How to set path for virtual camera

[Sp3rick_hj]

I need to use multiple virtual cameras, so i need to set a path with /dev/video2 (in my device its default) and another with /dev/video3, i already loaded v4l2loopback module from https://github.com/umlaeute/v4l2loopback but i dont find any option that allow to change it

Obs will always use the first virtual camera. You cannot set it. You will have to set it in other apps to use higher numbered camera devices.

I have this in a script, that is called from root's crontab @reboot (sudo crontab -e to edit the schedule):
modprobe v4l2loopback exclusive_caps=1 card_label='OBS Virtual Camera' video_nr=99
That's copied from OBS's source code, so it's exactly what OBS wants, except I added the video_nr=99 to keep it from rearranging my physical cameras.

That works, but I haven't tried multiple VCams from OBS. YMMV on that.

Originally, that was to prevent OBS asking for my password, since that's what it was for. By having it already active, OBS just uses it.
