• FFmpeg : Split video and preserve input source time

  27 janvier 2015, par Arun

  I’m trying to split a large video into chunks with the below command based.

  ffmpeg -i input.avi -vcodec copy -an -ss 0 -t 60 output-1.avi
  
  ffmpeg -i input.avi -vcodec copy -an -ss 60 -t 60 output-2.avi

  and so on.

  I need to preserve the frame timestamps in the output video chunks. That is, if the video is 10 minutes long and if each video chunk is 5 min, the second chunk’s starting timestamp should be 05:00 and not 00:00.

  As mentioned in the FFMpeg documentation, I tried the -copyts option with -start_at_zero without any luck.

  At present, I have a work around to pass the offset (05:00) along with the file name externally so that the frame timestamp can still be tracked. But this is not the ideal solution, I believe.
