I am getting a green flicker however and I have filed for this a new bug: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=245505 Hans Petter - I get the same green screen when launching the webcam for a first time with pwcview - the picture remains green until the webcam sends something. Where is this "green" thing coming from? Is it an empty webcam buffer? Is there any additional debugging in webcamd I can try? to sum up: - the green picture appears once in pwcview until the webcam appears to work, after this it works stable - the green picture never appears in firefox - green screen flashes accross the webcam picture whenever I use chromium Also: participants in the Zoom meeting cannot hear my audio at all (the audio device gets connected, and I can enable it in chromium). I have noticed few ioctl warnings and filed them under https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=245624 but maybe those are not related at all. Any ideas how to troubleshoot this? The mic works fine otherwise (also in firefox). --1563967779-385055074-1586946926=:49460 Content-Type: application/pkcs7-signature; name=smime.p7s Content-Transfer-Encoding: BASE64
