OBS PipeWire Audio Capture

This plugin (by dimtpap) brings per-application and per-device audio capture to OBS Studio on Linux through PipeWire — letting you grab a single app’s sound on its own track, the Linux counterpart to the Windows application-audio plugins. Recent OBS versions have added native PipeWire audio capture on Linux, so on a current OBS you may not need a separate plugin, but it still serves older versions and setups the built-in option doesn’t cover. Free and open-source.
