During September 2025, My4ng rewrote the NLMeans Vulkan filter in the FFmpeg/FFmpeg repository, focusing on both performance and visual quality improvements. The work involved restructuring the weights pass into separate vertical and horizontal components and removing the atomic float requirement, which increased parallelism and reduced processing overhead. My4ng addressed image loading and buffer handling issues to improve stability and correctness, while also implementing memory bandwidth optimizations to minimize GPU-CPU data transfer. Utilizing C and GLSL with expertise in GPU computing and Vulkan, My4ng delivered a more efficient denoising filter, enhancing both speed and output quality for media processing pipelines.
