During December 2025, Miyauchi contributed to the pion/webrtc repository by developing Direct PTS mode, a feature that allows RTP timestamps to be used directly as PTS values, thereby improving precision in video streaming workflows. Miyauchi implemented this by introducing the WithDirectPTS option and updating the IVFWriter component to support both the new and legacy behaviors, ensuring backward compatibility for existing deployments. The work involved careful adjustments to tests to validate both modes, reflecting a thoughtful approach to minimizing migration risk. Miyauchi’s contributions leveraged Go, streaming protocols, and video processing expertise, demonstrating depth in protocol-level feature delivery and maintainability.
