Hi all,

I can now connect to my DLNA libraries using MBC 16.0.81, but the background loading seems to miss most of the files of somes DLNA servers.
* Library 1 :
  -> It is located on the same PC where MC is installed.
  -> Server is Twonky Media v 6.0.32
  -> Twonky logs displays 23982 audio files, 30 images and 5 videos.
  -> MC 16.0.81displays 23974 audio files, 30 images and 5 videos.
  -> Result : nearly 100% OK.

* Library 2 :
  -> It is located on a QNAP NAS, running Twonky server v5.1.6, connected to the PC with a gigabit ethernet link.
  -> Twonky logs displays 23743 audio files, 4701 images and 34 videos
  -> MC 16.0.81 displays 180 audio files, 37 images and 34 videos.
  -> most of audio files and images are not recovered.

Anyone with the same issue ?

Is it linked to the version of twonky I use on the NAS ?

Any workaround ?

Thanks for your help.

[bob]

That's pretty weird.
We ask for the files in groups of 1000  and ask for audio, images and video separately.
Is there perhaps a speed difference in the 2 setups? Maybe the second one is timing out on the replies. Since we ask for all of the information on the items that the server wants to supply, it could be that stresses out the server somehow.

[laurent69]

yes, it's true that the NAS is around 2-3 times slower than the PC when serving audio files.

but applications like plug player manage that speed difference : it takes around 10 secondes to load the 1850 albums list with my iphone and plugplayer.

are there any parameters in MC for this purpose ?

[bob]

Plugplayer doesn't load the remote library, it browses it.
Because of the way MC is structured we ask for the whole remote library (in chunks) and load it in the background. Once the library is loaded, it doesn't need to be loaded again, changes are merged in the background.
Presently the timeout isn't adjustable and is 1 minute / 1000 requested files.
I'll change the logic and get you a build to test. Check your PM later today.

thanks for the help.
It if can help, here are some logs when I connect to the local library (works well).

[laurent69]

and the same with the DLNA library located on NAS with only 229 audio files found, on this sample

each time I refresh (F5) the Library, the number of audio files recovered slighty changes but remain between 200 and 300.

PM'd you with a test build...

[laurent69]

thanks for the build. No changes as far as I've seen.

but this the NAS, still 251 files recovered among which 180 are audio files

in the log, I was not able to recover the number of files displayed, but identified that it seems to load a single piece of 1024 files.

[bob]

The 1024 isn't really significant. It's not referring to the number of files being loaded from the NAS. It seems to me that the NAS isn't working properly with the search requests. I assume you checked for a firmware update??

[laurent69]

I'm afraid you're right : Twonky Server 5.1.6 has a bad reputation ....
