Hi all.
Since I got all my cd's on the Twonky for RaspBerry PI, it seems that sometimes Artist Covers for the albums are found, and sometimes not ?
F.ex after the latest rebuild my Alphaville album does not have an artist cover, but the album cover is fine, the artist cover was there before the rebuild.
Many of the Artist Covers are now grey.
When browsing the artist, all albums have covers and are ok.
It started after I had to reset the content database last night, it was mixing album covers up between artists, this is now ok, but missing a lot of the artist covers from my local content.
Is this also "random" for others using DLNA ?

Dear Weebyx,
I have tried the same solution - using the Raspberry Pi as a DLNA-Server 2 years ago. I even presented the idea to B&O while we meet in Singapore. I wrote a script to point the raspberry pi to my music collection on the music folder in my synology NAS, directly after rebooting (even after power loss). Sadly, it worked for small music collections only. If the music collection gets bigger you will face some serious troubles. There is a significant dalay while serving as a main DLNA to the BS-Moment. This delay from the Raspberry Pi begann to corupt the database in the twonky-server. Missing or scrambled cover-tiles (artists, album) - like you described before. The Moment is checking the content from the DLNA-Server constantly. If some content is changing periodically , you will have a corrupted database on the BS Moment as well. In my case the delay doubled, because the Raspberry needed to "wait" for the synology NAS.
In the end- because of these problems - I decided to let the idea (using the raspi) go. I wanted to overcome the missing Twonky-support for Synology devices. I even anounced this solution in the "one month with the BS Moment" thread and afterwards I never delivered a "manual" for other users. You finally did it. Thank you! I am affraid, that the raspberry Pi is not fast enough to work as Twonky-DLNA-Server constantly.
I really hope you could overcome the delay issue and the corrupted database. I decided to buy a mac mini, for the purpose of serving the Moment only. The missing/switched covers are mostly caused by the Raspberry Pi - not by the Moment
With the new recent 2.x OS-Version on the Moment, the DLNA abilities of the Moment to "talk" with the NAS are now much better. But there are still some glitches with larger Music collections. As a beta-tester for the BS Moment, I can assure you, that B&O is knowing these issues and they are working on a solution for big databases right now. There will be a sollution in the upcoming updates.
Cheers Beroli
Hi and thanks for the response.
My collection is not that big, 29 albums, thats it. I don't think the missing Artist Cover has something to do with the raspberry. All albums covers are perfect served from the PI(needed a rebuild to fix some mixed albums, but I take that as I was adding content while the Moment was harvesting), so no problem there.
The missing artist covers, are the first level in the "Collection" tab, I think these images are taken from Gracenote or somewhere else, and maybe the search delivers different results to the Moment, I don't know the Gracenote API, but that might be the issue, I also have a missing Artist Cover for 1 of my Deezer albums.
The PI are set at 0-1% CPU usage, and the WiFi is strong and with no issues.
I guess the issue is how the Moment finds covers for artists and not the album cover themselves, they are located in the music files, and works fine.
I have while writing this, tested by pointing the Moment to the Twonky on my MacBook Pro, that has the exact same content as the PI, the result are the same. Missing cover artists for som of the DLNA content.
I have just added the same album from Deezer, and then the Artist Cover shows up immediately, so there must be something regarding how these artist covers are found that are different in terms of Deezer and DLNA.
Hi Weebyx,
Yes indeed, there are differences between the artist tiles in deezer and in the DLNA collection. You can not compare the ways how Deezer is processed, to the ways of the DLNA-content. The DLNA content needs to be vetted, because some users have no or bad id-tags. Some implemented to huge images in the tracks, some of them have no id-tags at all. Therefore B&O implemented a process to ork around these issues caused by the users. But I agree, on a well tagged collection, these processes do more harm and they cause unnecessary workload for the Moment.
Regarding the tiles. Sometimes you get different tiles for the same artist (local (DLNA)/Deezer), if they are available. In the new version the artist tiles are added randomly, it should fill up over time.
I did not meant, that the CPU from the raspberry is to weak, I meant that the processes from the twonky-server on the raspberry pi are to unstable. Sometimes, it works perfect and after a while the content is going awol - and if the Moment tries to read exactly in these moments, your database on the Moment will be harmed. There are some processes on the pi, which are working against the purpose of a dlna server.
Regarding the Wifi. I wanted to recommend it to your very good manual. Wifi is not the best for a DLNA-Server. Having a ethernet-connection works much better, especially regarding a stable stream for uncompressed file-formats. Even the raspberry works much better, with a ethernet connection.

regarding the missing artist covers of DLNA content. Sometimes it is a issue of rights (laws). Some artist are against any publishing of their pictures, some of them restricting the ways of their usage. Therefore some artist-tiles will be shown for Deezer and the same artist will be missing for the local content, because of these restrictions. I suppose Deezer/Gracenote is paying for these rights. Therefore B&O could be sued for infringing these rights, if they would provide these tiles by default.

