Managing recorders

Technically everything hangs on a recorder: its stream is checked, events and incidents belong to it. What you see everywhere is the room name.

Administration → Recorders lists all recorders with room name, stream name, Opencast agent, status and whether they are active.

Adding and editing recorders

Add recorder opens a form; the pencil on a row edits an existing recorder.

Field	Meaning
Room name	What the room is called everywhere in ansehBAR, e.g. “Lecture Hall A”.
Stream name	Name of the stream on the streaming server. Upper and lower case matter.
Opencast agent	The capture agent in Opencast; empty if not linked. Usually the same as the stream name.
Alarm mode	See below.
Active	Only active recorders are checked and shown.

New from Opencast

With the Opencast connection, ansehBAR creates a recorder for every new capture agent. It has no room name yet and is marked New – please check. Enter a room name and save — or deactivate the recorder if it is not needed.

Sync Opencast now fetches agents and events immediately instead of waiting for the next regular sync. ansehBAR only reads.

Alarm mode

Mode	Alarm “Stream missing”
On time (Opencast start)	when the stream is missing at the Opencast start plus the grace period (3 min by default)
Grid (c.t.)	at the earliest at slot start plus c.t. plus tolerance — for rooms that book differently or start later
Off (log only)	no alarm; incidents still appear in the timeline and calendar

The matching times are under Settings.

Deactivating and deleting

• Deactivate takes a recorder out of checking and the overview; its history stays.
• Only deactivated recorders can be deleted. Its events and incidents disappear with the recorder.
• If the recorder came from Opencast, its agent goes onto the list Ignored Opencast agents so the sync does not create it again. “Allow again” undoes that.
