Sudden transcoding issue with Radeon 680M - will.rkr - 2025-05-09
I installed Jellyfin in a privileged LXC container on proxmox. I passed through /dev/dri/card1 and /dev/dri/renderD128 and everything worked smoothly yesterday. I confirmed that HW transcoding (AMD AMF) was enabled and played a couple of 4K movies without issues.
This morning I noticed the container had halted. Oddly, even without rebooting the PC, /dev/dri/card1 was now card0. I updated the passthrough, powered it off and on. But now I can no longer play any videos with HW transcoding. Turning off HW transcoding enables me to play 480P movies but not 4K.
I also tried VAAPI but the same error. When I ran this command, it generated errors below.
/usr/lib/jellyfin-ffmpeg/ffmpeg -v verbose -init_hw_device vaapi=va
dev/dri/renderD128 -init_hw_device opencl@va----
No matching devices found.
Device creation failed: -19.
Failed to set value 'opencl@va' for option 'init_hw_device': No such device
Error parsing global options: No such device
I installed the latest AMD GPU drivers and followed this guide.

Happy to upload logs if those are useful. Here's a snippet from my one of my streams which seemed relevant.
Stream mapping:
Stream #0:0 (mpeg2video) -> setparams:default
Stream #0:5 (dvdsub) -> scale:default
overlay:default -> Stream #0:0 (av1_amf)
Stream #0:1 -> #0:1 (ac3 (native) -> aac (libfdk_aac))
