KyBook 3 won't download from a Jellyfin OPDS feed #438

Open mcoms opened 2 years ago

KyBook 3 refuses to download books from Jellyfin's OPDS plugin, but will download fine from Calibre's OPDS content server.

iOS returns a MIME type error: IMG_61357689D673-1

curl reports both servers sending the correct MIME type, however Calibre sends the file as an "attachment" (with a Content-Disposition header), whereas Jellyfin streams it inline. As fas as I could see the OPDS spec doesn't have an opinion, but accepting files inline, in addition to attachments, may prove compatible with more servers.
