LocalTrackUnpublished: = "localTrackUnpublished"

A local track was unpublished. This event is helpful to know when to remove the local track from your UI.

ParticipantMetadataChanged

ParticipantMetadataChanged: = "participantMetadataChanged"

Participant metadata is a simple way for app-specific state to be pushed to all users. When RoomService.UpdateParticipantMetadata is called to change a participant's state, all participants in the room will fire this event. To access the current metadata, see Participant.metadata.

args: (prevMetadata: string)

args: (TrackPublication)

TrackPublished

TrackPublished: = "trackPublished"

When a new track is published to room after the local participant has joined. It will not fire for tracks that are already published.

A track published doesn't mean the participant has subscribed to it. It's simply reflecting the state of the room.

args: (RemoteTrackPublication)

TrackStreamStateChanged

TrackStreamStateChanged: = "trackStreamStateChanged"

StreamState indicates if a subscribed track has been paused by the SFU (typically this happens because of subscriber's bandwidth constraints)

When bandwidth conditions allow, the track will be resumed automatically. TrackStreamStateChanged will also be emitted when that happens.

args: (pub: RemoteTrackPublication, streamState: Track.StreamState)

Successfully subscribed to the RemoteParticipant's track. This event will always fire as long as new tracks are ready for use.
