Make sure you have the last version for youtube-dl
<code>sudo youtube-dl -U</code>
after that you can solve this problem by installing the missing <code>ffmpeg</code> on ubuntu and debian:
<code>sudo apt-get install ffmpeg</code>
and macOS use the command:
<code>brew install ffmpeg</code>

I know the user asked this for Linux, but I had this issue in Windows (10 64bits) and found little information, so this is how I solved it:

<ul>
<li>Download <a href="http://builds.libav.org/windows/release-gpl/" rel="noreferrer">LIBAV</a>, I used libav-11.3-win64.7z. Just copy "avprobe.exe" and all DLLs from "/win64/usr/bin" to where "youtube-dl.exe" is.</li>
</ul>

In case LIBAV does not help, try with <a href="http://ffmpeg.zeranoe.com/builds/" rel="noreferrer">FFMPEG</a>, copying the contents of the "bin" folder to where "youtube-dl.exe" is. That did not help me, but others said it did, so it may worth a try.

Hope this helps someone having the issue in Windows.

There is some confusion when using <code>pip install</code> in Windows. The instructions talk about a specific folder which has <code>youtube-dl.exe</code>. There is no such folder if you use <code>pip install</code>. 

The solution is to: 

<ul>
<li>Download one of the builds from <a href="https://ffmpeg.zeranoe.com/" rel="noreferrer">https://ffmpeg.zeranoe.com/</a></li>
<li>Extract the zip contents</li>
<li>Place the contents of the <code>bin</code> folder (there are three exe files) in any folder which is a <code>path</code> in Windows. I personally use Ananconda, so I placed them in <code>/Anaconda/Scripts</code>, but you could place it in any folder and add that folder to the path.</li>

2- go to <a href="https://evermeet.cx/ffmpeg/" rel="nofollow noreferrer">https://evermeet.cx/ffmpeg/</a> and download <code>ffmpeg</code> and <code>ffprobe</code>
3- run <code>which youtube-dl</code> on Terminal to get the path, where youtube-dl is installed.
you should get something like this : <code>/Library/Frameworks/Python.framework/Versions/3.9/bin/</code>
4- copy the 2 file you downloaded <code>ffmpeg</code> and <code>ffprobe</code> to the <code>bin</code> folder of your path from step 3.
that's it. you shouldn't get this error again.
