Start AudioVideo Controller

Stop AudioVideo Controller. This will exit the meeting

Start local video and begin transmitting frames from an internally held DefaultCameraCaptureSource. stopLocalVideo will stop the internal capture source if being used.

Calling this after passing in a custom VideoSource will replace it with the internal capture source.

This function will only have effect if start has already been called

Start local video with configurations and begin transmitting frames from an internally held DefaultCameraCaptureSource. stopLocalVideo will stop the internal capture source if being used.

Calling this after passing in a custom VideoSource will replace it with the internal capture source.

This function will only have effect if start has already been called If maxBitRateKbps is not set, it will be self adjusted depending on number of users and videos in the meeting

Start local video with a provided custom VideoSource which can be used to provide custom VideoFrames to be transmitted to remote clients. This will call VideoSource.addVideoSink on the provided source.

Calling this function repeatedly will replace the previous VideoSource as the one being transmitted. It will also stop and replace the internal capture source if startLocalVideo was previously called with no arguments.

This function will only have effect if start has already been called

Start local video with configurations and a provided custom VideoSource which can be used to provide custom VideoFrames to be transmitted to remote clients. This will call VideoSource.addVideoSink on the provided source.

Calling this function repeatedly will replace the previous VideoSource as the one being transmitted. It will also stop and replace the internal capture source if startLocalVideo was previously called with no arguments.

This function will only have effect if start has already been called If maxBitRateKbps is not set, it will be self adjusted depending on number of users and videos in the meeting

Stops sending video for local attendee. This will additionally stop the internal capture source if being used. If using a custom video source, this will call VideoSource.removeVideoSink on the previously provided source.

Enable remote video to start receiving streams

Subscribe to audio, video, and connection events with an AudioVideoObserver.

Unsubscribes from audio, video, and connection events by removing specified AudioVideoObserver.

Subscribe to metrics events with an MetricsObserver.

Unsubscribes from metrics events by removing specified MetricsObserver.

Add, update, or remove subscriptions to remote video sources provided via remoteVideoSourcesDidBecomeAvailable.

This function requires using the RemoteVideoSource provided by remoteVideoSourcesDidBecomeAvailable, otherwise it will not update properly. This is what allows to use the RemoteVideoSource objects as keys in a map.

Including a RemoteVideoSource in addedOrUpdated which was not previously provided will result in the negotiation of media flow for that source. After negotiation has completed,videoTileDidAdd on the tile controller will be called with the TileState of the source, and applications can render the video via ‘bindVideoTile’. Reincluding a RemoteVideoSource can be done to update the provided VideoSubscriptionConfiguration, but it is not necessary to continue receiving frames.

Including a RemoteVideoSource in removed will stop the flow video from that source, and lead to a videoTileDidRemove call on the tile controller to indicate to the application that the tile should be unbound. To restart the flow of media, the source should be re-added by including in addedOrUpdated. Note that videos no longer available in a meeting (i.e. listed in remoteVideoSourcesDidBecomeUnavailable do not need to be removed, as they will be automatically unsubscribed from.

Note that before this function is called for the first time, the client will automatically subscribe to all video sources. However this behavior will cease upon first call (e.g. if there are 10 videos in the meeting, the controller will subscribe to all 10, however if updateVideoSourceSubscriptions is called with a single video in addedOrUpdated, the client will unsubscribe from the other 9. This automatic subscription behavior may be removed in future major version updates, builders should avoid relying on the logic and instead explicitly call updateVideoSourceSubscriptions with the sources they want to receive.

Allows an attendee in a Replica meeting to immediately transition to a Primary meeting attendee without need for reconnection.

PrimaryMeetingPromotionObserver.didPromoteToPrimaryMeeting will be called exactly once on observer for each call. If the promotion is successful, PrimaryMeetingPromotionObserver.didDemoteFromPrimaryMeeting will be called exactly once if/when the attendee is demoted. See the observer documentation for possible status codes.

Application code may also receive a callback on AudioVideoObserver.videoSessionDidStartWithStatus without MeetingSessionStatusCode.VideoAtCapacityViewOnly to indicate they can begin to share video.

chime::DeleteAttendee on the Primary meeting attendee will result in PrimaryMeetingPromotionObserver.didDemoteFromPrimaryMeeting to indicate the attendee is no longer able to share.

Any disconnection will trigger an automatic demotion to avoid unexpected or unwanted promotion state on reconnection. This will also call PrimaryMeetingPromotionObserver.didDemoteFromPrimaryMeeting; if the attendee still needs to be an interactive participant in the Primary meeting, promoteToPrimaryMeeting should be called again with the same credentials.

Note that given the asynchronous nature of this function, this should not be called a second time before PrimaryMeetingPromotionObserver.didPromoteToPrimaryMeeting is called for the first time. Doing so may result in unexpected behavior.

Remove the promoted attendee from the Primary meeting. This client will stop sharing audio, video, and data messages. This will revert the end-user to precisely the state they were before a call to promoteToPrimaryMeeting

This will have no effect if there was no previous successful call to promoteToPrimaryMeeting. This may result in PrimaryMeetingPromotionObserver.didPromoteToPrimaryMeeting but there is no need to wait for that callback to revert UX, etc.
