[emms-help] Error: "Don't know how to play track"

[Marius Hofert]

Hello,

I work with Emacs 24.0.92 (9.0) on Mac OS X 10.7.3. I downloaded and installed
EMMS via "git clone git://git.sv.gnu.org/emms.git" and my ~/.emacs contains...

(add-to-list 'load-path "~/.emacs.d/emms/lisp")
(require 'emms-setup)
(emms-standard)
(emms-default-players)

... as suggested on http://www.gnu.org/software/emms/quickstart.html

If I use M-x emms-play-directory and choose a directory that contains .mp3
files, I obtain:

Don't know how to play track: (*track* (type . file) (name
. "/path/to/music/first song in this directory.mp3") (info-mtime 19612 57269) 
(metadata))

I don't have mplayer installed, but VLC is installed and works perfectly
fine. What additional settings do I need in order for this to work?

Note that the player-list contains VLC (and others -- just the default). I also
set it to *only* VLC, but that gave the same error.

Also note that I found a similar error on
http://superuser.com/questions/179186/emms-emacs-multimedia-system-error-in-emacs-dont-know-how-to-play-track
but the "solution" there does not really explain what the problem is.


Cheers,

Marius
