Worked on the ossrs/ffmpeg-webrtc repository to enhance platform stability and cross-architecture support, focusing on LoongArch LSX and Loong64 systems. Addressed a decoding issue in HEVC motion compensation by correcting loop counter initialization and residual calculations, which improved decoding correctness and test reliability on LoongArch LSX. Additionally, updated the build configuration to recognize Loong64 in the configure script, enabling reliable builds and deployments on Loongson-based environments. These changes were implemented using C, Assembly (LSX), and Shell scripting, emphasizing low-level optimization and build system configuration to ensure robust video codec performance and streamlined cross-platform development workflows.
