Efficient General‑Purpose Frame Extraction for AI Video Inference Services

The paper presents a unified, high‑performance frame‑extraction framework that dynamically selects CPU or GPU decoding, leverages multithreaded and CUDA‑accelerated pipelines, keeps frames in memory, and achieves up to ten‑fold latency reductions for diverse AI video‑inference tasks.
