JF ignores "default" audio and subtitle settings

[malebron]

Hi - I think this is a question many of you anime lovers must have overcome before.

I want my Miyazaki movies to play by default (=no fiddling with settings) with Japanese audio and a specific English subtitle track (of two English options available). Other users of my server may prefer the dubbed versions (subs off by default, but available).

I'm using mkv files, by the way. PGS subs are internal. I also want the Japanese audio to accompany the video with the Japanese credits.

My solution is to create two versions and use MKVToolNix to set the required options to "default" for each case. The viewer then just needs to pick the version they want and all settings are taken care of.

This works perfectly when I view the files using VLC and Kodi - the two versions play exactly as expected with the correct audio and subs for each version.

Jellyfin however seems to ignore the "default" settings (and "forced" which I also tried) - although they are labeled as such in the drop-down menus - and defaults to the first audio track (English in this case) and subtitles "Off". You can manually change them of course, but that defeats the purpose of all this work.

I know many people watch anime in Japanese with English subs, which is a similar use-case. How did you set that up?

Thanks!
