(roomId is wrongly named, and designates room’s slug)

Room’s slug are passed in filenames to simplify post-processing. Thus, from filename,
we can retrieve the room being recorded.

Current limitation: audio tracks are mixed, requiring diarization.
Future plans include full audio + video recording for a more complete meeting experience.
