In April 2025, Alessandro Manelli enhanced the pion/webrtc repository by implementing default H.265 codec support within the media engine. He focused on codec interoperability and media engine readiness, configuring both H.265 and RTX codecs in the RegisterDefaultCodecs function to streamline streaming with modern codecs and enable hardware acceleration across media paths. Using Go and leveraging his expertise in codec implementation and media engineering, Alessandro delivered these changes in a focused, single-commit approach, which facilitated faster code review and safer rollout. His work improved compatibility and performance for media streams, addressing the need for modern codec support in real-time applications.
