transcoding settings

[chenks]

i've set up jellyin as an LXC in proxmox (ubuntu OS)
it's running fine but just want to check i have transcoding options set correctly.

the host CPU is 12th Gen Intel® Core™ i3-12100 (8 cores)
the iGPU has passthru enabled correctly in proxmox (i believe)

Code:

root@proxmox:~# lspci -nn | grep -Ei "3d|display|vga"
00:02.0 VGA compatible controller [0300]: Intel Corporation Alder Lake-S GT1 [UHD Graphics 730] [8086:4692] (rev 0c)

using this guide i can see that my alder lake CPU supports most options
https://en.wikipedia.org/wiki/Intel_Quic...d_encoding

i've set hardware decoding to Intel Quicksync (QSV)
i've enabled the following

and left all the other options as default

for trickplay i've enabled "hardware decoding" and "Enable hardware accelerated MJPEG encoding" and left all other settings blank.

does this look all ok or should i be doing anything else?
should i also enable "enable tone mapping"?

You can also check both of the HEVC RExt boxes. And, if you haven't already, you can check "Allow encoding in HEVC format".

https://github.com/intel/media-driver?ta...g-features

You can check both tone mapping boxes. Just make sure you installed the intel-opencl-icd package.

You can check both low power boxes as long as you've setup the GuC and HuC firmware. I THINK this needs to be done in Proxmox and not the LXC.

You can check both tone mapping boxes.  Just make sure you installed the intel-opencl-icd package.

ah ok, so "enable tone mapping" and "enable VPP tone mapping"?
i haven't installed anything extra as of yet, so i will check on how to do that.

is this worth while?

Yes.

Code:

sudo apt install intel-opencl-icd

IMO, yes.  It increases tone mapping performance if you have HDR content.  Since you have limited tone mapping performance with your iGPU, you should ensure you get max performance from it if you have HDR content and SDR devices.

[chenks]

Code:

sudo apt install intel-opencl-icd

no probs.
intel-opencl-icd is already installed (in the ubuntu LXC), so that part is good to go

IMO, yes.  It increases tone mapping performance if you have HDR content.  Since you have limited tone mapping performance with your iGPU, you should ensure you get max performance from it if you have HDR content and SDR devices.

ok.
the doc says to install it on the host, which would be proxmox i guess
https://jellyfin.org/docs/general/admini...re-support

if that's the case then i would follow the debian set of instructions

althought the instructions say

The setup is not necessary unless you are using an Intel Jasper Lake or Elkhart Lake processor, or you want faster OpenCL tone-mapping speed on Linux.
This also applies to the bleeding edge hardware such as 12th Gen Intel processors, ARC GPU and newer but step 2 should be skipped.

my CPU is alder lake 12th gen, so not sure if that means that it isn't necessary for me or not?

[TheDreadPirate]

That line is saying that it setting up this firmware required for Jasper Lake and Elkhart Lake CPU.  Not just for tone mapping, but for transcoding in general.  It is optional for other Intel CPU families. But installing the firmware improves tone mapping performance.

[chenks]

ah ok, i'll need to read the installation instructions a bit more carefully as i don't want to end up screwing up the pve host in the process.

this is what my settings now look like (without doing the low-power for now)

[TheDreadPirate]

Also check "only generate images from key frames". Generating trickplays will happen MUCH quicker when that is enabled. The small loss in timing accuracy is worth it, IMO.

I also have an Alder Lake CPU with Jellyfin installed as a docker container on Debian. I have followed the thread and believe I've checked all the same boxes, but I'm seeing a lot of pausing/freezing/buffering during playback. It's much worse than just disabling the encoding/decoding. I do see, via the top command the CPU% is way down from when hardware acceleration is completely disabled, so there's that. I've included some playback information as well.

I'm struggling to understand how things could be different. If you want a new thread, I'm also happy to open one. Adding some of the information that was asked of OP in hopes there is something I've missed.

I noticed the information in the playback info had some progress noted on the transcoding progress. Once that completed, things seemed better. Is that a feature of sorts we need to wait for to complete to ensure smoother playback? Just from a user experience, that isn't the best, if you're trying to binge several episodes.
