I fixed the sources link, here is my fork: https://github.com/LevitatingBusinessMan/droidcam-aur

And here's a link to the PKGBUILD commit as a patch: https://github.com/LevitatingBusinessMan/droidcam-aur/commit/a9e6ce047393a77942ee4571edfc1f9ede97d7d0.patch

Edit: I also added the fix @yochiwarez mentioned to the repository. You can download that commit as a patch here: https://github.com/LevitatingBusinessMan/droidcam-aur/commit/4586966807ed0cbcd1b8e1491acdff53ad724907.patch

Why xanmod kernel, and 4.9, and 4.14, and 3.16 ? This is madness !

for those who have this error Device not found (/dev/video[0-9]). change MODPATH in the pkgbuild file, like this : MODPATH="/usr/lib/modules/$(uname -r | sed 's/.[0-9]+-[0-9]+//')/extramodules"

it will work after reboot.

Same issue, Error: Device not found (/dev/video[0-9]). I installed and loaded v4l2loopback-dkms, it didn't help.

Hi, I run into the exact same problem of Error: Device not found (/dev/video[0-9]). Yes, my kernel goes along the headers ... This is my dif from the build: diff --git a/PKGBUILD b/PKGBUILD index fba59b6..a3d8c03 100644 --- a/PKGBUILD +++ b/PKGBUILD @@ -54,7 +54,7 @@ package() {

The module is installed into the wrong directory when using recent kernel versions I guess. I had to change the PKGBUILD and droidcam.install to point to "/usr/lib/modules/extramodules-ARCH".

getting

Error: Device not found (/dev/video[0-9]). Did you install it?
