Worked on the contentauth/c2pa-rs repository to enhance the robustness of BMFF meta box parsing, specifically targeting Apple devices where the FullBox header may be omitted. Addressed a critical edge case by implementing a detection heuristic that inspects the meta box header and checks for the required first child, aligning the parsing logic with established behaviors in FFmpeg and Bento4. This Rust-based backend development improved reliability in C2PA manifest extraction, reducing errors such as asset bound overflows on iOS and macOS. Additionally, code quality was improved by resolving clippy and formatting issues, contributing to better maintainability and cross-tool compatibility.
