ERROR: Couldn't attach to DCOP server!

[Bill Moseley]

A year ago I setup a client-server using Perl to remotely run Amarok.
Worked perfectly.  Now I'm running Amarok 2.0.2 on Ubuntu and when the
script tries to connect to Amarok via DCOP I get:

    ERROR: Couldn't attach to DCOP server!

I'm using the DCOP::Amarok::Player Perl module.

This sound familiar to anyone?

Thanks,

Yes. Amarok 2.x no longer uses DCOP. Along with the rest of KDE, Amarok has
switched to the DBus interprocess communicaton protocol. Amarok implements the
MPRIS spec for media players, it can be seen  here:

Ah, well that would explain it.

I see in Perl's CPAN a number of XMMS clients, but I'm assuming those
are not for the xmms2 library.

Big party this weekend and my wife will be very unhappy if I can't
hack up the remote to work. ;)

Can anyone point me to an example client?  I looked over the MRIPS
wiki and then reviewed some of the clients, and specifically the Perl
clients:

    http://wiki.xmms2.xmms.se/wiki/Writing_XMMS2_Clients
    http://git.xmms.se/?p=xmms2-tutorial.git;a=tree;f=perl;h=e9ddb47d9de9f7fb324b2e68d9bf1b14dcf14a7e;hb=c0162aad19da6bce3bfdb3b816bab8a7343a06b0

But, I don't really understand if all the xmms2 info applies to
Amarok.  I couldn't get the example clients above to work --  I
was mostly stumbling around in the dark.

Looks like there's a Perl client module available:

    http://search.cpan.org/~flora/Audio-XMMSClient-0.03/

and I'm hoping it's just a matter of configuring it correctly.
Assuming that it's the correct protocol for Amarok.

Again, I already have a remote control and  I have a Perl
script that reads the key presses.  So, all I need is the interface
to control Amarok.

Thanks,

Which would probably be kdelirc, which is unavailable in KDE until 4.3.
There are probably ways to do what you want by settings amarok  
shortcuts to correspond to your remote keys.
Nope, don't know how.

Ok, well at least I can do a few things, e.g.:

    amarok --play|--stop|--next|--pause

And then control volume separately.  Nowhere as nice as my interface
last year with DCOP, but will do.


My remote is getting pretty old.  Maybe next year there will be an
iPhone app I can make work with Amarok.  I have one for my Slim
Squeezecenter and it's pretty handy.

You could also hack up something that uses qdbus directly, you can
browse around with qdbusviewer (both come with Qt, so you should have
them)

I'm remote-controlling my amarok with my bluetooth-phone. If you own one, you
could do this yourself.

If you have a SonyEricsson-phone (like me):

Yes.  Lot's of apps that relied on DCOP displayed this error in the latest KDE release (4+) so ended up seeing this all over the place after upgrading.  Konsole was one of them.  App developers may have caught up with KDE by now but not sure.

Anyway, I've managed to reenable DCOP following these steps http://www.microdevsys.com/WordPress/2008/12/04/fedora-9-kde-4x-error-couldnt-attach-to-dcop-server/ but your mileage may wary.

This would essentially give you two messaging systems for a while.  Maybe that can work for you until everyone switches to DBus completely.

Ed KB

I took a look at those posts. Seems like it'd be far easier (and faster)
to just port the Perl module to use D-Bus.

dcopserver will launch on-demand.  That blog simply highlights failures due
to botched permissions... once those are fixed, everything should "just
work" again.

Interesting.  As I recall, dcopserver would simply die after being started through applications within the new KDE 4+ environment.  Running /usr/bin/kdeinit as noted in the blog resolved the issue.  I'm curious, what do you mean by botched permissions then?

Thanks,

The blog mentioned permissions, but re-reading, I think I misunderstood.  

True, dcopserver probably does stop running after some time has passed where
no kde3 apps are running.  I don't necessarily consider that a bug.

Sorry for the very late reply, I am finally getting around to looking
into this, almost six months later. I read this page, but it really
doesn't tell me what I need to know. What I want to do is replace my
DCOP remote control script with something that works for Amarok 2.2 .
What I had was this:

#!/bin/bash
dcop --user greg amarok player $*

This meant I could just do

$ ssh musicmachine scriptname pause

from any other machine in the house, and it would pause the music. This
is the kind of thing I want to do. While the methods and XML syntax are
described on the above web page, nowhere does it tell me how to actually
use it to control Amarok. Anywhere I can find info on that?

Thanks,
--Greg

I tried this:

Is there something I have to do inside Amarok to make this work?

Having Amarok 2 running should be enough.

[greg@interface ~]$ rpm -q amarok
amarok-2.2.0-2.fc11.i586
[greg@interface ~]$ qdbus org.mpris.amarok /Player
Service 'org.mpris.amarok' does not exist.

Password:

Tried it as root just to be sure. I know it's running because I hear the
music as I type this.

I tried one more thing: I opened a terminal window while on the console
where Amarok is running. Now it works, but that is useless to me because
what I need to be able to do is ssh in and control the player; if I'm on
the console then I can just control Amarok directly. Is there something
I have to do to be able to make this work other than on the X console?
