Playing next episode is breaking the subtitles

[kerkmann]

Describe the bug

Description of the bug

Watching an Anime in Jellyfin is working without any problems. but when I am watching with a subtitle (for example German) it's working without any problems. Until I've watched the entire episode and click "next episode". When the next episode is starting, the same subtitle is automatically selected. But there is no subtitle in the playback of the video. If I disable the subtitle on enable it again, it's working in the playback.

Kind strange, the subtitle and movie is working without any problems, but I need to disable and enable it after each episode. The Anime doesn't matter, I have that problem with around 50~ Anime. ^^"

Steps to reproduce

1. Start an Anime
2. Enable a subtitle
3. Watch the entire episode without any problems
4. Play next episode
5. Broken state: Subtitle is enabled but the playback is not playing the subtitle, audio and video is working.

Seeing the same thing on Tizen/Samsung. Video files are mkv with EAC3 audio, subtitles are English Forced PGSSUB.

My preference is set to English. The first episode in a watch session will play everything perfect, then the next episode will autoplay, still set to English, but will display French subs until I set it to something else then back to English.

More than happy to submit a report elsewhere.

I can confirm this issue as well with Android Version 2.6?0 and Server 10.8.13

I'm using the web player.

Skipping manually between episodes is also causing this behavior.

I think the problem is not only the android app. I've seen some anime which had the same problem in browser. :(

[kagurazakahope]

Same issue on Windows server and Windows Firefox. Subtitle not shown when switched to next episode either automatically or manually. Going back and play again would work it around.

Same issue on my truenas scale server

Seems to primarily be a web issue, so unfortunately out of scope for the app to fix.

For the integrated player, this might also happen (with subtitles explicitly getting disabled), which is a separate issue and should be fixable.
