Maintainer wanted

Mopidy-Local is currently kept on life support by the Mopidy core developers. It is in need of a more dedicated maintainer.

If you want to be the maintainer of Mopidy-Local, please:

1. Make 2-3 good pull requests improving any part of the project.
2. Read and get familiar with all of the project's open issues.

3. Send a pull request removing this section and adding yourself as the "Current maintainer" in the "Credits" section below. In the pull request description, please refer to the previous pull requests and state that you've familiarized yourself with the open issues.

   As a maintainer, you'll be given push access to the repo and the authority to make releases to PyPI when you see fit.

Installation

Install by running:

sudo python3 -m pip install Mopidy-Local

See https://mopidy.com/ext/local/ for alternative installation methods.

Configuration

Before starting Mopidy, you must add configuration for Mopidy-Local to your Mopidy configuration file:

[local]
media_dir = /path/to/your/music/archive

The following configuration values are available:

• local/enabled: If the local extension should be enabled or not. Defaults to true.
• local/media_dir: Path to directory with local media files.
• local/max_search_results: Number of search results that should be returned. Default is 100.
• local/scan_timeout: Number of milliseconds before giving up scanning a file and moving on to the next file.
• local/scan_follow_symlinks: If we should follow symlinks found in local/media_dir.
• local/scan_flush_threshold: Number of tracks to wait before telling library it should try and store its progress so far. Some libraries might not respect this setting. Set this to zero to disable flushing.
• local/included_file_extensions: File extensions to include when scanning the media directory. Values should be separated by either comma or newline. Each file extension should start with a dot, .e.g. .flac. Setting any values here will override the existence of local/excluded_file_extensions.
• local/excluded_file_extensions: File extensions to exclude when scanning the media directory. Values should be separated by either comma or newline. Each file extension should start with a dot, .e.g. .html. Defaults to a list of common non-audio file extensions often found in music collections. This config value has no effect if local/included_file_extensions is set.
• local/directories: List of top-level directory names and URIs for browsing. See below.
• local/timeout: Database connection timeout in seconds.
• local/use_artist_sortname: Whether to use the sortname field for ordering artist browse results. Disabled by default, since this may give confusing results if not all artists in the library have proper sortnames.
• local/album_art_files: List of file names to check for when searching for external album art. These may contain UNIX shell patterns, i.e. *, ?, etc.

Usage

Generating a library

The command mopidy local scan will scan the path set in the local/media_dir config value for any audio files and build a library of metadata.

To make a local library for your music available for Mopidy:

1. Ensure that the local/media_dir config value points to where your music is located. Check the current setting by running:

   mopidy config

2. Scan your media library.:

   mopidy local scan

3. Start Mopidy, find the music library in a client, and play some local music!

Updating the library

When you've added or removed music in your collection and want to update Mopidy's index of your local library, you need to rescan:

mopidy local scan

Options can be specified to control the behavior of the scan command:

• --force Force rescan of all media files
• --limit <number> Maximum number of tracks to scan

Example:

mopidy local scan --limit 50

Clearing the library

To delete your local images and clear your local library:

mopidy local clear

A prompt will ask you to confirm this irreversible operation.

Library layout

The exposed library has a root directory and nine top-level directories defined under the root directory:

• Albums
• Artists
• Composers
• Genres
• Performers
• Release Years
• Tracks
• Last Week's Updates
• Last Month's Updates

This can be configured through the directories setting. It's expected to be a list of space separated name and URI supported for browsing, eg:

directories =
    Albums                  local:directory?type=album
    Artists                 local:directory?type=artist
    Composers               local:directory?type=artist&role=composer
    Tracks                  local:directory?type=track
    Last Week's Updates     local:directory?max-age=604800

URIs supported for browsing

Remember that URIs are opaque values that neither Mopidy’s core layer or Mopidy frontends should attempt to derive any meaning from. That said, it's necessary to have a sufficient knowledge of Mopidy-Local URIs to customize the directories setting properly.

Browsing URIs starting with local:artist returns references to albums and tracks with the given artist. Browsing URIs starting with local:album returns references to the album tracks. Browsing URIs starting with local:track is not supported.

Other URIs supported for browsing start with local:directory. The returned references are specified through "query parameters":

• local:directory: References to the top levels directories.
• local:directory?type=tracks: References all tracks. Multiple parameters can be added to filter the referenced tracks: album, albumartist, artist, composer, date, genre, performer, and max-age.
• local:directory?type=date: References to directories grouping tracks by date and album. Dates are transformed according to the optional parameter FORMAT which default to %Y-%m-%d. The URIs of the references start with local:directory?date=.
• local:directory?type=genre: References to directories named after genres found among all tracks. Their URIs start with local:directory?genre=.
• local:directory?type=album: References to all albums.
• local:directory?type=album&PARAM=VALUE: References to directories grouping tracks matching the given criteria. PARAM must be one of albumartist, artist, composer, date, genre, performer, max-age. The referenced directories group the selected tracks by album; Their URIs start with local:directory?PARAM=VALUE&type=track&album=local:album:.
• local:directory?type=artist: References to all artists.
• local:directory?type=artist&role=ROLE: References to directories with URIs local:directory?ROLE=URI where URI varies among all URIs starting with local:artist build from all tracks tag corresponding to ROLE. ROLE is one of albumartist, artist, composer, or performer.
• local:directory?album=URI: A reference to a directory grouping the tracks of the album with given URI. Its URI starts with local:directory?album=URI&type=track.
• local:directory?albumartist=URI: References to directories grouping tracks whose albumartist tag has given URI. The referenced directories group the selected tracks by album; Their URIs start with local:directory?albumartist=URI&type=track&album=local:album:.
• local:directory?artist=URI: References to directories grouping tracks whose artist has given URI. The referenced directories group the selected tracks by album; Their URIs start with local:directory?artist=URI&type=track&album=local:album:.
• local:directory?composer=URI: References to directories grouping tracks whose composer has given URI. The referenced directories group the selected tracks by album; Their URIs start with local:directory?composer=URI&type=track&album=local:album:.
• local:directory?date=DATE: References to directories grouping tracks whose date match DATE. The referenced directories group the selected tracks by album; Their URIs start with local:directory?date=DATE&type=track&album=local:album:. The match is to be interpreted as in a LIKE SQL statement.
• local:directory?genre=GENRE: References to directories grouping tracks whose genre is GENRE. The referenced directories group the selected tracks by album; Their URIs start with local:directory?genre=GENRE&type=track&album=local:album:.
• local:directory?performer=URI: References to directories grouping tracks whose performer has given URI. The referenced directories group the selected tracks by album; Their URIs start with local:directory?performer=URI&type=track&album=local:album:.
• local:directory?max-age=SECONDS: References to directories grouping tracks whose "last modified" date is newer than SECONDS seconds. The referenced directories group the selected tracks by album; Their URIs start with local:directory?max-age=SECONDS&type=track&album=local:album:.
