Worked on enhancing build and video encoding systems across two open source repositories. In videolan/meson, delivered a Vulkan SDK compatibility improvement by introducing a VK_SDK_PATH fallback, allowing the build system to support older Vulkan SDK environments and simplifying cross-system setup. This change streamlined dependency management and improved onboarding for developers using C and Python. Later, in ossrs/ffmpeg-webrtc, addressed a critical bug in the Vulkan H.265 encoder by correcting capability flag reporting, ensuring accurate interoperability and performance in WebRTC pipelines. The work demonstrated a focus on robust build systems, C programming, and effective management of video encoding dependencies.
