-- Module to be enabled under the main MUC component.

-- Destroys a conference room after a configurable timeout (default 20 s,
|
|
-- overridable via services_empty_meeting_timeout) when the room is left
|
|
-- occupied only by backend services — Jibri recorders or transcribers —
|
|
-- with no regular participants remaining.

|
-- Identity is determined by JID prefix (util.lib.lua):
|
|
-- is_jibri(): JID starts with 'recorder@recorder.', 'jibria@recorder.',
|
|
-- or 'jibrib@recorder.'
|
|
-- is_transcriber(): JID starts with 'transcriber@recorder.',
|

-- 'transcribera@recorder.', or 'transcriberb@recorder.'

-- Hook summary:
|
|
-- muc-occupant-joined (-100) — cancel the destroy timer when a regular user
|
|
-- (not jibri, not transcriber) joins.
|
|
-- muc-occupant-left (-100) — start the destroy timer when the leaver is a
|
|
-- regular user and only backend services remain;
|
|
-- skip entirely if the leaver is admin, jibri,
|
|
-- or transcriber, or if breakout_rooms_active.
