I'm using version 48 (Flatpak). It is a simple camera app, it only does the basics, take photos, video and now (since v.48) it can scan QR codes. At first, it didn't work for me on LMDE 6. I found that it requires a more recent version of PipeWire than the 0.3.65 available in Linux Mint Debian 6. So, I updated PipeWire via Debian backports to version 1.2.7 and now it works fine!
Linux Mint Cinnamon 22.1. Does exactly what I need it for--a camera preview to make sure my webcam is working correctly in the rare case I want it for a virtual meeting or similar on my PC.
Linux Mint 21.3 with Elgato USB cam: "Could not play camera stream" while it works everywhere else. ¯\_(ツ)_/¯
Dittoing Maybe_Matty. I get a frozen loading spiral when I try and boot it. Running Linux Mint 21.3 Cinnamon.
