To avoid causing alarm, can I suggest that the title of the thread is changed? Perhaps make it a solved question rather than an apparently incorrect assertion.

Apologies chewitt - wrong terminology and misunderstanding on my part.

Current nightly builds for x86-64 (Generic builds) are supporting HDR and it is sent to the display device so that any tone mapping would be done there. The current stable releases for x86-64 do their own tone mapping, which is not what you're looking for.
I also looked up your CPU - you are right. It's from 2015 and lacks the acceleration hardware needed for h.265. It depends on your budget and what else you need, but I am using a relatively low power Gemini Lake cpu and that is OK with 4k60 using h.256/HEVC, so there's no strict requirement to go for the latest silicon. One thing to watch out for is how the HDMI output is handled. Some NUCs, for example, have used an additional chip in the display driver circuit (known as an LSPCON chip) to allow the port on the box to reach HDMI 2.x standards. While they can work, success with LibreELEC is more likely if you can verify that your chosen solution does not use an LSPCON chip. -
x86 build with HDR support is here (build updated a couple of weeks ago) - LE11 HDR builds for Intel and AMD
It's what I used as my daily driver on Gemini Lake N5000. No stability issues as far as I am concerned.

Updated build in post #1.
Thanks for this.
Working nicely for me (MSI Cubi N with Gemini Lake N5000) - updated from your 06/18 build.
I notice that the VAAPI hardware acceleration for VC-1 is now working again too which is a nice bonus. -
Hi smp. Thanks for the build. However, I am sorry to report that I also get the ptp_kvm error on start up, and then the boot gets no further. I am running Gemini Lake Pentium N5000 if it's significant. I have reverted to the February 17 build in the meantime.
-
Cool! Many thanks. I look forward to playing with this.

We are asking for a more recent, updated build with the HDR patch.
OK - sorry - in that case I cannot help. This build works for me as far as my HDR needs are concerned, but I have nothing newer.
-
That’s the old build.
I guess you want this build from smp from February 17, 2022...
LibreELEC-Generic.x86_64-11.0-devel-20220217225924-720d9a5.img.gzShared with Dropboxwww.dropbox.comAs stated elsewhere - this is not my build, so I hope it's still OK to make it available.

I also use a mini-PC MSI Cubi N with Pentium N5000 (so one generation older than the N5105). It works very well with LibreELEC in my use case (mainly playing blu-ray and 4k blu-ray rips from my server).
I have an older one as well using Celeron N3060, and that's more than good enough for full-HD blu-ray rips but cannot do 4k rips (which require HEVC support).
Both devices are fanless and therefore completely silent. -
No worries. I can leave it there unless anyone objects. Since it's not my build, I am not sure of the correct etiquette in such a case.
-
OK, my apologies. I just figured you'd be looking for the latest. I do have some of the older ones stored. I'll need to see what I have got.
So here is what I believe to be an LE10 build by smp from 25th July.

Original post here... RE: Intel true 10bits/HEVC/HDR support... ?I have earlier ones as well, but see how you get on.

Did you try the link at the top of this thread...?

Direct streaming requires CPU power too? Sorry I am new to this
(My 4k UHD movies are mostly h.264)
Nothing is free, and something still has to decode the video and audio data and store it in a frame buffer and display it on the screen...
With a 4k image there are four times as many pixels to generate when decoding the data. Even with compression in the original data, there will still be more data to decode in the source data stream than for a 1080p file. And as mentioned, that Atom processor is very low power, even by Atom standards (it's also 8 years old). Regardless of that, you still have the problem of needing a driver for a suitable USB display adaptor - I very much doubt that exists in an easy to use form, and even if it existed, for LibreELEC you'd possibly have to build your own binary. In my view, it's just not worth it, given that there are other ready build solutions available.
As mentioned above, a Raspberry Pi 4 could easily do it. If you're only using h.264, you could also look at some other second-hand Intel solutions. For example, a Celeron N3060 can manage 4k @23.967 (and probably at 30 fps as well) with h.264, but absolutely cannot with h.265 since it lacks the hardware acceleration. Newer Intel CPUs (the Gemini Lake platform for example) are relatively affordable and can play full 4k UHD blu-ray rips without issue.
-
Also, according to Google, the PiPO X7 has a very low power Atom CPU from 2014 (Atom Z3736F) - probably very inadequate for 4K decoding from h.264 format, and a lot of 4K content uses h.265 which would need some hardware acceleration in the CPU (not present in this old Atom). I would also recommend a much newer device if you are serious about playing 4k content.

Go read post #2 again.
Also a good option, tbh, even if it's not Ryzen or Intel as requested.
-
I would suggest to avoid AMD for this. Intel, Gemini Lake is working well with test builds. I use Pentium Silver N5000 in an MSI Cubi N box with available test builds. Some newer devices are also working will in Intel NUC boxes, but even Gemini Lake is sufficient for the normal 4k MKV rips that I take from my UHD Blurays. I have no experience using Atmos, but I think that is now also supported.
See this thread... LE11 HDR builds for Intel and AMD
The mainstream builds from the LE download page are not yet supporting HDR on x86 platforms.
