so basically I want to convert song what I downloaded from youtube in webm and convert to into mp3
when I wanted export song just with song.export("neco.mp3")
it didn’t work too
I have in workfolder ffmpeg.exe and ffprobe.exe
here is the code
from pydub import AudioSegment song = AudioSegment.from_file(downloaded.webm,"webm") print("Loaded") song.export("neco.mp3", format="mp3", bitrate="320k") print("Converted and saved")
here is the output of the console

I think it is something with codec but I have no idea what to do

Answer
Had a similar problem with ffmpeg.exe (4.3.1),
but everything works fine with ffmpeg-20200802-b48397e-win64-static,
since mp3_mf is not used in the standard container there
(WAV/MP3 in your problem, AVI in my problem).
So if you can’t switch to a different ffmpeg version,
you should force it to use libmp3lame, not just mp3
and the use of (System?)-codec mp3_mf :
So don’t use: -f mp3
Instead use (or add): -c:a libmp3lame
