I'm using the Android tv app of Jellyfin. I usually have to select the subtitles twice. The first time I select subtitles, it will take a long time and eventually there will be an error message and no subtitles. If I then go in and select the same subtitles again, it usually works immediately.
Is this a known problem and is there anything I can do to remedy the problem?
I guess a point to ask like the other user already mentioned is, are you using external subtitles?
Sometimes, but I haven't noticed if the failures are tied to one or the other. Thanks for the lead.
I also have regular problems with some subtitles. My solution is to enable using an external player in the jellyfin AndroidTV app (i think its under playback->advanced options) and then use VLC player which i've also installed to play the movie. That has never failed to me.
Downside is that unlike the regular exo player i don't think it supports dolby vision, so i have to change this setting back and forth occasionally. It used to be that there was an option that you could tick, so it asked you everytime which player to use before playing a movie (with the downside that it couldn't resume playing at a saved timestamp), but after a somewhat recent update this went away.
