Alright, i will. Thanks for the info, bud. I was not aware of any issues with x86. So know i at least know where not to look. I'm sure i'll find the fix. Librelec never lets me down. It's awesome. Will post the fix when i find it.

Hello there,

I have been running libreelev forever. Currently my main libreleec is on an Odroid H4+ with N97 chipset, attached to a 4K tv and Atmos surround system. Because i have been using kodi for a long time i have a massive library of various content, alot of old SD/HD files, and a bunch of newer 4K HEVC stuff.

The problem i am encountering on the odroid recently, is when i enable DRM prime, and start any HEVC content, the sound will play but the the screen will hang or blank, while the seek bar will still allow me to scroll through the file. The audio will skip accordingly but the screen will remain blanked and glitchy.

When i then disable DRM Prime, the 4k HEVC content will play just fine

But then the older SD/HD content, mostly mpeg4 files i made back in the day from old tv recordings, will either show a solid green screen whilst playing the audio, or a screen with green/pink/purple washed out colors, with two duplicates of the image side by side on the top of the screen, partially obscuring the full sized image on the screen.

I have tried disabling and enabling 'Allow using DRM PRIME decoder (both with and without 'allow hardware accelleration' enabled, and with 'prefer VAAPI render method enabled or disabled. I have also tried turning off 'use MPEG-2 VAAPI' and 'use MPEG-4 VAAPI'. But whatever combination of these settings i use, it will either not play the old SD content correctly with the green screens, or it will not start HEVC 4K video.

However on my Raspberry Pi5, hooked up to a 1080P monitor, i can switch between content and it will play old and new 4K HEVC content just fine on the 1080p screen. But the Pi5 does not have the VAAPI options in it, it seemingly only has the option for DRM PRIME.

Is there any way to make librelec on an N97 chipset correctly switch between DRM PRIME and VAAPI? Or another option to enable it to play all content i throw at it without having to change the render settings every time i switch from HEVC 4K content to SD content?

Thanks in advance for any help.

I have an Odroid H4, with a spacious M.2 SSD, set up in a triple boot situation off the one disk, following manuals made by better minds than mine. It was a bit fidgetty but fairly straightforward in the end.
(first installed ubuntu, leaving room on disk, installed windows, still leaving some room on disk, reinstalled ubuntu over itself to fix bootloader, and then copied the libreelec partitions from an image of a working install on the machine into the empty space at the end of the disk, and finally hacked the grub bootloader in ubuntu to add libreelec and put it on top (where it belongs :), with windows as second option and ubuntu as third).

I have a kodi install auto starting in windows as well, so switching from LE to windows-kodi is seemless. And all my libreelec and kodi installs in the house share a library and highly customized minimal interface (arctic zephyr ftw) for a seemless user experience on all devices.

When i reboot the machine, grub auto boots into the top option LibreElec in 4 seconds. But if i want to reboot into the second (windows) or third (ubuntu) i have to make like a bomb disposal squad to find my keyboard to make the grub selection. When i reboot from Windows i dont have this issue because it autoboots to libreelec, and i know there are ways to tell ubuntu which grub option to boot into before rebooting.

Is there any way to add an option to boot into a second or third OS from the shutdown menu or thought some shortcut in LibreElec? So i can make the choice before rebooting and bypass the grub bootloaders detonation timer? Thanks in advance for any hints to achieve this.

In the end i also dropped the pi, and am now running an odroid h4 hooked up to the Denon. It has no issues with 4k60hz on Libreelec. And is not an issue on windows or ubuntu for the H4 either.

I can confirm this same problem occuring on my Denon x4700h. I have it hooked up to a Samsung UE55KS8000, and a raspberry pi5 with libreelec on it. It seems Denon does not agree with the Pi 5's take on 4k60hz resolutions.

When the pi5 resolution is set to 4k60hz i get no display though the Denon on any of the HDMI inputs. Tried 3 different cables. When i plug the pi directly into the tv, 4k60 works smoothly with HDR, so it is definately an issue with the Denon AVR. When i set it to 4k30 the denon will display the pi5's output, but the image quality seemed off, possibly an issue with HDR. I will need to do some more troubleshooting on this.

My current workaround is that i have hooked up the pi 5 HDMI output directly into the TV, and looped an SP/DIF optical cable back from the TV to the Denon AVR. Having activated HDMI CEC on all three devices i can still have the pi5 wake and shut down both the avr and tv. Only downsides are two cables running across the wall to the TV, and the whole HDMI feature on my AVR being bypassed, making switching to different sources besides the pi a bit more of a hassle.
