  • ffmpeg http slower than downloading first

    9 août 2017, par Krylic

    When trying to get a clip of a video from a remote source
    Input source :

    ffprobe version 3.3.2-static http://johnvansickle.com/ffmpeg/  Copyright (c) 2007-2017 the FFmpeg developers
    Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'http://website.com/video.mp4':

    Current command :
    ffmpeg version 3.3.2-static
    ffmpeg.linux -threads 2 -y -ss 3273 -i "http://website.com/video.mp4" -an -movflags +faststart -preset veryfast -codec copy /outputfolder/trimmed_video.mp4
    This 5m35.102s to create a 45mb 2min file.

    If I download the file using wget it takes 28s and using ffmpeg only takes 0.243s

    If I add -vn OR -an to the output portion of the command it completes the trim in about 2.101s. Meaning it’s faster to download the two stream and merge them myself.

    Can anyone explain this behaviour and why my first command takes so long when on a lot of other video files it’s very fast ?
