Yes, Tvheadend that was compiled for X11 version of LE doesn't work.

I compiled Tvheadend 4.2 and 4.3 that will work with my builds.

tvheadend42

tvheadend43

I did a bit more testing with the supplied tvheadend. I notice Deinterlacing is not available when using your build, most likely because it is not using VAAPI anymore. Is there a work-around for this ? Watching Live TV without deinterlacing is something which is a deal-breaker (too) - even more so than the lack of HDR

I did the test on the NUC6 for this, which I never use before, so it is possible it is related to the NUC6 - rather than your build.

did passthrough work on your NUC6?

Since it is raining figured I would go on with this

The NUC6 also supports Pass-through for me. I tested it with HDR file with BT2020 and True-HD passthrough popped up on the receiver.

Confirmed, tvheadend42 works - thanks again !

Unfortunately my NUC6 is not connected to my receiver . I will try and find some time to do that to test it. Since it is currently only connected to my TV I can't verify that yet

It did work on my NUC7 tho.

NUC6AYH has HDMI 2.0 port (MCDP2800 LSPCON), J3455 Apollo Lake SoC with Gen9 Graphics. It should be capable to support HDR in Linux.

Windows HDR support is irrelevant, Gemini Lake also doesn't support HDR in Windows.

Apologies for the later reply, bit limited in time and now it is weekend so now had some more time:

I can confirm NUC6AYH does work with HDR now with the latest build from RE: Intel true 10bits/HEVC/HDR support... ? (post 502)

I did a brief test on my NUC7i3 with the same build hooked up to my receiver - had to fiddle around a bit in the settings but I managed to get pass-through working (too). I had True-HD Audio and HDR working on it. I have not tested for long, because unfortunately the TVHeadend server on the build isnt working (requires a kernel-module which is not there - most likely due to the kernel-change?) and I needed to watch some TV

So all in all splendid work ! Lets hope this is a viable solution when the final release comes in for LibreElec 10

Just tested it and HDR still works

However 'allow passthrough' doesn't seem to work with this build. I can turn it on but but missing all the options like DTS, Dolby etc to turn it on/off. Didn't had an issue with the 1st build I tested. And when I restore my backup which I made from the first build it does work again. And I'm still on the same build version (*32b3089). I take it it shouldn't be an issue to restore my backup, right?

btw thanks for you help again.

I remember that if you need to set the options for the DTS, Dolby Digital, etc you need to turn on Advanced View. Perhaps you're still using Basic settings and then they are not visible ?

That's good news. You are the first one who reported a working HDR on older LSPCON hardware. It looks like that NUC has MegaChips MCDP2800BC LSPCON.

I uploaded an updated image.

- Linux kernel 5.12-rc4

- Kodi e04f7d6

Everything else is identical to a build from post #494.

NUC6AYH : No-go for HDR.

NUC7i3BN : Works with HDR (on the previous build you posted about roughly a week or two ago)

smp - forgive me if this has been beaten down before - but it is pretty hard to find information about the subject online. Your build, would it work on a NUC6CAYB to enable HDR output ?

The NUC6CAYB has a Celeron J3455 with Intel HD Graphics 500 and :

• HDMI 2.0 (4K @ 60 Hz) with HDMI CEC via MegaChips MCDP2800-BCT DisplayPort 1.2a to HDMI 2.0 Level Shifter/Protocol Converter

If memory serves me well it has the same LS-PCON as the newer generation NUC's have - tho I'm uncertain if the SoC can even support HDR.

With the Pioneer in the loop I get:
LPEIScreen 0: minimum 8 x 8, current 3840 x 2160, maximum 32767 x 32767
DP1 connected primary 3840x2160+0+0 (normal left inverted right x axis y axis) 1600mm x 900mm

720x400 70.08
DP2 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

and with this I get no image.

I did learn that if I set Kodi to 1920x1080p 60 Hz. with it directly connected to my TV and then switch the NUC to the HDMI on the receiver I get an image.

So it is somehow that the resolution set by Kodi during boot-up is not supported by my receiver for whatever reason. I guess I have to fix KODI to 1920x1080p but I noticed it has a tendency to reset occassionally... ugh

Do you have recommendations in how to fix this? Or do you need more information ?

I manually set the resolution during the test to 1920x1080. I generally run the Kodi GUI in 1920x1080p so that Kodi doesn't upscale everything to 4K (Kodi up-scaler sucks compared to what the TV does, imo).

However, when connected to the TV it can also run on 4K no problem. I just set it to 1920x1080p (which I want to do when connected "through" the receiver too).

Hardware:

NUC6CAYH PC with LibreElec 8.01 Generic installed
TV is a LG 49UH610V
Receiver is a Pioneer VRX-830

I get no video-image when I boot-up my NUC with LibreElec if my PC is connected to the receiver. I do get an image if I directly connect my NUC to the TV. Furthermore, when I installed Windows 10 on it I did get my screen working fine when the NUC was connected to the receiver.

I'm abit at a loss at what I can do. I imagine LibreElec is trying to set an unsupported resolution/refresh-rate or something when it is connected to the receiver, but I seem to unable to fix this.

Perhaps anyone has some pointers? I tried both the Generic LibreElec 8.01 and the one with HEVC265-10bit support with the 4.11 kernel. Neither gives a video-image on my setup. What gives? And more importantly, what can I do to resolve this strange situation.
