Worked on stabilizing FFmpeg integration within the microsoft/vcpkg repository, focusing on improving build reliability and cross-platform compatibility. Addressed a CMake warning in the FFmpeg port configuration, updated the port version, and refined ALSA conditional logic to ensure consistent builds across Linux, Windows, and macOS. Leveraged expertise in CMake, cross-platform development, and package management to deliver a targeted bug fix, with all changes consolidated into a single, audit-ready commit for traceability. Utilized both CMake and JSON to manage configuration and versioning, contributing to the ongoing maintenance and security of the FFmpeg port without introducing new features during this period.
