This release consumes twilio-video-cpp-6.3.0-rc4.

This beta release is for customers to give feedback about Apple Silicon simulator support. Thank you very much for your interest in this feature.

Note: If your app requires more than 10 Participants in a Room then we recommend waiting for the 4.6.0 release.

Features

  • TwilioVideo.xcframework now supports the simulator on Apple Silicon arm64 Macs. #144
    • This results in a size increase for the SDK during development.
    • App store download size is not affected.

Enhancements

  • This release is based on WebRTC M88.
  • The SDK uses Unified Plan SDP semantics instead of Plan-B. This brings several important benefits:
    • Improved interoperability with Firefox, Safari and Chrome in Peer-to-Peer Rooms
    • Track level operations like publishing and unpublishing are more reliable
    • Send side bandwidth estimation is now supported in Group Rooms via transport-cc. Previously, send side bandwidth estimation was only supported in Peer-to-Peer and Go Rooms
  • Improved performance of Room.getStats() by adopting the W3C standardized RTC stats API

API Changes

  • Previously, the ordering of RemoteParticipantDelegate.onAudioTrackSubscribed() and RemoteParticipantDelegate.onVideoTrackSubscribed() was not strictly guaranteed. Now, the ordering of these callbacks may be reversed when compared to previous releases.
  • The value of LocalVideoTrackStats.framesEncoded now reflects the total number of frames encoded for a simulcast track.

Bug Fixes

  • Fixed performance problems with Room.getStats() where block callbacks could sometimes be significantly delayed. [CSDK-3475]
  • Fixed an interoperability issue with twilio-video.js when publishing media in Peer-to-Peer or WebRTC Go Rooms. #931

Known Issues

  • This beta is not recommended in Rooms with > 10 Participants due to increased message sizes. We are working to resolve this size increase before the GA release. [VIDEO-3532]
  • Carthage is not currently a supported distribution mechanism for Twilio Video. Carthage does not currently work with .xcframeworks as documented here. Once Carthage supports binary .xcframeworks, Carthage distribution will be re-added.
  • Unpublishing and republishing a LocalAudioTrack or LocalVideoTrack might not be seen by Participants. #34
  • H.264 video might become corrupted after a network handoff. #147
  • iOS devices do not support more than three H.264 encoders. Refer to #17 for suggested work arounds.
  • 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]
