For years I thought that online video conferencing and/or meetings would not be possible on FreeBSD. One of the first things I done on each of my laptops was to disable Camera and Microphone (along with Bluetooth) to save some battery time. While the Microphone would probably work I did not even tried to use it – did not had such needs to record anything with my laptop.
As time passed by I thought that maybe I will try what is the state of using Camera on FreeBSD and also how it is doing in the video conferencing/meetings space.
I was really astonished by the results … at least on my ThinkPad W520.
You may want to check other articles in the FreeBSD Desktop series on the FreeBSD Desktop – Global Page where you will find links to all episodes of the series along with table of contents for each episode’s contents.
I enabled Camera and Microphone in the BIOS (leaving Bluetooth disabled) and booted up my FreeBSD 13.0 as usual.
I then installed needed packages which are:
We will also need to load cuse.ko kernel module at each boot. We will use /etc/rc.conf for that.
# pkg install v4l-utils v4l_compat webcamd pwcview
# vi /etc/rc.conf
kld_list="${kld_list} cuse"
:wq
My Camera is listed at the end of the usbconfig(8) command.

We also need to add ourselves to the webcamd group.

We will now use pwcview(1) to check how the Camera works.

You can start pwcview(1) with larger resolution when needed.
Camera at mine ThinkPad W520 tops at 1280×720 resolution (HD) and 30 fps for refresh rate.

You may also try multimedia/cheese which has more ‘desktop’ interface when plain and simple pwcview(1) tool.
# pkg install multimedia/cheese

You may also test your camera online – https://www.onlinemictest.com/webcam-test/ – for example here.
You may test your microphone with audio/audacity or multimedia/ffmpeg(1)for example.
You as well use the – https://www.onlinemictest.com/ – online test for your mic.
You can also use audio/sox to record your sound in the terminal.
# pkg install sox celluloid
% pkg which -o $( which rec )
/usr/local/bin/rec was installed by package audio/sox
% rec test.wav

Aborted.
% celluloid test.wav
You hear your recording for example in the celluloid(1) player.
After I successfully tested the Camera on my ThinkPad W520 I then moved to Microphone testing … to just find out that my microphone is totally deaf. I could not record any sound with audacity(1) or ffmpeg(1).
At the beginning I first suspected it was a FreeBSD problem … unjustifiably fortunately.
Switching Microphone to [Enabled] in the ThinkPad W520 BIOS requires special procedure as shown on the BIOS screenshot below
1. Set the Microphone to [Enabled].
2. Select Save and Exit option in BIOS.
3. Power off laptop.
4. Disconnect AC power for at least 10 seconds (battery can be attached).
5. Power on laptop.
6. Boot FreeBSD as usual and now recording on Microphone works like a charm
Why so strange enabling procedure? Some people suggested that it needs to be that complicated to make sure that any third party will not enable your Microphone without your knowledge. Security concerns. Makes sense.
I was able to successfully start/join Google Meet and Zoom and also Teams meetings with this setup.
Sometimes it just required to use www/chromium instead of my default www/firefox browser.
Here is the detailed list of what works where.
Hope that will helps some of you to use join your meetings on FreeBSD system.
