4.6.2 (November 5, 2021)

Enhancements

• Added support for Audio Only rooms.
• Improved reconnection time after network connectivity disruptions.
• This release is built with Xcode 12.5.1

API Changes

• Two new error codes TVIErrorRoomAudioOnlyFlagNotSupportedError (53124) and TVIErrorRoomTrackKindNotSupportedError (53125) are added to support Audio Only rooms.

Known Issues

• Audio playback fails when running a simulator on a Mac Mini. #182
• 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]
