PROFILE
Dash Santosh
Over a two-month period, contributed to GPU-accelerated video processing in the ossrs/ffmpeg-webrtc repository by developing a Direct3D 11-based FFmpeg video filter that offloads scaling and pixel format conversion to the GPU, reducing CPU overhead and latency for live WebRTC workloads. In the FFmpeg/FFmpeg repository, implemented ARM NEON assembly optimizations for yuv2nv12cx conversion, achieving up to 8.68x performance improvement on aarch64 platforms. Work also included code formatting and refactoring to maintain readability and future scalability. Demonstrated expertise in C, Assembly, and low-level optimization, focusing on efficient, maintainable solutions for real-time video processing pipelines across architectures.
