When I am having a video call with someone-- whether on Skype, Zoom, or Google Meet, everyone sees a mirror image of me.
I am on a MacBook Air (manufactured in 2015) on Mac OS Big Sur. I am using an external webcam, a Depstech 2K. I bought this webcam so that I wouldn't have to keep flipping up my laptop whenever I wanted to get on a video call (I just rest it on the external monitor). I went to Depstech's website and found nothing of use for troubleshooting this mirroring problem. I also contacted them and they said they had never received this complaint before. I searched the settings on my Mac and Googled the issue. Nothing. The only thing that alleviates this issue is using the 3rd party software, ManyCam. It works with Zoom but crashes when I try it with Skype (I haven't tried it with Google Meet yet).
Clearly, this is not an issue with any of the video software I'm using. Otherwise, I wouldn't have the problem across multiple video conferencing platforms. I didn't have this problem with my Mac's built-in webcam but, as I've said, I want to use an external one. And yet Depstech said they have never received this complaint before.
Does anybody have an idea of what the issue could be? I find it incredibly hard to believe that the only way to deal with this is to use workaround software like ManyCam.