Yes, I know ethernet is better that WiFi, but in my apartment, it is very hard to get cables for wired connection up and running. I could connect the PI directly to my wifi router, but it will still be wifi between router to Moment.
I have had zero problems with everything being WiFi for now, so I see no need to try to get them wired :)

Unfortunately, there are a boatload of known issues, if the Moment is pointed to a DLNA-Server over Wifi. It is, of course, your choice to see no need to wire. I just recommended the obvious. 😉

Could you give examples of the boatload of issues ?
Apart from the missing Artist Cover, which I don't think has anything to do with my DLNA/PI, I have nothing that does not work. No dropouts when playing music, very fast harvesting of content, all my albums has covers..
Weebyx: Could you give examples of the boatload of issues ?
It seems I have offended you somehow? Your DLNA-collection is very small right now. let's talk again when you hit more than 20-30 thousand tracks. If you are interested in the common issues of a wifi over a ethernet connection, I recommed to read some B&O service manuals offered here in the forum. The quality of Wifi (transfer rate) is depending strongly on the surrounding area (wires, building structure, other wifi networks, router...). If you are fine with your wifi, I am happy for you. If your happy with the raspberry, then it is fine for me as well. Been there, done that - sadly did not work on longterm perspective with bigger databases.
Regarding the artist tiles, you got the answers already twice. I've never said, that the main issue is your wifi. You wrote your album and artist covers were mixed up as well, thats why I gave you my 50 cents. Now I am really regretting answering your question in the first place. If I am right, you own the BS-Moment for a very short time now. Therefore I thought you were asking for help. Maybe next time I should just write "please use the search"

Tou have not offended me, I was just asking a question on what the issues was/could be, since I have not had any of them. Simple as that, don't take it to personal..
You are correct, my database i small now, with approx 800 songs or so, just the old cd's I often listens to. Thought it would be cool to have them on the DLNA server to listen to in lossless, nothing more than that.
I follow here a lot, and don't seem to remember a post where a PI was used as DLNA. Sorry if I missed it.
I was asking for help with information about the Artist Covers, and I got the answers I was after, I was just a bit confused about the problems you said there could be with WiFi, since I have not experienced them myself. But this might be because of the small collection, maybe I will come to the same conclusion as you later on.
I had 2 albums in the beginning when I was copying data to the DLNA, where the album had a different cover than it should have, but the Moment started acting up in general, loosing Deezer albums and so on, so did a factory reset, and has not had any isses other than the missing Artist Covers.
But never mind, I did not want this to be a big discussion, and especially not if you think I just dismiss your advice. Don't know why you regret answering the question ?
Have a nice day.
I had the feeling of beeing dismissed. Maybe I am too thin skinned. Don't get me wrong. I really appreciate your efforts regarding the raspberry Pi and I really liked your recent manual. I tried it with the raspberry pi 2 B, maybe the latest Pi will work better. Therefore I am looking forward to read about your progress.

You were not dismissed at all :)
To your defence, I have just tried a thing, I have connected the PI to my WiFi router via cable, even though my Mac is still on WiFi, the copy speed to the PI using FileZilla has increased by times 8 or 10 !!
So the WiFi in the PI is probably not the best :)
It will stay connected by cable...
The difference between 2 and 3 is quite large.
****
The Raspberry Pi 2 has a quad-core 900MHz CPU, the Pi 3 a quad-core 1.2GHz one. Both have 1GB RAM and both use a fourth-generation VideoCore CPU.
From a glance you could dismiss this as a connectivity upgrade, but the performance boost is big. Very big.
First, while the CPU only gains 300MHz, it also updates its architecture from a Cortex-A7 set to a Cortex-A53 one. This is an architecture boost from 32-bit to 64-bit, and gets you better performance for your clock speed.
Next up, the GPU. Both are VideoCore IV chipsets, but where the Pi 2 is clocked at 250MHz, this new one is 400MHz.
While they’re both designed to deliver 1080p video rather than 4K, this means the graphics chip has been scaled up with the CPU. The Raspberry Pi Foundation knows what it’s doing.
Perhaps the least well-documented upgrade is the RAM. Both models have 1GB, both are forms of DDR2. But where the Raspberry Pi 2 has 450MHz, RAM, the Pi 3 has 900MHz RAM.

Maybe the 3 is better, I need to try to use it over time, and build a larger collection :) I will keep you posted...
