Worked on the FFmpeg/FFmpeg repository to address a targeted memory leak in the AVIOContext cleanup process, focusing on improving memory safety and stability within the I/O component. Using C programming and expertise in memory management, implemented a patch that frees protocol whitelist and blacklist resources in avio_context_free by leveraging av_freep, thereby reducing the risk of leaks during resource cleanup. The solution was well-scoped, adhering to FFmpeg’s coding standards and included clear documentation updates. This work enhanced the maintainability of the library’s codebase and laid the foundation for more robust memory hygiene in future media processing workflows.
