Server System (please complete the following information):

  • OS: Raspbian (no docker)
  • Jellyfin Version: 10.8.10
  • Hardware settings & device: Raspberry PI 4 ARM64
  • Reverse proxy: Caddy
  • Other hardware notes: external HDD connected via USB3 to Raspberry

Client System (please complete the following information):

  • Device: TV PHILIPS 43PUS7906,4K, HDR, 108 cm, UHD43PUS7906
  • OS: Android TV
  • Client: Jellyfin-androidtv 0.15.11 release using integrated Exo player

The issue is that the video file will remux on official Android TV app without even showing the subtitles. I get the same result on Android phone if I disable the "Allow SSA/ASS subtitles in direct play". But on Android TV in client settings there is no option to enable "Allow SSA/ASS subtitles in direct play".

I also posted this issue in the Jellyfin TV client repository, a dev said it might add this feature someday but it's not a priority.
You can read it here: https://github.com/jellyfin/jellyfin-androidtv/issues/2875

I'm using a workaround.

From app's settings, use external player. I recommend MX Player or maybe MPV (but I haven't tried this one, I just know it's reputation on Windows because is lightweight but very powerful.).

For Android I recommend Findroid client, I believe they are also working on an Android TV version but it's not launched yet.

Thank you. Using external player can fix the case of internal subtitles, but it fails to find the external subtitles.

The underlying ExoPlayer now supports ass/ssa subtitles, and I think libVLC supports it too. I don't know why thei said that...
