Installing uv4l on Raspian Buster

This is a recipe to install uv4l on a Raspberry 4 computer with Raspian Buster. Not much has changed since Raspian Stretch. As this recipe is followed, please pay attention to the details!

After this install, run uv4l as follows:

uv4l --driver raspicam --auto-video_nr --encoding h264 --enable-server on

And then view the stream in a browser with (pleae note your IP address might be different)

http://192.168.1.9:8080/stream

Please see my video controller software PiE, it uses uv4l out of the box on both Stretch and Buster.

Recipe

(1)

Add the uv4l key to your apt-key package manager.

curl http://www.linux-projects.org/listing/uv4l_repo/lpkey.asc | sudo apt-key add -

Note: I am not sure what the difference is between lpkey.asc and lrkey.asc? My installations on Stretch were using the wrong key! I was using lrkey.asc while I should have been using the p variant lpkey.asc. Not sure why this worked on Stretch but it did. For Buster, you must use lpkey.asc.

(2) Add the following line to /etc/apt/sources.list using sudo pico /etc/apt/sources.list

deb http://www.linux-projects.org/listing/uv4l_repo/raspbian/stretch stretch main

(3) Update apt-get and install with apt-get using

sudo apt-get update
sudo apt-get install uv4l uv4l-server uv4l-raspicam

Important: I was previously using sudo apt-get -qq --allow-unauthenticated install uv4l uv4l-server uv4l-raspicam and with Buster, the use of --allow-unauthenticated seems to break the install?

(4) Run the uv4l server with

uv4l --driver raspicam --auto-video_nr --encoding h264 --width 1280 --height 720 --enable-server on

And then view the stream in a browser with (please note your IP address might be different)

http://192.168.1.9:8080/stream

Troubleshooting

Sometimes you get multiple /dev/video0, /dev/video1, /dev/video10 excetera devices. Feel free to remove them with sudo rm /dev/video* and then maybe restart with sudo reboot.
