  • using for loop in powershell with ffmpeg to create thumbnails

    29 septembre 2020, par blue

    I have this basic for loop combined with ffmpeg that creates thumbnails for each video.

    


    Could anyone help me figure out why it doesn't work ? I don't really know much about powsershell.

    


    If i were to use a regular array it works but when i use a pre-sized array it does not.
EDIT :
somehow figured it out, i should have included the extention'.png' in the array instead of adding at the end of the for loop.i also didn't define a size for the array.

    


    $files = @(Get-ChildItem -Path 'D:\other stuff\ffmpeg test\*.mp4')
$filetext = @()
$test = 'd.png'

  
 for ($i=0; $i -lt $files.length; $i++){ 
 $filetext += (Get-Item $files[$i]).Basename + '.png'
 ffmpeg -i $files[$i] -ss 00:00:01  -vframes 1 $filetext[$i] 

}


    


    PS D:\other stuff\ffmpeg test> $files = @(Get-ChildItem -Path 'D:\other stuff\ffmpeg test\*.mp4')
$filetext = [Object[]]::new(100)


for ($i=0; $i -lt $files.length; $i++) {
  $filetext[$i] = % {$files[$i].BaseName}
  ffmpeg -i $files[$i] -ss 00:00:01  -vframes 1 $filetext[$i]'.png'
    
}

  • Pydub The system can not find the file specified

    11 janvier 2021, par Madar

    So here is my code :

    


    from pydub import AudioSegment
sound1 = AudioSegment.from_mp3("sound_0.mp3")
sound2 = AudioSegment.from_mp3("sound_1.mp3")

sound = sound1 + sound2
sound.export("test.mp3",format="mp3")


    


    Problem :
I got the error message : WindowsError : [Error 2] The system can not find the file specified

    


    System configuration
Python version : 3.8
Pydub version : I just installed it
ffmpeg or avlib ? : ffmpeg
ffmpeg/avlib version : 2020-12-15-git-32586a42da-full_build-www.gyan.dev

    


    What did I try ?
So, I found some things to do on a Stackoverflow subject,
I tried to add this

    


    pydub.AudioSegment.ffmpeg = "way//to//ffmpeg.exe"


    


    But it doesn't worked, then this

    


    AudioSegment.converter = "way//to//ffmpeg.exe"


    


    Still doesn't work, so, because I'm on spyder with anaconda, I tried this on the anaconda prompt

    


    conda install -c conda-forge ffmpeg


    


    I even tried to put ffmpeg.exe,ffplay.exe in the current working directory but still doesn't worked..

    


    So I'm desperately here for some help, thanks in advance
