Playlist does not play

Hi,

now that I got mpd running and playing music, I am trying to import my playlists. The files I try to play are flac files.

To simplify things, I created a playlist with just one track (see below). My music is in /music/local/flac. The playlist is in /music/local/flac/00_playlists. I understand that the playlist must contain the paths relative to the music_directory specified in mpd.conf.

Code: Select all

#EXTM3U
#EXTINF:431, Herbie Hancock - Watermelon Man
/Herbie Hancock/Cantaloupe Island/Herbie Hancock - Watermelon Man.flac
I believe that the .m3u does specify the path correctly. The file exists in that directory. When I try to play the playlist using MALP, I get "Access denied".

Here is the ls -l output for the directory, subdirectory and the file:

Code: Select all

drwxrwxrwx 1 mpd audio 131072 Nov 15 22:57 'Herbie Hancock'

drwxrwxrwx 1 mpd audio 131072 Nov 15 22:57 'Cantaloupe Island'

-rwxrwxrwx 1 mpd audio 51441810 Feb  6 01:16 'Herbie Hancock - Watermelon Man.flac'
As you can see, I made user mpd and group audio chown all the relevant files and in addition applied chmod 777 to rule out permission problems.

This is the /var/log/mpd/mpd.log:

Code: Select all

Feb 07 00:14 : client: [4] opened from 192.168.1.26:46664
Feb 07 00:14 : client: [5] opened from 192.168.1.26:46666
Feb 07 00:14 : exception: Access denied
Feb 07 00:14 : client: [5] closed
Feb 07 00:14 : client: [6] opened from 192.168.1.26:46674
Feb 07 00:14 : client: [6] closed
Feb 07 00:14 : client: [7] opened from 192.168.1.26:46676
Feb 07 00:14 : exception: Access denied
Feb 07 00:14 : client: [7] closed
Feb 07 00:15 : client: [4] closed
Does anyone have an idea what the problem is?

Thank you!

Here are the relevant parts of my mpd.conf

# This setting controls the top directory which MPD will search to discover the

# file:// protocol) or streaming files over an accepted protocol.
#
music_directory         "/music/local/flac"
#
# This setting sets the MPD internal playlist directory. The purpose of this
# directory is storage for playlists created by MPD. The server will use
# playlist files not created by the server but only if they are in the MPD
# format. This setting defaults to playlist saving being disabled.
#
playlist_directory              "/music/local/flac/00_playlists"
#
# This setting sets the location of the MPD database. This file is used to
# load the database at server start up and store the database while the
# server is not up. This setting defaults to disabled which will allow

# These settings are the locations for the daemon log files for the daemon.
# These logs are great for troubleshooting, depending on your log_level

# The special value "syslog" makes MPD use the local syslog daemon. This

# This setting sets the location of the file which stores the process ID

# default and the pid file will not be stored.
#
pid_file                        "/run/mpd/pid"
#
# This setting sets the location of the file which contains information about
# most variables to get MPD back into the same general shape it was in before
# it was brought down. This setting is disabled by default and the server
# state will be reset on server start up.

Your MPD version is very old and unsupported.
But it looks like your M3U contains absolute paths. Can you confirm that there exists a directory named "Herbie Hancock" at the very root of your Linux installation?

I did not expect that my version was outdated because I just installed it. I will run an update before doing anything else.

No, I do not have the directory in my root directory. I was not aware that the paths are absolute. The intention was to specify a path relative to the music directory. I just learned that the leading "/" makes it an absolute path. Removing the "/" did the trick.

Thanks!

You're probably a sad Debian user. Debian ships outdated and known-buggy package versions and they call it "stable". That gives me lots of support headaches.
