Serviio symlink behaviour and DB update issue

Hi

I'm relatively new to Serviio

I've switched over from TM because I needed the transcoding abilities and because I need to use playlists for my audio files.
My Serviio (1.1_b10) is running on a TS-210 QNAP NAS, with java 7.

I've modified the profiles to suit my DLNA players to audio only, since transcoding a movie file on an ARM CPU won't work in this life or the next.

I've been updating my audio file collection, adding EAC flac ripped CD's from my collection. As it so happens there are quite some double files in my audio library (compilations, original albums...)
So I got the idea to remove the double files (if identical) and replace them with a symlink, so I could play an album entirely without having the same song all over the place in my library.
I'll probably need a script or so to get all this done reliably, however that is not the issue.
My problem is that the symlink is found correctly, but the DB entry is added using the metadata of the pointed to file. So in the end my symlink never shows up in the album where I want it to be in, but in the album of the linked to file.

as an example I've deleted and recreated a symlink for Guns N' Roses Welcome to the Jungle and forced a library refresh
- here is the grepped logentry :

In this example I get two entries of welcome to the jungle in the greatest hits album, and none in the appetite for destruction album
Is there any way to force it to show up in the correct dir ?


My second problem is that the DLNA server is stopped each time a library refresh is performed, which is kind of a nuisance since the 'streaming' aspect of Serviio seems the most important function IIRC.
It automatically comes up after a while, but if there was a stream being delivered, my renderers choke on it evidently.
Is this 'normal' behaviour ?

[zip]

Yes, it uses the absolute path to detect whether file is already in the DB. TBH, I'm reluctant to change this because it might break other things that users now use.

There is not much options to give higher priority to tasks in Java, but you could increase the auto scan wait period in the console.

thanks for the reply

So there seems no other way to get the links to appear in the right dir... bummer. I don't know if there is a way to 'add metadata' to a symlink.
Maybe provide the either the dir in which the link is found or the absolute path as an option to choose from in config ?

About the update issue, I've already resorted to an external script which monitors the directory and directs a DB refresh action to serviio. Normally once the library is made, not many changes are being done afterwards.
