MPD installation howto (updated 4 May 2009)

[gwillem]

Update October: Awesome! AlanH has again put considerable effort in our MPD version. He created the structure required to abide the (GPL) law. There's no CSI package yet but refer to this post in another thread for installation instructions. Great work Alan!

Update 4 May: New mpd version from Alanh fixes bug with playing video's after using mpd, better AAC support, better hardware mixer support. Also new version of mpc-ird (remote control) by RICOUK and Glorifyday. Als fixed problem with HDD spinning up. Thanks guys! Todo: mpd/gpl-compliant build system, CSI compatible package, mpdscribble.

Update 8 April: Fixed remote control bug. Again thanks to Alan H, now supports streaming & FLAC!

Update 21 March: thanks to Alan H, no more USB device required! Work in progress: HDMI output (currently only analogue output works), live streaming, last.fm scrobbler.

MPD is a standalone network music player that can run independantly on your NMT. It supports many features and plugins, such as remote control (Iphone, PC, IR), playlists and streams. It does not output anything to your screen.

Make sure your NMT is non-idle (orange led on the PCH!). Log into your NMT through ssh or telnet. Uninstall previous version and reboot if you got any older version (see below). Then issue these commands.

edited by Werner: i removed the link to the package which seems to break the GPL, you can read the reason for that here http://www.networkedmediatank.com/showth...#pid207623

Code:

cd /share
wget LINK REMOVED, GPL ISSUES FOR mpd-nmt-20090504 -qO - | tar xvz
cd /share/Apps/mpd
sh install.sh
sh daemon.sh start

First startup will take some time, because it will index all the music in /share/Music. Note that you don't have to start anything manually next time, because mpd will be loaded on boottime automatically. Now, you can start your favourite MPD client. I use GMPC for Linux, Minion for Firefox and MPoD for my iPhone but there are many others. I included a local client. Try these commands:

Code:

mpc ls | mpc add
mpc play
mpc status
mpc next
mpc pause
mpc add http://89.238.146.144:7010

Remote control
You can also use your remote control, but only when the NMT is in standby/idle mode (red led). See this post from RICOUK and this post from glorifyday for instructions.

Uninstallation

Code:

mpc stop && sleep 3
killall mpd
killall mpc-ird
rm -rf /mnt/syb8634/etc/mpd
rm -rf /share/Apps/mpd
sed -i '/\/mpd\//d' /mnt/syb8634/etc/ftpserver.sh
sed -i '/\/daemon.sh\//d' /mnt/syb8634/etc/ftpserver.sh

Enjoy your music!

Hi gwillem,
thnx for this howto.
First of all, following this howto made mpd running on my pch with creative sound blaster usb device.

But mpd seems to ignore the id3-tags.
Minion (firefox plugin) shows no albums, no artists, only folders like REM, A-HA, etc. and contained files.
The mp3 files in these folders are shown e. g. as
REM/Reveal/01 - Reveal - REM - The Lif.mp3
like
"folder/subfolder/name of file"
MPod on my iphone shows:
Unknown Artist, Unknown Album, Unknown Song.

I'm sure the mp3 files are fine because another mpd on Ubuntu 8.10 shows all id3 information of same sound files.


Please give me a hint to fix this issue.

Some further questions:
Is it possible to control (stop, restart, update, etc) mpd on pch with telnet?
How to uninstall mpd?

Greetings to Amsterdam
tonne

[gwillem]

I excluded the Id3 parsing on purpose to speed things up (it will take a while to index my 300+ GB of music :-)) but I see this messes things up for the Ipod control. So I made a new version with id3 parsing (see download link above). Make sure to delete your tag_cache file and restart mpd.

Also added sections for telnet control, ir remote control and uninstallation.

Enjoy your music!

now, I havn't tried it YET, but thats how a "how2 guide" should be written.
I Know, I've PM'd you, but i actually was looking for a "how2" guide to telnet (or other way to get control/command line access) to NMT box. (maybe there was other dumb people like me who?)

Have you made one of these or is it out there? (sorry for offtopic)

[gwillem]

Hi Andemad, did you try installing telnet through http://www.nmtinstaller.com/ ?
I think it's so easy you won't need a howto

---

It was released just yesterday, so I'd expect it to be fixed any moment.

[Andemad]

It worked like a Charm.

I'm not sure, that I've done it right. I got some "error messages" in the commandprompt.

Btw, when adding music later on, one should run the start ./startmpd.sh again, or?

[gwillem]

Andemad, can you paste the output of

Code:

find /mnt/syb8634/etc/mpd
lsmod
ls -lad /mnt/syb8634/etc/mpd

And afterwards, try rebooting. Can you connect with a client? Can you push "play" on the client?

You dont have to run ./startmpd next time, it will be started on boot automatically.

Thanks - output below

no, i havn't tried it with the client, because I wanted to see, if i worked, before i bought a ipod Touch/iphone which were my original idea - I'm a little cautious newbee, i know..

Strange...

Can you try, before buying an Iphone this client? https://addons.mozilla.org/en-US/firefox/addon/6324

Can you reboot and do this:

Code:

insmod /mnt/syb8634/etc/mpd/modules/soundcore.ko
dmesg | tail
lsmod
uname -a

Also, what NMT brand/model do you have?

[Andemad]

Update, sorry - the player DID find the songs! but when i press PLAY it seems to start and then stop again without playing. Of course, I do not have an USB audio thingy yet, but it does not seem to be playing.

[gwillem]

Andemad, please read the howto carefully. It says to first plugin a USB audio stick

So get one. If you plug it in, reboot your NMT and all should be fine.

Good luck!

[Andemad]

D'oh! Sorry! Didn't think it would matter so much. but of course - that makes sence!

Thank you very much! Hope it will be the last of it

[Andemad]

Just added an audio device. not sure it works... I thinks

Code:

# mpc ls | mpc add
adding: Celina Ree - Kortslutning
adding: Volbeat_-_Maybellene_i_hofteholder_(2008)
# mpc play
Celina Ree - Adrenalin
[playing] #2/14   0:00/3:05 (0%)
volume:100%   repeat: off   random: off
# mpc status
volume:100%   repeat: off   random: off
ERROR: problems opening audio device
# mpc next
volume:100%   repeat: off   random: off
ERROR: problems opening audio device
# mpc pause
volume:100%   repeat: off   random: off
ERROR: problems opening audio device
#

It pretty much states, thats my usb-audio thats not working, right? I think it requires a driver, but i'm not sure how to install a driver on the linux box (pch a-100) HDX1000 - but, would you say, that if i buy one of those usb-audio-things that YOU linked to, it would probably work?

[gwillem]

Andemad, we won't give up until your sound is working ;-)

Can you unplug your usb audio, plug it in again and then send us the output of "dmesg | tail" ?

Any chance you can hook up your HDX to the net so I can take a look remotely?

[Andemad]

oooooh my goood! IT WORKS!!!!!!!!!!!!

Thank you, thankyou, thankyou

Now, to buy an ipod touch and install another client. I works with minion..

But i consider another USB device (eg. creative X-FI usb), since the audio quality is not that good. Its almost like its peaked out / too high gained, and i blame it on the usb or my amplifier. I don't suppose the NMT has nothing to do with the output...?

But it works! a little delay from pushing the button (i expected that) but goddamnit - it just works! You're the greatest man, i owe you!
