I use Chromacam (
https://www.chromacam.me/ ) to change the background in videoconferencing apps, like Zoom, MS Teams and BBB. In these apps I can choose which camera I want to use: the integrated webcam of my laptop (the 'normal' camera with normal background) or 'Chromacam' with a background that gives more privacy.
This works fine in Zoom and MS Teams. But in BigBlueButton I encounter problems. If I choose the 'integrated webcam' in BBB (so, not Chromacam; not a virtual background) while chromacam still is installed, the integrated webcam gives an error and doesn't function.
After de-installing chromacam I could choose the integrated webcam again and this also worked.
Like said, installing chromacam next to my integrated webcam doesn't cause problems in e.g. Zoom.
--> @BigBleButton developers: can you look into this? Maybe there is a bug in BBB?
