SOLVED: Subtitles sometimes not shown

[besenwesen]

Hi!

TLDR for the solution:
you can select what subtitles jellyfin should process. In the library configuration, you can set the option "Disable different types of embedded subtitles" to "Allow All". That solved it.


I have a small problem regarding subtitles.
Some of my videos have embedded subtitles, when watching (regardless of client) the subtitle selection menu is not shown in the player. It is a consistent behavior for certain files. However, according to ffmpeg the streams and their metadata are exactly the same.

Here is the output of ffmpeg:
ffprobe file_without_selectable_subs.mp4:

Unsupported codec with id 100359 for input stream 3

I installed the subtitle extractor plugin but that does not change anything.
I run the newest stable version of jellyfin in a docker container with hardware transcoding capabilities if this is important.

Can someone point me in the right direction?
I transcoded all my media to x265 with handbrake and lately to hevc_vaapi with ffmpeg. As i am new to jellyfin and transcoding in general, i appreciate any help, even if its totally obvious.

Thanks!
(Sidequest: what does "Unsupported codec with id 100359 for input stream 3" mean? i tried filtering that stream with ffmpeg but without success.)
