I'm trying to run it using fedora 31 (5.7.15-100.fc31.x86_64), mon2cam closes after choosing a monitor.

mon2cam -v

I tried running ffmpeg -f x11grab -r 60 -s 1920x1080 -i :0.0+0,0 -pix_fmt yuv420p -f v4l2 /dev/video50 With these results:

I've installed libv4l and v4l-utils, can't find any Fedora repo for v4l2

[botiapa]

Hey,

Try running sudo modprobe -r v4l2loopback I think v4l2 is not properly installed on your system.

[ShayBox]

Yeah, v4l2loopbackis separate from those, it's a kernel module, you'll probably have to manually compile it if it's not available in the repos

[botiapa]

If you do make it work, could you post the results, so we can show the install process in the readme?

[DSVDiniz]

Sorry, gave up on it and changed my distro to debian, fedora had been an uphill battle since I'd installed it.

[botiapa]

Haha :smile:,

Well if you do try out Mon2Cam on debian, and you have problems, don't hesitate to reopen the issue.
