The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[0.11.0] - 2024-05-31

Added

  • Added VP8 codec for Windows

Fixed

  • Fix unexpected video scaling at rapid resolution changes on Windows
  • Fix a couple of memory leaks
  • Make StartLocalAudio and StopLocalAudio idempotent to prevent sending duplicate audio packets

[0.10.1] - 2024-03-21

Fixed

  • Fixed memory leak when trying to stop a meeting while it is still starting up

[0.10.0] - 2023-11-02

Fixed

  • Fixed video crashes when race condition occurs.
  • Disable audio redundancy by default.

[0.9.0] - 2023-06-15

Added

  • Added AudioProcessor interface
  • Added NoOpAudioProcessor
  • Added DefaultAudioProcessor
    • DefaultAudioProcessor can toggle the high pass filter, echo canceller, noise suppressor, automatic gain controller, and Voice Focus in real-time via GetConfiguration() and SetConfiguration()
  • Added AudioContext interface that replaces AudioDriver
  • Added enable_audio_redundancy option in AudioConfiguration to enable redundant audio encoding (as specified in RFC 2198 https://www.rfc-editor.org/rfc/rfc2198). Redundant audio encoding improves packet loss recovery.
  • Added parsing of remote audio rtc stats inside VideoClientRtcStatsAdapter.
  • (Breaking) Added codecPreference in AddLocalVideo API of AudioVideoController
  • Added AddInputNode, AddOutputNode, RemoveInputNode, RemoveOutputNode to AudioContext
  • Use implementation of AudioNode for sending and receiving data to/from the media server
  • Move AudioProcessor and AudioResampler into AudioContext
  • Allow AudioProcessor injection through AudioContextFactory
  • Added PrefixLogger class to add prefixes to logging output

Fixed

  • Remove references to pinpoint.
  • Fixed the issue where media client did not stop when server stops.
  • Upgraded libwebsockets to fix retry issue.

Removed

  • (Breaking) Remove AudioSource and AudioSink
  • (Breaking) Remove AddLocalAudioSink, RemoveLocalAudioSink, AddRemoteAudioSink, RemoveRemoteAudioSink
  • (Breaking) Remove OnLocalAudioSourceAvailable and OnRemoteMixedAudioSourceAvailable from AudioVideObserver

[0.8.0] - 2023-02-03

Added

  • Added size_y_, size_u_, and size_v_ to I420VideoFrameBuffer

Fixed

  • (Breaking) Fixed incorrect values for I420VideoFrameBuffer. Previously, values for size_y_, size_u_, and size_v_ were used as the values for stride_y_, stride_u_, and stride_v_. Anything relying on size values being used for strides now needs to calculate size or use the newly provided fields
  • Fixed width_ and height_ values missing for I420VideoFrameBuffer

[0.7.0] - 2022-09-16

Added

  • On AudioVideoController, added SetLocalAudioMute
  • On AudioVideoController, added AddRemoteAudioSink and RemoveRemoteAudioSink. These are additional ways to add audio sinks. One can still add audio sinks with OnRemoteAudioSourceAvailable.
  • On AudioVideoObserver, added OnLocalAudioSourceAvailable
  • CVPixelVideoFrameBuffer used for iOS and OSX specific VideoFrames
  • AudioDriver and associated classes/structs in audio_driver.h. Internally system specific drivers will be used unless custom driver is injected.
  • Custom AudioDriver added to MeetingSessionDependencies in order to allow AudioDrivers to be injected
  • kFloat32 added as additional audio sample format type for SampleFormat
  • PullAudio method added to RemoteAudioSource
  • LocalAudioSource, an implementation of AudioSource

Changed

  • (Breaking) On AudioVideoController, AddLocalAudioSink replaces AddLocalAudio and Modality is passed in directly. AudioSink replaces AudioSource as a parameter
  • (Breaking) On AudioVideoController, RemoveLocalAudioSink replaces RemoveLocalAudio
  • (Breaking) On AudioVideoObserver, OnLocalAudioSourceAvailable replaces OnLocalAudioSourceBecameAvailable
  • (Breaking) On AudioVideoObserver, OnAudioVideoSessionConnecting replaces AudioVideoSessionDidStartConnecting
  • (Breaking) On AudioVideoObserver, OnAudioVideoSessionStarted replaces AudioVideoSessionDidStart
  • (Breaking) On AudioVideoObserver, OnAudioVideoSessionStopped replaces AudioVideoSessionDidStop
  • (Breaking) On AudioVideoObserver, OnRemoteAudioSourceBecameAvailable replaces OnRemoteMixedAudioSourceAvailable

Removed

  • (Breaking) Removed AudioSourceConfiguration
  • Removed usage of Unified Plan video client flag which no longer exists.

[0.6.0] - 2022-02-09

Added

  • Added DataMessageDispatcher to help dispatch messages by topic.
  • Added support for integration with Amazon Transcribe and Amazon Transcribe Medical for live transcription. The Amazon Chime Service uses its active talker algorithm to select the top two active talkers, and sends their audio to Amazon Transcribe (or Amazon Transcribe Medical) in your AWS account. User-attributed transcriptions are then sent directly to every meeting attendee via data messages. Use transcriptions to overlay subtitles, build a transcript, or perform real-time content analysis. For more information, visit the live transcription guide.
  • Added RemoteVideoSource as part of a replacement for removing BindVideoSink and UnbindVideoSink from AudioVideoController. You can call RemoteVideoSource's AddVideoSink and RemoveVideoSink instead of AudioVideoController's BindVideoSink and UnbindVideoSink.
  • Added OnRemoteVideoSourceUnavailable callback to AudioVideoObserver.
  • Added support for receiving stereo audio.

Changed

  • (Breaking) Changed OnRemoteVideoSourceAvailable to OnRemoteVideoSourcesAvailable. Also changed the parameter from a shared pointer to a RemoteVideoSource to a vector of shared pointers to RemoteVideoSource. This is part of the changes to replace BindVideoSink and UnbindVideoSink.

Removed

  • (Breaking) Removed BindVideoSink and UnbindVideoSink from AudioVideoController. See replacement RemoteVideoSource and changes to OnRemoteVideoSourceAvailable for details on how the replacement works
