Release Notes for LiveSwitch Server v1.23

1.23.1.2634

Release date: April 1, 2025

Client SDK

Improvements
  • [LS1-2829] Added diagnostics related to JitterBuffer that can be enabled by setting EnableDiagnostics = true on a connection object.
  • [LS1-2838] [Android] Improved efficiency of Android Camera2Source.
  • [LS1-2840] [Android] Added threadId, tag, scope, and logContext to Android logs.
  • [LS1-2852] Updated clients to use MaxBundle bundling policy by default for SFU and MCU connections, retaining MaxCompatibility for Peer-to-peer connections. Now clients that open SFU and MCU connections will assume that the Media Server supports bundling and allocates fewer ICE candidates reducing application and relay server footprint. The server will remain backward compatible and connect with the legacy clients that do not support bundling.
Bug Fixes
  • [LS1-2801] [Android Example] Updated Android example to ensure that the resources are properly cleaned up when closing the screen-share session.
  • [LS1-2802] [Android] Fixed a bug preventing the Android version from being properly displayed in SDP messages.
  • [LS1-2828] [Client SDK] Optimized inbound RTP processing.
  • [LS1-2828] [Android Example] Updated example app to ensure it properly closes when force-closed via swiping.
  • [LS1-2828] [Android] Cleaned up Camera2Source shutdown logic to prevent ungraceful terminations.
  • [LS1-2828] [Android] Optimized Camera2Source Frame Buffer. Restricted older devices (Android 10 and older, under 3GB RAM, under 20% available memory) to use 2 frames for the camera buffer. Allowed modern devices (Android 14 and newer, above 6GB RAM and >30% available) to use 4 frames, except for hi-res cases (1080p and above). Retained 3 frames for all other cases.
  • [LS1-2878] [Media-Over-WebSockets] Fixed a bug where getting or setting a connections BundlePolicy on a WebSocket-based connection threw an exception.

Media Server

Improvements
  • [LS1-2855] Implemented a separate thread pool for TLS authentication to isolate resource usage from Media Server operations.
  • [LS1-2858] New deployment config values are logged during start-up: ThreadPoolStatsIntervalMs, DedicatedTlsThreadPoolSize, TlsAuthenticationTimeoutMs.
  • [LS1-2867] Added logging related to the ThreadPool statistics. Media Server also contains stats related to the dedicated TLS thread pool. Updated certain logs to indicate the amount of time spent for threads to be allocated.
  • [LS1-2889] Updated our default thread pool size from 100 to 300 to allow our servers to react to rapid changes in capacity demands. 
Bug Fixes
  • [LS1-2859] Fixed a bug where under certain conditions remote media could have been unnecessarily disabled when sent via clustering.

Gateway

Improvements
  • [LS1-2867] Added logging related to the ThreadPool statistics. Media Server also contains stats related to the dedicated TLS thread pool. Updated certain logs to indicate the amount of time spent for threads to be allocated.

