Microsoft teams is showing a black screen instead of the video of my camera. I use a sony a5100 camera that is connected using an Elgato Cam Link 4 on a computer that is running Ubuntu 18.04.5 LTS. If I use the browser version of teams instead of the app, I do get a working video but I can only see one other participant in my conference calls. I tried several solutions (using OBS studio, reducing bit rate of camera by lowering settings) but none of these work. The video works fine for other apps (like Zoom) and also works in teams when running windows 10. Is there a solution to this problem that works on Ubuntu?

    Hi,

    I have the same issue. The reason is that there is a max. resolution limitation for some devices. My Logitech webcam can run on fullhd but Cam Link is limited to 720p. With higher resolution, you get a black screen.
