MPD

MPD (Music Player Daemon) is a light-weight server for streaming music. Because it's a server you'll also need a client to tell the server what to do, but this setup means you can run the server on one computer, and use a number of other devices to control it.

Notes on Clients

Haven't Tried

Just listing some GUI clients I might try at some point.

QNAP

Notes on using MPD on a QNAP TS-231P. Setup to work on my local network only.

I used this package from a third-party repository (see: Install our repository, if needed).

NB: Qnapclub is basically dead now, but the MPD package on it's replacement is currently not available due to an error (https://www.myqnap.org/?s=mpd)

The files you need are in /opt/MPD/, to start you'll want to get into the config. file at /opt/MPD/etc/mpd.conf

(It's also worth mentioning that the error log file is at /opt/MPD/var/log/mpd/mpd.log)

A lot of the defaults of fine, but:

When the config's ready you can start or restart MPD through the NAS's web interface, or through running ./mpd –kill from /opt/MPD/bin (it will restart itself).

You don't need to forward ports unless you want to access MPD from outside the local network.

Only option I have for output is HTTPD. This has a bit of lag when doing things like skipping songs and starting that is slightly annoying, so if you can use something else I recommend doing that.

Playlists

Got stuck on this for a bit because it's weird.

The playlist_directory you configure is meant for playlists made with MPD. Deceptively, it uses .m3u files, but they're not standard (m3u is barely a standard…): They're a plain list of file paths relative to configured music_directory, they work just fine with Unicode, they don't use the #EXTM3U header, and if you create them outside of MPD and put them here they won't read the first line.

You can, however, load many kinds of playlists from other directories, but I've had mixed results with this: MPDroid doesn't seem to see playlists in music_directory, so I've only had luck using absolute paths; ncmpcpp shows playlists from playlist_directory and music_directory on the browse page, and the ones in music_directory work fine with relative paths.

If you do want to manually make playlists by hand, or by exporting from your Music Player, give them an .m3u extension, leave the first line blank, make the paths relative to the configured music_directory, and don't add anything else.

So they should look something like this:

Bowie, David/[1974] Diamond Dogs (30th Anniversary Edition)/1,06 Rebel Rebel.mp3
Bowie, David/[1973] Aladdin Sane (30th Anniversary Edition)/2,11 John I'm Only Dancing (Sax Version).mp3
Bowie, David/[1973] Pin Ups/08 Sorrow.mp3
Bowie, David/[1975] Young Americans/08 Fame.mp3
Bowie, David/[1972] The Rise And Fall Of Ziggy Stardust And The Spiders From Mars/10 Suffragette City.mp3
Bowie, David/[1971] Hunky Dory/02 Oh! You Pretty Things.mp3
Bowie, David/[1971] Hunky Dory/12 Bombers (previously unreleased) [bonus].mp3
Bowie, David/[1983] Let's Dance/01 Modern Love.mp3
Bowie, David/[1975] Young Americans/01 Young Americans.mp3

If you load this in MPD, then resave it, it'll sort out that first line silliness.

Cover Art

MPD now supports cover art. It'll grab any image in the same directory as the file called cover.[png|jpg|tiff|bmp].
