Thansk for uploading the new obs version with virtual camera support.

Unfortunately it's not working in Debian:

warning: v4l2loopback not installed, virtual camera disabled

The reason is that the code tries to use modinfo which is not in
$PATH in Debian.

Upstream issue:
https://github.com/obsproject/obs-studio/issues/3845

Trivial patch attached.

Note that this also affects modinfo, which is used in the other file
relevant for virtual camera support; this doesn't affect me as I have
v4l2loopback already loaded.

The whole virtualcam support currently is a bit fragile (trying to
load kernel modules, always using the first of potentially several
/dev/video* devices … I wonder if a README would make sense, and I'd
be happy to provide a draft.


Cheers,
gregor
