Ubuntu 20

In this article, we will explore some of the most effective solutions to fix the OBS Studio Virtual Camera not working issue. OBS Studio is a popular software for video recording and live streaming. However, users often encounter problems with the virtual camera feature. Let’s dive into the solutions.

Solution 1: Install OBS Studio and v4l2loopback-dkms

The first step to solve the OBS Studio Virtual Camera not working issue is to install OBS Studio and v4l2loopback-dkms. Here’s how you can do it:

sudo apt install obs-studio v4l2loopback-dkms

In this command, sudo is used to execute the command with root privileges, apt is the package handling utility in Ubuntu, install is the command to install packages, and obs-studio v4l2loopback-dkms are the packages we are installing.

After installation, you should see a “Start Virtual Camera” button in OBS Studio. Click on it and enter your password when prompted.

If the button still says “Start Virtual Camera” and no virtual camera is detected by other applications, it’s time to check if the v4l2loopback module is loaded. You can do this by running the following command:

lsmod | grep v4l2loopback

The lsmod command shows the status of modules in the Linux Kernel and grep is used to filter the output for the term ‘v4l2loopback’. If the module is not loaded, proceed to Solution 2.

Solution 2: Disable Secure Boot

If the v4l2loopback module is not loaded, you may need to disable secure boot. Here’s a detailed guide on how to disable secure boot:

After disabling secure boot, reboot your system. Then, install OBS Studio and v4l2loopback-dkms again using the command:

sudo apt install obs-studio v4l2loopback-dkms

Launch OBS Studio and click on the “Start Virtual Camera” button. It should now work properly.

  1. Update Your System: Make sure your system is up-to-date. You can update your system using the following command:
