Thank you for this information, I was unaware of this parameter.

I just tried it, unfortunately without success.  Here follows what I
did for the record:
- set both kern.audio.record and kern.video.record to 1
- have the rights to /dev/video0 properly set in /etc/fbtab
- added '/dev/video0 rw' in /etc/chromium/unveil.main and
  /etc/chromium/unveil.utility_video as advised in the FAQ
- used this command line to launch chromium:
  chrome --incognito --user-data-dir=/tmp/chrome 
--enable-features=RunVideoCaptureServiceInBrowserProcess

But chromium still can't access the webcam and /var/log/messages still
prints:

uvideo0: could not SET probe request: STALLED

as soon as I tick the "allow chromium to use your webcam" box.

I used https://webcamtests.com to do the test.  Iridium/Chromium both
fail while firefox-esr succeeds.
