It looks like this plugin is in desperate need of some attention from the developer - especially on MacOS. The latest versions of the plugin, including beta, don't show up in the OBS Studio's Tools menu (v30/v29.1.3) on Apple-Silicon based Macs (m1 etc) and a "can't begin data capture" error occurs on Intel based Macs. It's a shame to see such a wonderfully useful plugin be neglected.
Dear Scot Xu, if you're reading this, it's our wish that you have an opportunity to put some quality time into getting your plugin back into stable working shape with all the current bugs worked out.
Warm regards.
