[Live-devel] live-devel Digest, Vol 160, Issue 7

[Nir Haroosh]

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?

Thanks,
Nir
