Scan Media Library Task performs remote metadata lookups despite “Never” setting

[denzoid 60]

Problem

I'm running Emby Server 4.9.5.0 on Unraid.

My Music library is configured with:

• After initial import, automatically refresh metadata from the internet: Never

• Metadata downloaders: Discogs, MusicBrainz, TheAudioDB

• Same Image fetchers are enabled.

When I manually run Scan Media  from Scheduled Tasks, Emby spends a significant amount of time identifying/processing music and makes external metadata requests.

The attached log shows Emby making requests to:

• TheAudioDB

• Discogs

• Fanart.tv

• MusicBrainz

For example:

DiscogsArtistImageProvider.GetImages

and:

Emby.Providers.Manager.MetadataService.ExecuteRemoteProviders

Discogs is also returning HTTP 429 TooManyRequests because of the volume of requests.

My understanding is that a normal Scan Media Library should detect new/changed files and should not perform a remote metadata refresh when the library is set to Never after the initial import.

Is this expected behavior in 4.9.5.0, or is there a setting I'm missing?

If this is a bug, is there a known workaround or fix?

I'll attach the relevant embyserver.txt log showing the requests.

I believe that setting applies to changing existing metadata.  The server is going to look to fill in missing metadata continuously.

It seems to spend 15-20 minutes every scan looking for the same thing, is there anyway to disable this or any workaround?

It doesn’t actually look to fill in anything continuously after the initial import.

 Something is causing them to be refreshed, probably a media file change, nfo file change, image file change, etc. I see you use strm files do also if the contents change. 
 

Whenever it refreshes it goes through the full chain of all your embedded providers.
