"Hello, friends! This is a user who loves OBS Studio. I am facing a problem that has already been reported, but I haven't found any solution that works, either here in the forum or on other sites like YouTube or tutorial websites. So, I will rephrase the question: how can I resolve the output issue when trying to start the virtual camera in OBS Studio? I am using Kali Linux. It's been 6 days since the new version was released, and in the previous version of Kali Linux, the error occurred during the live stream initialization. Now, the error happens when initializing the virtual camera. I want to clarify that I am not a regular user; I've been using OBS Studio on Linux systems for about 8 years. I know how to install its components and compile its plugins. In the last two years, the OBS community has been neglecting the Linux version and focusing only on fixing update issues for Windows. Please, if anyone knows how to resolve this issue, could you provide a plausible step-by-step guide in the response? I've already tried changing the video output code, and I've seen complaints about the same issue with no answers. Please help me! I switched to Windows last month because of these issues with OBS. I use OBS Studio a lot and don't want to switch operating systems, as it worked perfectly on Linux. Now, in recent months, when it's not one issue, it's another. I look forward to the response! Thank you."

I am using Debian (I think Kali is a Debian-based distro; so this could be of help). I just wasted lots of hours trying to fix the same problem.

At last I assumed that the problem was due to the v4l2loopback packages recently upgraded from version 0.13.2-1 to 0.14.0-1.
I needed to add the bookworm-backports repository to my Debian system and downgrade the packages with this command:
$ sudo apt install v4l2loopback-dkms=0.13.2-1~bpo12+1 v4l2loopback-source=0.13.2-1~bpo12+1 v4l2loopback-utils=0.13.2-1~bpo12+1

And I used this other command to avoid accidental upgrades until someone fixes this.
$ sudo apt-mark hold v4l2loopback-dkms v4l2loopback-source v4l2loopback-utils

You can see the most similar versions for your distro with commands like:
$ apt -a show v4l2loopback-dkms v4l2loopback-source v4l2loopback-utils

or, if it's installed,

$ aptitude versions v4l2loopback-dkms v4l2loopback-source v4l2loopback-utils

You'll need to look into this further to adapt these commands. Debian and Kali are not the same distro.
