During March 2026, work focused on enhancing the livekit/server-sdk-go repository by implementing support for the Abs-Capture-Time RTP header extension within LocalTrack. This involved translating the header extension before writing to the peer connection and registering it in the transport layer for both audio and video streams, ensuring end-to-end compatibility with extended capture-time metadata. The update improved synchronization and diagnostics across real-time streaming sessions, aligning with ongoing ACT support improvements. The engineering effort leveraged Go for backend development and integrated WebRTC protocols to address real-time communication requirements, demonstrating depth in protocol-level feature implementation and attention to interoperability within streaming infrastructure.
