Cover art not displayed

[jeanloop]

Hi,

i have recently installed ums on my ubuntu server (a headless Precise) and got it mostly working by now. I am accessing my music collection using my android phone and browsing and playback works fine.

Something i couldn't get to work is cover art. When browsing only the default icon is shown for all folders (that blue movie slide icon). During playback the renderer says there is no cover available.

I have already searched the web a lot and read the documentation. I found several config options that i tried. In my UMS.conf I have these:

thumbnails = true
image_thumbnails = true
audio_thumbnails_method = 1

but it didn't help.

I also put the server logger in ALL mode and got a lot of output. I can see when the thumbnail gets requested, but from the file size i can tell it is only the default icon that gets sent to the client (i requested the same URI using the browser and looked at the HTTP headers).

Code: Select all

I wonder what "discover X refresh forced: false" means.

All music files are FLAC and get transcoded to WAV. The logs say, this is done by FFMPEG (BTW: I am using only system libraries).

Am i missing some configuration option to really enable cover downloads?
What else can i try to get this to work?

Thanks a lot for your help (and of course for this great piece of software!),
