Many rooms in our house have an UPnP capable internet radio device, and I'm using Mediatomb to distribute music and radio to them.
Mediatomb automatically categorizes music files into different virtual folders:
UPnP directory root ├ Audio │ ├ Albums │ ├ All - full name │ ├ All Audio │ ├ Artists │ ├ Genres │ └ Year ├ PC Directory └ Photos
This is fine for music albums, but not for radio plays, podcasts, single tracks I don't have the full album for and kid's tales.
Luckily mediatomb allows one to completely customize how those virtual folders are setup.
Plan
Files for our kids fall in two categories: Music and tales/stories. Thus beside the "Audio" and "Photos" folder, there shall be a "Kid's Music" and "Kid's Stories" folder. They should not be indexed in the Audio folder.
I've got Podcasts and adult radio plays as well, and they should also not be in the Audio folder, but in their own ones.
Finally, single songs shall be put into "Audio/Singles" without any futher indexing.
UPnP directory root ├ Audio │ ├ Albums │ ├ All - full name │ ├ All Audio │ ├ Artists │ ├ Genres │ ├ Singles │ └ Year ├ Kid's Music ├ Kid's Stories ├ Podcasts ├ PC Directory ├ Radio plays └ Photos
I've already sorted them in the real directories that way:
$ ls -1 /var/spool/music Albums Singles Radio plays Kid's music Kid's tales Podcasts
With that, I only have to configure mediatomb to act a bit differently depending on the folder the audio file is in.
Mediatomb configuration
At first mediatomb has to use a custom import script. The documentation tells us that we have to use a virtual layout of type js, and can configure the import script there:
<virtual-layout type="js"> <import-script>/etc/mediatomb/import-cweiske.js</import-script> </virtual-layout>
import-cweiske.js is a copy of /usr/share/mediatomb/js/import.js with some small changes. The scripting docs helped here:
$ diff -u /usr/share/mediatomb/js/import.js /etc/mediatomb/import-cweiske.js --- /usr/share/mediatomb/js/import.js 2012-06-09 20:59:50.000000000 +0200 +++ /etc/mediatomb/import-cweiske.js 2015-04-09 21:56:33.000000000 +0200 @@ -108,6 +108,28 @@ // comment the following line out if you uncomment the stuff above :) var track = ''; + if (obj.location.indexOf('/Albums/') === -1) { + //no Music Album, so keep them in separate folders + if (obj.location.indexOf('/Singles/') !== -1) { + chain = new Array('Audio', 'Singles'); + obj.title = title; + addCdsObject(obj, createContainerChain(chain)); + } else if (obj.location.indexOf('/Radio plays/') !== -1) { + chain = new Array('Radio plays', album); + obj.title = track + title; + addCdsObject(obj, createContainerChain(chain), UPNP_CLASS_CONTAINER_MUSIC_ALBUM); + } else if (obj.location.indexOf("/Kid's stories/") !== -1) { + chain = new Array("Kid's stories", album); + obj.title = track + title; + addCdsObject(obj, createContainerChain(chain), UPNP_CLASS_CONTAINER_MUSIC_ALBUM); + } else if (obj.location.indexOf("/Kid's music/") !== -1) { + chain = new Array("Kid's music", artist, album); + obj.title = track + title; + addCdsObject(obj, createContainerChain(chain), UPNP_CLASS_CONTAINER_MUSIC_ALBUM); + } + return; + } + var chain = new Array('Audio', 'All Audio'); obj.title = title; addCdsObject(obj, createContainerChain(chain));
The adjustments to the addAudio function do the following:
- If the file's location (full path) does not contain "Albums", the special handling starts.
- If the file's location contains "Singles", the track gets put into the Audio/Singles/ folder. This folder is a normal folder, which means it gets sorted alphabetically.
- If the file's location contains "Radio plays", the track gets put into Radio plays/$album name/. This folder is a music album folder which means tracks get sorted by the track number and not alphabetically.
- .. and so on
- At the end, we simply return from the function, which prevents the normal virtual folder handling for those files.
