Worked on stabilizing the Vulkan-based FFv1 encoding path in the ossrs/ffmpeg-webrtc repository by addressing a critical array overflow issue. Using C and leveraging low-level programming skills, implemented descriptor-set array bounds protection to prevent out-of-bounds access during video encoding. This targeted fix involved adding a placeholder to the descriptor set array, directly improving the reliability and correctness of the FFv1 Vulkan encoder. The solution reduced the risk of runtime crashes in production environments and contributed to the maintainability of the codebase. Focused on delivering a low-risk, high-impact bug fix that enhanced the stability of the video encoding pipeline.
