Support mopidy

[GijsTimmers]

I'm using pms v0.42 on Ubuntu 17.10.

pms works nicely with mpd, but doesn't with mopidy. The main problem is that tracks don't show up in the library.

It would be nice if pms supported mopidy.

Hi @GijsTimmers.

Mopidy support is definitely a feature I'd like to implement some time soon, but version 0.42 is unsupported and there is not going to be any further development on that branch. Maybe you'd like to try the current git master instead and see how it works?

[GijsTimmers]

Hi @ambientsound, thanks for your quick response. I will try that out first.

Hi again, Did you have any luck using master with Mopidy?

Hello Kim,

Haven't tried it in the meantime tbh. Still interested though.

Can confirm that master of pms does not work with Mopidy right now, and will instead spit out:

However, and this is interesting, if I start pms with a running instance of mpd, kill the mpd instance, then start Mopidy, pms is at least able to list the songs currently in the queue, even if the songs are from a remote source like Spotify.

Well, it looked like what little I was able to get working was a fluke, as I can't reproduce it now.

[dvdmuckle]

Well, I was able to get it so I can switch tracks in the current queue, which was added from another client.

This error might signify that PMS was not able to pull a full copy of the song library from MPD. This makes sense since this information might not be available from Mopidy. Because PMS' search is based on having this information stored locally, a bigger refactor will be needed in order to fully support searching through Mopidy.

[dvdmuckle]

That sounds about right, especially considering if other music backends like Spotify are enabled, which present a very large library to look through.
