Transcoding with Intel Arc A750 Not Working

[jos64]

Hello all,

I am currently in the process of re-building my Jellyfin server.

Originally I was running a Debian 12 virtual machine with Jellyfin installed, passing through an Intel Arc A750 via a VMware host. Transcoding with this setup worked flawlessly.

Now, I am re-building Jellyfin using a Jellyfin portable setup along with jellyfin-ffmpeg on a Fedora 42 Server Edition virtual machine (Jellyfin version 10.10.7) on a Fedora 42 KVM/QEMU host, also passing through the same Intel Arc A750.

I've installed what I believe is required for this to work, but I just can't get it to. I've been at this for 1 week. I've even rebuilt the server to see if that would solve my issues, but it didn't.

I've installed the following packages on the system:
- intel-opencl
- libva
- libva-utils
- libva-intel-media-driver
- intel-gpu-tools
- intel-mediasdk
- intel-vpl-gpu-rt
- intel-compute-runtime

My Transcoding settings are as follows:
- Hardware acceleration: Intel QuickSync (QSV)
- QSV Device: /dev/dri/renderD129
- Enable hardware decoding for: H264, HEVC, MPEG2, VP9, AV1, HEVC 10bit, V9 10bit
- Prefer OS native DXVA or VA-API hardware decoders [ON]
- Enable hardware encoding [ON]
- Enable Intel Low-Power H.264 hardware encoder [ON]
- Enable Intel Low-Power HEVC hardware encoder [ON]

I hope someone can point me in the right direction.  Below are a couple of log entries that stand out to me.  Thank you for your time.

Below is the log entry for an attempt at playing a movie file (2160p DV/HDR H265), which shows that ffmpeg gets stuck:

If I try running that same ffmpeg command, it also gets stuck at
