Which is great for SCALE but does not help anyone running the freebsd based CORE; those are two completely different operating systems.

This is very true, and, TrueNAS Core can only enable what is available in FreeBSD/Plex to begin with. And that's not very much. https://jira.ixsystems.com/browse/NAS-100255 was closed with "This is supported in TrueNAS SCALE. We cannot make it work on 12.", and that's just reality.

If you want to tilt at this windmill, it needs to start upstream. Get involved with FreeBSD Desktop devs, and with the Plex folk, and with Intel. It's quite the windmill to conquer.

For mere users: The pragmatic move is to go TrueNAS SCALE if hw transcode is compelling; or stick with Core and turn off hw transcode, and don't even think about it. Both are completely feasible.

I'll try SCALE perhaps when it is in beta but I'm not sanguine it will work for me and my Gemini Lake. The intel driver is broken; I have no difficulty invoking it in 12.

Hi I’m new to the world of Truenas but have done a ton of reading and research and have a general question.

I built myself a TrueNas core (12u1) NAS with a Xeon 2276g processor with a new motherboard with support for the embedded iGpu. I’ve turned on the option in the Bios to enable the embedded iGpu.

to get plex to utilize the embedded iGpu for transcoding, do I still need to follow the steps on the first page of this thread to get it enabled or has something changed that I need to follow?
Thanks for all of your help and for the wealth of knowledge captured here!

What I've got in TrueNAS 12-U1 is something strange and I cannot explain this. If I start the media with DTS and SRT hw (i915kms) transcoding the jail hangs the process with halting the resources to busy state. So the process cannot be killed, the jail cannot umount <jail>/dev and I have to restart the server as the only solution for this issue.

Can someone check if it's common problem, or just some local issues not linked to 12-U1 and hw transcoding? 12-RELEASE or 12-U1 without hw are working just fine.

- 12.1 broke subtitle hardware transcode, one of the real reasons to use 1080p to 1080p transcodes. No ETA on a fix. Software transcode in the meantime.

Looks like got the same problem. Yorick, did you had a chance to find any solution?

I'm having the issue on 12-U1, where when using hw transcoding the process hangs completely and I'm unable to restart the process without a whole server reboot. Let me know if you find a solution...

@Yorick - Just found this thread, and reading your great posts!
I do have one question in regards to my setup, it's the same processor that @m0t0rh3ad has with the ID: 8086:3e98 (Intel i5-9600k)
running the lspci -nn command shows:

00:02.0 VGA compatible controller [0300]: Intel Corporation UHD Graphics 630 (Desktop 9 Series) [8086:3e98] (rev 02)

You had stated this was a partial refresh in the CFL:
>Let's call that confirmed: ix-9xxx CFL Refresh use [8086:3e98] and aren't supported in FreeBSD 12.x.

So were just playing a waiting game for either drm-kmod package to be updated, or FreeBSD 13.x?

On 20.10: Everyone
On 20.12: No one (or risk update issues in the future)
On 21.02: Everyone again (afaik(

Yorick · Jan 17, 2021

TrueNAS SCALE or TrueNAS Core based on FreeBSD 13 ... one of those will be ready to deploy sooner than the other.

So, it no sense to spend time finding out why is HW Transcoding not working in Plex with NVidia card in Docker on TrueNAS Scale 20.12?
I can see the card in TrueNAS, I've got docker "nvidia-device-plugin-daemonset-4n5r8", Plex Docker also deployed with Environment Variables: NVIDIA_VISIBLE_DEVICES - all, NVIDIA_DRIVER_CAPABILITIES - all, and I can see NVidia card in Docker running command NVIDIA-SMI... but HW Transcoding not working :(

Yes, because it's a known issue with NVIDIA drivers. No limited to scale, it really doesn't require investigation.
It's solvable, just not without an update.

Just a minor oversight when IX updated the kernel without testing NVIDIA

Nope, Intel drivers in TrueNAS 12.0 are not updated yet, so you have to turn off Hardware Video Encoding feature (decoding is ok).

I have just build new machine as per my signature (system 1). I checked all compatibility for HW acceleration with https://github.com/kern2011/Freenas-Quicksync And the board,chipset and processor all check out
I've followed the guide for enabling internal graphics https://ahelpme.com/servers/supermicro/enable-internal-graphics-in-supermicro-servers/
My Truenas core 12.0 U2.1 is installed in UEFI mode and this is set in the bios
I have not installed pool or run Plex script yet.
The output of the lspci command is:

root@truenas[~]# lspci

I dont see the display controller. But I am a novice.
I really do need help here after spending money and time getting this particular configuration to try and get HW acceleration working.
Thanks in advance
