double subtitles

[RichardLuo0]

Hi, this is my first time using Jellyfin, so I am not sure if I set everything right. But here is the issue: there will be double subtitles (english and chinese) if I have Chinese subtitle turned on.
I already tried the subtitle mode option in settings and it doesn't affect anything.

[RichardLuo0]

Btw, the issue doesn't appear on the web version

[RichardLuo0]

The Android version doesn't have the issue too
And I find it strange that even if I turn off subtitles completely, the English subtitle still appears

[dmitrylyzo]

My guess is that there's something wrong with the indices.

What TV model?
What Jellyfin version?
What container of the media you are trying?
What format of subtitles? Embedded or external?
Or maybe just post Media Info (3dot button on the item).
What play method (you can see it in Player Setings -> Playback Info)?

I forget the TV model, its a very old one. web os 4.06.25
Jellyfin 1.2.2

web os 4.06.25

This is the firmware version, not the webOS version.
If it is around 2015, it is webOS 1 or 2.

Jellyfin 1.2.2

This is the app version. What version of Jellyfin server?

We have reports of playback not working when there are too many subtitles.

Could you try lowering the maximum audio channels (in User Settings (avatar) -> Playback -> Maximum audio channels, select Stereo and Save)? This should transcode the audio but not the video (Direct streaming) and, in theory, show only selected subtitles.

[RichardLuo0]

This is the app version. What version of Jellyfin server?

Jellyfin.Server 10.9.2.0

We have reports of playback not working when there are too many subtitles.

I did not encounter any playback issues though.

Its too late and I am going to sleep now, I will reply to you tomorrow.

[RichardLuo0]

If it is around 2015, it is webOS 1 or 2.

Web OS 2.2.3-2155

changing audio channels does not work

[dmitrylyzo]

changing audio channels does not work

It doesn't switch to direct streaming or what?
Check it in Player Settings -> Playback Info (Play method).

The idea is to try forcing it to change the play method to HLS so there are no subtitle tracks left.

[RichardLuo0]

[dmitrylyzo]

OK, another plan.

1. On PC, go to Dashboard -> Users -> user you are using on TV -> disable Allow audio playback that requires transcoding and Allow video playback that requires transcoding -> save.
   Allow video playback that requires conversion without re-encoding should be enabled.
2. On TV, after playback starts, Player Settings -> Quality - > lowest value.

This should force it to remuxing (also HLS).

[RichardLuo0]

This works

[RichardLuo0]

Does remuxing cause any performance issues? Can I use it all the time?
And will you make a permanent fix soon?

[dmitrylyzo]

Does remuxing cause any performance issues?

Not so much compared to video transcoding - it simply copies streams to a different container. So, imo, the main problem is that it requires extra space (~size of the original file - depends on the number of tracks) in the transcoding folder.

Can I use it all the time?

It should be enabled anyway if you want to play MKV in browsers.

And will you make a permanent fix soon?

I don't know what the cause of the problem is yet.

[dmitrylyzo]

How many subtitle tracks are in the file?
I tried video+audio+50subs in the webOS 1.2 emulator - works fine.
video+audio+100subs also works.
488subs (all possible languages) doesn't start playback.
