Jellyfin not picking up cast of a video - happyvoid - 2024-12-06
Cast information added to mp4 file via macOS Subler editor is not picked up. What I don't understand, for another mp4 file this worked as expected.
Media Info of the file which does not show cast:
Media Info of the file which does show cast:
Ideas, as to why Jellyfin is refusing to pickup cast info from one file? This is a {Source censored - TDP} and not a movie which could be identified via one of the databases. But the same is true for the other video. Cast are added to the video file using Subler metadata-editor by added the "Cast" field and adding names in the form of "First Lastname1, First Lastname2, First Lastname3".
Custom metadata image, Genre and Description are all picked up as expected.

Are they both MP4s? Or is one of them a MKV?
RE: Jellyfin not picking up cast of a video - happyvoid - 2024-12-06
ffprobe -v error -select_streams v:0 -show_entries format=format_name -of default=noprint_wrappers=1:nokey=1 movie_file.mp4
Cast detected:
mov,mp4,m4a,3gp,3g2,mj2
Cast not detected:
mov,mp4,m4a,3gp,3g2,mj2
So that should be ok, right?

They're identical and don't provide any useful information.
I'd need the full ffprobe for each.

This is the first time I am using those commands - please bare with me 😇
no longer needed

The one that works is an M4V and the one that doesn't is an MP4. In theory the only difference between the two is that M4V supports DRM. It's Apples version of MP4 so, of course, they added DRM. MP4 should support the XML that was added and I don't see any reason in the code that would cause this. But I'm not an expert.
Submit a bug report. Provide the ffprobe output, rescan these videos, and then also include the jellyfin log.

Jellfin does not read all metadata from mp4 files.
So this is now a pending feature request. Unsure how big of a task adding support for xml metadata is. For a mediacenter software I rather surprised this is not in place yet but clearly metadata for most movies etc is picked up from online databases. Sadly that won't work for more obscure videos.
Would be really awesome to be able to manually add cast for those as well.
