When attempting to process a video, the application requests cuda:0, but immediately triggers a fallback to CPU inference because no CUDA inference provider is available in the bundled environment (CUDA device 0 was requested but no CUDA inference provider is available; using CPU inference).
Even though an NVIDIA GPU is present and hardware encoder (h264_nvenc) is detected, all ONNX-based tasks (like RapidOCR) run strictly on the CPU, causing significantly slower processing times.
