MPD - time for an update?

[donquixote2u]

@Jason

In principle, I support your intentions. But my version is also different in functionality.

The original TC version (and also the version of b1ackmai1er) supports e.g. no mp3 streaming (I need it but for my iPod) etc ...

I have included in my version as much as possible options. This makes this version of course, larger (more dependencies) :

Maybe we can escape this catch 21 situation by renaming my version to "mpd-max"?

TaoTePuh's version now includes icecast/shoutcast capability, thereby addressing my concerns about weaknesses in previous versions, so is just fine for my use;

I found my own cut-down local mp3/OSS version wasnt THAT much smaller, so I'd be happy to run with this version as the official mpd 0.15 version. I think the "generic" mpd.tcz version does need to cover as many bases as this one does.

In the meantime I'd like to suggest to blackmailer that he could perhaps ready an 0.16 "mpd-testing.tcz" version along the same lines (ie libs in separate packages), or maybe do a bundled "nodeps" version? 

oh and btw TaoTePuh I stand corrected on the mpc remote capability, thanks for pointing that out, so mpc CAN stand without the mpd dependency. 

[Jason W]

I think donquixote has a good idea for this extension.

[TaoTePuh]

I have finally got a script for compiling mpd. I can quickly adapt this to all needs (git-version, more/less options etc).

But I am waiting for b1ackmai1er's and the community's answer whether to continue or not ...

[Jason W]

mpd.tcz in the repo needs to be at least corrected in regards to file contents.  And I see mpc.tcz has three instances of appended data to it, indicated by the top level usr_1, usr_2, and usr_3 directories.  I have a check for appended data in the audit script, but somehow it slipped past me.

Tonight I will correct the appended data issue with the mpc.tcz extension.  

Tao has taken the steps to communicate and resolve the mpd issue, and his build appears to be best suited for being the main mpd.tcz extension.  So please submit the latest stable one as mpd.tcz, I see no reason for further delay.

[TaoTePuh]

Okay, I'll send version 0.15.12 (last stable) as mpd.tcz.

But how shall I name version 0.16 (git, alpha)?

mpd-testing.tcz
mpd-git.tcz
mpd???

Or do you not want me to submit it?

[Jason W]

-git or -svn is a pretty good name for a cutting edge version, as git or svn versions may change in between alpha and beta and RC status.

[cyco_mf]

Blackmailer has submitted mpd.tcz, which was previously done by Davor Serfez.  

And TaoTePuh has submitted the closely related gmpc set of extensions.  

Since this all has been discussed in this thread at length, I am assuming everyone is ok with it.

Any concerned parties can contact me if this is an issue.

Jason W I am glad you posted this, since I was wrestling with some of the issues involved. I dont own mpd, but certainly do own the starting of this thread, so felt a bit responsible when it looked like we were going to have two versions of mpd!

As it has happened it seems to have worked out well. We havent heard from Davor so I assume he is off doing other things - hopefully this thread circumvents the issue we have had recently with original extension submitters having their toes trod on by new versions surfacing without appropriate consultation.

Blackmailer put his hand up for the re-compilation so it looks like he's "it" as mpd maintainer now.  Between his proposed compile options and TaoTePuh , the only question I have (and probably an ignorant one    ) - what about icecast streaming?  Is shoutcast the same thing?  This seems to be quite commonly used mpd feature with other distros. It (streaming) is on my to-do-one-day list so I'd better find out!
  
Anyway good to see the prolific TaoTePuh  has now added gmpc!  he certainly has become a very good mpd client contributor now.

Now to a few more comments:

I have compiled and submitted the latest alpha version which supports the mpd.conf file in /opt/.mpd

well that is where I think both I and SamK put our mpd config, so ok by me , BUT I hope mpd isnt being started out of tce.installed since I dont have my mounts done by that stage - so to that extent I like  TaoTePuh's roll-your-own approach to config.

Thanks for the idea but there is no "default mpd.conf" in my extension. The settings are too individual.

There is only a "example conf" in /usr/local/share/doc/mpd/mpdconf.example but this will never work without manual adjustment.

I would like to place the following hint in the info file for the Appbrowser:

CONFIGURATION
-------------
Copy example configuration
    tce-load -i mpd-0.15.12-doc
    sudo cp /usr/local/share/doc/mpd/mpdconf.example /etc/mpd.conf
Modify (with sudo) /etc/mpd.conf according to your requirements
Put mpd.conf in your backup if /etc is not persistent
    echo "etc/mpd.conf" >> /opt/.filetool.lst

START mpd
---------
sudo /usr/local/bin/mpd /etc/mpd.conf

STOP mpd
--------
sudo killall mpd

 It bypasses both the stop/start issue with mpd, and that of where the config file is - just put it where you like, before you start mpd! Blackmailer, what was your approach here?

