PROFILE
Shiyou Yin
Yin Shiyou contributed to the ossrs/ffmpeg-webrtc repository by enhancing platform stability and cross-architecture support over a two-month period. He focused on low-level optimization and build system configuration, using C, Assembly (LSX), and Shell scripting. His work addressed HEVC decoding correctness on LoongArch LSX by fixing loop counter initialization and residual calculations, which improved motion compensation reliability and resolved architecture-specific test failures. Additionally, he expanded build configuration to support Loong64, updating the configure script to recognize new hardware and prevent misconfigurations. These targeted bug fixes demonstrated careful risk management and a deep understanding of embedded systems and video codec optimization.
