Events

Events are broadcast by the server to each connected client when a recognized action occurs within OBS.

An event message will contain at least the following base fields:

update-type String: the type of event.
stream-timecode String (optional): time elapsed between now and stream start (only present if OBS Studio is streaming).
rec-timecode String (optional): time elapsed between now and recording start (only present if OBS Studio is recording).

Timecodes are sent using the format: HH:MM:SS.mmm

Additional fields may be present in the event message depending on the event type.
