Overview

Minor changes

• API addition to data tracks: adds tryPush for pointer/size, to avoid a copy needed into std::vector when source data was in this format
• Minor breaking change: this SDK no longer builds or publishes a LiveKit Docker image. Per available metrics it didn't appear that these images were being pulled, but please consider using an older release's Docker file and integrate it to your build, or raise an issue if this is blocking.

• Use robotics team CODEOWNERS by @alan-george-lk in #241

Full Changelog: v1.5.0...v1.6.0

Overview

Minor changes

• Brings in livekit-ffi v0.12.72
• Adds data-track schema metadata, including well-known and custom schema/frame encodings
• Adds DataTrackPublishOptions and exposes schema and frame-encoding metadata through DataTrackInfo
• Adds LocalParticipant::defineSchema() and getSchema() for storing and retrieving schema definitions

Bug Fixes

• AudioFrame now rejects non-positive channel and sample counts, preventing potential division-by-zero and integer-overflow issues

Server requirements

Schema definitions use participant data blobs and require LiveKit Server v1.13.3 or newer.

For a local or self-hosted server, enable participant data blobs:

LIVEKIT_CONFIG="enable_participant_data_blob: true" livekit-server

Full Changelog: v1.4.0...v1.5.0

Overview

Minor changes

• Brings in livekit-ffi v0.12.71 release

• Examples submodule now references new PlatformAudio, TokenSource, and video frame metadata examples.
