PropertiesChanged signal on wrong interface

[eladyn]

As the Metadata as well as the PlaybackStatus properties are both properties on the org.mpris.MediaPlayer2.Player interface, the emitted PropertiesChanged signal should be also for this interface.

Instead, it uses org.mpris.MediaPlayer2:

See also the output of dbus-monitor:

Thank you!

Thanks for pointing this out! Just commited a fix in the master branch. Is it working properly now?

[eladyn]

Yeah, it is. Thank you!

This is the native GNOME Shell mpris indicator. I don't know why, but it isn't showing the artist; might be a problem on psst's side (I will investigate that further). If necessary, I will create another issue for this.
