jf 10.10.7 Ugreen 4800 plus - Playback failed due to a fatal player error

[fisao]

Hello everyone, 

I have not found a solution to my exact problem in the search functon of this forum and am therefore starting this new thread

I have the following error: 
"Playback Error Playback failed due to a fatal player error."

on the following setup: 
jellyfin 10.10.7 on Ugreen DXP4800plus (32GB RAM)
running the stock OS (UGOS I believe) in version 1.5.0.2628
installed via Docker image 

my file setup is: 
Cache

/config/cache

Logs

/config/log

Metadata

/config/data/metadata

Transcodes

/config/cache/transcodes

Web
/usr/share/jellyfin/web

and I have attached the latest log output for the last three attempts.

- the playback error seems to only occur on x265 HEVC 10bit files 
- when hardware encoding is enabled, for all file formats -> always immediate fail 
- when hardware encoding is disabled -> transcode starts, but is understandably very laggy, so not a solution unfortunately

the cpu on the machine is (I believe):
- Intel Pentium Gold 8505 4400 5 Cores 6 threads with 32 GB of RAM (because I had it available, it is of course overkill)

I see that ffmpeg is exiting with an 187, but I am not knowlegeable enough to understand why in this case

I would be immensely grateful if anybody could give me some pointers as to what could be done to remedy the situation

Please let me know if any additional information that I could provide could help, thank you very much if you can

Hey fisao,
I have literally the same hardware and also using the pre-installed UGOS. I can make the Jellyfin app to start in a docker container, make it find the media folder (it finds all the files and lists them in the library), but I could never figure out how to troubleshoot the "Playback failed due to a fatal player error". Docker logs do not show errors, webbrowser dev-tools do not show the error message. For any settings, be that with hardware acceleration or not, with admin docker permission or not, I can't make it work with any file.

Now is the tricky part. By authenticating into the docker container using ssh, I could check if the ffmpeg is showing any errors with the following command:


root@xxxxxxxxxxxx# /usr/lib/jellyfin-ffmpeg/ffmpeg -i "/data/Music.mp3" -acodec aac -v "debug" -f mp4 /cache/test.mp4


And the output on interruption was this:


[in#0/mp3 @ 0x558811278100] Input file #0 (/data/Music.mp3):
[in#0/mp3 @ 0x558811278100] Input stream #0:0 (audio): 22668 packets read (16726656 bytes); 22667 frames decoded; 0 decode errors (26112384 samples);
[in#0/mp3 @ 0x558811278100] Total: 22668 packets (16726656 bytes) demuxed
[AVIOContext @ 0x558811281080] Statistics: 16744448 bytes read, 0 seeks
Exiting normally, received signal 2.


so I just assume that ffmpeg _can_ read the file and the problem is in permissions.

How did you test the transcoding? I seriously wonder why you have no issues with some file formats and with the same software+hardware I get errors.

The main issue I think is that it can't access an iGPU/ GPU.

Did you guys passthrough your iGPU to the docker container?
Is it running as privileged?

Can you share docker compose file?
