When performance matters: running a real-time computer vision pipeline

A real pipeline claims a hard 300ms end to end and shows what actually meets that bar: OpenCV for capture and preprocessing, YOLO models for player and ball, ONVIF commands to a PTZ camera, and a local server for bandwidth and latency. Debugging reveals a multiprocess Queue bottleneck that accumulates frames into 8 second delays and is replaced with ZeroMQ publisher/subscriber, bringing runtimes down toward ~1 second in practice.
