Thumbnails mostly black

I have recently upgraded Serviio.
I run it on my NAS, so manually upgraded serviio to 1.9, Java to 1.8.0_151 and ffmpeg to 3.2.7.

After the upgrade I did a complete reload of my file library and since then most of my thumbnails have turned black. I mean less than 1% of the thumbnails have a picture, so it is not completely broken, which just makes it even more confusing.
I tried to turn on debugging and all seems fine according to the log. Here is a part. I edited it to remove the stuff that does not seem relevant.

  Code:

Re: Thumbnails mostly black

don't you have some (potentially hidden) images in the folders where your files are? like folder.jpg, etc. They would be used with preference.

In the log it says:
2017-12-10 20:30:12,327 DEBUG [CoverImageInFolderExtractor] Found cover image Bicycle Thieves-poster.jpg
That file looks fine.

I can also see a hidden folder called ".thumbs". Is that one serviio makes?
In there I have 3 files: "Bicycle Thieves.mkv.jpg", "Bicycle Thieves-fanart.jpg.jpg" and "Bicycle Thieves-poster.jpg.jpg". They all look fine.

Re: Thumbnails mostly black

no, Serviio doesn't make it. It's probably Windows.

Its probably the program I use to make the .nfo files then.

No idea what can cause the black thumbnails?

Edit: Solved the .thumb folder mystery. Its apparantly a feature of myZYXELcloud. Turned it off.

Re: Thumbnails mostly black

To get the ball rolling on this on, is there anyway to debug a little further?
Is there a command I can execute to see if it's some external program that's the problem?
Someway I can check the images in the database maybe?
Anything? :D

Re: Thumbnails mostly black

This is a bit weird in the log

  Code:

2017-12-10 20:30:20,598 DEBUG [CoverImageService] Image successfully resized


The HD thumbnail is resized to 15kb, the standard 160x160 is then further resized but end up 907b, which seems very small.

Resizing is done by Java, so not sure. You could update your profile to use HD thumbnails (see the XboxOne profile for example).

Didn't work unfortunately.

I should think they are proper binary files. Were examples with the same error, from reading files from www.thetvdb.com as well.

I run "Java 1.8.0_151-Oracle Corporation arm".

Re: Thumbnails mostly black

Are you on Synology NAS? I think I've seen this before and it was related to the Java distribution on the NAS.

Zyxel NAS. Fetched the Java dist from the official site.
Will try and upgrade Java this weekend and see if that changes anything.

Re: Thumbnails mostly black

maybe there is OpenJDK Java, rather than the Oracle one?
