In April 2025, Alessandro Manelli enhanced the pion/webrtc repository by implementing default H.265 codec support within the media engine, focusing on codec interoperability and readiness for modern streaming requirements. He configured both H.265 and RTX codecs in the RegisterDefaultCodecs function, ensuring H.265 was readily available for media streams and enabling hardware acceleration across media paths. Working primarily in Go and applying his expertise in codec implementation and media engineering, Alessandro delivered this feature as a focused, single-commit change. This approach facilitated faster code review and safer rollout, addressing compatibility and performance needs for contemporary media streaming workflows.
