Cover Art Resolution

Post by Willems » Wed Aug 13, 2014 2:05 pm

Hello,

I am using Twonkyserver as my platform for streaming media in my house and it works like a charm, currently I am experiencing only one point which is less than it should be.

The cover art which is shown using Twonkyserver is a very low resolution and gets very grainy when playing music content. For browsing purposes it is OK however when playing it is much too low. I would like to increase the Thumbnail size to at least 500 x 500 and 800 x 800 when possible. Is there a possibility to do this? And how do I change this?

Thank you in advance,

Willems

What version of twonky are you using?
What clients are you streaming to?

I am using Twonkyserver 7.3 and the client I am using most is the Marantz NA8005 through the Marantz Remote App as DMC. However browsing the server using Windows 8.1 Enteprrise also shows that the thumbnails are quite low resolution. It would be great if all of them could be larger.

What are you using to browse with, IE to the twonky web interface?
I am using Twonkyserver 7.3 and the client I am using most is the Marantz NA8005 through the Marantz Remote App as DMC.
In the twonky web interface in settings under sharing,
look under Media Receivers, what does the Marantz get detected as for its "Media Receiver Type"
does one these show?

Marantz
Marantz DMP
Marantz NA-11S1
Marantz NA 7004

Also, where is twonky server installed?

The mediaplayer is recognized as Marantz, the iPad using the Marantz Remote App is recognized as a Generic Media Receiver.

All Marantz profiles as far as I a have seen have the same settings.

Regarding the browsing of WIndows 8 I have been using explorer to access the DLNA server. It is listed as one of the available network locations.

If you edit the Marantz.xml

Add this to it, in between the Adaptations and DeviceQuirks sections

Code: Select all

	<Capabilities> 
		<Scaling>
			<Target>JPEGORG</Target>
		</Scaling> 
                <SupportedMediaProfiles>
                        <Profile>AASCALE#JPEGORG</Profile>
                </SupportedMediaProfiles>

Thanks for this solution. I found out that the profile to be changed is actually the one for the iPad which is used as DMC. By using the full resolution the song starts quite slowly. Which I guess why the resolution was lowered in the first place isn't it?

I understand how to change this and what must be done! Thanks! Problem solved.

Your Welcome, glad to hear your on the right track

I suspect, that the original file might be very large in file size, causing the slow load
which might be compounded by the device having to scale it locally
which is probably eating up cpu and ram resources to do that

Here are some other choices that could be made, if needed to tweak it further
The scaling section offers the client the list of choices
you cant control what it picks, but you can limit its choices

<Scaling>
<Target>JPEG1920x1080</Target>
<Target>JPEG640x480</Target>
<Target>JPEG160x160</Target>
<Target>JPEGORG</Target>
</Scaling>
<SupportedMediaProfiles>
<Profile>AASCALE#JPEG640x480</Profile>
</SupportedMediaProfiles>

I just remembered this

Primarily <Scaling> is for Photo media and not music and video
and mostly <SupportedMediaProfiles> is for thumbnails
The key to thumbnails scaling is AASCALE, as it is for albumart, aka thumbnails
but one also must take note of what the client will support

Hi Phil, i am NEW to the forum and try to find some settings in my twonky set up that allow me to view album art in some rare cases where it is not rendered to my streamer (i have a Seagate Central NAS running versin 7.0.14-1 and stream audio to a NAIM device). Where can i find those "receiver" xml files?

@DrPo

I don't know the "Seagate Central NAS"
But they are very similar in that one needs to first get SSH access to the nas
not sure if this article applies to your nas

http://knowledge.seagate.com/articles/e ... uage=en_US

from there one can use WinSCP or Putty to connect via SSH to the nas
as to where Seagate installed it, I have no idea
But, I would first look in /usr/local and maybe its in /usr/local/twonkymedia or twonky something

Hi Phil, thanks for the promt response. i have write access to the config (.ini file) via PUTTY / WINSPC and my first guess would be to try to fiddle around with the settings there to try to solve my issue.Is there a possibility to email you the .ini file in case you have some bright ideas?

@DrPo

The issue isn't with twonkyserver.ini
It is with the client profiles, they are the xml files, which are here /resources/devicedb

Thanks Phil, I suspect so as well and tried to contact the support of my client product but I would appreciate if you could enlighten me: is this a directory on the server (twonky) "machine" or a directory on the client side? if the directory is on the server side (i am at work now so i cannot check as i read your post) then i could potentially try to edit it...

it is on the server
and one would want/need to know what client profile to edit
you can determine this based on what is being assigned to it from the twonky web interface

22/10: Phil, i cannot locate this directory... on my NAS i find 2 twonky directories (twonky & TwonkyData) under root/Data/ however i cannot seem to find the resources directory you mention under either of those...

.. Just to add that i saw your post with details about how to edit those xml files but the (embarassing) truth is that i cannot access the Media Server.. my NAS uses Twonky under an OEM license (apparently) and the only access i have is to the http://<NASip>:9000 page via PUTTY

Hi Phil,

i have access to the [img][/img]twonky server manager page and what helped a lot was to reassign the "receiver types" for [u]both[/u] my streamer [u]an[/u]d iPad to "NAIM streamer" or "SONGBOOK. DS.."... The default for the iPad client was the generic receiver type which was creating problems with resolution.

Now i have the resolution problem under control, i still dont have fully tackled the problem that some album art is not seen on my iPad application.

For exampled i downloaded today a new purchase from a hi res cite with an embedded .png art of 1MB. It does not show up (but it does on windows applications like foobar or on my client if I use an alternative UpnP server like Asset. My twonky version is 7.0.14-1.

I still have not located where the .xml files for those receiver typs reside but if you have some tips on the album art (e.g. if twonky will read first the Folder then the embedded art, if .png vs .jpg makes a difference...) i am all ears

as I understand it, it looks for embedded first, then external, then for folder.jpg
and if none are found it uses a generic thumbnail

This thread has all the changes to the different versions, as things do change
