Server(3.2.28.0)/CoverArt (4.0.44.0): Null reference exception when trying to use treatment override?

[Revenent 9]

Trying to use the new tag-based overrides, and I'm getting a lot of places where applying an override removes all treatment from the image.

 

Looking at the server logs, I'm seeing the following:

2017-08-22 08:25:49.852 Info HttpResultFactory: Transmit file D:\Videos\Movies\Laputa꞉ Castle in the Sky\poster.jpg2017-08-22 08:25:49.852 Info HttpServer: HTTP Response 200 to 10.1.1.1.

It doesn't matter what override I use (I've tried ca-dvd, ca-blu-ray), it just ends up with no treatment.

 

I've attached the poster image that it is using.  It was downloaded from the image service.

 

Thanks!

Hmmm.... What kind of characters are in this filename?

2017-08-22 08:25:49.852 Info HttpResultFactory: Transmit file D:\Videos\Movies\Laputa꞉ Castle in the Sky\poster.jpg

Only happening on files with such characters?

The character is Unicode character A789 "꞉"

 

No, it happens to many others:

And what if you remove the tag that you added?

For that specific one, nothing - it still doesn't have any treatment.

 

For others, the default treatment (e.g. H-264) would come back.  The "Howl's Moving Castle" one, in the second log post, reverted back to H-264 once I removed and forced-refresh the image.

Can you zip up a test image and attach it here? I just tried using ca-dvd and it seems to work fine. thanks.

Attaching.  I'm using ca-blu-ray, but I've tried ca-dvd and it doesn't work either.

Seems ok here.

 

 

Right now I am not sure what's going on so what I would suggest is waiting for the next release of Emby Server. We already have a cover art .45 update but that only applies to the beta server. Let's re-evaluate then. Thanks.

Will do.  One last thing - would enabling debug output give more information, or would it end up being the same?

[Luke 37161]

In this case no, it originally looked like a failure on the part of the image processing library to decode your image. When that happens there's usually not much we can do which is why I was surprised to see it work on my machine.

I'm still suspecting the folder names as related to the issue.  The first one has a colon in it which is obviously illegal in Windows file names.  The second one had a single quote in it.  Something in the tag processing may not be able to handle these characters properly...  but, I am guessing at this point.

The colon in the name is a "fake" colon, or specifically, it is Unicode character A789 (Modifier Letter Colon).  The normal colon, the one that Windows won't allow, is Unicode character 003A.

[Revenent 9]

Just as a follow-up...

 

I renamed all files that had the A789 colon to something in the ANSI/ASCII range and CoverArt is modifying the images properly.

 

So it does seem like either Emby or CoverArt isn't happy with special Unicode characters.

Thanks for the info.
