Hello everyone,
I have a Qnap server, but I get the same error message when transcoding. (at least at 20Mbit)
With the jellyfish video I could not repoduce it but with the movie Ready Player One in 4K HVEC 74k Bitrate I could.
I don’t know if it helps or if a thread should be created for this, but I’ll post my logs.
Version 1.40.3.8555
Qnap QTS 5.1.7.2770
T600 GPU
Windows version 1.96.0.177-dc5df788

I moved you here because QTS and TrueNAS operate very differently.
The QNAP is running the native application where TrueNAS is using Docker.
Would you please turn VERBOSE logging OFF ? It only serves to complicate debuffing because it’s reporting every packet received or sent…
After changing the logging level, please restart PMS.
I did find this where the block of data was transcoded.
Could this be a player problem?

I activated the debug logging again and restarted the server.
I was able to reproduce the error with the Windows app, iOS app as well as Android (cell phone) and Android (TV) were able to play the transcoding in various stages without errors.
I am not at all experienced in being able to read an error in the code now. Loopback shouldn’t occur though I guess.
Here are the new logs again. If I can help with more info/logs, please let me know

Would you please recreate the error with Plex/web and attach that logs ZIP please ?
Unfortunately I can’t get it to work, in Plex Web I can only select 720P / 2 Mbit as quality…
Plex/web has a quality setting just as all the other players. It’s a little obscure to find it (mid-upper left in browser). Was it set for more than 720p/2Mbps? — which is the default for an indirect/plex-relay connection.
After restarting PMS, more quality levels were available at once.
I have now played the same movie in Plex Web, at 20 and 12Mbit nothing loaded (black screen) but no error was displayed.
10 and 8Mbit could be transcoded and played.

Both of the QNAP-provided Nvidia packages (kernel and runtime) are installed and QTS restarted ?
PMS looks for a card at PMS start.
The card must be in “QTS mode” (Control Panel - Hardware)
(PMS can only use
Thanks for the feedback but I think I need to elaborate a bit more on my server.
My server has been running for 4 years without any problems, the whole setup is not new. But since I have been away for the last 4 weeks, I had to transcode series or movies more often.
In rare cases, this error code has been displayed.
The Nvidia graphics card is of course running in QTS mode and all the necessary drivers are installed and up to date.
Because of the other thread with the same error message (TrueNAS), I got in touch and wanted to contribute logs to localize the error.
I will try other movies than Ready Payer One or series this weekend. I get no error message via Plex Web, just a black screen. This could also be due to the TrueHD / DTS-HD audio transcoding.
Please look carefully at the nvidia-smi output.

oh, okay! I hadn’t noticed that
But I only used the nvidia-smi command for the first time recently…
I uninstalled the Nvidia GPU driver, restarted the server and reinstalled the driver. But I can’t delete or stop the NVKernel driver.
The Cuda driver is still not available in nvidia-smi.
Can I install it manually?
I forget how that works.
You need to ask QNAP.
From what I remember, you can go into the shell and manually uninstall them
(there’s a uninstall.sh file somewhere
I was able to remove the kernel driver using the uninstall command.
I had to reinstall the GPU driver several times until the driver worked.
The CUDA driver is still not available
I’m at a bit of a loss now, I can’t do more than uninstall and reinstall
Can you confirm, in Control Panel - Hardware, the GPU is in “QTS Mode” ?
I wonder if you got an update to the drivers?
(Your card is not listed)
https://www.qnap.com/en-us/compatibility/device_category=gpgpu&brand=nvidia
Here’s where you can get older versions.
https://www.qnap.com/en/download
The fact that the card is not listed should not really matter with the same chip (TU117). Otherwise it would not be recognized
I have contacted Qnap to officially support and list the GPU T400 and T600.
The hardware transcoding works anyway, without Cuda.
