Playback issues with certain files - Schos - 2025-01-18

Hi there!
So I have been using Jellyfin for a couple of years without any major issues more with a lot of satisfaction.
Anyhow, a couple of days ago I realized, that new media was not automatically added, so I played around a lot and realized, that all of a sudden .ISO files are stopping the library scan. Which is no big deal as Jellyfin was not able to play them anyway. So right now, I am not able to play SOME media files reliable on many devices (Android TV with Jellyfin App, Mobilephone with Jellyfin App, Web Browser, Windows Client with Jellyfin Desktop App).
So I created another container with the most basic configuration (no reverse proxy, nothing), scanned the library and were not able to play some media. All my files are owned by 1000:1000, and have 664 / 775 permission.
All media is served via NFS, the container is run by root

This is my compose

Code:
services:

  jellyfin2:

    image: jellyfin/jellyfin:latest

    container_name: jellyfin2

    restart: unless-stopped

    devices:

      - /dev/dri/renderD128:/dev/dri/renderD128

      - /dev/dri/card0:/dev/dri/card0

    environment:

      - TZ=Europe/Vienna

    volumes:

      - /data/container/jellyfin2-config:/config

      - /data/container/jellyfin2-cache:/cache

      - /mnt/Media:/data/Media:ro

    ports:

      - 8097:8096

I run the container on an Intel NUC which is powerful enough for transcoding and all that.

I have a debug log as well:

Part 1: https://pastebin.com/iQ4R1TdY
Part 2: https://pastebin.com/yyQm6iGS

The log displays me starting a file and watching it for one second (search for "Mission - Impossible"). After that, I try to play two other files, but I can't find anything about that in the logs. I only see the Image of the movie with the blue loading carousel without anything happening.

My guess is some issue with remuxing / transcoding.

Please let me know what else I can supply to help you help me ;-)
Thank you!

SOLUTION:
My issue was, that the files were shared via NFSv3. Switching to NFSv4 solved everything. Be sure to check out https://jellyfin.org/docs/general/administration/storage/#nfs for more information
And for sure I misconfigured the transcoding. This post helped finding the right codecs based on my CPU: https://forum.jellyfin.org/t-playback-issues-with-certain-files?pid=49552#pid49552

RE: Playback issues with certain files - theguymadmax - 2025-01-18

Your Docker Compose file appears to be incomplete. You need to specify the user with uid:gid and include the render group for GPU access. Here's my compose file as an example. Also, debug logs generate too much noise, so we prefer to see the standard logs instead.

Code:
services:

  jellyfin:

    image: jellyfin/jellyfin:latest

    container_name: jellyfin

    user: 1000:1000  #uid:gid

    group_add:

      - "992" #render

    network_mode: 'host'  

    volumes:

      - /home/max/Dockers/Jellyfin/Config:/config

      - /home/max/Dockers/Jellyfin/Cache:/cache

      - /media/Media1:/Movies

      - /media/Media2:/Shows

    restart: 'unless-stopped'

    devices:

      - /dev/dri/renderD128:/dev/dri/renderD128

RE: Playback issues with certain files - Schos - 2025-01-19

Hi @theguymadmax

Thank you for your reply!
I am not sure about the permissions, as the container was executed by root. But I did what you asked. Added the group_add with "106" (thats my render group), added user 1000 to group 106, chown'd the jellyfin config and cache folders to 1000:1000 and added the user: 1000:1000 to the compose. With no success I am afraid.

For the sake of completness it looks like this now:

Code:
services:

  jellyfin2:

    image: jellyfin/jellyfin:latest

    container_name: jellyfin2

    restart: unless-stopped

    user: 1000:1000

    group_add:

      - 106

    devices:

      - /dev/dri/renderD128:/dev/dri/renderD128

      - /dev/dri/card0:/dev/dri/card0

    environment:

      - TZ=Europe/Vienna

    volumes:

      - /data/container/jellyfin2-config:/config

      - /data/container/jellyfin2-cache:/cache

      - /mnt/Media:/data/Media:ro

    ports:

      - 8097:8096

I also reverted the log level back to default. Please find a pastebin here: https://pastebin.com/yn65Zdrq

So, what I did was restart jellyfin (so the new logging config was loaded), played "Mission - Impossible" and stopped after a couple of seconds, and played another TV show where I know which is not working. That playback added the very last line (#63) in the log. Only one FFMpeg log file is created for the successful playback, nothing for the bad one.

Thank you for your help :-)

RE: Playback issues with certain files - TheDreadPirate - 2025-01-19

If the video is direct played, no ffmpeg log line would be created.

Just to clarify, Mission Impossible IS working now, correct?

Can you share the media info for the file that still isn't working? In the Jellyfin UI, navigate to the video in question and click on the "..." context menu and click "media info". There is a copy button at the top of the window that pops up. Click it to copy the contents of that window and share it with us.

RE: Playback issues with certain files - Schos - 2025-01-20

Hi @TheDreadPirate

Thank you for your reply!

Yes, Mission Impossible is working just fine.

Here is the information about the show in question. I replaced the title due to reasons ... and removed additional subtitles as the information was identical for all of them
Just to be clear, I already watched this episode with Jellyfin a while back before I messed up my configuration.

I tried transcoding with both VAAPI (I am very sure thats what I selected in my previous, working setup) and Intel QSV

RE: Playback issues with certain files - theguymadmax - 2025-01-20

What model of NUC do you have? Also, try playing the files that you're having issues with. If they don't play directly, the system will attempt to transcode and generate an ffmpeg log. Please share the full log.

RE: Playback issues with certain files - Schos - 2025-01-20

Not sure which exact model (I am not at home right now)
But some basic information:

Just to re-iterate: I do not think it is a hardware issue, as this file (and others) were able to play a while back.

I created a new container just to be back at default settings (as I played around with transcoding). When I play some of the not working episodes, only the last line of log from my previous post is added, nothing more. No FFmpeg logs, no transcoding popup. The blue circle spins for 30 mins now ...

What I'll try next, are older versions of Jellyfin and copying the files so I can exclude NFS.

RE: Playback issues with certain files - Schos - 2025-01-20

Guess I was too quick to answer...
I let the tab open and soon after the Episode Started: https://pastebin.com/GacBFM14
So it took about an hour for anything to happen.

There is an Ffmpg log as well but it is quite heavy. I'll be happy to share if you wish

RE: Playback issues with certain files - TheDreadPirate - 2025-01-20

Ok. It was slow to start because it was software transcoding.

Code:
-codec:v:0 libx264

It would be h264_qsv if it was using the GPU, which does have decent transcoding capability.

Can you share screenshots of how you have Dashboard > Playback > Transcoding setup?

RE: Playback issues with certain files - Schos - 2025-01-20

The settings are very default, so no hardware acceleration:
