How to stream a USB webcam from a raspberry pi over the network

I've struggled with this for a while, but I've finally found a good solution, which has low-latency and good image quality. I'm using a raspberry pi zero 2w with a USB camera.

Use ustreamer

ustreamer is a simple util that allows you to stream a video with very litte latency and a stable 30 fps even from the Pi Zero 2W.

sudo apt install ustreamer

# List all the available formats for your camera (replace video0 with what you need)
v4l2-ctl --device=/dev/video0 --list-formats-ext

# From this list, note if your camera supports MJPEG and select
# an available resoluzion and frame-rate

# Stream a MJPEG video from video0 at 30fps
# --host 0.0.0.0 exposes the stream on your local network
ustreamer -d /dev/video0 -m MJPEG -f 30 --encoder HW --host 0.0.0.0 --port 8080

Now visit with your browser or open with OBS: http://raspberrypi.local:8080/stream

Please note that softwares like OBS or VLC might add some buffering which would add delay
