  • How to show segment lengths of hls file with ffmpeg

    30 mai 2017, par endorphins

    I’m trying to use ffmpeg to retrieve the segment duration of every segment for every stream of an HLS file. It looks like I can do this if I know all of the names of the individual files in advance and call ffprobe on each one. This seems really tedious and I won’t always know the names of all of the individual files, only the main .m3u8. Is there any way I can get all of this information with just one ffmpeg command ?

    Additionally, is the duration retrieved by ffprobe on a .aac file accurate ? I get the message that it’s "Estimating duration from bitrate, this may be inaccurate".

  • With ffmpeg's image to movie feature, is it possible to pass in frames over a period of time versus all at once ?

    2 novembre 2013, par Zack Yoshyaro

    For the purpose of making a time lapse recording of desktop activity, it is possible so "stream" the frame list to ffmpeg over time, rather than all at once in the beginning.

    Currently, it is a two step process.

    1. save individual snapshots to disc

      im = ImageGrab.grab()
      im.save("frame_%s.jpg" % count, 'jpg')

    2. compile those snapshots with ffmpeg via

      ffmpeg -r 1 -pattern_type glob -i '*.jpg' -c:v libx264 out.mp4

    It would be nice if there were a way to merge the two steps so that I'm not flooding my hard drive with thousands of individual snapshots. Is it possible to do this ?
