Mopidy MPD doesn't return Cover Art URI

Q&A
1

Hi, I have just completed an installation of mopidy from scratch on a buster PI. I added mopidy-mpd and mopidy-local as both appear to be needed to get a working solution. Running Mopidy as a service, and after scanning the files with local scan, I can see that the images have been created in /var/lib/mopidy/local/images and the URIs are in the database library.db for the albums.
But, when I request track data via the MPD interface, the X-AlbumImage field is not being returned. This was i presume previously provided through the local-images extension, but this is now deprecated in favour of mopidy-local.

Can anyone point me in the right direction to enable the album image information to be returned for tracks via the mpd interface. thanks

That feature hasn’t been implemented yet. I gave it a go last year, but don’t really know Python well enough.

Hi to an extent answering my own request in case anyone else needs this - the original x-albumimages field was an addition to the standard MPD tags returned from Mopidy. This hasn’t been carried over to the new version however all the work has been done in local to extract and store the images in the DB. I am looking at how to add this back as a patch however at the moment it covers a lot of modules.

Which extension are you talking about? Mopidy-mpd or Mopidy-local? Or both? It looks like like Mopidy-local already supports images. MPD is the one that doesn’t support images.

It’d be better for Mopidy-MPD to implement MPD’s albumart and readpicture commands instead of reviving x-albumimages. Support MPD albumart and readpicture command · Issue #17 · mopidy/mopidy-mpd · GitHub

hi

making a small amount of changes to the code in mopidy, -local and -MPD meant i re-enabled x-albumimages. i understand this is deprecated however the alternative solution, would require a possibly quite complex change to the code and my MPD clients. If and when albumart and readpicture is enabled i will look at how to incorporate it into the code. thanks for the responses.
