As a note to others who may encounter this issue, the update to v4l2loopback-dkms 0.14.0-1, and v4l2loopback-utils 0.14.0-1, have introduced an issue with OBS' virtual camera (linux-v4l2: Fix virtual camera start failure #11906), causing it to fail to start and throwing an error about drivers.
I can confirm downgrading v4l2loopback-dkms (and v4l2loopback-utils if installed) to version 0.13.2-1, using downgrade resolves the issue.
eg:
sudo downgrade v4l2loopback-dkms
@tytan652 is obviously already aware of the issue and involved in the linked pull request.

If you have issue building please try to downgrade
asio
to a version before 1.34.0, this a headers-only library so packages only rely on it as a build-time dependencies.Arch Linux has unfortunately updated
asio
without testing if packages using it would build andwebsocketpp
happens to not work with the newestasio

For those who might ask why
libva-vdpau-driver
was added to conflicts.It is the only way at package level to prevent the user to have segfaults because of this driver. This will not be fixed on OBS side since this is not an OBS issue.
The driver is only loaded with Nvidia cards.
Try
libva-nvidia-driver
if you really need Nvidia decode through VAAPI.tytan652 commented on 2021-05-14 17:49 (UTC) (edited on 2022-07-08 06:03 (UTC) by tytan652)
This package have some dependencies with version check, it will allow you to rebuild the package only when your system is correctly updated. This feature is not enabled on Manjaro.
If you have any issue, please before commenting rebuild this package (a clean build) and try again to make sure it's not because of a library update.
Pamac has a messed up dependency checker, use another AUR helper for the first install.
This AUR package provide OBS with all the missing feature except Twitch, Restream and YouTube integrations.
More explaination here: https://ideas.obsproject.com/posts/1558/
It provide any dependency needed for Wayland support.
It also contains some unmerged PR or backported fix documented in the PKGBUILD.
I'm quite active on OBS discord server (don't PM me directly), so if I saw something that need to be backported I add it.
