Another new release of the excellent open source video capture and streaming app OBS Studio is being prepared, with OBS Studio 32.1 Beta out now. You can get testing with a few new features and tweaks to existing features.

The main new features for this release include a new Audio Mixer, a new Add Source dialog, WebRTC Simulcast support and they added missing undo/redo actions for scene items. WebRTC Simulcast sounds like quite a fun one, allowing for multiple quality levels to be sent over one track in WebRTC. Similar in a way to what Twitch have with Enhanced Broadcasting.
