Worked on enhancing the Zsh completion script for ffmpeg in the zsh-users/zsh repository, focusing on improving reliability and maintainability. Replaced the previous fragile parsing logic with a robust awk-based extraction method, leveraging shell scripting and CLI tooling expertise. Migrated the completion system to use a static, comprehensive list of standard ffmpeg arguments, ensuring consistent and predictable behavior across different environments. Addressed compatibility issues with modern ffmpeg versions by resolving patch header problems and incorporating forward-looking fixes. Maintained a clear and auditable commit history, supporting future development and easier maintenance of the completion script within the broader Zsh ecosystem.
