Please help - I've been successfully using OBS Studio with Zoom for several months now. I use v4l2loopback to create a virtual camera and use the output as my zoom source and it worked great. Unfortunately, this week when I tried to host a Zoom meeting this way it didn't work. The virtual camera doesn't show up as an option in Zoom and to make matters worse, zoom even refuses to display any of the listed physical cameras. I did some testing and found that if OBS studio is running, even without a virtual camera output started, Zoom won't allow selection of any cameras. When I run Zoom alone, it works fine. My system specs are:
Linux Mint - kernel 5.4.0-53 (also tested with 5.4.0-52)
OBS Studio 25.0.3-dfsg1-2 (64 bit)
Zoom client 5.4.53391.1108 (also tested with prior version - not sure the ID)
Ironically, I found the same behavior on an older Linux machine that has not recently been updated and on a Windows 10 machine.
