avcodec/lpc : Avoid floating point division by 0
28 mai 2021, par Michael Niedermayer -
Pydub The system can not find the file specified
11 janvier 2021, par MadarSo 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

using for loop in powershell with ffmpeg to create thumbnails
29 septembre 2020, par blueI 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'
 
}
