Hi all, I have a small issue where upon turning on my TV/AVR (Pi is on 24/7), I have to change away from and back to the RPi source in order to get a signal. AVR is a Denon AVR-X 3600H.

If the RPi has been idle for sometime, and my Denon AVR starts up with the TV input selected (usually use the TV remote power button to turn on), changing to the RPi/LE source results in 'No Signal'.... I then change the source to something else, then back to the RPi/LE and I have signal. I have CEC enabled on the TV, AVR and the Pi. I usually use the TV's power button on remote to turn the TV and AVR on/off in one. Kodi will switch the AVR source and control volume via CEC, I understand it doesn't turn off or on with it though which is fine.

Any ideas what the cause of this is? A setting on the RPi? Or something on the Denon AVR? Its not the end of the world, but is slightly annoying and takes away from the 'slickness' of my living room media set up having to do the remote juggle.

UPDATE:

This issue still occurs even with a Pi5 running LE 12. Also, switching sources no longer appears to get me a display at 60Hz. Like others in this thread, I am able to get a 60Hz output, but once the AVR is turned off, when I turn it back on I will see no signal until the Rpi is rebooted.

I see that some with the AVR-X3800H report that AUX 1 and 2 inputs work fine @4K60, but all of the other inputs exhibit the same behaviour as above.

I can confirm on my AVR-X3600H, that the same is not true for my AUX 1 and 2 ports. They behave the same as the others.

RPi4/5 support HDR10, but not the dynamic version HDR10+ .. otherwise I agree

Sorry, thats what I meant.

To be fair, the difference between SDR content and 'base' HDR10 content is so massive that it makes me wonder if DV or HDR10+ is actually worth caring about at all.

The reason I started this thread is because I recently bought a £3K Sony 77" Bravia OLED TV and wanted to know if I am missing out on 'experience'.

Ive been a long time happy user of LE/Kodi on a Pi4 8GB. The audio/video support is second to NONE. The buffering/cache options are great for smoothing out the experience for non local content and it just works.

I started my journey with LE, with a USB HDD connected to the Pi4. I then changed to an FTP/S backend with a server (in a datacenter), but still with local library. Today I run a Jellyfin server on 13th Gen intel hardware with a massive drive array etc... in a datacenter and use the Jellyfin Kodi plugin to sync the libraries.

LE on a Pi4 in my experience DESTROYS everything else I have tried, including the Nvidia Shield TV Pro (which people rave on about)... Yes it does DV, but the hardware is dated, its underpowered and doesn't have enough RAM for high bitrate content.

I am awaiting delivery of a Pi 5 8GB which I plan to make my main media center system and retire the Pi4 to the bedroom.

In short.... There doesn't appear to be one single perfect device out there which supports everything.... But the best around in my opinion is certainly LibreElec on the Pi 4 (and hopefully 5).

No Dolby Vision or HDR10+? Meh.... I don't think im missing out on much at this point.

The fan in the Argon case is to noisy even at low speeds, i ditched mine and put on a Noctua 40 mm 5V connected to 3,3V GPIO, it spins all the time but its quiet and temp never goes over 40C.

Can you share details on the fan and your installation job?

Pi4 4GB with a Hifiberry or similar DAC HAT with RCA outs.

Job done.

Unless you have a fast Intel CPU device; leave it at the default (1080) setting.

Is this operating at 60fps?

Whats the correct settings for getting the UI to render at 1080p/60FPS when on a 4K TV?

I notice the bottom menu option says Unlimited/1080 > 30FPS.

What does this actually mean? Do I need to select that to go faster than 30 FPS? But won't that allow rendering at 4K?

This is already implemented via HDMI CEC. If I turn TV off, Kodi detects this via CEC and sends suspend signal to system immediately (no delay). Wakeup is much more complex, since it depends on SoC and its drivers. Whole procedure once worked on Allwinner SoCs (except R40), but wakeup via CEC is currently broken for some reason...

In other words, sleep part is already implemented, but you don't want it if wakeup part isn't implemented and here is the issue - only some platforms implements that.

Pi4 AFAIK doesn't have power management implemented in kernel.

This is correct, I have noticed that the system is suspended upon TV standby via HDMI CEC. But will not wake up, thus requiring a manual reset of the Pi4.

I take it the suspend function via CEC can be disabled via the CEC adapter in the peripherals menu?

