[0.25.0] - 2024-03-21

Added

  • Added support for building with Xcode 15.
  • Added privacy manifest files to media and machine learning dependencies.
    • The privacy manifest is a beta feature. Please comment on the linked Github issue for any suggestions or issues encountered related to the privacy manifest: #624

Fixed

  • Fixing a race condition in the SDK layer when SDK is built with Xcode 15.
  • Fixed a SIGABRT crash in the machine learning dependency when SDK is built with Xcode 15.

Removed

  • Breaking Removed support for Bitcode as Xcode 15 has removed support for Bitcode.

    • Migration Guide:
      • If previously building an app with Bitcode, build without bitcode enabled or build with Xcode 15.
      • If downloading binaries from Github, there should be no change in the name of the binary, but note there will only be one binary available for download and it will not contain Bitcode.
      • If downloading directly from the link address used on Github and were previously not using Bitcode, remove the string -without-bitcode from your url strings.
      • If using Cocopods, edit your Podfile to remove -Bitcode and -No-Bitcode from all Amazon Chime SDK pod names.
      • If using SPM, no changes are required.

  • Breaking Removed support for iOS 11. Apps building with the Amazon Chime SDK must target iOS 12 or above.

  • Breaking Removed AudioMode.nodevice, which is now replaced by AudioDeviceCapabilities.none. Apps which previously used AudioMode.nodevice can achieve the same functionality by using AudioDeviceCapabilities.none when constructing an AudioVideoConfiguration, e.g. AudioVideoConfiguration(audioDeviceCapabilities: .none).

  • Breaking DefaultAudioVideoFacade init requires a ContentShareController instance.
  • Update text of additional options on demo app.
  • MeetingSessionURLs and MeetingSessionCredentials now conform to Codable.
  • Changes that support a speed up of video client initialization. videoClientRequestTurnCreds callback will only be invoked as a backup for media layer logic.

Fixed

  • Fix a bug that internal capture source was not stopped properly when the video client was being stopped. (Issue #200)

    • After this fix, the internal video tile mapping entry will be removed before videoTileDidRemove(tileState:) callback is called. Please check your VideoTileObservers and make sure your videoTileDidRemove(tileState:) handlers do not call any SDK APIs that depend on the existance of video tiles (e.g. bindVideoView(videoView:tileId:)).

[0.12.2] - 2020-12-11

[0.12.1] - 2020-11-20

  • Added Amazon Voice Focus feature in Swift demo app.
  • Added more verbose logging from media layer to SDK layer for builders to control log level. Set LogLevel to INFO or above for production application to not be bombarded with logs.
  • Added getActiveAudioDevice API in DefaultDeviceController.
  • Added VideoFrame, VideoRotation, VideoContentHint, VideoFrameBuffer, VideoFramePixelBuffer classes, enums, and interfaces to hold video frames of various raw types.
  • Added VideoSource and VideoSink to facilitate transfer of VideoFrame objects.
  • Added CameraCaptureSource, CaptureSourceError, CaptureSourceObserver, VideoCaptureFormat, and VideoCaptureSource interfaces and enums to facilitate releasing capturers as part of the SDK.

  • Breaking Changed behavior to no longer call videoTileSizeDidChange when a video is paused to fix a bug where pausing triggered this callback with width=0 and height=0.
  • Fixed videoTileDidAdd not being called for paused tiles.

Changed

  • Breaking Changed default log level of ConsoleLogger to INFO.
  • The render path has been changed to use VideoFrames for consistency with the send side, this includes:
    • Breaking VideoTileController.onReceiveFrame now takes VideoFrame? instead of CVPixelBuffer?.
      • Builders with a custom VideoTileController will have to update APIs correspondingly. All current VideoFrame objects used by the SDK will contain VideoFramePixelBuffer buffers, which contain CVPixelBuffers internally.
    • Breaking VideoTile.renderFrame now takes VideoFrame instead of CVPixelBuffer? and has been replaced by extending VideoSink and using onReceivedVideoFrame.
      • Builders with a custom VideoTile will have to update APIs correspondingly. All current VideoFrame objects used by the SDK will contain VideoFramePixelBuffer buffers, which contain CVPixelBuffers internally.
    • Breaking VideoRenderView is now just a VideoSink (i.e. it now accepts VideoFrame object via VideoSink.onReceivedVideoFrame rather then CVPixelBuffer? via render).
      • Builders with a custom VideoTile will have to update APIs correspondingly. All current VideoFrame objects used by the SDK will contain VideoFramePixelBuffer buffers, which contain CVPixelBuffers internally.
  • If no custom source is provided, the SDK level video client will use a DefaultCameraCaptureSource instead of relying on capture implementations within the AmazonChimeSDKMedia framework; though behavior should be identical, please open an issue if any differences are noticed.
  • Added additional, optional id (unique ID) parameter to MediaDevice for video capture devices.

  • Added attendee id to local video tile

Changed

  • Breaking Throw MediaError.audioFailedToStart when AudioClient fails to start
  • Breaking Changed the constructor for DefaultVideoTileController

[0.7.0] - 2020-06-05

Added

  • Breaking Added start(callKitEnabled:) in AudioVideoControllerFacade to accept a Bool type callKitEnabled parameter, which is set to false by default in DefaultAudioVideoFacade. Pass in true if your VoIP call has CallKit integration so that audio session interruptions are properly handled by the SDK.

Changed

  • start() in DefaultAudioVideoFacade now assumes the VoIP call to start has no CallKit integration by default to properly handle audio session interruptions. Use start(callKitEnabled:) to override the default behavior for calls that have CallKit integration.
  • Initializers of all the public SDK classes are now publicly accessible to builders.

Fixed

  • Fixed random crashes caused by concurrency issues.
