During the month, work focused on enhancing memory safety within the intel/vpl-gpu-rt repository by addressing a critical issue in the secure encoding flow. Using C++ and leveraging expertise in memory management and software engineering, the developer refactored the mfxEncodeParamMap structure to replace raw pointers with std::reference_wrapper. This targeted change eliminated the risk of dangling pointers, ensuring correct lifetime tracking for external pointers without altering existing APIs. The solution stabilized the encoding path and maintained compatibility, with all modifications clearly documented and traceable through a dedicated commit. The work demonstrated careful attention to robust, maintainable code and precise problem resolution.
