We’ve already implemented this with this script and we’ve added a “Download” button. The script generates a video file with the presentation and audio track, nothing more. In general BBB has no concept of a file that represents a complete recording, as a recording consist of audio, webcams, chat, presentation, whiteboard… So we have to decide what needs to be in this file, for now presentation+audio seems to be enough from my POV, but I never had much to do with recordings of video calls.
