Hardware Transcoding Issue Arc A310

[myradishes]

I'm having trouble playing a certain file on a roku device which I believe is running into a failure due to a transcoding problem. I believe I have transcoding setup correctly for my Arc A310 passed through to an lxc container in proxmox.

renderD128 has been configured to point at renderD129 in case it defaults to trying to use 128. Specifying 128 in the previous ffpmeg command yields the same output noting the A310 card.

I've tried using QSV and VAAPI(tested while specifying 129 then 128 after that failed).

What kernel is the host running?

Code:

uname -a

Also, you should only be passing in ONE of the renderD devices. Probably card1 and renderD129. I'm assuming you have an AMD APU/7000 CPU or Intel CPU with an iGPU

And you should setup and enable low power encoding since it is required for Intel Arc. But we can get to that after you answer the question about which kernel your system is running.

[myradishes]

Yes, this is on a system with an Intel iGPU. Deleted entries in /dev/dri so only renderD129 is left, was expecting one of the cardNs to survive that haha. Transcoding options selected, decoding QSV h264 hevc mpeg2 vp9 av1 hevc-10b vp9-10b prefer os native, enable hardware decoding lowpowerh264 lowpowerhevc, allow encoding hevc allow av1, enable vpp tone mapping, enable tone mapping.

No apparent change enabling the low power options.

Realized what I did wrong here, the guide I followed was for an unprivileged container but mine is privileged so I had the wrong uid/gid set. It's playing now and I see the A310 being used on the host node's intel_gpu_top. For the low power option you mentioned how can I verify that is being used properly after enabling low power h264/hevc hardware encoder?

Also, it appears despite the tv/roku being turned off jellyfin is still transcoding the movie for some odd reason? Looks like it eventually killed the transcode at some point, it was going for maybe 5-10 minutes haha.
