Changelog: Twilio Video iOS Latest

The Twilio Programmable Video SDKs use Semantic Versioning.

5.1.0 (March 14, 2022)

機能

• This release introduces Adaptive Simulcast along with new Video Encoding modes for publishers. Adaptive Simulcast reduces publisher resource usage by only sending those encodings for a video track that are needed by subscribers or by the media server (when recording is enabled). This is an opt-in feature and can be enabled by setting the new Connect Option videoEncodingMode to auto, which allows the SDK to select video codecs, use adaptive simulcast and manage encodings automatically. This feature cannot be used alongside EncodingParameters.maxVideoBitrate.

API の変更点

• Added the videoEncodingMode property to ConnectOptions.
• The videoEncodingMode API is mutually exclusive with existing codec management APIs EncodingParameters.maxVideoBitrate and preferredVideoCodecs.

既知の問題

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