Trouble playing some media files - gariak - 2024-06-27

I'm having trouble playing certain media files that I created myself years back using Handbrake.  These same files used to play without issue since I first installed Jellyfin a month or two ago, but it's not clear to me what changed or was upgraded since the last time it worked, which was fairly recently.  These same files also currently play well in VLC.  I'm currently running Jellyfin 10.9.7 as an essentially dedicated server on lubuntu via the Debian repo with no containerization and primarily serving over my local network.  The error I get is immediate and unhelpful: "Playback failed due to a fatal player error."  I've gone through the docs to make sure I hit all the important points of the installation.  I've tried searching various aspects of this issue, but most of what I find seems to relate to transcoding or Docker containers and I don't understand the logs well enough to grasp what's going wrong.

Unless I'm mistaken, this shouldn't be a transcoding problem, as I'm not seeing ffmpeg logs showing up at all and I should be able to play the straight files without issue.  Unless being unable to trigger a transcode IS the problem and the lack of ffmpeg logs is the diagnostic clue.  I'm fairly technically minded and happy to try whatever is suggested.

Other things I have tried since noticing the problem that have led to no improvement:
Reinstalling jellyfin-ffmpeg6
Ensuring I have a renderer and that jellyfin has been added to the proper group
Updating Jellyfin via apt
Updating everything else via apt
Rebooting
Changing my transcoding hardware acceleration settings to VAAPI and back to None
Playing via Roku Jellyfin app and on my phone

Relevant bit of my Jellyfin logs:

RE: Trouble playing some media files - TheDreadPirate - 2024-06-27

It looks like it is failing to extract the attachment. Possibly a font for ASS subtitles?

If you're playing the video with subtitles, what happens when you don't select any subtitles?

Does it only happen with a particular video or set of videos?

RE: Trouble playing some media files - jellybro - 2024-07-26

I am having the same issue. There is no transcode is triggered. The video does play when the subtitles are off. Any form of subtitles turned on crashes the stream.

It seems to be happening to a number of South Park episodes.

RE: Trouble playing some media files - TheDreadPirate - 2024-07-26

Can you post your full jellyfin logs to pastebin and link back here?

RE: Trouble playing some media files - jellybro - 2024-07-29

https://pastebin.com/U0JgkFcp

I turned on debug mode. Tried to clip a helpful segment.

Thanks!

RE: Trouble playing some media files - TheDreadPirate - 2024-07-29

Do you have transcoding disabled? It wants to transcode and burn-in the subs because the client doesn't support the subtitle type.

RE: Trouble playing some media files - jellybro - 2024-07-29

Here is a transcode log from another media file.

https://pastebin.com/mvb5vask

RE: Trouble playing some media files - TheDreadPirate - 2024-07-29

Upon further inspection, it looks like it was attempting to extract the subtitles to send to the client separately but failed.

Code:
System.NullReferenceException: Object reference not set to an instance of an object.
   at MediaBrowser.MediaEncoding.Attachments.AttachmentExtractor.<>c.<ExtractAllAttachments>b__8_0(MediaAttachment a)

I'm wondering if the subs are corrupt or something.

What happens when you try to manually remux one of the south park files?

Code:
/usr/lib/jellyfin-ffmpeg/ffmpeg -fflags +genpts -i "/path/to/library/South Park - S20E02 - Skank Hunt.mp4" -map 0 -codec copy newFile.mkv


RE: Trouble playing some media files - jellybro - 2024-07-29

The stream with subtitles work with the remux as you specified.

I should mention that the original files work with subtitles on VLC.

RE: Trouble playing some media files - TheDreadPirate - 2024-07-29

VLC isn't a good measure for whether a file is good or not. VLC will power through corrupt/malformed files.

Jellyfin does not have its own playback engine. We use open source players like MPV in Jellyfin Media Player. But all/most of our other clients we are reliant on how tolerant the device's embedded player is to malformed/corrupt files. Most tend to skew towards requiring files be formatted properly and standards compliant while having a low tolerance for corruption.
