Recently, I tried emulating a virtual webcam with the Linux kernel
v4l2loopback (also using OBS Studio v24, if that's important).
While trying to use the emulated webcam with Google Meets, however, the left and right sides were always cropped. I have tried a variety of different aspect ratios and resolutions, all to no avail. Such a desire is feasible, and has worked for me in the past (I lost a config file).
I would appreciate it if anyone had any ideas or advice as to how I could potentially test to see which aspect ratio Google Meet wants, or if anyone has already figured this out (and haven't lost it like me).
(If I find out I will add an update here.)
