ERROR: audio conversion failed: Unknown encoder 'libmp3lame'

When extracting the audio I get this error message saying that libmp3lame is unknown.

I've done everything, from updating lame to updating ffmpeg. I even re-ran ./configure in my ffmpeg build with "--enable-libmp3lame", but, still, I get this error message.

I can convert files to mp3 using the libmp3lame codec in ffmpeg, but for some reason the "--audio-format mp3" command in youtube-dl isn't recognizing it.

aren't there different choices for mp3 de/encoders with ffmpeg?

I updated to the 04-06 release of youtube-dl, and I still get the same error message. I also tried the --verbose setting. This is what I get

There may be; I don't know .The default encoder chosen by youtube-dl is giving me trouble. Oddly, though, libmp3lame works fine when running it directly from ffmpeg. Youtube-dl still doesn't recognize though.

Maybe there's a way to get youtube-dl to use one of these other mp3 encoders? For now, I'm just running a shell script for ffmpeg that converts all the youtube audio formats to mp3, but I'd still like to get to the bottom of why the "--audio-format mp3" option isn't working in youtube-dl.

It may have something to do with avconv.

weird.
can't reproduce (on archlinux).

what versions of youtube-dl, ffmpeg and libmp3lame are you using?
which distro (version, architecture), and is it updated & upgraded? in other words, did you run "apt-get update && apt-get upgrade" or your distro's equivalent?

and it works when you use avconv directly? can you show us the command you used to test that?

Your copy of youtube-dl seems to be using avconv which probably is not fitted out for mp3 encoding:

Code:

[debug] ffmpeg command line: avconv -y -i 'fil[...]

Perhaps your best option is to use these two options:

Code:

--prefer-ffmpeg
--ffmpeg-location <path to FFmpeg executable>

Hopefully this will be enough....

I have the same problem as NathanSharp. --prefer-ffmpeg is a workaround that works for me. Maybe recompiling libav after installing lame will fix the original issue.

No, if your --verbose log shows that youtube-dl is trying to use avconv instead of FFmpeg
then your avconv needs to be re-compiled with --enable-libmp3lame imho.

That is what I was implying.
