Music player and server for ownCloud and Nextcloud. Shows audio files stored in your cloud categorized by artists and albums. Supports mp3, and depending on the browser, many other audio formats too. Supports shuffle play and playlists. The Music app also allows serving audio files from your cloud to external applications which are compatible either with Ampache or Subsonic.

Note: The audio formats supported vary depending on the browser. Most recent versions of Chrome, Firefox and Edge should be able to play all the formats listed above. All browsers should be able to play at least the MP3 files.
The modern web browsers ship with a wide variety of built-in audio codecs which can be used directly via the standard HTML5 audio API. Still, there is no browser which could natively play all the formats listed above. For those formats not supported natively, the Music app utilizes the Aurora.js javascript library which is able to play most of the formats listed above, excluding only the OGG containers. On the other hand, Aurora.js may not be able to play all the individual files of the supported formats and is very limited in features (no seeking, no adjusting of playback speed).
Note: In order to be playable in the Music app, the file type has to be mapped to a MIME type audio/* on your cloud instance. Neither ownCloud nor Nextcloud has these mappings by default for the file types AAC, AIFF, AU, or CAF. To add these mappings, run:
./occ music:register-mime-types
Normally, the Music app detects any new audio files in the filesystem on application start and scans metadata from those to its database tables when the user clicks the prompt. The Music app also detects file removals and modifications on the background and makes the required database changes automatically.
If the database would somehow get corrupted, the user can force it to be rebuilt from scratch by opening the Settings (at the bottom of the left pane) and clicking the option "Reset music collection".
If preferred, it is also possible to use the command line tool for the database maintenance as described below. This may be quicker than scanning via the web UI in case of large music library, and optionally allows targeting more than one user at once.
Following commands are available(see script occ in your ownCloud root folder):
Scan all audio files not already indexed in the database. Extract metadata from those and insert it to the database. Target either specified user(s) or user group(s) or all users.
./occ music:scan USERNAME1 USERNAME2 ...
./occ music:scan --group=USERGROUP1 --group==USERGROUP2 ...
./occ music:scan --all
All the above commands can be combined with the --debug switch, which enables debug output and shows the memory usage of each scan step.
You can also supply the option --rescan to scan also the files which are already part of the collection. This might be necessary, if some file update has been missed by the app because of some bug or because the admin has temporarily disabled the app.
Lastly, you can give option --clean-obsolete to make the process check all the previously scanned files, and clean up those which are no longer found. Again, this is usually handled automatically, but manually running the command could be necessary on some special cases.
Reset all data stored to the music database. Target either specified user(s) or user group(s) or all users.
Warning: This command will erase user-created data! It will remove all playlists as playlists are linked against the track metadata.
./occ music:reset-database USERNAME1 USERNAME2 ...
./occ music:reset-database --group=USERGROUP1 --group==USERGROUP2 ...
./occ music:reset-database --all
Music app caches some results for performance reasons. Normally, there should be no reason to reset this cache manually, but it might be desirable e.g. when running performance tests. Target either specified user(s) or user group(s) or all users.
./occ music:reset-cache USERNAME1 USERNAME2 ...
./occ music:reset-cache --group=USERGROUP1 --group==USERGROUP2 ...
./occ music:reset-cache --all
The URL you need to connect with an Ampache-compatible player is listed in the settings and looks like this:
https://cloud.domain.org/index.php/apps/music/ampache
This is the common path. Most clients append the last part (/server/xml.server.php) automatically. If you have connection problems, try the longer version of the URL with the /server/xml.server.php appended.
Similarly, the URL used to connect with a Subsonic-compatible player is listed in the settings and looks like this:
https://cloud.domain.org/index.php/apps/music/subsonic
Ampache and Subsonic don't use your ownCloud password for authentication. Instead, you need to use a specifically generated APIKEY with them. The APIKEY is generated through the Music app settings accessible from the link at the bottom of the left pane within the app. The generated APIKEY is shown upon creation but it is impossible to retrieve it at later time. If you forget or misplace the key, you can always delete it and generate a new one.
When you create the APIKEY, the application shows also the username you should use on your Ampache/Subsonic client. Typically, this is your ownCloud login name but it may also be an UUID in case you have set up LDAP authentication.
The Music app can be installed using the App Management available on the web UI of ownCloud or Nextcloud for the admin user.
After installation, you may want to select a specific sub-folder containing your music files through the settings of the application. This can be useful to prevent unwanted audio files to be included in the music library.
The application's scalability for large music collections has gradually improved as new versions have been released. Still, if the collection is large enough, the application may fail to load. The maximum number of tracks supported depends on your server but should be more than 50'000. Also, when there are tens of thousands of tracks, you may notice slow down of the web UI.
There exist partial translations for the Music app for many languages, but most of them are very much incomplete. In the past, the application was translated at https://www.transifex.com/owncloud-org/owncloud/ and the resource still exists there. However, large majority of the strings used in the app have not been picked by Transifex for many years now, and hence the translations from Transifex cannot be actually used. The root cause is disparity in the localization mechanisms used in the Music app and on ownCloud in general, and bridging the gap would require some support from ownCloud core team. This is probably never going to happen, see https://central.owncloud.org/t/owncloud-music-app-translations/14881. For now, you may contribute translations as normal pull requests, by following the instructions from owncloud#671 (comment).
