Worked on enhancing the robustness of the AV1 video decoder within the intel/media-driver repository, focusing on improving stability when handling corrupted or unusual reference frame data. Addressed two critical bugs by implementing defensive checks and centralized error handling in the C++ decoding path, ensuring the decoder gracefully manages invalid reference frame indices such as 0xFF. Introduced logic to track valid reference picture indices, reducing crashes and undefined behavior during AV1 stream playback. These targeted software engineering improvements increased playback reliability, reduced user-reported issues, and aligned the codebase with broader resilience and quality goals, supporting future test coverage and maintainability.
