How to extract audio with youtube-dl on Windows

I want to extract audio from a video downloaded with youtube-dl on Windows. I got youtube-dl working, but am unable to extract the audio. This problem is caused due to not having the correct audio codes installed.

When I try to extract audio it tells me the following:

WARNING: unable to obtain file audio codes with ffprobe

The youtube-dl manual says:

-x -extract-audio    convert video files to audio-only files (requires ffmpeg or avconv and ffprobe or avprobe)

How do I install ffprobe or ffmpeg? Do I install this on Windows, or do I install this as a Python extension?

My OS is Windows 7.

Answer #1:

ffmpeg is not a Python module. Take a look at the code of youtube-dl in the FFmpegExtractAudioPP class.

It uses this call to figure out if the executable exists or not. It checks in your current path:

subprocess.Popen([exe, '-version'], stdout=subprocess.PIPE, stderr=subprocess.PIPE).communicate()

You'll need to download the Windows builds of ffmpeg and put them in your current path, probably making sure that they do not have .exe at the end of their names.

Answer #2:

A quick fix for Windows users:

Download the ffmpeg package from http://ffmpeg.zeranoe.com/builds/, unzip it, copy ALL the contents of the Bin directory to the directory where youtube-dl.exe is located.
Using DOS navigate to the directory where youtube-dl is located and run using the command:
```
youtube-dl --extract-audio --audio-format mp3
```

Answer #3:

EDIT

Future users may want to download the latest build from ffmpeg.org

My rep doesn't allow me to add a comment so I will put in here.

As per Sep 18, 2020 http://ffmpeg.zeranoe.com/builds/ is closed, but still accessible via Web Archive. The complete downloads are still available from here:

http://web.archive.org/web/20200918193047/https://ffmpeg.zeranoe.com/builds/

I have made the following files/versions available for Windows users from my Google Drive but please don't take these as granted, and scan for malware or viruses as always:

ffmpeg-4.2.2-win32-static.zip
ffmpeg-4.2.2-win64-static.zip
ffmpeg-4.2.3-win32-static.zip
ffmpeg-4.2.3-win64-static.zip
ffmpeg-4.3-win32-static.zip
ffmpeg-4.3-win64-static.zip
ffmpeg-4.3.1-win32-static.zip
ffmpeg-4.3.1-win64-static.zip

Once downloaded, I extracted the latest build (4.3.1) on Windows 10 and copied all the .exe (ffmpeg, ffplay, ffprobe) to the same directory as youtube-dl, and then run:

youtube-dl -x --audio-format mp3 https://www.youtube.com/watch?v=...

Answer #4:

You can easily get win-ffmpeg using chocolatey

and if you still can’t get youtube-dl and ffmpeg to work together,

maybe you can do it in two steps:

Get mp4 or avi : youtube-dl url
Extract audio

ffmpeg -i input.mp4 -vn -codec copy out.mp3