 

Hi, Davor Serfez here.
Thanks for all the nice words for my work with building the mpd extension and documenting the procedure. I'm very glad if it helped in learning and creating an improved extension which deserves to carry the 'mpd' name. I am not a tinycore user but I find microcore to be a fantastic platform for building virtual or embedded appliances for the x86 architecture (that's why I created the mpd and postal extensions).
Keep on the good work.

[donquixote2u]

Good to see Davor approves of the work done in his footsteps! 

- further to recent discussion on the minimal/nodeps version,  it may be difficult to define what to leave out, but I'm gonna leap in where others fear to tread anyway!

Davor's v2.x version left out shoutcast, so maybe the mini version should be a local player only? leave out the lame, httpd etc? mpd-player anyone?

I must admit I eventually went with my own cut-down version for the same dep-bloat reasons, but it is an mp3-only version, with lame and httpd for mp3 streaming. Thats another version possibility, mpd-mp3?

we almost need a poll with a few popular options , eh!!!

[hiro]

This should be mpd.tcz: mp3,flac,vorbis,aac,wave,curl,samplerate,cue,id3-tag,oss
Minimal enough for me.

[TaoTePuh]

FYI: I have just submitted mpd 0.16 and some stuff for usage.

Here is the summary of compiling options:

##########################################

Some notes on configuration :

• Support for Avahi was enabled for compiling but is displayed with (-Avahi) --> (Bug?).
• Support for libsndfile is disabled (-libsndfile) because it conflicts with libmodplug (both have a file named sndfile.h)
• The support for "FireWire based audio devices" (+FFADO) is new in mpd 0.16 but not tested by myself - I don't have the necessary equipment

And here is the resulting support :

[hiro]

I saw these new extensions. Most of the dependencies are overkill.
The dependency files from my old extensions in the 2.x archives might be a starting point.

In general I suggest people should not build extensions they don't ever use.
Test them at least one time.

If there is any demand I can support ffado and similar extensions. I didn't update them, because there weren't any other users anyway and I still use tc 2.x on my daw.

[gutmensch]

@Tao: at least libffado needs rework, please put only libffado.so* into the libffado extension and the rest splitted into ffado. there are many people who don't want to (or cannot) use these drivers at all, and they surely don't need qt or ffado python scripts or pyqt etc. for running mpd. if libffado requires too many compromising trade-offs, then think about leaving it out completely...

[edit]
I would also suggest to include in the mpd info file that you don't have to run mpd as root, it's sufficient to be run as normal user on port 6600 with own configuration data in the home directory. It's not very common to run processes as root if you're not forced to do so.
[/edit]

[TaoTePuh]

... the libffado extension ...

I have just submitted an updated version. I hope it's better that way.

I would also suggest to include in the mpd info file that you don't have to run mpd as root, it's sufficient to be run as normal user on port 6600 with own configuration data in the home directory. It's not very common to run processes as root if you're not forced to do so.

There is no problem with the "sudo" if you deal correctly with the option "user" in "mpd.conf".

But if you change "user" to something different than "tc" (maybe "user mpdrun"), you have to start with "sudo" if you logged in as tc. Okay, I admit that this case at TCL is relatively unlikely. But "sudo" is the universal variant.

I agree we should probably write more about this problem.
But we should not forget that many people start mpd out from the script bootlocal.sh and then (if option user is unused) mpd runs at root, doesn't it?

Here is my suggestion for the .info file


START mpd
---------
/usr/local/bin/mpd /etc/mpd.conf
Save this in your /opt/bootlocal.sh if mpd should
be started automatically at boot time.

Note if start mpd out from /opt/bootlocal.sh:
You should deal with the option "user" in
mpd.conf so that mpd doesn't run as root.

[gutmensch]

from bootlocal.sh I run mpd with

Code: [Select]

su -c '/usr/local/bin/mpd' tc
which prevents mpd from getting root privileges.

my .mpdconf file in /home/tc looks like this

Code: [Select]

port    "6600"
music_directory         "/mnt"
playlist_directory      "~/.mpd/playlists"
db_file                 "~/.mpd/mpd.db"
log_file                "~/.mpd/mpd.log"

the drives under /mnt are user rw (in my case ntfs-3g).

I'm not saying that there aren't any good reasons to start mpd as root (although I cannot think of one atm) but as long as it is just unnecessary I wouldn't go this way because it's only providing a certain risk, no gain at all.

[hiro]

Today I wanted to start the ffado-mixer, but there is none in libffado. Perhaps you could create a ffado-tools package or something like that?
