Twilio Video SDK iOS 2.9.0

This release consumes twilio-video-cpp-3.4.0.

API Changes

• Implemented the Network Quality functionality for Group Rooms:
  • To enable the Network Quality functionality, set the TVIConnectOptions.networkQualityEnabled property to YES when connecting to a Group Room.
  • To determine the current network quality level for your Local Participant, query the TVILocalParticipant.networkQualityLevel. Note, this will return TVINetworkQualityLevelUnknown if:
    • The TVIConnectOptions.networkQualityEnabled property was set to NO OR
    • Using a Peer-to-Peer room OR
    • The network quality level has not yet been computed
  • Network Quality Level for Remote Participants will be available in a future release.
  • Implementing [TVILocalParticipantDelegate localParticipant:networkQualityLevelDidChange:] method on your TVILocalParticipantDelegate will allow you to receive callbacks when the network quality level changes.

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

...

// MARK: TVILocalParticipantDelegate
func localParticipant(_ participant: TVILocalParticipant, didChange networkQualityLevel: TVINetworkQualityLevel) {

    print("Network Quality Level Changed: \(networkQualityLevel)")
}

Known Issues

• When network quality is enabled and the Client reconnects to a Room, it sends extra network quality messages to Twilio's Servers. [CSDK-2876]
• Unpublishing and republishing a TVILocalAudioTrack or TVILocalVideoTrack might not be seen by Participants. #34
• Typically, a maximum of three H.264 encoders can be used at once. When this limit is exceeded no errors are raised and new video Tracks are not encoded. #17
• 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]
• Participant disconnect event can take up to 120 seconds to occur. #99
