Worked on improving the stability of the H.265 decoding pipeline in the intel/vpl-gpu-rt repository by addressing a memory management issue that could cause slice leaks when frame decoding failed. Focused on low-level programming in C++ to ensure that slice objects were properly stored and released, reducing memory pressure and preventing leaks in error scenarios. Validated the fix using appverifier to confirm reliability improvements. This work enhanced the robustness of video decoding, particularly under failure conditions, and demonstrated careful attention to memory lifecycle management, targeted debugging, and effective use of git for traceability throughout the development and validation process.
