SUMMARY After the update kamoso isn't working anymore. It opens with just a black background. The webcam is working fine in web browsers and telegram-desktop video calls. If I run kamoso with sudo it does use the webcam. If I run kamoso from terminal it gives this output: https://pastebin.com/pvYqrziZ STEPS TO REPRODUCE 1. open a terminal 2. execute "kamoso" OBSERVED RESULT Output errors; kamoso start but it won't use the webcam EXPECTED RESULT kamoso start and use the webcam to take pictures SOFTWARE/OS VERSIONS Linux/KDE Plasma: Manjaro 20.1, kernel 5.8.6 (available in About System) KDE Plasma Version: 5.19.5 KDE Frameworks Version: 5.73.0 Qt Version: 5.15.0 ADDITIONAL INFORMATION
I suggest to revert to Kamoso 20.04 for temporary solution

I use EndeavourOS which is another arch distro and kamoso 20.04 is the one work for me.

Actually on my system kamoso 20.04 did work before a complete upgrade. It worked again when I downgraded all the system, but not when downgrade only kamoso. I just did a test in live usb with latest kamoso version and it does work, even giving same warnings about deprecated QML. So probably it's a bug that happens after multiple upgrades on the same system, or maybe just my problem if nobody else can reproduce the bug
I tracked the issue up until here: https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/294 Only seems to happen with some webcams, hence some of us not noticing. I could reproduce it with droidcam.

Thank you to make me notice, unfortunately I can't understand those logs in the other thread but now I'm sure it's about some webcam as you said. I made a last attempt in live USB. Kamoso worked only once after I installed it. So the first time you run it, it works, and then it doesn't anymore. I hope this info can be useful to understand why this behaviour with some webcam.
UPDATE: SOLVED I opened Kamoso after some time, and after some upgrades. I'm always in Manjaro stable-branch. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Manjaro 20.1.1, kernel 5.8.11 (available in About System) KDE Plasma Version: 5.19.5 KDE Frameworks Version: 5.74.0 Qt Version: 5.15.1 The only changes in version appear to be KDE Frameworks and Qt Version. Plasma version is still the same version when the bug occurred. Kamoso is working normally now.
