This paper proposes a simple yet effective approach to measure the e2e latency in the live video streaming pipeline, from when the signal is generated in the production studios until it is played on the client device. The method is based on user-centric behavior by looking at the time the content is produced in the source context and comparing it with the current clock time at the playback device. Given a clock timestamp introduced in the signal at the production stage, we rely on an intelligent streaming latency measurement agent that, first, detects with YOLO that mark at the playout device, then use an OCR to convert the bitmap text in the clock to a string text, and finally, compares it with the real-time clock in the machine, providing real-time end to end streaming latency. Our method, even simple, allows us to measure the latency on any playout device, as it does not rely on any in-band signaling but a human-centric behavior simulated by an intelligent measurement agent.
