Configure FFmpeg to save the recording at specified time intervals as separate output files
27 septembre 2023, par John DoeHow can I configure FFmpeg to save the recording into separate output files at specific time intervals, for example, every 25 seconds without interrupting the recording ? By default, FFmpeg saves the entire recorded video in a single output file, but I want to create separate output files for each 25-second segment.
What steps should I follow to achieve this ?


I tried python
multiprogramming
to run the recording and saving task simultanously but didn't work.

How about using the
@ffmpeg.on("progress")
event ?

Is it possible to save snapshots from multiple video streams using ffmpeg ?
14 novembre 2023, par Haydn MorrisI would like to periodically save a snapshot from a video stream using ffmpeg. This is is possible using the following command :


ffmpeg -i [source] -r 0.2 -f image2 ./image-%04d.jpeg


or the (rough) equivalent in ffmpge-python :


ffmpeg.input(source, **inputArgs)
 .filter("fps", fps=1 / 5, round="up")
 .output("./image-%04d.jpeg")



I would like to do this for N input streams simultaneously. So, I would be saving 1 frame every 5 seconds for each of the input streams. Is this possible using ffmpeg or ffmpeg-python ? I can't find any examples with multiple input streams.


Just for some more information : the sources are all rtsp streams and N can be between 10 and 60. I also would like to limit the number of files on disk at any one time (similar to G-streamer's max-files property) but this is less important.
