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
- ncmpcpp - Curses-based client that seems more full-featured than any of the available GUI ones. Good tag management, which includes being Picard-friendly. Because my NAS doen't have any kind of audio hardware I still need a Music Player that can handle streams (Mplayer, FFmpeg, VLC, etc.—even a web browser works) to actually hear the audio.
- Ymuse - Simple GUI client.
Haven't Tried
Just listing some GUI clients I might try at some point.
- Cantata cantata CDrummond/cantata - Finished
- QMPDClient qmpdclient https://bitcheese.net/QMPDClient/
- myMPD jcorporation/myMPD - Light, browser-based client.
- Maximum MPD rbackhouse/MaximumMPD - Semms to have a good UI and features, but doesn't do streaming?
- There are some Rofi-based ones that seem interesting too…

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:
- Check your
music_directoryandplaylist_directory - Check your
user - I can't remember what was set initially, but you can comment out
bind_to_address, as the default works. - Review
log_level,gapless_mp3_playback,restore_paused,save_absolute_paths_in_playlists,auto_update. - Check the password stuff.
- Curl input plugin's just for Internet stuff so I disabled it.
audio_outputdepends on your usage. My NAS has no soundcard, so I disabled ALSA and enabled HTTPD. If you want to use it to host an Internet accessible stream look at Shout. You can have multiple, and select which are active with your client.- Give your stream a fun name :)
- Check the quality settings.
- Default
formatwas only mono! Change it to“44100:16:2” - And the rest of the file is up to you again.
- If you don't want your output to be resampled you can add and set to
“no”auto_resample,auto_channels, andauto_format
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].
