This section goes over installing and setting up OBS on your system.
Open up a terminal and type in this command:
sudo dnf install obs-studio
This should download and install OBS on your system.
After downloading and installing it, you can open it and set it up as per usual.
On Wayland, you can capture specific windows or displays with the Screen Capture (PipeWire) source.
On X11, use the Window Capture (Xcomposite) source.
If you plan on using window resizing scripts on X11, it is recommended to set your Minecraft capture source to be centered. After adding Minecraft, select it and press Ctrl+E to open the transform settings - here, click "Reset", then set "Positional Alignment" to "Center". Finally, close the transform settings and press Ctrl+D.
If you are using classic wall (i.e. multi-instancing on versions without SeedQueue), you might want to look at these docs to setup OBS to work with resetti.
Read ahead to set up audio splitting (useful for removing music from your Twitch VODs to avoid copyright, or only capturing game audio in your recordings).
As of right now, OBS on Linux does not support application-specific audio capture out of the box - we instead use an OBS plugin to achieve this.
Download and install the plugin using the instructions here.
After installing the plugin and restarting OBS, check the list of sources. You should see the "Application Audio Capture (PipeWire)" source at the top - after adding it, select the app to capture audio from in the Applications dropdown.
Make sure to mute/disable desktop audio afterwards.
