During September 2025, Joju Yung developed the ONVIF Mirror Attribute for Horizontal Video Flip within the onvif/specs repository, focusing on enhancing interoperability and control for video streams. He defined and integrated a new schema attribute in XML, enabling horizontal flipping of video feeds and ensuring downstream clients could implement the feature consistently. Joju also updated related documentation, clarifying how the new mirror attribute interacts with existing rotation and PTControlDirection settings. His work demonstrated careful schema definition and precise documentation updates, addressing a specific need for flexible video stream manipulation. The contribution was focused, technically sound, and well-aligned with ONVIF standards.
