I have an IP encoder with a built-in RTSP server, and the command "ffmpeg -rtsp_transport tcp -i rtsp://<ip_address>/live.sdp -c copy captured_file.mkv" works perfectly without any issues.
The problem is that the IP encoder could be rebooted anytime, which interrupts the ffmpeg capturing. I used a shell script to restart the ffmpeg capturing infinitely so nothing will be lost. The only issue is to fill the gap between two partial video files. I recorded the ffmpeg start timestamp every time it restarts, use it to generate an empty video block with the duration (2nd ffmpeg timestamp - 1st ffmpeg timestamp + 1st RTSP video duration), and use concat to merge 1st partial video + generated_gap + 2nd partial video. This method works, but it's not accurate because of the several seconds of initializing and buffering. Is there a way to get and store the timestamp when the first frame is being written? I googled some people saying to use pts/dts from RTCP, but couldn't find an exact way to archive it with ffmpeg. Please advise how to fill the gaps among partial RTSP streams precisely with ffmpeg.
