Changelog: Twilio Video iOS Latest

The Twilio Programmable Video SDKs use Semantic Versioning.

5.2.0 (August 24, 2022)

バグ修正

• Max video bandwidth limits are now applied to each simulcast layer when simulcast is enabled, and the expected behavior for max video bitrates with simulcast is better documented.
• Fixed several bugs that could cause crashes and deadlocks when a Room is disconnected / destroyed.
• Fixed a use-after-free bug associated with tasks posted to TaskQueue that could lead to undefined behavior.
• Fixed a bug which could cause a crash in IceConnectionActivityMonitor when reconnecting to or disconnecting from a Room.
• Fixed a race condition where subscribed callbacks for Remote Participant could be raised for tracks that have been ended.

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]

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.

バグ修正

• Fixed a bug which could occur when connected to a Peer-to-Peer or Go Room and publishing a second video track before another Participant joins, causing the connection to be terminated or the second video track not to be fully established.
• Fixed a bug which could cause the Room connection to be terminated by the server.
• Fixed a bug which could cause the media connection not to be re-established after network changes.
• Fixed a bug where audio fails to start in the iOS Simulator on M1 Mac Mini when no microphone is present.
