Yet another Decoding issues with Nvidia - FFmpeg 218 - ehellas - 2025-08-31
I am facing some issue with decoding issue with Hardware acceleration activated. I've read multiple guides but I can't really find what I have to disable at this point.

I am using Jellyfin 10.10.7 in a container.
I am using a GTX 660 with Driver 470 (last supported for that gpu)
I've already checked and nvidia-smi works as intended inside of the container.
I have only H264, MPEG-2 and VC1 checked in transcoding, since those are the only available according to the GPU transcoding support matrix (https://en.wikipedia.org/wiki/NVDEC).

What does the ffmpeg log say?
RE: Yet another Decoding issues with Nvidia - FFmpeg 218 - ehellas - 2025-09-02
Sorry, took didn't receive an e-mail with a comment. And took a while to find the ffmpeg log but I did, and that pretty much answers my question. I think I have to find an ffmpeg that accepts nvenc 11.1 maybe?

Sounds like drivers are out of date. Are there newer drivers supported by your card?
Code:

Due to beeing an older card, it can't go above Nvidia 470.xx
I might need to compile a special container for my use case.
RE: Yet another Decoding issues with Nvidia - FFmpeg 218 - ehellas - 2025-09-03
Well, just did an OS upgrade from Ubuntu 22.04 to 24.04 and it works flawlessly now, even with hardware encoding.
Didn't touch anything regarding the containers, it just worked TM.
Weird. Well, can't complain though.
