During July 2025, Kman developed WHIP-WHEP audio track support for the pion/webrtc repository, enabling seamless end-to-end audio transmission and reception in both WHIP and WHEP demo modes. Working primarily in Go and JavaScript, Kman focused on stabilizing the demo surface by implementing robust CORS preflight request handling and comprehensive End-Of-File management to prevent panics during streaming. The work also included targeted refinements to improve maintainability and clarity of the WHIP-WHEP example code, with enhanced inline documentation. This feature-driven contribution addressed interoperability challenges in media streaming and demonstrated a thoughtful, detail-oriented approach to WebRTC application engineering.
