SOLVED: Unable to transcode videos

Oof. So you are on the right kernel, definitely, but the installation of newer kernels probably removed the kernel headers and modules packages. Which are necessary for using Intel Quick Sync. I looked in Proxmox's repo and I think this is one of the packages you need.

Code:

sudo apt install proxmox-headers-6.8.4-3-pve

I'm not sure if that is all that you need to install. You can compare what other packages were install for the other kernels you have installed and just change the version to match (6.8.4-3).

Code:

sudo apt list | grep 6.8.12-1

Below are the available packages for each kernel version:

Code:

: apt list | grep 6.8.12-1

I finished installing proxmox-headers-6.8.4-3-pve.  Anything else that should be installed?

Honestly, not sure. On most systems there is also a kernel module package, which I don't see in proxmox's repos.

Reboot and try?

After installing the 6.8.4-3 headers and rebooting, transcoding no longer fails.  However, I'm noticing transcoding is taking a very long time before the video starts playing.  Previously, the videos would start playing fairly quickly.  Thoughts?

Can you share the output of "sudo dmesg | grep i915". The ffmpeg log is only showing that it is slow and not why.

Hmmmm.  The GPU initialization is fine.  HuC/GuC firmware loaded......

Do you have intel-gpu-tools installed?

Code:

sudo apt install intel-gpu-tools
sudo intel_gpu_top

While intel_gpu_top is running, initiate a transcode.  What is the core/memory frequency at?

I'm out of ideas.

@nyanmisaka - Do you have any suggestions?

[toytown]

Any chance you could upload a small snippet of the video (10secs or so) so i can test it here?
