[ 113.906380] v4l2loopback: loading out-of-tree module taints kernel.
[ 113.907038] v4l2loopback: number of devices is limited to: 8
[ 113.907472] v4l2loopback driver version 0.12.7 loaded
kernel version: Linux ubuntu 5.15.0-86-generic udev by-id symlinks #96-Ubuntu SMP Wed Sep 20 08:23:49 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
Distribution (+version):
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04.3 LTS
Release: 22.04
Codename: jammy
Steps to reproduce:
lxc launch images:ubuntu/22.04/desktop ubuntu --vm -c limits.cpu=4 -c limits.memory=4GiB my host operating system is running the same OS with v4l2loopback installed in the same way and still has this same issue, maybe it's a recent OS update?
cd Documents; git clone https://github.com/umlaeute/v4l2loopback
cd v4l2loopback
make KCPPFLAGS="-DMAX_DEVICES=20";
sudo make install;
sudo depmod -a;
sudo modprobe v4l2loopback devices=11 or any number higher than 8
I've also tried increasing the MAX_DEVICES define in the v4l2loopback.c script itself.
Observed Results:
I have 8 total video devices in /dev/ and there's an error in dmesg that says number of devices is limited to: 8,
Expected Results:
11 video devices should appear in /dev/
Relevant Code:
I tried looking for this string in the v4l2loopback source code grep -rnw '.' -e 'limited to' but I only find number of initial devices is limited to not number of devices is limited to
