Thanks to corona, it's prime time for pranking co-workers. I would love to get this working :D

Seriously, my mail is active 24/7 receiving new reports, because people have a lot of time now 😆
Hopefully some people have enough time send me PRs too 🙏

Any news on this? I'm running 5.5.7-1 Manjaro and no devices in /dev are created either. My log looks similar, though not as verbose.

It says akvcam is in use, but doesn't list what it's being used by. Running rmmod -f akvcam outputs:

rmmod: ERROR: could not remove 'akvcam': Resource temporarily unavailable
rmmod: ERROR: could not remove module akvcam: Resource temporarily unavailable

from akvcam.

@viking maybe some program is using the module, this could help.

I will make a new release later.

viking commented on September 21, 2024

Thanks, you're right. It looks like a service on my machine monitors the creation of /dev nodes and starts using the newly created /dev/videoX node that akvcam creates.

Issue fixed in 1.0.3, closing.
