I am wondering why NAS users have not problem at all with Rune when building the MPD library.
Because they do it the right way:
- they have their music in one single folder (e.g. Music with subfolders for artists and / or albums)
- they take care not to have non music files (beside cover art) in these folders.
- they share this folder with smb/cifs or nfs.
- they mount this folder within Rune Audio, so mpd has easy access to it.
As I wrote before Volumio is working perfect with my harddisk and we should work on it that Rune can do the same, it is very essential!
Again we know that volumio works with your hdd.
As i told you already Rune is not the problem, it is MPD that doesn't like your music library (or some files on your hdd).
The image for your RP1 is old and not updated for a long time.
More recent MPD versions used on RP2/3 and other platforms may be more tolerant to non music files in the library.
With the next version of Rune the RP1 image will also get an update.
MPD scans all files and folders that are mounted to /mnt/MPD/ and tries to find playable music files.
By adding the .mpdignore file you can tweak this behavior, but you have to specify all non music file endings.
If there is really no other way and a separate hdd for your music is no option i would do it this way:
- create two folders on your hdd (e.g. "music" and "data")
- move all music files and folders containing music to the first one.
- move all other files and folders to "data"
- save a file called .mpdignore in the "data" folder (it should contain the character *)
Do not forget the preceding dot in the filename!
