First of all, thanks for all the hard work everyone has put in on this. For me so far, I've been able to play 4k files w/ most audio formats (Atmos, DTS, DTA-MA, etc).
My one question is... has anyone been able to get 60 Hz/FPS using the the official raspberry pi HDMI cable? It says in their spec sheet for it that it's HDMI 2.0 complaint, but I'm starting to wonder. I've tried connecting my RPi4 to my AVR and directly to my TV, and I'm not able to select [email protected], and playback of any 4k content that is 60 FPS is slow, and not insync with the audio. Figured I'd ask here before i go and find a new cable on Amazon.
I've added "hdmi_enable_4kp60=1" to my config.txt file, and haven't seen any other lines that relate to [email protected] (connected via HDMI 0 on the RPi4)
"hdmi_enable_4kp60=1" isnt implemented yet in Beta 1. Maybe Beta 2
At the moment hyperion doesnt work with LE 10.
In my case i have to choose between Ambilight and HBR Audio.
I choose Ambilight
Switching back to fkms will bring back screen tearing, you loose HBR audio passthrough and HDR and you won't get any support from us. Other than that you are of course free to do that - just don't complain if things don't work
Ok, what pity!
I dont switch
no. hyperion(ng) doesn't have a grabber supporting GBM - see also here Raspberry Pi 4 with Libreelec v19 / Kodi Matrix, no grabber is working · Issue #983 · hyperion-project/hyperion.ng · GitHub
Ah ok, thanks for reply!
I was wondering why only effects are working
Hm, i hope there will be a solution. LE 10 without Ambilight is no option
i get no ambilight with LE 10 b1 and Hyperion ng on a Pi4.
Does it work?
Sorry for the late response, but it seems i have to wait 2000+ seconds to write another message...
Are you saying that if my TV has eARC (which it does) it doesn't work, or well doesn't send the signal?
With eARC you have DTS-HD or TrueHD.
In my case my TV doesnt have eARC (only ARC) and its no opinion for me.
Which one which support 4k60 and HDR?
I go optical from TV to AVR, and never had problems with HDCP. Maybe you have to setup your TV for this.
Audio over HDMI-1 is possible in theory, but a pretty new feature on LE. Better wait a couple of days until LE 10 arrives, then try again.
If you dont have a TV without eARC you cant passthrough DTS HD, Atmos etc.
Thats the reason why i sont use this
The Problem is ... how to find a 5m Micro HDMI Cable
I guess the first releases will come in near future. Im happy to test the first alpha of the Pi4.
For this good work i made a donation last week. Thanks, LE Team
I test this and it works particular (sometimes not correct HDR color representation)
But if i wirte in config hdmi_enable_4kp60=1 i get no pictures on my TV....
is it with LE 10 possible to use both HDMI slots?
In my case i need the first one to connect directly to my TV.
The second one only für Passthrough Audio to my Receiver.
(No, i dont want to use ARC cause just DD and DTS)
Is this possible?
If your AVR has HDMI 2.0 support but only supports HDCP 1.4 (and not HDCP 2.2) then that could mean it was one of the first gen UHD AVRs that had HDMI 1.4 inputs and outputs in hardware terms but that got very basic HDMI 2.0 support added (in the same way nVidia added HDMI 2.0 support to their HDMI 1.4 Graphics cards and Sony added HDMI 2.0 to existing HDMI 1.4 UHD TVs via a software upgrade)
The way they did this was to add support for just the 4:2:0 HDMI 2.0 mode for 2160p50 and 2160p60 modes - as HDMI 1.4b already supported 2160p23.976-30 at 8-bit in SDR using 4:4:4/RGB and 12-bit using 4:2:2 (though this mode may not have been supported).
Using the 4:2:0 subsampling introduced with HDMI 2.0 allowed HDMI 2.0 4:2:0 2160p50 and 60 modes to fit into the hardware restrictions of an HDMI 1.4b connection (i.e. you could add HDMI 2.0 basic compatibility using HDMI 1.4b hardware). AIUI this was 8-bit SDR only, and that may also have been true of the HDMI 1.4b 2160p30 and below support also supported. (i.e. you get UHD support at all frame rates in 8-bit, but you don't get HDR support as that would require 10 or 12-bit support - which may not be implemented)
The Pi 4B doesn't support 4:2:0 HDMI output as I understand it (as it would require both vertical and horizontal subsampling of chroma - and the Pi can only really do horizontal (?)
This may also mean your AVR is not HDR compatible ("passthrough" in AVRs isn't helpful in that regard)
The lack of HDCP 2.2 support is a strong suggestion that your AVR is one of those early HDMI 1.4 models that got a partial upgrade to HDMI 2.0 - though I may be wrong.
could be possible. It is a Denon X4100 Receiver.
HDR and HDCP are completely independent - RPi doesn't even have a certified trust path, so no widevine, HDCP etc.
my fault, i ask this not about Pi4. My AVR (Denon X4100) has HDMI 2.0 but only HDCP 1.4.
If i go from PI --> AVR --> TV i get no HDR.
If i go from PI --> TV i get HDR.
Is it not possible with HDCP 1.4 to get HDR?
I tried a HDCP Converter, but this doesnt work too.
Hias, the image that is tagged by its file on the above quote I just tried and I still don't have the hd audio formats ... although kodi on the TV has all the HD sudio formats (and the tagged build is the latest nightly build) any solutions?
Bro, there will be a fix.
Take a beer, make a donor to Libreelec, wait a little bit and be happy when the fix is ready for test
One question to all: Doe anybody knows, whether HDR is only available with HDCP 2.2? Is HDR passthrough not possible with HDCP 1.4 ?
