fix: add image/jpg to MIME type extension lookup

2026-04-18T13:38:17Z

Although image/jpg is not a registered MIME type (RFC 2046 specifies image/jpeg), several external providers return image/jpg as the Content-Type for JPEG images: - TMDb API (thumbnail/episode images) - Schedules Direct EPG - Various other metadata providers Without this mapping, Jellyfin throws ArgumentException: 'Unable to determine image file extension from mime type image/jpg' This causes library scans to fail when saving episode thumbnails and other images from these providers, leading to repeated scan failures and cancelled library scans. PR #7052 previously added this but it was lost during the migration to FrozenDictionary. Issue #13568 reports the same bug in 10.10+.

Add missing MIME types for comicbook formats (#11010)

2024-02-15T22:15:14Z

* Correct MIME types for comicbook file extensions cb7, cba, cbr, cbt and cbz all refer to different types of digital comicbooks. The last letter of the extension indicates the compression algorithm that was used: 7zip, arc, rar, tar or zip. All these filetypes used to have the `application/x-cbr` MIME type assigned to them. However, that has since been deprecated and was replaced with - `application/vnd.comicbook-rar` for rar compressed files and - `application/vnd.comicbook+zip` for rar compressed files. Only these two are officially listed by IANA https://www.iana.org/assignments/media-types/application/vnd.comicbook+zip . cbr and cbz are by far the most common file extensions for comicbooks. There's no official MIME type for cb7, cba or cbt files. However, with rar being a proprietary compression algorithm, FOSS applications will often refuse to handle files that identify themselves as `application/x-cbr`, so I decided to assign extension specific MIME types to them. I've seen these being used by other applications, specifically comic book readers. I've read through the docs on iana.org, but haven't figured out why they chose `-rar`, but `+zip`. * Add conversions from MIME type to file extensions for comicbook formats cb7, cba, cbr, cbt and cbz all refer to different types of digital comicbooks.
