Ubuntu 24.04 & HW transcoding

Kaby-Gemini back on the table?

Great news! Thank you for your work!

@Menel

Kaby Lake is Back! :muscle:

GeminiLake is still suffering from Intel Media Driver :roll_eyes:
but we’re trying

EDIT: Turning tone mapping off works but that’s of little consequence on some films

It is because you have PGS subtitle burn in on. I believe I read that this is a work around. Try it without burning in subtitles.

Do you know if these fixes apply to Meteor Lake? I have a meteor lake server I’m willing to test on if you need volunteers.

I will ask the team lead and report back.
We do have a RaptorLake test machine and it works.

How about Comet Lake? Crossing fingers and toes

Kaby & Alder (Lake) are good.
Comet is in the middle. You should be fine.

Will all the gens have to be fixed before you release any updates?

Good news…thanks for your job
Is there any possibility to test ?

There’s unfortunately nothing I’m allowed to share at this point.
(there’s new stuff in this one as well … stuff we’ve wanted for some time)

Thanks for your feedback.
You rock guys.
Waiting for your next release and features

For those using Plex in an LXC, such as through Proxmox, would this new update still work with a 6.8 kernel, or would any other updates to the host need to be applied?

The beauty of the LXC makes this trivial :slight_smile:

  1. We’re on the 6.8 kernel, which the LXC shares
  2. We’re in the Ubuntu runtime OS virtualization / namespace
    (Proxmox is in the first namespace)
  3. As long as the hardware (/dev/dri) is passed through correctly,
    – PMS will bring all the updates it needs (user space) with it.

We will release for everything at once as we always do.

Right now, we are working through the QA cycle with some extra scrutiny because this is a big update to the transcoder and there’s a lot to test.
(we’re also updating the QA test documentation so they know what to test with each release moving forward)

Thanks for the updates @ChuckPa, looking forward to the beta release.

Great I’m waiting on this also… Spent a good few hours trying to fix this until I found this and it was an actual bug… running without HDR tone mapping enable and works great… awaiting the beta release for testing.

I’m assuming the tonemapping fix in the latest beta ( 1.40.3.8555) is unrelated and just sounds like the same problem, then (because it doesn’t fix anything)?

I have tested 1.40.3.8555 on JasperLake with Ubuntu 24.04 6.8 Linux kernel.

Tonemapping in HW is fully operational again.

I had hopes of HEVC encoding being fully operational for all platforms but I had forgotten that not all CPUs support HEVC encoding. oops on my part

Ah well bummer because like I said, it doesn’t do anything for me.

System: Arc A380 card, Ubuntu 24.04 with the 6.8.0-35-1 kernel.

Result: Installing the 1.40.3.85555 beta does not restore hardware transcoding tonemapping. Switching back to 6.5 kernel and installing the latest non-beta restores HW tonemapping.
