I tried to extract audio from a video by running this:

youtube-dl -x --audio-format m4a URL

And I got an error message. My youtube-dl's version is 2016.02.13

Full error code is:

Post the full output of youtube-dl when run with -v, i.e. add -v flag to your command line, copy the whole output and post it in the issue body wrapped in ``` for better formatting. It should look similar to this:

Do not post screenshots of verbose log only plain text is acceptable.

The output (including the first lines) contains important debugging information. Issues without the full output are often not reproducible and therefore do not get solved in short order, if ever.

@watarumohawk you must use your URL in verbose output not BaW_jenozKcj.

@dstftw youtube-dl -v URL and youtube-dl -v -x URL are fine, but youtube-dl -v -x --audio-format m4a gives me an error.

Here is three results.

Bit of an old thread, but hey...
@watarumohawk This isn't a youtube-dl bug, rather ffmpeg doesn't support m4a (ie aac) conversion out of the box as it is a non-free format. You can compile ffmpeg yourself and enable libfdk_aac using --enable-libfdk-aac: https://trac.ffmpeg.org/wiki/Encode/AAC
While there isn't an official build of ffmpeg with lbfdk_aac, if you do some googling you may be able to find a build you can use (ffmpeg Hi for example: https://sourceforge.net/projects/ffmpeg-hi/).
