No artwork
Hi,

I am trying MinimServer with my Naim NDX and it works great. In particular, the FLAC to WAV transcoding has made a really significant sound quality improvement.

However, none of my artwork shows up in n-Stream. It works under every other uPnP I have tried. They are all folder.jpg. I am running MinimServer on a Mac and pulling off the files from a ReadyNAS over a wired network.

I am getting the following errors in the log:

TTPService: unexpected request GET /minimserver/HiRes2/The%2520Who/Who's%2520Next%2520(1971)(24%25ef%2580%25a288.2%25202010%2520SHM-SACD)/folder.jpg HTTP/1.1
HTTPService: sending response HTTP/1.1 404 Not Found: Unable to read data from requested resource

For pages and pages. The files seem to appear and play OK.

Any assistance would greatly be appreciated

Thanks,
Wayne

It looks like the control point isn't handling encoded URL characters correctly.

Please can you do the folllowing:

1) Start MinimServer and let it finish initializing
2) From the minim icon, select 'Show log'
3) In the log window, set the logging level to Trace
4) Leave the log window open
5) Browse into a container (small if possible) whose contents include artwork
6) You should see some messages appear in the log window
7) Use the 'Save as' button to save the log output to a file
8) Set the logging level back to Info and close the log window
9) Zip the saved log file and attach it to a post here

The log output should show me exactly what MinimServer is sending to the control point for album art URIs.

Thanks very much! This shows the control point bug very clearly. For example, MinimServer sends the control point the following:

<upnp:albumArtURI>http://192.168.0.12:9790/minimserver/HiRes2/Diana%20Krall/Quiet%20Nights%20(2009)%20%5bVerve%5d/01%20-%20Where%20Or%20When.flac/$!picture-397-70568.jpg</upnp:albumArtURI>

in which some space characters have been URL-encoded as %20. The control point then sends MinimServer the following:

GET /minimserver/HiRes2/Diana%2520Krall/Quiet%2520Nights%2520(2009)%2520%255bVerve%255d/12%2520-%2520Everytime%2520We%2520Say%2520Goodbye.flac/$!picture-409-70568.jpg HTTP/1.1

As you can see, each %20 has been changed by the control point to %2520. (The %25 is the URL-encoded representation of %, so these characters are now double-encoded.) The control point should be returning the URL in its original (already encoded) form, and should not be modifying it in this way.

Which control point are you using?

Naim n-Stream. Seemed to work with Twonky, Asset etc.

Thanks for investigating for me

The reason it works with Twonky and Asset is that they don't send escaped characters in URLs, so this bug in n-Stream wouldn't show up with those servers.

I'm not quite sure what the next step should be. Would you be willing to report this bug to Naim?

RE: No artwork
Sure. Let me try a different player first, just in case there is something specific to my setup

Thanks

RE: No artwork
Good evening,

I have just found this thread and I can confirm that this indeed seem to be a Naim specific problem. I have tried the latest MinimServer version with a UnitiQute (3.17), N-Stream 3.2 on an Ipad 2 and have the same error messages in the Minimserver logfiles.

With Twonky Server I have never experienced this issue.

Keep up the great work!

Kind regards

Hi,

I tried Kinsky which did manage to show the artwork. I'll send the Naim support e-mail address a bug report

Thanks
