For those who haven't tried it, you can mount the output of OBS as a camera, which can be used as input for something like Zoom. So you can add graphics, multiple angles, switch between different views, etc...
This can also be used as a workaround for Teams on Linux not being able to get video input from a laptop's built in webcam.
Also, a bit off topic but has anyone had any luck getting the Windows version of Teams running in Wine? The Linux version is missing a few features I would really like to have (together mode, camera support, being able to view more than 4 participants at a time).
Re: video input - does the same problem occur when using the (unofficial, in maintenance-only mode) teams-for-linux[1] client?
(I haven't tried using the Windows version under Wine, sorry)
