How can I HTTP stream a USB webcam plugged into my headless Ubuntu Server remotely?

I have a USB webcam plugged into my computer running Ubuntu Server at home. I want to access its video feed remotely.

I am connected to the server's network with a VPN, so I can SSH into it using something like ssh name@192.168.0.10, and can run commands this way.

I have tried many commands.

cvlc -I dummy -vvv v4l2:///dev/video0 will display the video feed in ascii in the terminal, so this tells us the webcam works.

How can I stream the results in HTTP for viewing in my browser when I am not at home?

Using https://motion-project.github.io, I could create a simple config file, and do a standard reverse proxy using NGINX.

Here is my motion.conf file:

stream_quality 98
stream_maxrate 6
stream_port 1984     <------ required
stream_localhost off <------ required
output_pictures off
framerate 30
ffmpeg_video_codec mpeg
width 640
height 480
auto_brightness off
contrast 0
saturation 0

Here is my NGINX server

server {
    server_name DOMAIN;
    root /var/www/html;

    auth_basic "Admin"; # password protected domain
    auth_basic_user_file /etc/apache2/.htpasswd;

    location / {
        proxy_pass http://127.0.0.1:1984/;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Prefix /;
    }