1.23.0.1341

Release date: February 26, 2025

Client SDK

Bug Fixes
  • [LS1-2745] [ClientSDK] Introduced a new error code {{WebSocketMediaServerChannelVideoStreamCapacityReached}} indicating that the capacity was reached due to the number of video participants present in a channel. Error {{WebSocketMediaServerChannelClientCapacityReached}} was removed.
  • [LS1-2688] [MAUI] [Android] Fixed an issue that caused the Android app to crash due to a memory leak.
  • [LS1-2570] [LS1-2772] [Media-Over-WebSockets] Fixed a bug that, under certain conditions, prevented participants from rejoining a session.
  • [LS1-1792] [Media-Over-WebSockets] Fixed a bug when detecting if AudioEncoder is available in Safari Tech Preview which doesn’t completely support that feature yet.
  • [LS1-2775] [Media-Over-WebSockets] Fixed a bug that, under certain conditions, prevented user video from being displayed properly when rejoining a session.
  • [LS1-2743] [Media-Over-WebSockets] Fixed a bug that occured when rendering remote video when an invalid frame rate value is provided in the remote video encoding.
  • [LS1-2644] [Media-Over-WebSockets] Fixed an issue preventing participants from joining in the receive-only audio-only mode.
  • [LS1-2809] Addressed a recent regression in Chrome 133 where muting remote audio did not work.
Improvements
  • [LS1-2750] [Android] [Examples] - Updated Android Example to indicate the best practice of application backgrounding on Android 15.
  • [LS1-2771] [Examples] The .NET and Web examples have been updated to create an audio-only connection when creating a Media-Over-WebSockets with audio and video and receiving the error {{ErrorCode.WebSocketMediaServerChannelVideoStreamCapacityReached}}.
  • [LS1-2552] Removed support for deprecated TLS 1.0 and 1.1 for WebRTC TCP Relay connections, Media-Over-WebSockets, and WebSocket Signalling. Continuing to use TLS 1.2.
  • [LS1-2720] [ClientSDK] When publishing media via Media-Over-WebSockets, the default bitrate for audio encoding was lowered to 16kbps, and the default bitrate for video encoding was lowered to 256kbps.
  • [LS1-2726] [ClientSDK] When receiving Media-Over-WebSockets, comfort noise packets will not be sent through the WebSocket to save some bandwidth.
  • [LS1-2645] [LS1-2602] [Media-Over-WebSockets] Media handling for WebSocket connections has been moved to a Web Worker.
  • [LS1-2563] [MAUI] [iOS] Added support for Hybrid Globalization on iOS.
  • [LS1-2734] [Media-Over-WebSockets] Added round trip time tracking to the Media-Over-WebSockets transport layer and made available in Connection Stats.
  • [LS1-2735] [Media-Over-WebSockets] Enhanced WebSocket connection monitoring and cleanup by adding round-trip time tracking, improving error context in messages, and implementing a more robust connection shutdown sequence.
  • [LS1-2632] [Media-Over-WebSockets] When closing a connection fixed an issue where a Worker was not being terminated.
  • [LS1-2680] [Web] Added Screen Wake Lock API support in Web Example to prevent screen locking during active WebRTC connections, particularly benefiting mobile users in audio-only conferences where screen locks could previously interrupt ongoing calls.
  • [LS1-2724] Media-over-WebSockets now support unlimited audio-only connections while maintaining configurable video connection limits (defaulting to 10 video connections per client).

Media Server

Bug Fixes
  • [LS1-2552] Removed support for deprecated TLS 1.0 and 1.1 for WebRTC TCP Relay connections, Media-Over-WebSockets, and WebSocket Signalling. Continuing to use TLS 1.2.
  • [LS1-2686] Fixed a bug causing a null reference exception in the case where hex dump recording was enabled in a channel.
  • [LS1-2699] Fixed an SDP bundling issue where the Media Server incorrectly set the connection address to 0.0.0.0 in IPv6-only deployments.
Improvements
  • [LS1-2781] [WebSocket Media Server] Updated logging to ensure more contextual information is available.

Gateway

Breaking Changes
  • [LS1-2740] [Breaking Change] Fixed OData routing validation warnings that appear at Gateway startup by simplifying route names. Routes using 'FM.LiveSwitch.Model.SipInboundMappingConfig' pattern will be removed in version 1.24 - please migrate to use 'SipInboundMappingConfig' pattern. Old routes: api/v2.0/FM.LiveSwitch.Model.SipInboundMappingConfig - New routes: api/v2.0/SipInboundMappingConfig
Bug Fixes
  • [LS1-2552] Removed support for deprecated TLS 1.0 and 1.1 for WebRTC TCP Relay connections, Media-Over-WebSockets, and WebSocket Signalling. Continuing to use TLS 1.2.
  • [LS1-2737] Enhanced stability and performance by fixing memory leaks in Redis message handling, improving cancellation token management, and adding better logging for WebSocket connections.
  • [LS1-2729] Fixed misleading null reference error during PostgreSQL SSL handshake; users encountering the "Cannot validate remote certificate" error should verify their configuration includes "TrustedServerCertificateSha1Fingerprints" with valid certificate fingerprints.
Improvements
  • [LS1-2752] Optimized logging of webhook errors.
