I have a problem with Pydub module running in Windows and Linux. When I try open a mp3 file thus:

from pydub import AudioSegment
sound = AudioSegment.from_mp3("test.mp3")

Console show me the next message:

WindowsError: [Error 2] The system can not find the file specified

But...I have the file (test.mp3) in the same folder that the script, the name is correct.

Why I have this problem? (In Linux, have the same error)

  • It would be convenient if you could translate the error to English language and edit the question. – ρss Mar 09 '14 at 15:59
  • `test.mp3` has to be in the directory where you run the script from (`import os; print(os.getcwd())` to show it), not from the directory where the script is. – Valentin Lorentz Mar 09 '14 at 15:59
  • Error translated (pss). I run the script in the same folder where the sound and script are...and i Have the same error – gasgen Mar 09 '14 at 16:02
  • Provide details please. What is the python version? Have you installed ffmpeg. – ρss Mar 09 '14 at 16:26

Make sure that you have ffmpeg http://www.ffmpeg.org/ installed. You can get help from this official page.

Other thing that I can think of is that ffmpeg is installed and is in your path but not in the path of the process using pydub.

If this is the reason for the error, then you can set the absolute path to ffmpeg directly like shown below:

import pydub
pydub.AudioSegment.ffmpeg = "/absolute/path/to/ffmpeg"
sound = AudioSegment.from_mp3("test.mp3")

Give this a try.

  • Thanks pss!, the problem was the absolute path of ffmpeg in the script! – gasgen Mar 09 '14 at 18:06

    `AudioSegment.ffmpeg` doesn't work on newer versions, it seems to be `AudioSegment.converter` as in the other answer. – Basj Dec 04 '18 at 23:42

In jupyter notebook this error could persist since the error is with anaconda environment. You can solve this by installing ffmpeg from conda-forge

Got to anaconda prompt and type:

conda install -c conda-forge ffmpeg

In newer versions of , you can specify the absolute path to your executable by setting the class attribute converter, e.g.:

from pydub import AudioSegment
AudioSegment.converter = "/usr/local/bin/ffmpeg"

In older versions the class attribute used to be ffmpeg, which is deprecated now.

The other way is put ffmpeg.exe,ffplay.exe in the current working directory

    Thank you so much. It took me 3 days to debug this trivial buggy/error. I was about to give up on pydub. Thanks for your help. – JIGAR JOSHI Jun 23 '20 at 09:06

Solution for MacOs and compiled Python

Maybe this solution is a bit hacky and not the best way, but it actually works for me on MacOs where I had the same problem. It solves the problem if the python script cannot access the system $PATH variable. I had to do it this way because I run my python code as a compiled binary from a java program which means for some reasons that the system $PATH variable set on my MacOs system cannot be accessed by the compiled python code.

Add this to your python code:

import os
os.environ["PATH"] += os.pathsep + '/usr/local/bin'

'/usr/local/bin' is the default for MacOs - please change it if you installed ffmpeg in a different location.

I got the idea from an answer to that question: how do I modify the system path variable in python script?

you need to this:

1- Download and extract libav from Windows binaries provided here. (http://builds.libav.org/windows/)

2- Add the libav /bin folder to your PATH envvar

Install ffmpeg then add ffmpeg.exe to your environment path, it works fine after that.
