What's the version of your Jellyfin server?

[CommanderRedYT]

Version 10.8.5 running on ODROID HC4 (arm64)

[msycn]

I think same issue only appears in episodes, because the app times out after all videos have been requested https://github.com/jarnedemeulemeester/findroid/issues/187

If you play the last episode of Season will faster than from the first episode

[CommanderRedYT]

What I don't get is why the error only appears with about 4 seasons of a show, but all other 8 shows or i dont know how many movies work just fine.

I've looked at the metadata of the mp4 files and they do not have something that could have something to do with it.

some issues

[AnonymousWebHacker]

The problem is with the server how to deliver the data to android clients, or problem of android clients,[ findroid or jellyfin client.] This happens when, for example, you have an mp4 video with a dual subtitle or a forced subtitle with ffmpeg without metadata.

Temporary solution, is to put the video in an mkv container (no need to transcode)

This error occurs in both findroid and jellyfin client for android, however it does not occur in desktop versions. I really think the problem is from android clients with mp4 videos and embedded subtitles

[jarnedemeulemeester]

This has been fixed for quite some time now. The deserialization error originated from the jellyfin kotlin sdk.
