Troubleshooting Intel B580 GPU for encoding - chanthemad - 2025-09-25
So I bought an Intel Arc B580 (Battlemage) GPU in order to do some encoding for Jellyfin. I'm running Ubuntu 24.04 LTS 6.14 HWE Kernel.
However, I can't get it to work. I followed https://jellyfin.org/docs/general/post-install/transcoding/hardware-acceleration/intel#linux-setups
I did check version of the intel-opencl-icd. It is up to date.
Then I checked the supported QSV/VA-API codecs. How it supposed to look like is this:
sudo /usr/lib/jellyfin-ffmpeg/vainfo --display drm --device /dev/dri/renderD128
libva info: VA-API version 1.17.0
libva info: Trying to open /usr/lib/jellyfin-ffmpeg/lib/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_17
libva info: va_openDriver() returns 0
Trying display: drm
vainfo: VA-API version: 1.17 (libva 2.17.0)
vainfo: Driver version: Intel iHD driver for Intel® Gen Graphics - 23.1.2 (xxxxxxx)
vainfo: Supported profile and entrypoints
Mines looks like this:
sudo /usr/lib/jellyfin-ffmpeg/vainfo --display drm --device /dev/dri/renderD128
Trying display: drm
libva info: VA-API version 1.22.0
libva info: Trying to open /usr/lib/jellyfin-ffmpeg/lib/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_22
Bus error
How would I fix this bus error?
Also I checked the Open CL runtime status. Supposed to look like this...
sudo /usr/lib/jellyfin-ffmpeg/ffmpeg -v verbose -init_hw_device vaapi=va
dev/dri/renderD128 -init_hw_device opencl@va[AVHWDeviceContext @ 0x55cc8ac21a80] 0.0: Intel® OpenCL HD Graphics / Intel® Iris® Xe Graphics [0x9a49]
[AVHWDeviceContext @ 0x55cc8ac21a80] Intel QSV to OpenCL mapping function found (clCreateFromVA_APIMediaSurfaceINTEL).
[AVHWDeviceContext @ 0x55cc8ac21a80] Intel QSV in OpenCL acquire function found (clEnqueueAcquireVA_APIMediaSurfacesINTEL).
[AVHWDeviceContext @ 0x55cc8ac21a80] Intel QSV in OpenCL release function found (clEnqueueReleaseVA_APIMediaSurfacesINTEL).
...
Mines looks like this:
sudo /usr/lib/jellyfin-ffmpeg/ffmpeg -v verbose -init_hw_device vaapi=va
dev/dri/renderD128 -init_hw_device opencl@va -init_hw_device opencl@va

Bus error
Another bus error. So my question is, how do we fix this problem?
When I try to detect the GPU with lspci -nn | grep -Ei "3d|display|vga"
11:00.0 VGA compatible controller [0300]: Intel Corporation Device.. [8086:e20b]
It is getting picked up.
Also on the encoding dashboard, which codecs should I check?
Thanks in advance.
RE: Troubleshooting Intel B580 GPU for encoding - chanthemad - 2025-09-25
Well I fixed it, I just checked to enable Re-sizable BAR or ReBAR in the BIOS.
I posted this on this forum because I thought I had enabled it in the BIOS, but upon further review, it wasn't enabled.
Credit this post for pointing me in the right direction. https://github.com/jellyfin/jellyfin/issues/13944
Curious, what encoding settings should I use now?
