DBus trouble adding song to playlist in Python

Added by Kristian Kjærgaard about 11 years ago

I have a Python script that looks like this:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import gobject
import dbus
from dbus import glib

gobject.threads_init()
glib.init_threads()

bus = dbus.SessionBus()

remote_object = bus.get_object("org.atheme.audacious", "/org/atheme/audacious")
iface = dbus.Interface(remote_object, 'org.atheme.audacious')

song = "/home/user/song.mp3" 

iface.Pause()
iface.PlaylistAdd(song)
iface.Seek(55)
iface.Play()

But in the Audacious window, the song appears as the filename given in the string "song" and not as "Author - Title" as other songs do. When double-clicking the song I have to click OK to "No decoder found for /home/user/song.mp3."

What am I doing wrong?

Make sure the MP3 plugin is enabled?

If I drag and drop the file into Audacious it plays without trouble. The filename is also replaced with "Author - Title". The file plays if i execute "audacious /home/user/song.mp3". So the MP3 plugin should be enabled.

The debug messages related to the problem is written below.

It seems I just forgot the protocol. If I append "file://" to my song filename in the Python script, everything works.

song = "file:///home/user/song.mp3"

Sorry about the fuss.

Hmm, yes, the D-Bus API is a pretty thin wrapper around the internal functions, and those expect a URI.
