Worked out of the box for me (Mint Cinnamon 20.04, NVidia drivers and KDE installed, Logitech WebCam). Haven't tried it in a video call yet but it detected my webcam and monitors instantly and I tried out a few plugins (the ASCII and Matrix ones are particularly good, by the way!)
I'm not sure what the issue was with it not launching in some versions but it worked right "out of the box" for me through the Software Manager. So far on Mint Linux/Ubuntu this is the easiest program for getting into webcam presentation with special effects. No issues and seems verbose enough for general uses. Tested on Mint LInux 20 (upgraded from 19) on a Lenovo T480 using an external Logitech Brio webcam.
Probably a good application but doesn't launch.
does not launch. Have to kill process. downloading the version from their site works great, just not the software manager version
But... v.1.0 (from https://webcamoid.github.io/ on: Linux Mint 18.3 Cinnamon 64b) works perfectly.
Mint 18.3 Cinnamon - Will not launch
