Also supported are players that run Kodi:

What is mpd?

Mpd is short for music player daemon, a Linux based open source music player. It can be installed on your own hardware, and is also used in a number of commercial network players, mostly high-end.
Mpd combines very well with a Raspberry Pi to create a network music player at a fairly low price. Various standard distributions based on mpd are available to get your started easily, like Volumio and Rune Audio.

Does Rigelian support album and artist artwork?

The quality of the cover art depends on the type of player you have. For Bryston, Volumio, moOde, Rune Audio and Kodi cover art settings are automatically configured. On other mpd based players cover art can be retrieved in one of the following ways:

  • if your mpd version is at least 0.21, it can serve up an image file that is named cover.jpg or cover.png in the folder of the album or artist. The filenames are hardcoded in mpd and can’t be configured.
  • if your mpd version is at least 0.22, it can serve up artwork that is embedded in the music files. This can put load on the player and is slower than the cover.jpg method.
  • via a http-based connection. The exact settings can be entered per player.

In local artwork can’t be found on the player, Rigelian will look on Discogs and MusicBrainz. Unfortunately the quality of the cover art is not very consistent on these services.

Subscribers can use the cover art assistant (available for albums and artists) to diagnose how cover art is retrieved. It also provided the option to enable / disable sources for cover art. To open it, long-press an album, then select ‘Cover art assistant’.

How can I listen to music on my device?

Rigelian supports connecting to a http audio stream so you can listen to your music on your device. There are a couple of pre-requisites:

  • You need to be using mpd.
  • You need to have a Rigelian subscription.
  • A http output must be configured in mpd.conf, see below.
  • In the player settings in Rigelian, you need to enter the ip-address and port number matching mpd.conf.
  • The encoder must be set to lame, vorbis won’t work.

When all the above pre-requisites are met, a headphone button will appear on the now-playing view. By default this is disabled (greyed out), you can enable it by clicking the button. Once enabled, whenever you start playing something it will play on your device.

Note that due to http buffering there is a 4-5 seconds delay for actions performed in Rigelian.

# An example of a httpd output (built-in HTTP streaming server):
audio_output {          
        type            "httpd"
        name            "My HTTP Stream"        
        encoder         "lame"            # optional, vorbis or lame
        port            "6700"
        bind_to_address ""     # optional, IPv4 or IPv6
        tags            "yes"                   
        quality         "5.0"             # do not define if bitrate is defined
        format          "44100:16:1"

Why are songs removed from the playqueue even when Consume is turned off?

The songs are not removed, but the playqueue of Rigelian only shows the tracks after the currently playing track. You can still go back in the play queue via the back button. This type of display is by design and there are no plans to change this.

Why are some albums shown multiple times?

The proper display of albums requires that the AlbumArtist mp3 tag is used. Here’s an example of what the tagging should look like.

Let’s assume that the following 4 albums are in the collection, and they have to be shown as individual albums:

  • The album ‘Greatest Hits’ by Queen
  • The album ‘Greatest Hits’ by ABBA
  • The compilation album ‘Hits for X-Mas’ with songs from 18 different artists
  • The album ‘A Seat at the Table’ by Solange, where some songs are collaborations with other artists

To achieve this, data is grouped by Album and AlbumArtist, and it will lead to the expected results when the following meta-data is present:

The album ‘Greatest Hits’ by Queen, For all tracks on the album:

  • Album: Greatest Hits
  • Artist: Queen
  • AlbumArtist: Queen (or empty in which case the Artist is used as AlbumArtist)

The album ‘Greatest Hits’ by ABBA, For all tracks on the album:

  • Album: Greatest Hits
  • Artist: ABBA
  • Album Artist: ABBA (or empty in which case the Artist is used as AlbumArtist)

The compilation album ‘Hits for X-Mas’ with songs from 18 different artists, For all tracks on the album:

  • Album: Hits for X-Mas
  • AlbumArtist: Various
  • For each individual track, Artist: Queen, ABBA, Chris Rea, etc.

The album ‘A Seat at the Table’ by Solange, where some songs are collaborations with other artists, for all tracks on the album:

  • Album: A Seat at the Table
  • AlbumArtist: Solange
  • For each individual track, Artist: Solange, Solange feat. Q-Tip, Solange feat. Kelala, etc.

If you have properly organized your music in folder, as an alternative you can use the folder browse view.

Why can’t I use the hardware buttons on my iPhone to control the volume?

Official API’s in iOS only support these keys in combination with music (or anything else) that is playing on your device, not for network music players. Therefor Rigelian doesn’t support this.

Can I control my player from the lock screen?

No, controls on the lock screen only work with music that is playing on your device. As an alternative Rigelian offers a today widget which is accessible through a swipe-right on the lock screen.

Does Rigelian support streaming from cloud services?

Subscribers can browse through radio stations provided by Shoutcast. Support for other cloud services like Tidal and Qobuz is not available as there is no consistent way in which this is supported by mpd.

Why does Rigelian use a subscription model?

To support the continued development of Rigelian, which includes staying up-to-date with future developments on mpd and iOS.

Will there be an Android version of Rigelian?


Why is Rigelian called Rigelian?

Rigelian is named after the ‘Rigelian Empire’ from the Nintendo Fire Emblem game.
