls;
                        hls_fragment 3;
                        hls_playlist_length 60;
                        hls_cleanup off;

                        dash on;
                        dash_path /var/www/html/stream/dash;
                        dash_cleanup off;
                }
        }
}
...
```

We need to configure a block in the `sites-available` folder.

`sudo vim /etc/nginx/sites-available/rtmp`

And insert the following lines:

```
...
server {
    listen 8088;

    location / {
        add_header Access-Control-Allow-Origin *;
        root /var/www/html/stream;
    }
}

types {
    application/dash+xml mpd;
}
```

Port `8088` is chosen because it is different than the other chose ports.

We enable port 8088 in TCP mode on the firewall

`sudo ufw allow 8088/tcp`

We create the folders of interest

```
sudo mkdir -p /var/www/html/stream/hls
sudo mkdir -p /var/www/html/stream/dash
```

We also grant a reasonable access for the current user

```
sudo chown -R $USER:$USER /var/www/html/stream
sudo chmod -R 775 /var/www/html/stream
```

We reload Nginx

`sudo systemctl reload nginx`
