It works using chromium not the Zoom app (which only runs on x86, not ARM). I tested it with a two-person, two-video stream call. You need a screen (I happened to have a spare 7″ touchscreen). You also need a keyboard for the initial setup, and a mouse if you don’t have a touchscreen.
The really nice thing is that Video4Linux (bcm2835-v4l2) support has improved so it works with both v1 and v2 raspi cameras, and no need for options bcm2835-v4l2 gst_v4l2src_is_broken=1 🎉🎉
- Install Raspian Buster
- Connect the screen keyboard, mouse, camera and speaker/mic. I used a Sennheiser usb speaker / mic, and a standard 2.1 Raspberry pi camera.
- Boot up. I had to add lcd_rotate=2 in /boot/config.txt for my screen to rotate it 180 degrees.
- Don’t forget to enable the camera in raspi-config
- Enable bcm2835-v4l2 – add it to sudo nano /etc/modules
- I increased swapsize using sudo nano /etc/dphys-swapfile -> CONF_SWAPSIZE=2000 -> sudo /etc/init.d/dphys-swapfile restart
- I increased GPU memory using sudo nano /boot/config.txt -> gpu_mem=512
You’ll need to set up Zoom and pass capchas using the keyboard and mouse. Once you have logged into Zoom you can often ssh in and start it remotely like this:
export DISPLAY=:0.0 /usr/bin/chromium-browser --kiosk --disable-infobars --disable-session-crashed-bubble --no-first-run https://zoom.us/wc/XXXXXXXXXX/join/
Note the url format – this is what you get when you click “join from my browser”. If you use the standard Zoom url you’ll need to click this url yourself, ignoring the Open xdg-open prompts.
You’ll still need to select the audio and start the video, including allowing it in the browser. You might need to select the correct audio and video, but I didn’t need to.
I experimented a bit with an ancient logitech webcam-speaker-mic and the speaker-mic part worked and video started but stalled – which made me think that a better / more recent webcam might just work.
