Thanks for your answer. The detection part is already done and works.
The focus of my question is how to implement a pre-event recording of the RTSP into mp4 file. Pre-event means that I need to capture video which starts from 10 seconds back (before) the time of requesting the recording. For example, if I request a recording on time 12:20:40 (hh:mm:ss), I need the recorded video in the mp4 to start on 12:20:30 (10 seconds before) and end on 12:20:55 (15 seconds after). Can you explain how to do it?
