audioVideoWasDemotedFromPrimaryMeeting

  • This observer callback will only be called for attendees in Replica meetings.

    Indicates that the client is no longer authenticated to the Primary meeting and can no longer share media. status will contain a MeetingSessionStatusCode of the following:

    • MeetingSessionStatusCode.OK: demoteFromPrimaryMeeting was used to remove the attendee.
    • MeetingSessionStatusCode.AudioAuthenticationRejected: chime::DeleteAttendee was called on the Primary meeting attendee used in promoteToPrimaryMeeting.
    • MeetingSessionStatusCode.AudioVideoDisconnectedWhilePromoted: The client disconnected (and may be reconnecting). Any disconnection will trigger an automatic demotion to avoid unexpected or unwanted promotion state on reconnection.

    Parameters

    Returns void

bindAudioElement

  • bindAudioElement(element: HTMLAudioElement): Promise<void>

bindVideoElement

  • bindVideoElement(tileId: number, videoElement: HTMLVideoElement): void

captureVideoTile

  • captureVideoTile(tileId: number): ImageData

chooseAudioOutput

  • chooseAudioOutput(deviceId: string): Promise<void>

chooseVideoInputQuality

  • chooseVideoInputQuality(width: number, height: number, frameRate: number): void

createAnalyserNodeForAudioInput

demoteFromPrimaryMeeting

  • demoteFromPrimaryMeeting(): void
  • 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 AudioVideoObserver.audioVideoWasDemotedFromPrimaryMeeting but there is no need to wait for that callback to revert UX, etc.

    Returns void

enableSVCForContentShare

  • enableSVCForContentShare(enable: boolean): void

enableSimulcastForContentShare

getAllRemoteVideoTiles

getAllVideoTiles

getCurrentMeetingAudioStream

  • getCurrentMeetingAudioStream(): Promise<MediaStream>

getLocalVideoTile

getRTCPeerConnectionStats

  • getRTCPeerConnectionStats(selector?: MediaStreamTrack): Promise<RTCStatsReport>
  • This API will be deprecated in favor of ClientMetricReport.getRTCStatsReport().

    It makes an additional call to the getStats API and therefore may cause slight performance degradation.

    Please subscribe to metricsDidReceive(clientMetricReport: ClientMetricReport) callback, and get the raw RTCStatsReport via clientMetricReport.getRTCStatsReport().

    Parameters

    • Optional selector: MediaStreamTrack

    Returns Promise<RTCStatsReport>

getRemoteVideoSources

getVideoInputQualitySettings

getVideoTile

hasStartedLocalVideoTile

  • hasStartedLocalVideoTile(): boolean

listAudioInputDevices

  • listAudioInputDevices(forceUpdate?: boolean): Promise<MediaDeviceInfo[]>

listAudioOutputDevices

  • listAudioOutputDevices(forceUpdate?: boolean): Promise<MediaDeviceInfo[]>

listVideoInputDevices

  • listVideoInputDevices(forceUpdate?: boolean): Promise<MediaDeviceInfo[]>

mixIntoAudioInput

  • mixIntoAudioInput(stream: MediaStream): MediaStreamAudioSourceNode

pauseContentShare

  • pauseContentShare(): void
  • Pause content sharing. This (combined with unpauseContentShare is a lightweight alternative to stopping and starting content share which requires use of a seperate peer connection and therefore has increased latency.

    Remote receivers will continue to subscribe to content share video but there will be nothing transmitting (e.g. it may be a black frame)

    Returns void

pauseVideoTile

  • pauseVideoTile(tileId: number): void

promoteToPrimaryMeeting

  • Allows an attendee in a Replica meeting to immediately transition to a Primary meeting attendee without need for reconnection. The promise should always return a session status even upon failure (i.e. it should never reject). See the guide for more information.

    The resolved MeetingSessionStatus will contain a MeetingSessionStatusCode of the following:

    • MeetingSessionStatusCode.OK: The promotion was successful (i.e. session token was valid, there was room in the Primary meeting, etc.), audio will begin flowing and the attendee can begin to send data messages, and content/video if the call is not already at limit.
    • MeetingSessionStatusCode.AudioAuthenticationRejected: Credentials provided were invalid when connection attempted to Primary meeting. There may be an issue with your mechanism which allocates the Primary meeting attendee for the Replica meeting proxied promotion. This also may indicate that this API was called in a non-Replica meeting.
    • MeetingSessionStatusCode.AudioCallAtCapacity: Credentials provided were correct but there was no room in the Primary meeting. Promotions to Primary meeting attendee take up a slot, just like regular Primary meeting attendee connections and are limited by the same mechanisms.
    • MeetingSessionStatusCode.SignalingBadRequest or MeetingSessionStatusCode.SignalingInternalServerError: Other failure, possibly due to disconnect or timeout. These failures are likely retryable.

    Application code may also receive a callback on AudioVideoObserver.videoAvailabilityDidChange to indicate they can begin to share video.

    chime::DeleteAttendee on the Primary meeting attendee will result in AudioVideoObserver.audioVideoWasDemotedFromPrimaryMeeting 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. If the attendee still needs to be an interactive participant in the Primary meeting, promoteToPrimaryMeeting should be called again with the same credentials.

    This function should not be called until the first one resolves.

    Parameters

    Returns Promise<MeetingSessionStatus>

    Promise which resolves to a session status for the request. See possible options above.

setDeviceLabelTrigger

  • setDeviceLabelTrigger(trigger: () => Promise<MediaStream>): void

setVideoCodecSendPreferences

  • Set codec preferences for this clients send stream in order of most preferred to least preferred. The controller will fallback for one of two reasons

    • The codec is not supported by the browser
    • Another client that has joined the conference does not support receiving the video. Note that if another client does not support any of the codecs provided the sender will not fallback, and that client will not be able to receive from this sender.

    If there is no overlap between what is passed in and what is supported by the browser, this function may not have any effect, and the default set of codecs for this browser will be used.

    Parameters

    Returns void

setVideoMaxBandwidthKbps

  • setVideoMaxBandwidthKbps(maxBandwidthKbps: number): void

start

  • start(options?: { signalingOnly?: boolean }): void
  • Start the meeting session. By default this will connect and begin sending and receiving audio, depending on the implementation.

    This method also allows you to provide options for how connection occurs.

    The only supported option is signalingOnly. Specifying this option will cause the controller to only connect the meeting signaling channel. This can be performed relatively early in the join lifecycle (e.g., prior to choosing audio devices), which can improve join latency.

    Your code is responsible for calling start again without signalingOnly to complete connection.

    Parameters

    • Optional options: { signalingOnly?: boolean }
      • Optional signalingOnly?: boolean

    Returns void
