Twilio Video SDK iOS 2.8.0

This release consumes twilio-video-cpp-3.3.0.

API Changes

• Implemented the Dominant Speaker functionality for Group Rooms. To enable the dominant speaker functionality, set the TVIConnectOptions.dominantSpeakerEnabled property to YES when connecting to a Group Room. To determine the current dominant speaker, query the TVIRoom.dominantSpeaker property. When there is no dominant speaker, the TVIConnectOptions.dominantSpeakerEnabled property was set to NO or when using a Peer-to-Peer room, the TVIRoom.dominantSpeaker property will always return nil. When there is a dominant speaker, the TVIRoom.dominantSpeaker property will return the appropriate TVIRemoteParticipant. Implementing [TVIRoomDelegate room:dominantSpeakerDidChange:] method on your TVIRoomDelegate will allow you to receive callbacks when the dominant speaker in a Group Room changes. The dominantSpeakerDidChange: argument will contain the TVIRemoteParticipant of the dominant speaker, or nil if there is no longer a dominant speaker.

@IBAction func connectToRoom(sender: AnyObject) {
    let connectOptions = TVIConnectOptions(token: accessToken) { (builder) in
        builder.dominantSpeakerEnabled = true
        builder.roomName = "my-room"
    }
    room = TwilioVideo.connect(with: connectOptions, delegate: self)
}

...

// MARK: TVIRoomDelegate
func room(_ room: TVIRoom, dominantSpeakerDidChange participant: TVIRemoteParticipant?) {
    var identity = "N/A"

    if let participant = participant {
        identity = participant.identity
    }

    print("Dominant Speaker Changed: \(identity)")
}

Bug Fixes

• Fixed a crash related to stats gathering which could occur in the media monitor component. [CSDK-2786]

Known Issues

• Unpublishing and republishing a TVILocalAudioTrack or TVILocalVideoTrack might not be seen by Participants. #34

• Publishing H.264 video at greater than 1280x720 @ 30fps is not supported. If a failure occurs then no error is raised to the developer. [ISDK-1590]
