  • FFMPEG command works on Mac but not on Windows [duplicate]

    24 décembre 2019, par Arthur

    This question is an exact duplicate of :

    Hi I’m working on a project which needs to create animations by playing 2000 charts in 50 fps using FFMPEG, the command is :

    ffmpeg -y -framerate 50 -i img-%04d.png -vb 40M -vcodec h264 esez.mp4

    charts are located in the same folder with name as img-0001.png img-2000.png

    It worked well on my Mac. On Windows, the command can run and generate a mp4 file. But the animation is just black screen on Windows media player. I also tried open with VLC, it has some image, but not proper at all.

    log from Windows CMD :

  • Creating mosaic stack 25 videos ffmpeg windows cmd

    26 décembre 2019, par KIngking431

    Hi I am trying to make a video mosaic of 25 videos in ffmpeg

    I used Jim B’s perl script to make this script, previous on my mac it worked.
    But I can’t get it to work on my windows computer in command prompt.
    I think it executes each line of code individually

    Is there something fundamental about commandprompt I am missing ?

  • ffmpeg function/alias in .bash_aliases [duplicate]

    29 décembre 2019, par unammusic

    This question already has an answer here :

    I’m trying to build a function in my aliases to avoid typing the whole ffmpeg command everytime for a simple video cut like this :

    ffmpeg -ss 00:00:00 -t 00:00:10 -i video.mp4 -vcodec copy -acodec copy video_cut.mp4

    So I came up with this idea :

    function ffmpeg-cut () {
    
  ffmpeg -ss '$1' -t '$2' -i '$3' -vcodec copy -acodec copy '$3'_cut.mp4
    
}

    or as a one liner :

    alias ffmpeg-cut='ffmpeg -ss '$1' -t '$2' -i '$3' -vcodec copy -acodec copy '$3'_cut.mp4'

    I guess it’s some kind of syntax error but I can’t figure out. Anyone any idea ? This is my output when I try :
