I am able to download .webm files from YouTube with the
youtube-dl utility.
Now, I would like to be able to take just the
audio track of such a file and write it to a .ogg or .mp3
file. Can someone coach me how to do this?
Thank you for your help.

ffmpeg should allow you to take the audio track.
ffmpeg -i whatever.format -vn -ac 2 -ar 44100 -ab 320k -f mp3 output.mp3

Hello Ivan!
youtube-dl offers an option to automatically extract audio see:
youtube-dl --help
youtube-dl --extract-audio -T URL
should render a file with a name of the video and audio only. Youneed avconv
and avprobe or ffmpeg and ffprobe for this to work.
If you can't manage those tools, then ue mplayer. the -dumpaudio and
-dumpfile options are your friends. Something like this should do the trick:
mplayer -dumpaudio -dumpfile output.ogg input.webm
As far as I know, .webm has an OGG/Vorbis audio stream, so this should work.
If not, I have a script to convert any mplayer-=supported file format into
mp3.
Warm regards
Julien

The audio track in a youtube file *is* Vorbis (in an mkv container).
Don't have ffmpeg reencode it, just de/remux it.
... I don't have a command like handy though :-| Can't be too hard
with gst-launch though.

Hello Monty1
The same result would be achieved by the mplayer -dumpaudio command. Don't
know gst-launch. Can it work on the commandline only? Could it be built into
scripts as well?
Best wishes
Julien

ffmpeg ... -acodec copy ...
should do the trick (so remove all output settings for the audio track)
