PROFILE

Ningyuan Li

Worked on LizardByte/Sunshine and xbmc/xbmc, delivering features and fixes focused on audio and video streaming reliability. Developed dynamic HEVC encoding level auto-selection for 4K and below, optimizing video encoding performance and hardware compatibility using C++ and configuration management techniques. Addressed critical Wayland backend issues in xbmc/xbmc by refactoring destructor logic to prevent use-after-free and double-destruction, improving system stability and memory management. Added continuous audio streaming support in LizardByte/Sunshine by introducing a configuration flag and updating audio capture logic, enabling real-time ingestion scenarios. Demonstrated disciplined, incremental delivery and cross-platform development across both repositories.
