Make sure you always get the latest release. There is also a video tutorial showing the installation and usage.

Your best bet is to download the installer (Number 1 in the picture), it'll take care of everything (except if you installed obs studio to a custom location you might have to check that the path is correct in the installer). You can also install it manually via the zip archive (Number 2 in the picture). Inside it are three folders. The folder "obs-plugins" and "data" need to go in the root folder of your obs installation:

Now head over to usage for information on how to use the plugin.

• If you're having issues getting the plugin to load you might be missing the Visual C++ Redistributables.
• The plugin does not and will not work with Streamlabs OBS!
• Since this plugin hooks into input you shouldn't open two instances of OBS, because it will result in stuttering input. If you do need two instances, you might want to look into portable mode of obs.

If you use Ubuntu or Debian you can use the .deb installer inside the zip archive (Number 4 in the screenshot). Other distros currently have to either build the plugin from source or extract the binaries from the debian installer and move them into the correct folders manually. If you use the flatpak version of obs I can't help you as I have no experience with it

For Arch-based linux distros:

You should be able to install the plugin via the AUR.

After the installation is done you should see both a new source type in the list of sources as well as a new menu option under tools:

If neither of those options show up OBS couldn't load the plugin. If that is the case make sure that you followed the installation process closely. You can check the OBS log and look for input overlay. It should show up like this