The Music app may be unable to extract metadata of the files residing on a SMB share. This is because, on some system configurations, it is not possible to use fseek() function to seek within the remote files on the SMB share. The getID3 library used for metadata extraction depends on fseek() and will fail on such systems. If the metadata extraction fails, the Music app falls back to deducing the track names from the file names and the album names from the folder names. Whether or not the problem exists on a system, may depend on the details of the SMB support library on the host computer and the remote computer providing the share.
All the frontend javascript sources of the Music app, including the used vendor libraries, are bundled into a single file for deployment using webpack. This bundle file is dist/webpack.app.js. Similarly, all the style files of the Music app are bundled into dist/webpack.app.css. Downloading the vendor libraries and generating these bundles requires the npm utility, and happens by running:
cd build
npm install --deps
npm run build
The command above builds the minified production version of the bundle. To build the development version, use
npm run build-dev
To automatically regenerate the development mode bundles whenever the source .js/.css files change, use
npm run watch
To build the release zip package, run the following commands. This requires the make and zip command line utilities.
cd build
make release
To install test dependencies, run the following command on the root level of the project:
composer install
composer run-script analyze
composer run-script unit-tests
The integration tests require the music app to be installed under the apps folder of an ownCloud or Nextcloud installation. The following steps assume that the cloud installation in question has not been taken into use yet, e.g. it's a fresh clone from github.
cd ../.. # owncloud/nextcloud core
./occ maintenance:install --admin-user admin --admin-pass admin --database sqlite
./occ app:enable music
cd apps/music
composer run-script integration-tests
cd tests
cp behat.yml.dist behat.yml
# add cloud URL and credentials for Ampache and Subsonic APIs to behat.yml
../vendor/bin/behat
For the acceptance tests, you need to upload all the tracks from the following zip file to your cloud instance: https://github.com/paulijar/music/files/2364060/testcontent.zip
The translatable strings are extracted from the front-end files of the Music app proper using the angular-gettext module. This is installed among other dependencies with npm.
In addition, there are some translatable strings within the back-end code and in the front-end files for the embedded Files player and for the Nextcloud Dashboard widget. These are handled using the perl script l10n/l10n.pl. In addition to the perl interpreter, this script requires the module Locale::PO (can be installed with CPAN) and the xgettext tool. On Linux, the latter should be available with apt-get install gettext or similar. On Windows, this needs to be installed manually and the executable must be added to the PATH; at least the version 0.22.5 from https://github.com/vslavik/gettext-tools-windows/releases seems to work well.
When the tools are setup correctly, all the strings can be extracted from the source codes to l10n/templates/music.pot with the command:
cd build
make l10n-extract
The music.pot file can then be used to update the language-specific translation file (l10n/*/music.po) as described in owncloud#671 (comment).
Once the translations have been updated in the .po files, we need to generate the final source files used to build the Music application. This, again, uses both angular-gettext and l10n/l10n.pl. For this, execute
cd build
make l10n-clone
make l10n-compile
The step l10n-clone above makes copies of some translations to different language codes. This is needed because ownCloud and Nextcloud use slightly different language codes in some cases. Furthermore, the clouds may support multiple versions of the same language but the Music app currently has identical translation for each of them.
The Music app back-end implements the Shiva API except the resources /artists/<int:artist_id>/shows, /tracks/<int:track_id>/lyrics and the meta resources. You can use this API under https://own.cloud.example.org/index.php/apps/music/api/.
However, the front-end of the Music app nowadays doesn't use any part of the Shiva API. Instead, the following proprietary REST endpoints are used:
/api/log/api/prepare_collection/api/collection/api/folders/api/genres/api/file/{fileId}/api/file/{fileId}/download/api/file/{fileId}/path/api/file/{fileId}/info/api/file/{fileId}/details/api/scanstate/api/scan/api/resetscanned/api/cover/{hash}/api/artist/{artistId}/cover/api/artist/{artistId}/details/api/artist/{artistId}/similar/api/album/{albumId}/cover/api/album/{albumId}/details/api/share/{token}/{fileId}/info/api/share/{token}/{fileId}/parse- Playlist API at
/api/playlists/* - Radio API at
/api/radio/* - Podcast API at
/api/podcasts/* - Settings API at
/api/settings/*
To connect external client applications, partial implementations of the following APIs are available:
- Ampache XML API at
/ampache/server/xml.server.php - Ampache JSON API at
/ampache/server/json.server.php - Subsonic API at
/subsonic/rest/{method}
Allows to log a message to ownCloud defined log system.
POST /api/log
Parameters:
{
"message": "The message to log"
}
Response:
{

}
Returns all artists with nested albums and each album with nested tracks. Each track carries a file ID which can be used to obtain the file path with /api/file/{fileId}/path. The front-end converts the path into playable WebDAV link like this: OC.linkToRemoteBase('webdav') + path.
