I'm a PCLinuxOS user & maintainer. The person who hosted the site, wiki, and forum lost his equipment to a fire. You can find the new forum here: https://www.pclinuxos.com/forum

The main PCLOS page just points to the new forum now, Tex put a temporary WordPress template there.

APT-RPM can definitely be used, but APT-RPM is quite old and unmaintained, similar to Xorg.

I would be happy to come to Devuan as someone who enjoys packaging. I used it for a while several years ago, but DEB packaging seems a lot more daunting than RPM. I asked here once how to package for it because I would be happy to help paint the way forward for Devuan but nobody replied and the only package I made which is my usual guinea pig for different packaging formats, zramen, just made me very skeptical of packaging in the DEB format.

No problem. Its not actually in Devuan repos as I'm not sure how to propose it. It may have to first be enabled by you if I remember correctly. I am currently on PCLOS, not Devuan.

I really like the Logitech Marble but I just recently bought a Porlei TM551 and its fantastic if you're right-handed. It comes with a scroll wheel which is notably missing from the Marble, but the Marble can be configured to have scrolling if you hold down the left back button and move the ball. Both are very comfortable to use.

EDIT: Just realized you also used the Marble and ran into similar problems as I did. Alos that you are left-handed. I haven't used any others besides the Marble that could be used left-handed, maybe the Kensington Orbit.

The problem is we don't have an AppStream repository like Debian does. AppStream is what holds all the fancy metadata showing the icons, screenshots, and info in software centers like Discover or GNOME Software. You can fix it by doing what Konna (post #12) said here.

It's the same issue we had here. https://dev1galaxy.org/viewtopic.php?id=4726

Long story short, Devuan doesn't have an appstream database like Debian does to get package information in Discover or GNOME software.

You could try Ristretto which is the Xfce image viewer, as far as I know it should follow xfce4's settings more so than eom because of xfconf.

It's hard to believe this was a real thing when I first heard of it several weeks ago.

It does appear that I am.

I have tried every combination that qv4l2 would let me to no avail. The wires don't appear broken. This adapter never really got used before so its almost like brand new, because about a year ago is when I first received it and gave it a try and it wouldn't even appear as a device in Linux. I never got around to checking out why but most likely I was missing the module. Now that I have the time to try it again, it appears in dmesg and generates video devices but unfortunately it seems to be a paperweight.

I tried to run ffmpeg with sudo but get the same exact /dev/video0: Input/output error. When I try /dev/video1 it results in not a video capture device

After issuing chmod a+r to video0 & video1 they both still give the same respective errors.

I used your revised script but it still gives the same output for both video0 and video1, albeit with the deprecated warning gone.

Yes, that's what I used to see those options.

Thanks, I just tried that qv4l2 tool and followed the article but I get a black screen even with the VCR turned on.
After the first try with YUYV as the capture format, it switches to Motion-JPEG and won't let me pick anything but that. MJPG doesn't show anything either though.

If anything, my device doesn't appear as usbtv but instead "Camera 1".
