System and session bus are diff why?

[tr1xem]

Using session bus its mpd (and it dont have art url or anything) while on system bus its mopidy which is better as it have art url

Can i ask why is that?
Is it possible to have both same?

[kingosticks]

I don't understand the first sentence. Could you rephrase it?

[tr1xem]

Sure
There are 2 options in mopidy-mpris system and session bus

When its set to system bus in settings its getting identified (by playerclt) by name mopidy and when i see the metadata of the player ie mopidy its like normal contains spotify art url too

The problem arise when i set it to session bus now its getting identified by name mpd and the metadata dont contain any arturl

Is it a feature? or a bug

Disclaimer: there has been a few years since last time I looked at MPRIS.

There shouldn't be a difference. Are you certain you are communicating with the same installation of Mopidy?

Mopidy should never self-identify as MPD. Is there maybe an MPD installation as well, independent from Mopidy, that is available on the session bus?
