[Issue]: Thousands of "Error reading image tag"

[jgoerzen]

Please describe your bug

While scanning my photos library, I get thousands of errors like this one:

[2022-12-07 18:20:34.978 +00:00] [ERR] [39] Emby.Photos.PhotoProvider: Image Provider - Error reading image tag for "/Pictures/2010s/2011/09/water-splashing/IMG_1592.JPG"
System.IndexOutOfRangeException: Index was outside the bounds of the array.
   at System.Collections.Generic.Dictionary`2.TryInsert(TKey key, TValue value, InsertionBehavior behavior)
   at TagLib.IFD.IFDReader.StartIFDLoopDetect()
   at TagLib.IFD.IFDReader.Read(Int32 count)
   at TagLib.Jpeg.File.ReadAPP1Segment(UInt16 length)
   at TagLib.Jpeg.File.ReadMetadata()
   at TagLib.Jpeg.File.Read(ReadStyle propertiesStyle)   at TagLib.File.Create(IFileAbstraction abstraction, String mimetype, ReadStyle propertiesStyle)
   at Emby.Photos.PhotoProvider.FetchAsync(Photo item, MetadataRefreshOptions options, CancellationToken cancellationToken)

What's more, it appears that these items are never actually indexed, as it does this lengthy scan again and again (taking hours each time).

I would be happy to send a sample image to someone privately.

The image tags, if they exist, would have been written by digikam.

This is Jellyfin 10.8.8

See above.  That message is repeated thousands of times due to the number of photos in my library.

this issue is affecting me with version 10.8.13 running on windows 11 pro

slightly different error though:

I also have this problem. I get the same error as original poster.

I am also having this issue with supposed JPEG files (at least they do work as JPEG files on my system).

It seems, that Jellyfin uses the most recent version TagLibSharp (v2.3.0). It in turn uses ImageSharp v1.0.4 (see https://github.com/mono/taglib-sharp/blob/main/src/TaglibSharp.Tests/TaglibSharp.Tests.csproj). Now while I am not sure if it's e.g. a WebP file, before I got here, I found https://stackoverflow.com/questions/70792715/getting-missing-soi-marker-from-jpegdecoderr and SixLabors/ImageSharp#121, which contain some info about missing SOI markers.

I also found, that ImageSharp's newest version is v3.1.4 (not v1.0.4), meaning, that TagLibSharp is old.

Therefore they should introduce a fix if possible, though seeing as major versions have changed, I'd expect breaking changes. Perhaps someone can make a PR over there and then perhaps over here, but sadly I don't have the time necessary to do this properly.