You've probably built it on x64 workstation.

Their build system doesn't support cross-compiling, you have to build it on RPi4 running either PiOS or Ubuntu, 32bit because LibreElec still only supports 32bit userspace programs.

https://gitlab.com/DarkElvenAngel/argononed/-/issues/21

This is exactly what I’ve done. I’ll build it from a spare pi4 then.

The ones that we tested and confirmed to work are the following devices:

S922X:

Minix U22X-J
Ugoos AM6B

S905X4:

Homatics R4
Dune Homatics R4
Nokia 8010

RockTek G2

On S905X4 P7 FEL+MEL only work through libdovi and P8.1 conversion.

On the S922X we have P7 FEL support, but MEL doesn't currently work correctly.

Best overall?

It's obvious that having HDR10 support is better than not having HDR10 support at all.

And yes, the differences between HDR10 content and Dolby Vision content is a lot more nuanced than the difference between SDR and HDR.

But it doesn't mean that there's no discernible difference. I admit that most people, in most cases will not be able to tell the two formats apart (given say the same equipment and 2 versions of the same source material, one DV and the other HDR10). But again, it doesn't mean that there's no difference. In some cases there are noticeable improvements in DV content due to it being a dynamic metadata format.

Having DV support is often a matter of principle for people, who are (or at least consider themselves to be) videophiles. And no, being a videophile doesn't mean you have to buy expensive media players.

Adding DV support is non-trivial. It required a lot of work for us to get it working on CE on devices that have a DV enabled SoC.

But it's possible to have it on a Linux based device, albeit not on x86 and mainline kernel.

With all the above said, I think that none of the Pi boards support DV due to the licensing issue mentioned previously. Please correct me if I'm wrong on this.

Could you recommend some hardware for CE so I could try some DV content?

Ive been running LE on a Pi4 8GB for ages. Its excellent. I pre ordered a Pi5 8GB so can't wait to see if it increases the menu/UI performance.

Quote from chewitt

DV is encumbered by licensing and closed-source code needed to make things work. Kodi supports it on selected Android hardware like the nVidia shield and Firestick where the chip vendor paid-to-play and embedded the necessary stuff in the Android display pipeline; and support for DV is simply exposed to Kodi as a capability via the Android MediaCodec API.

None of the above happens on general purpose Linux or distros like LE because none of the moving parts are open-source and aside from a few scattered bits of boot and wireless firmware everyone middle-fingers closed source blobs and nobody will pay the licensing fees. The one possible exception you might look into is the latest OSMC Vero 5? box which is basically taking the Amlogic Android-Linux kernel (with all the needed codec support built-in) and perverting it for Linux/Kodi use. Go read the small print though; because I haven't and I'm only assuming it has support for DV media (but it likely does).

Thanks, this is what I thought anyway.

My experience with LE on the Pi4 has been so good with standard HDR10 content, I am struggling to feel like I might be missing out by not being able to play DV content. I always ensure my media is HDR10.

Am I really missing anything with DV compared to HDR10?

Quote from Da Flex

A license fee has to be payed for Dolby Vision, so Kodi will never support it.

Except Kodi does in v21 on Android no?

I guess you mean LibreElec on x86?

I’ve been a long time user of LE on a Pi4 and the experience has been excellent. 4K HDR10 with pass through of any audio stream, what more could I want?

I have one minor niggle that probably shouldn’t even be a niggle…. I’ve just got a new 77” Sony Bravia XR which supports Dolby Vision. Obviously no DV on a Pi, so I started researching other hardware options for Kodi on hardware that does support DV.

Which basically means Android…. I have used a firestick 4K max and Nvidia shield Pro but neither of them hold a candle to the Pi4 running LE.

So long story short…. Is the pi4 as good as it gets currently for Kodi on LE? I have a pi5 on pre order but literally the ONLY thing missing here is DV support.

Thanks

Click!

Original link broken, and the thread is just a wash with various modifications and fixes which do or don't work.

Not exactly what I'm looking for!

Thanks

Hi there,

I don't even think I need it as the passive cooling with the Argon One is so good.... But does anyone have an idiots foolproof guide to getting fan control working with LibreELEC in 2023?

Theres a mix of info about bodged modified scripts, a build your own daemon and various things out there..... But nothing clear and easy.

Anyone care to share?
