TS 7.3, thumbnail generation seems broken

[Pasha_ZZZ]

1) installing 7.3 over 7.2.6 reset all settings to defaults;
2) creating ffmpeg.location again, point it to ffmpeg bin directory - unsuccessful, there are no thumbnails.

[phibertron]

did you restart the server after you created the ffmpeg.location with the path to ffmpeg?
I didn't run into any issues getting ffmpeg to work for thumbs

If you are using windows or mac, you could just put a copy of ffmpeg in the twonky cgi-bin folder
no need for an ffmpeg.location file when doing that

Yes. Restart server, restart PC, even reinstall Twonky...

No success.
Win 8.1 Spring Update x64, FFMPEG - latest Zeranoe's builds, 32 and 64 bit.

where is it that you are not seeing thumbnails
are they not just showing up on a client?
or do they also not show in the web interface?

Thanks for help. When I change Media Receiver Type - thumbs are here.
Autodetected: Samsung Smart TV
I set: Samsung TV

Even no restart needed. If I change back - no thumbs again. LE40D550

[phibertron]

So when you use "Samsung TV" client profile the thumbs work, interesting
When you made the client profile change, did you hit the save configuration button, at the bottom of that page?
this "might" be why the change was lost on restart

[Pasha_ZZZ]

Change isnt lost on restart. But I must change manually to "Samsung TV". Profile "Samsung Smart TV" selected automatically (on 1st connect to the TS) and not showing thumbs at all.

[Pasha_ZZZ]

You was right, each restart of server Media Receiver Type changes to Samsung Smart TV. And yes, I press Save Changes each time.

[phibertron]

See if doing this helps
In the folder "C\Program Files (x86)\Twonky\TwonkyServer\resources\devicedb\Samsung"
Rename "Samsung_Smart_TV.xml" to "Samsung_Smart_TV.twonky"
In the Twonky Web Interface change the client to use "Samsung TV", click save changes
Then restart twonky server
hopefully the change stays applied

[Pasha_ZZZ]

This helps. But this is temporary workaround I think?
Quote from Samsung_TV.xml: "This is for C series of Samsung TV. Later versions have a different text here and are covered by Samsung_Smart_TV.xml".
But I have D550 TV (same as D5000, only difference is LED/LCD).

[phibertron]

Glad to hear that doing that worked
The following line in any client xml profile
is "supposed" to take care of when one manually assigns a client profile to a client
maybe this is broken in 7.3

These are the quirks from the Samsung_TV.xml

The following are not in the Samsung_Smart_TV.xml

<Quirk>RES_ADD_FLAG</Quirk>
<Quirk>POLL_RCS_PARAM</Quirk>
<Quirk>POLL_AVT_STATE</Quirk>

I think that adding the following to the Samsung_Smart_TV.xml should help
without causing any issues with clients that will use or need this client profile

<Quirk>RES_ADD_FLAG</Quirk>

See If the doing the following helps
- rename the file "Samsung_Smart_TV.twonky" back to "Samsung_Smart_TV.xml"
- add the <Quirk>RES_ADD_FLAG</Quirk> to the "Samsung_Smart_TV.xml"
- restart the server
- check to see what client profile is assigned to the problem tv
- if "Samsung Smart TV" was assigned, check to see if the additional quirk solved the thumbs issue

.

[Pasha_ZZZ]

Qiurcks change didnt change nothing. Even all the same quirks from Samsung_TV.xml.
Then I compare all XML sections and find solution. Remove this capability:

Code: Select all

<SupportedMediaProfiles>
<Profile>AASCALE#JPEG640x480</Profile>
</SupportedMediaProfiles>

under Capabilities section - and all fine, I see thumbnails.

[phibertron]

Nice!
Glad to hear that you got it working

[macnero]

I may be late on this but exactly the same problem is happening for me but on my LenovoEMX ix4-300d server. My Samsung UN55D8000 will only show thumbnails when Media Receiver Type is set to "Samsung TV" and not "Samsung Smart TV". Every time I set it, it changes back to "Samsung Smart TV".

Or should I start a new thread?

[Twonky-Rene]

If possible you should try to update to our latest Twonky 8.0.2 version of Twonky Server. We have improved the thumbnail handling and interoperability with Samsung TVs.

Furthermore, we have fixed the bug that Twonky Server did not persist the manual device selection, which you experience.
