Hello,

I reported in May that there was an issue with playing Dolby Video files with fallback HDR since the May 11 nightly.

popcornmix replied at the time:
`````That is the last build before the reardonia patches were added to LE.

Those patches are a fairly significant rework of rendering (especially HDR).

The overlay (including subs) now goes through a SDR->HDR tonemapping path which is more expensive (although should produce better colours), although I'd expect that to only affect video when overlay is active (but maybe it's not disabled when not needed).

Thank you popcornmix as that seems to have been the issue and I am now happy to report that I have not changed or updated anything since then but had a look at latest nightly again today and it now works great again with this latest nightly:

 LibreELEC-RPi4.aarch64-13.0-nightly-20260708-b535a4a.img .

This is on a RASPI 4 FWIW many thanks for your development efforts. Much appreciated.

You've waffled ..

Ok, fair enough. This is your space and your call of course if you want to be rude and entitled.
I get it but also do not have to take part and am too old to accept dull snark from anyone these days.
Waffle on, be safe, be well.

Not reproducible by others. We have to see a log file.

Please provide a full debug log.

How to post a log (wiki)

1. Enable debugging in Settings>System Settings>Logging
2. Restart Kodi
3. Replicate the problem
4. Generate a log URL (do not post/upload logs to the forum)

use "Settings > LibreELEC > System > Paste system logs" or run "pastekodi" over SSH, then post the URL link

Understood. I have not seen anyone posting that they can play the specific testfiles I reported I can not play on any nightly after May 11 but that works on any nightly before that, but will stop here before I get more snark for my"waffle"
Many thanks.

MY ANSWERS IN ALL CAPS BELOW IN YOUR TEXT.

Is the non-smooth video blatant or subtle? Is it a frame drop every few seconds or multiple per second?

BLATANT, MANY FRAMES DROPPED AND CONSTANT micro-freezing.

Do the stats (ctrl-shift-o) show increasing skip: and drop: counts (note: a few skips when overlay appears is normal, but it should then no longer increment. Also this doesn't seem to catch all forms of skipped frames).

CAN'T TEST THAT ATM, NO KEYBOARD ATTACHED.

If you disable "Adjust display HDR mode" in settings/player/video does it make the video smooth (at the cost of incorrect colour)?

YES.

Does your display switch to a 4kp24 mode when playing 4kp24 video?

YES, AT LEAST ON MAY 11 NIGHTLY AND OLDER: NOT SURE WHAT IS GOING ON AT LATER NIGHTLIES

Can you confirm the have the following settings:

system/display "Set GUI resolution limit": 1080

YES

player/videos "Adjust display refresh rate" : "On start/stop"

YES

player/videos "Sync playback to display" : "Off"

YES

player/videos "Allow using DRM PRIME decoder" : "On"

YES

player/videos "Allow hardware acceleration with DRM PRIME" : "On"

YES

player/videos "PRIME Render Method" : "Direct to Plane"

That is the last build before the reardonia patches were added to LE.

That indeed sounds like a decent cause and correlation.
I am typically not using anything higher than 30fps.
I am travelling a bit this week but will try to get to the debug logs in good time.
May I ask if there is a possibility that our 8GB memory Raspi 4 will not be able to handle this new code?

Quote from MatteN

i use it on 4 Pi4 (2, 4 & 8GB) Pi5 (4/8GB) and some Intel boards.

Thanks. So do you play any large 4K HDR media files if I may ask?

Quote from Da Flex

houser Do you use sub-titles or any other type of display overlay?

Typically not, but this issue persists with or without subtitles switched on or off.

It also works without issues with subtitles switched on or off on LibreELEC-RPi4.aarch64-13.0-nightly-20260511-f6935c9

Quote from MatteN

I update almost daily and i dont see any problems.

Thanks. Could of course be something wrong here I guess, but the (causation / correlation) fact that it works perfectly with any build

before May 12 throws me. May I ask if you are on Raspi 4 also?

Hello,
Just curious, here the last nightly to play back smooth video is LibreELEC-RPi4.aarch64-13.0-nightly-20260511-f6935c9 which still runs perfectly.
Any version after that has issues with the 4K HDR stuff that we see much of.
Is this a known issue, a breaking change, or something we need to tweak?
Thanks for a great bit of code an any hints if there is time.

Have you tried using get_edid create?

Thanks! Might look into that if issue persists, was not aware of it.
Also did not have these issues before Omega.

It is by no means a biggie though to do a reboot also. Will experiment with other timings also.

Many thanks!

Raspi 4 now on Omega b1. Appears great and very stable. Many thanks!

Have been on the nightlies for a long time with very few issues so no surprise really.

The only issue i am still seeing is that sometimes HDR does not work after boot. A reboot fixes that, 100% repeatable.

Have tried delaying the start of the Raspi a while after the AVR but does not help so far. No biggie but reported FWIW.

Edit: some minor tweaks to the boot sequence in Home Assistant appears to have fixed it. So unlikely a LE issue.

11 Update channel still shows nightlies. Is that as it should? Many thanks again!

Just answering my own question if someone comes looking for that answer.

The nightlies went away when I switched off the " show custom channels" options.

Duh

Thanks for replies!

Did manual update to 10.95. Working as well.

11 Update channel still shows nightlies. Is that as it should? Many thanks again!

Hello

Have been successfully running the nightlies for a while without any issues. Works great here on Raspi4, many thanks!

Just wondering if it is now recommended to go to the 11beta1/10.95.0 or stay on the nightlies?

If we do want to go to the betas, what is the best and safest procedure? I do not see it in the 11 Update Channel?

As I can no longer select the 10 Update Channel, should we drop the:

https://releases.libreelec.tv/LibreELEC-RPi4.arm-10.95.0.img.gz

into the update folder/path via smb and reboot ?

Many thanks for any helpful hints!

Many thanks for your reply!

I can see on the TV that LE is sending HDR if I go into settings, so I do know it seems to be working and it looks great!

Some media files show that they are HDR or HDR 10, and some do not, even though they are and play fine as HDR.

I assume that is just lazy authoring of the media files.

Ah well.

Excellent and fabulous work! Happy holidays!

Hello,

Happy long time LE user here. Just upgraded to latest nightly Git: 20.0rc2-Nexus.

Working great! No issues at all so far. This is on a Raspi 4.

I am just curious about the new 4K HDR functionality. It seems to just work...

The only new setting I see is Settings/Player "Use display HDR capabilities" So is that it?
Is there any way to see if HDR is "engaged" ? "Show process" says nothing specifically about HDR.

Again, it looks great and I am very happy, just curious of intended functionality . Many thanks!

Seems very nice, I'm planning to get RPi4 2gb. What display you connect to your Pi ?

Yes, good times!. The Libreelec team really is rather impressive

As for gear I currently use a decent Sony Bravia 75".

I am a retired Home Theatre professional and have a small but well tuned hobby surround setup for my cinematic needs;)

I am currently using a Raspberry Pi 4 Model B with 8GB RAM. Got the big RAM as a precaution as the earlier

versions of Kodi made more demands on the RAM but the system report on the nightly I am using now:

LibreELEC-RPi4.arm-10.0-nightly-20210315-c5d7822

.. says I am using just under 700MB when playing full bandwidth 4K HDR so 2GB might be ok but I should maybe get the 4GB version if I were you if you can afford it.

Should perhaps also mention I have active optical HDMI cables as in my setup it would not work without it on a 4m run.

Good luck!

Very pleasantly surprised that this is already up and running.

Installed fresh and had a solid run today with no issues at all playing 4K HDR movies.

Fab work! Many thanks!
