low resolution mp3 embedded cover art images

Hi-- I'm using Serviio with BubbleUpnP client and everything works fine with the exception of the embedded mp3 artwork is very distorted low resolution being passed to the BubbleUpNp player on samsung nexus 7 and galaxy s2... My original artwork thumbnails are all very good quality 500x500 and above, I checked with Bubble forum and they said the issue may be on server side regarding how you extract and pass the thumb images. Please advise, thanks in advance. - John

Re: low resolution mp3 embedded cover art images

the DLNA spec supports 160x160 thumbnails size max. There is an open ticket to support higher res, for players which can deal with them.

Hi zip,

I'm the BubbleUPnP developper.

After looking at the DIDL sent by serviio for a music item, I found that it only sends a thumbnail 160x160 URI:

  Code:
  <upnp:albumArtURI dlna:profileID="JPEG_TN" >http://192.168.1.14:8895/resource/14880/COVER_IMAGE</upnp:albumArtURI>


Ideally it should also send an URI pointing to the full res image (nothing prevents multiple albumArtURI tags):

  Code:
<upnp:albumArtURI dlna:profileID="JPEG_TN" >http://192.168.1.14:8895/resource/14880/COVER_IMAGE</upnp:albumArtURI>
<upnp:albumArtURI>http://192.168.1.14:8895/path/to/full/res/image</upnp:albumArtURI>


Most Control Points will use the thumbnail image when a thumbnail is required, and the full res image otherwise (Now Playing screens).

Re: low resolution mp3 embedded cover art images

Please add this feature ! Having low res thumbnails while playing audio files is really disappointing.

Thanks in advance.

Re: low resolution mp3 embedded cover art images

Thumbs up. I would also favor higher resolution Album Art.

Are there any updates regarding this topic?

Re: low resolution mp3 embedded cover art images

Although not the way as suggested above. It'll serve just one thumbnail, either dlna-spec sized or 320x320, depending on the profile.

Re: low resolution mp3 embedded cover art images

Regularly, users complain of low res album art with Serviio in BubbleUPnP.

It would really much simplier if Serviio advertised both the thumbnail image and the full res one and let the Control Point choose.
Or several DLNA thumbnail profiles (JPG_SM, JPG_LRG, etc). Many media servers do this (or just include the full res image).

That would avoid me to point to lengthy instructions to have glorious (HD?) 320x320 covers:

Also think of tablets with super high res screens. 320x320 doesn't really cut it.
Think of the Control Points. Not everyone browse through a TV. That's where the profile system shows its limits.

Re: low resolution mp3 embedded cover art images

I also think that this limitation is frustrating. Users should at at least be given a choice to serve high resolution, or better full resolution thumbs.

Re: low resolution mp3 embedded cover art images

DLNA spec states 160x160. Serviio also stores 320x320 and you can choose that in the profile.

Re: low resolution mp3 embedded cover art images

I just dicovered this brilliant DLNA application und intend to replace the always failing PLEX with it.
Many thanks for it, but of course I eventually stumbled upon the cover resolution issue.

What profile would I have to choose, to get at least the 320/320 resolution?
In Serviio/Status you only can choose specific profiles for various gadgets (none of which applies to my configuration: NAIM Streamer controlled by Bubble UPnP or NAIM app).
Do I have to try them all to find out which one delivers 320/320?

Edit:
Yes, you have to try them all out.
Luckily success came with the (about) 12th attempt -with the 'playstation 4' profile.
Now I am enjoying the "HD" view of my album covers :D


The instructions of 'bubblegum' to edit the 'profiles.xml' are not so easy for me to execute, as I am using the SERVIIO server installed on a QNAP-NAS.
Don't want to dive into Linux...

All the the other servers I use (Twonky, Minim, Plex) have absolutely no problem displaying the cover images in full resolution and I am sorry to say that I am just a bit disappointed about the reluctant attitude of the developper concerning this feature.

Thanks nevertheless for assistance!
