Audio device and application capture for OBS Studio using PipeWire

This plugin adds 3 sources for capturing audio outputs, inputs and applications using PipeWire

Usage

Requirements

• OBS Studio 28.0 or later
• WirePlumber

PipeWire 0.3.62 or later is highly recommended (#17, PipeWire#2874)

For the plugin to be able to capture applications, PipeWire should be set up to handle audio on your system. For most applications, the pipewire-pulse compatibility layer should be enough, but there are also pipewire-jack and pipewire-alsa. If applications aren't showing up in the plugin, your system may be missing one of those components.

Installation

Flatpak

If you're using the Flatpak version of OBS Studio, install the plugin from Flathub.

flatpak install flathub com.obsproject.Studio.Plugin.PipeWireAudioCapture

If the sources show no devices or apps, run flatpak override --filesystem=xdg-run/pipewire-0 com.obsproject.Studio and restart OBS Studio.
