Worked on performance and compatibility improvements for open source multimedia and SIMD libraries, focusing on Loongarch and Loongson architectures. In ossrs/ffmpeg-webrtc, updated Loongarch-specific assembly in C and C++ to align with evolving core functions, resolving a test failure and improving CI reliability. Later, contributed to the libsdl-org/highway repository by enabling LSX and LASX SIMD acceleration for Loongson hardware, updating build systems and adding LoongArch-specific headers. Expanded automated testing by integrating LoongArch64 cross-compilation into CI workflows using CMake and Shell scripting. These efforts enhanced cross-architecture support, streamlined validation, and improved performance for targeted hardware platforms.
