All notable changes to this project will be documented in this file.

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

• MediaFactory.audioSession to use instead of deprecated AudioSession.shared

• Support audio in screen capture
• Make it possible to set preferred aspect ratio

• MediaFactory.audioSession to use instead of deprecated AudioSession.shared

• Fix audio configuration for screen capture
• Don't check for host on mute/unmute
• Support cancellation in DNS lookup
• Use different audio session mode for audio and video calls

• Remove various deprecated methods and types

• New AudioSession class for configuring audio on iOS
• New customization options for VideoComponent: background color, corner radius
• Sort SRV records according to RFC 2782 specs

• BREAKING: MediaConnection.secureCheckCode is now a publisher
• BREAKING: All functions in MediaConnection are now async
• Update WebRTC to M115
• Make it possible to create WebRTCMediaFactory with video encoder and decoder factories
• Use RTCDefaultVideoEncoderFactory and RTCDefaultVideoDecoderFactory as default factories on all platforms

• Fix DNSServiceProcessResult crash
• Fix Xcode 15 warnings
• Fall back to .invalidPin error on 403
• Fix creating conference address with uri

• Remove various deprecated methods and types

• VideoComponent can be created with custom setRenderer closure
• Support external cameras on macOS
• ConferenceAddress can be created with alias and host with no extra validation
• MediaConnection.receiveMainRemoteAudio and MediaConnection.receiveMainRemoteVideo to enable remote audio/video
• MediaConnection.setMainDegradationPreference and MediaConnection.setPresentationDegradationPreference that let one specify the desired behavior in low bandwidth conditions
• MediaConnection.setMaxBitrate that controls maximum bitrate for each video stream

• NodeResolver now returns a host name instead of IP adress if A-record is found (fixes the issue with a certificate mismatch when the certificate is not configured to allow multi-domain)
• Don't stop video capture on switching between front and back cameras in WebRTCCameraVideoTrack
• Use default WebRTC bundle policy
• Print a warning if Infinity version prior to v29 is detected. This will be a hard requirement in Q4 2023

• DeviceAlias is renamed to DeviceAddress
• ack is now called later in the call setup phase
• BREAKING: MediaConnection.setMainAudioTrack and MediaConnection.setMainVideoTrack are now throwing functions, and no longer enable remote audio/video by default. Please use MediaConnection.receiveMainRemoteAudio and MediaConnection.receiveMainRemoteVideo to enable them.

• Prevent data races when reading/writing to arrays with ice candidates in WebRTCMediaConnection
• Filter out windows without bundle ID in ScreenMediaSourceEnumerator on macOS

• Removed various deprecated methods

• Screen capture:
  • Make it possible to start capture session not only from the app, but also from the iOS control center while on an active call
  • Introduce keep-alive time in order to stop broadcast extension, started from the iOS control center, when there are no active calls
  • Add more broadcast error types and the API to finish screen capture session with reason, such as callEnded or presentationStolen. See ScreenMediaTrack.stopCapture(reason:)

• Screen capture: change IPC on iOS from Unix domain sockets to memory-mapped file
• Deprecate ScreenMediaTrackFactory.createScreenMediaTrack(appGroup:broadcastUploadExtension) on iOS, use createScreenMediaTrack(appGroup:broadcastUploadExtension:defaultVideoProfile) instead
• Deprecate ScreenMediaTrackFactory.createScreenMediaTrack(mediaSource) on macOS, use createScreenMediaTrack(mediaSource:defaultVideoProfile) instead
• Deprecate ScreenMediaCapturer.startCapture(atFps:outputDimensions) on iOS, use startCapture(atFps:) instead

• Adapt WebRTC output format on iOS

• Make it possible to participate in direct media calls
• New VideoContentMode.fit to fit the size of the video view by maintaining the original aspect ratio (could be used to support portrait video on direct media call)
• Send chat messages via WebRTC data channel when on direct media call
• Calculate secure check code on each send/receive of an SDP offer/answer, see MediaConnection.secureCheckCode
• Load conference themes, accessible via Conference.splashScreens property or splashScreen event
• New conference events:
  • splashScreen for local rendering of splash images and messages
  • peerDisconnected for restarting media connection during direct media call
  • refer for tranferring direct media call to transcoded call and back

• BREAKING: Use String instead of UUID for various types in PexipInfinityClient
