During January 2026, Neoyoda42 developed an HDR Video Stream Handling Optimization for the Sonarr/Sonarr repository, focusing on improving back end performance for HDR content. The work involved refactoring the stream selection logic in C# to analyze available video streams and ensure the correct stream was chosen, which reduced unnecessary data transfer and improved playback efficiency. By targeting the underlying stream analysis and optimizing how the video stream index is determined, Neoyoda42 enabled smoother HDR playback and lower bandwidth usage. This feature demonstrated depth in C# back end development, addressing both performance and resource utilization for high-quality video streaming scenarios.
