MPRIS2 D-Bus for a (remote) Mopidy instance
Project description
mopidris
MPRIS2 D-Bus for a (remote) Mopidy instance.
Background
Many desktop environments can control a media player through the
D-Bus via the
Media Player Remote Interfacing Specification (MPRIS)
interface. To control a locally running instance of Mopidy, there exists the
Mopidy-MPRIS
package:
- https://mopidy.com/ext/mpris/
- https://pypi.org/project/Mopidy-MPRIS
- https://github.com/mopidy/mopidy-mpris
For this to work, Mopidy has to run on the same computer as the the D-Bus. If Mopidy runs on a remote server, up to now there was only the following solution available:
- Install and enable the MPD interface for Mopidy:
- Install
mpDris2
. - Start
mpDris2
, whenever you log into your desktop environment.
The mopidris
introduced here, connects directly to a local or remote Mopidy
without the detour through the mpd
interface.
There is an additional (and probably controversial) feature implemented:
Internet radio streams do often send artist and title as one metatag. If those
two fields are separated by " - "
, it is split and presented as artist and
title to the D-Bus. (This is the default behaviour and can be switched off with
the --no-mangle
command line parameter.)
Installation
pip install mopidris
This installs these additional packages:
dbus_next
>= 0.2.3mopidy_asyncio_client
>= 3.0.1 (andwebsockets
as a dependency)
Optional packages
You can install the following optional packages. mopidris
makes use of them,
if it can find them, but it also works well without them:
aiorun
: If the event loop is terminated with CTRL-C, sometimes the port is not released and 'mopidris' cannot be restarted. 'aiorun' can help here (but it can still happen, that the DBUS hangs ...)colored_traceback
: Shows coloured tracebacks, to help debugging exceptions.colorlog
: Colour the log to make it easier to read.
Usage
Command line
The program is started with
python3 /path/to/mopidris
e.g. if mopidris
is installed into the directory
/usr/local/lib/python3.8/dist-packages/mopidris/
, call it with
python3 /usr/local/lib/python3.8/dist-packages/mopidris
The most important options are undeniably the (optional) positional parameter
specifying the host and possibly --retries
and --can-quit
. For the full
list, see the section "Command line options" near the end.
Configuration file
Instead of giving the parameters all the time when calling mopidris
, it is
possible to write them into a configuration file. The default location can be
found by calling python3 mopidris --help
(look for the --config
option).
A possible configuration file can look like this:
# Remote host ip
host = 192.168.0.1
# Retry forever
reconnect_attempts = -1
# Wait 60s between retries
reconnect_timeout = 60
.desktop
file
If this mopidy.desktop
is installed (e.g. into /usr/local/share/applications
or to
${HOME}/.local/share/applications
, it is probably possible to start
mopidris
on a Linux system from the sound applet. For this to work, the file
has to be named mopidris.desktop
and the program at least started once
manually!
Do not forget to update the path in the file to your installation directory!
Start automatically
There exists two possible ways to start mopidris
automatically, whenever a
user logs in:
Startup Applications
Put python3 /path/to/mopidris
with the required command line options (or a
configuration file) into your Startup Applications
.
If you have installed the mopidy.desktop
file as described above, this file
can be used in the Startup Applications
.
systemd service
NB: This is not tested, so please feel free to open an issue and post a correction to the procedure!
It is also possible to start it via a systemd service.
Copy the
mopidris.service
file
to /usr/lib/systemd/user
(or the user's equivalent) and activate it with:
systemctl --user enable mopidris.service
systemctl --user start mopidris.service
Command line options
To see the command line options, call
python3 mopidris --help

[HOST]
Connect a (remote) Mopidy instance to the local DBus.
positional arguments:
HOST the remote host name or ip address
(default: localhost,
configfile key: host)
