How to Buffer RTSP Stream in ACAP App to Sync Overlays with Frame PTS

[HyobinPark-AIVN]

Problem:
In a real‐time video processing system, if “data generation (frame capture)” and “result display (overlay rendering)” use different reference timestamps, the overlayed results will always lag behind the live video by the processing latency.

Question:
Is it possible—in an Axis ACAP application—to deliberately introduce a delay into the camera’s video stream so that the overlay and the video remain in sync?
