amazon-chime-sdk-js - npm Package Versions

[3.26.0] - 2024-10-07

Added

• Add interface for custom CDN paths for VideoFxProcessor

• Allow setting framerate on DefaultVideoTransformDevice

Removed

Changed

• Set starting send bitrate to 1000kbps to reduce time of low resolution at start of connection
• Add per-frame encoding time in video encoding CPU connection health policy
• Replace substr with substring
• Improve some log strings

Fixed

• Avoid breaking audio input when external devices are disconnected on iOS browsers when using Web Audio by suspending and resuming the audio context in that case.
• Fixed incoming audio loss calculation when server side network adaption and redundant audio features are running together.
• Prevent DataMessage callback errors from killing a meeting
• Do not store metrics for video send stream that no longer exists after reconnection
• Send audio downstream decoder loss and jitter buffer size to backend as intended, for internal debugging

[3.25.0] - 2024-09-10

Added

Removed

Changed

• Updated guides and doc-strings to recommend VideoPriorityBasedPolicy over VideoAdaptiveProbePolicy.

Fixed

• Include STUN packets in received packet reconnection check to mitigate edge cases when all attendee capabilities are 'None'
• Terminate audio RED worker before removing reference.

[3.24.0] - 2024-07-11

Added

Removed

Changed

Fixed

• Update uplink policy at codec degradation triggered by encoding health monitor.

[3.23.0] - 2024-05-14

Added

• Added DefaultDeviceController.suspendAudioContext and DefaultDeviceController.resumeAudioContext. Suspending and resuming the resusable audio context is preferable to stopping and recreating if an audio context eventually needs to be used again.

Removed

Changed

• Do not try to manually adjust SVC layers based off target resolution, as this may lead to an unnecessarily high minimum bitrate to subscribe to all remote videos. Instead rely on browser logic which drops any layers below around 135p.

Fixed

• Fixed rare race conditions with simulcast + server side network adaptation on third attendee join.
• Make redundant audio worker code generation script work on Windows
• Do not drop server side network adaptation pauses that happen immediately after SDP negotiation, by pre-emptively creating a tile immediately when applications subscribes to one, and attaching the video track later.

[3.22.0] - 2024-03-15

Added

• Add automatic codec degradation logic when CPU usage of software encoder is high or video encoding of encoder fails. This will only occur if setVideoCodecSendPreferences is being called by the application.
• Added groupId to VideoTileState for mapping metrics other then those from getObservableVideoMetrics when using server side network adaptation.
• Added support for Node version 22

Removed

Changed

• Avoid subscribes when simulcast is enabled but not currently sending, or when using server side network adaptation.
• Made server side network adaptation the default when creating VideoPriorityBasedPolicy.

Fixed

• Fixed reconnections not triggering audioVideoWasDemotedFromPrimaryMeeting.

[3.21.1] - 2024-03-28

Added

Removed

Changed

Fixed

• Fixed packets received check on Safari 17.3 and below

[3.21.0] - 2024-02-12

Added

Removed

Changed

• Simplified simulcast uplink policy to not unnecesarily try to compensate for uplink bandwidth estimation.
• Avoid unnecessary transceiver creation by using no-video policy for content share.

Fixed

• Fixed unnecessary cropping on some camera capturers when simulcast was enabled.

[3.20.0] - 2023-12-12

Added

• Add support for node 20 and drop support for node < 18.
• Add support for H.264 profiles besides Constrained Baseline Profile.
• Fix MeetingReadinessChecker demo by checking for audio kind

Removed

Changed

Fixed

• Fix reconnections when setting audio Attendee Capability to 'None' or 'Send' mid call. The connection health monitor will now look at all packets received on all candidate pairs instead of just audio received media packets.
• Setup passthrough streams for insertable streams case in the redundant audio worker so that passthrough streams do not get blocked on the main thread.
• Disable redundant audio for Chrome 106 and earlier to fix video decoder failure on old Chrome versions with redundant audio turned on.

[3.19.0] - 2023-09-20

Added

• Add support for high-definition WebRTC sessions with 1080p webcam video and 4K screen share. Developers can choose video encoding bitrates up to 2.5Mbps, frame rates up to 30fps, and the codec, including new options VP9, AV1, and scalable video coding (SVC).
• Update AWS SDK version to 3.477.0

Removed

Changed

• Revert: Improve reconnection behavior on signaling disconnection mid call or during join/subscribe. This was leading to unexpected AudioJoinedFromAnotherDevice events in certain edge conditions. It will be re-released in a later version.

Fixed

• Prevent video processing with filters from being throttled when an attendees meeting tab moves into the background.
• Do not allow redundant audio worker to enqueue any audio payloads larger than 1000 bytes to avoid permanently stopping the audio flow.
• Make uplink loss estimation more accurate so that redundant audio does not turn off prematurely.

[3.18.2] - 2023-10-09

Added

Removed

Changed

Fixed

• Save the redundant audio worker code during build time so that the worker code stays intact and is able to be loaded
