Nvidia Shield Transcoding while playing VOBSUB - kaliwolf - 2025-03-20
Hiya! I am new to Jellyfin and installed it on my server in a test environment different from my normal Plex installation. While testing I tried to play a movie with VOBSUB files and it was transcoding saying that "The subtitles are not compatible for Direct Play". Posted below is the results from MediaInfo on the file I was trying to play.

RE: Nvidia Shield Transcoding while playing VOBSUB - TheDreadPirate - 2025-03-20
The integrated player in Android/Android TV, exoplayer, cannot direct play VOBSUB. Since Jellyfin uses exoplayer we are limited by its capabilities. Plex uses their own playback engine.
What you could do is install the OpenSubtitles plugin, create an account on their site, and acquire SRT subtitles for your content.
RE: Nvidia Shield Transcoding while playing VOBSUB - theguymadmax - 2025-03-20
Building on what Dread mentioned, the limitation lies with the internal player, Media3 (ExoPlayer), that Jellyfin for ATV uses. However, ExoPlayer has recently added support for VobSub in their latest build. Once the ATV client updates to that version, VobSub support may be supported without the need for transcoding.
RE: Nvidia Shield Transcoding while playing VOBSUB - kaliwolf - 2025-03-20
Thanks for the help! I will go ahead and try the work around Dread mentioned while I paitently wait for Media3 1.6.0 to be released and merged into the app!
Thanks for your assistance
RE: Nvidia Shield Transcoding while playing VOBSUB - Igancio - 2025-06-21
Hello!
I had the same issue today. I have a raspberry pi 4 as server and an old Android TV with latest Jellyfin player 0.18.10. If I had the transcoding enabled the pi could not handle it. If I had it disabled, there were no subtitles. I enabled in the app to use "external player" and now I got a bad builtin TV player but at least has the subtitles.
I checked and the VOBSUB support was done in 1.6.0, and it is included in latest Android TV version for Jellyfin, so looks there might be a bug or something I am doing wrong. This is how a track looks with mkvinfo:

VobSub direct-play support is not in the 0.18.z releases of the app. It will be available in 0.19.0.
