PROFILE
Yuanhecai
Yuanhe Cai focused on low-level performance and compatibility engineering across open-source multimedia and SIMD libraries. In ossrs/ffmpeg-webrtc, Yuanhe stabilized Loongarch builds by updating Loongarch-specific assembly in C and C++ to match evolving core functions, which improved test reliability and reduced CI failures. Later, in the libsdl-org/highway repository, Yuanhe enabled Loongson LSX and LASX SIMD acceleration by updating build systems and adding LoongArch-specific headers, while also expanding automated CI coverage for LoongArch64 using CMake and cross-compilation. This work enhanced performance validation and future optimization readiness, demonstrating depth in assembly language, build systems, and cross-architecture testing.
