PROFILE
Shaun Loo
Worked on the ossrs/ffmpeg-webrtc repository to deliver performance-focused enhancements for video decoding, specifically targeting SAO processing in VVC and HEVC codecs. Developed a VVC SAO test suite within the checkasm framework, enabling direct performance comparisons between C and AVX2 assembly implementations and improving test coverage. Refactored HEVC SAO filtering by removing code duplication, introducing macros for common filter configurations, and streamlining x86 assembly code to enhance maintainability and performance. Leveraged skills in Assembly Language, SIMD, and low-level optimization to reduce maintenance overhead and clarify optimization paths, ensuring the codebase is better prepared for deployment and ongoing development.
