I only can run Virtual Camera once. Whenever i end it and/or try to restart it i get the message, virtual camera can not be startet - see logs. but the logs say nothing else but that...

when i reboot my computer, virtual camera works again, but only once - and the game starts all over...

any ideas?

Regards

Hi @notyourbiz

You need to stop the virtual camera module before attempting to initialize it again. I created the attached script to accomplish this task; I usually use it with Advanced Scene Switcher to run it when the Virtual Camera is stopped. In this context, the script checks if the virtual camera module has been activated and, if so, starts the procedure to deactivate it; otherwise, the script terminates.

I adjusted the Advanced Scene Switcher settings to run only when the camera's condition changes (activated/deactivated), preventing the script from running unnecessarily repeatedly. However, you can also run it manually outside of OBS Studio.

I don't know exactly which Linux Mint distribution you use, but I use 22.2 XFCE. If you use a distribution with a different default terminal, you will need to edit the script for it to work properly.

It's not the best solution, but I believe it helps overcome the issue. I hope it helps.

saludos hermano y muchas gracias...

it indeed helps for the moment. default terminal is gnome-terminal...
since i'm pretty new to OBS i don't know advanced scene switcher jet, but i'll dig into it ;-)

so - obviously this is a bug in the latest release of OBS, since i did not have that problem in 30.0.2

anyways, thx for the moment...

thx again...

but somehow not working for me... script is nor executed...

maybe because i installed OBS as flatpak - that seems to be a little buggy somehow...

EDIT:
OBS executes the script but prompts:
Line 4: lsmod: Command not found
