Can't seek when playing a particular file

[altair21]

hey folks,

I have this weird issue where the file itself plays fine but I just can't seek in it, whenever I do forward, it skips back to its original position, and if I play the file in its entirety, it'll play fine, I have rehashed the file multiple times, grabbed it from different sources, but the issue persists, its a season pack and all files in that season pack show the same issue.

Here's the mediainfo for it: https://pastebin.com/p2taSH1Y

would really appreciate any help for this, my tv direct plays this file so there's no log for it in jellyfin, and I dont know how else to debug this. This is specifically an issue with Jellyfin on WebOS on my LG G4, when I try to seek in my web browser, it seeks fine but in that case, it triggers a transcode which I am assuming fixes whatever was wrong.

I'm on Jellyfin Server 10.10.1 and latest updated version on webos

just an update: as soon as i disable TrueHD under playback, seeking works but audio doesn't play as expected

Can you update to 10.10.5? Just to ensure that the issue you are referencing has been fixed already.

Make a backup before upgrading, as always.

Hey missed this, but I just upgraded to 10.10.5 and still the issue persists, not sure how to debug it

Can you share your full Jellyfin log via privatebin.net? And if there are ffmpeg logs, share those too.

Hey, No ffmpeg logs since its direct play, though if I turn off DTS, it does play perfectly except for the audio, I have attached the latest log here https://privatebin.net/?1bec7d8a4bec90ab...k7BZTXDoc5 


thanks!

P.S. Please search for "Suits" in the log to find the file, specifically it'll be S03E01 of Suits

Can you try remuxing the file? This problem can be caused by a poorly encoded/muxed file. We can copy the video/audio/subtitles to a new file that is properly structured.

Open a command prompt.

Code:

cd C:\Program Files\Jellyfin
ffmpeg.exe -fflags +genpts+igndts -i "E:\path\to\problem\video.mkv" -map 0 -codec copy -max_muxing_queue_size 2048 -max_interleave_delta 0 -avoid_negative_ts disabled E:\newFile.mkv

Had this issue with another file I played, here's the media info for audio

Code:

Audio
Title: English - TRUEHD - 5.1 - Default
Language: eng
Codec: TRUEHD
AVC: No
Layout: 5.1
Channels: 6 ch
Bitrate: 3358 kbps
Sample rate: 48000 Hz
Bit depth: 24 bit
Default: Yes
Forced: No
External: No

G4 doesnt support TRUEHD codec afaik, so I had to disable both DTS playback (not sure why I have to disable this) and TrueHD playback and enable transcoding of video files which need audio encoding, before the file played, but again seeking didnt work for me.

I'll try hunting up the original Suits file too and try remuxing it


P.S. Can someone explain why TrueHD is not working with G4? I havent found any thread which says TrueHD support is not there, and also if I dont disable both DTS and TrueHD playback, the above file wont work at all
