  • How to convert first few seconds of a video to multiple output formats using ffmpeg

    5 juin 2012, par Hadi

    I want to convert first few seconds (say 5 seconds) of a video to multiple output formats using ffmpeg.

    when I Use this syntax to convert whole video, everything goes ok :
    (to be simple, i left all options to be default)

    ffmpeg -i input.flv output1.mp4 output2.avi

    but when trying for just first 5 seconds using this syntax :

    ffmpeg -t 5 -i input.flv output1.mp4 output2.avi

    first output file (i.e ouptput1.mp4) is ok and it is 5 seconds length, but the second (and next outputs, if present) has a size of original file.

    this is what ffmpeg prints out on the screen.

    D:\ffmpeg\bin>ffmpeg -t 5 -i input.flv output1.mp4 output2.avi

    How is the correct syntax to get all output files same size ?

    isn't this a bug with ffmpeg ? (note last lines of conversion progress, which all timestamps look same)

    thanks in advance.
