I tried another similar file Downloads Page - Demolandia but that one stuttered too. I thought it might have been my NAS so played it locally from a USB; was smoother but still jumped around.
Yes, this is to be expected 4kp50/60 files won't play smooth.

-As someone mentioned before, DD+ pass-through doesn't work (but when disabled soundbar outputs as PCM)
-High frame rate (60 fps) videos don't work (memory issue or not supported yet? My settings perhaps?)
like the sony sword one: Sony: Swordsmith HDR UHD 4K Demo | 4K Media
DD+ passthrough is broken in kodi Garbled sound with DD+/EAC3 passthrough and official Dolby DD+ 7.1 sample · Issue #19182 · xbmc/xbmc · GitHub so leave that disabled
I could play back Sony Swordsmith here, so it would be good if you could post a "pastekodi" log.
50/60fps UHD is quite problematic though. The video driver can't output 4kp50/60 yet and the HEVC decoder in the RPi is also struggling with these files - player debug overlay shows that A/V sync is climbing up. 4kp24/30 files generally work fine though.

Display MorePassthrough is working well except on videos with 7.1 audio. I'm using passthrough via optical to a Marantz SR55000 receiver 5.1 speaker system. The media is HEVC 10 bit derived from a BlueRay. The Dolby 7.1 audio is being detected as a stereo audio source by the Amp. The voices in the video are mapped to the a surround channel and a barely audible. Media Info says the 8 channel mapping is "Channel layout : C L R Ls Rs Lb Rb LFE.
Media Info Audio.
Audio
ID : 2
Format : AAC LC
Format/Info : Advanced Audio Codec Low Complexity
With optical out only AC3 and DTS passthrough is supported. The mediainfo shows it's not a dolby digital but an AAC audio track - that can't be passed through at all, you have to enable AC3 transcoding (then kodi will transcode AAC to AC3 and you get 5.1 sound with your receiver).

The preferred and easiest way to post logs is to either use the upload logfile option in LibreELEC settings or to ssh into the RPi and enter "pastekodi".
Both variants will give you an URL, just post that URL here.

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 ?
HDR and HDCP are completely independent - RPi doesn't even have a certified trust path, so no widevine, HDCP etc.

RPi4 doesn't support 1366x768, see the official documentation Raspberry Pi 4 HDMI pipeline - Raspberry Pi Documentation
Try the workaround from there or just search for "RPi4 1366x768" and you'll find plenty of info and other possible workarounds.

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?
No. As I already wrote 2 times, here RE: RPi4 testbuild with HDR support and here RE: RPi4 testbuild with HDR support there is no fix/solution available yet to get HD audio with your TV.
so long,
Hias
FYI: the HDR and HD audio changes of these testbuilds are now in LE master and included in the latest nightly build, so you can switch back to using nightlies.
It'll probably take a while until the colorspace and bit-depth issues are fixed, I'll report back when we've got something new to test.

Hias
The fix hasn't been written yet...

master/nighly is missing 2 commits from the latest testbuilds which further reduce the chance of audio dropouts - I'll include them in the next RPi kernel update.

http://ix.io/2PAw this is it, thank you in advance because this problem is fraustrating since the odi on android tv supports dolby atmos and dts hd and eac3 but on this libreelec build and the other libreelec build cant get thse formats
Thanks for the edid, this is a bug in the linux kernel's EDID passthrough format detection - I recently ran into that as well. I'll have a look if/how we can fix that.

linuxuser run this command on your RPi, then post the URL you got:
od -t x1 /sys/class/drm/card0-HDMI-A-1/edid | pastebinitcopy-and-paste that into putty/ssh and make sure all is in one line and exactly as above.

Hi again , do I need to grab this file from the tv or from the Raspberry pi 4? Thank you and also I tried but it says -sh edid.dat : not found
Use putty to connect to your RPi, enter that command, then use eg filezilla to copy the edid.dat file to your PC.
As an alternative you can run the following command via putty:
cat /sys/class/drm/card0-HDMI-A-1/edid > /storage/videos/edid.datthen you can get to the edid.dat file via the "Videos" samba/windows share.
Edit: if you are using linux then use ssh root@IP-OF-YOUR-RPI instead of putty and "scp root@IP-OF-YOUR-RPI:~/edid.dat ." instead of filezilla.
so long,
Hias
linuxuser can you please grab the edid of your TV and upload it? Run
cat /sys/class/drm/card0-HDMI-A-1/edid > edid.datthen upload edid.dat (you may need to ZIP it so attaching works in the forum software).

Hias
Yes. RPi4 uses the ARMv8 addons, RPi2 the ARMv7 ones.

noggin thanks a lot for testing, this is in line with my suspicion (video driver using the wrong transformation matrix). Not 100% sure why 10/12bit output isn't automatically enabled, could be that we need to explicitly request it.
Regarding subsequent playback issues: Which testbuild did you use? The one from the first post (from Feb 5) or the one from here RE: RPi4 testbuild with HDR support (Feb 10)? The later build contains some important fixes that may be related.
If you got that issue with the newer build please post a log (ssh in, run "pastekodi" and post the URL) and ideally a link to a sample file so I can try to reproduce that locally.

Hi, I have a question how the dolby atmos pass-through works on this libreelec version? Like I have a tv that's is certified dolby atmoa device, if I play some videos that have dolby atmos audio how the audio will be flagged? And will I get audio when I have audio pass-through enabled and play dolby atmos files? Thank you in advance , continue the amazing work
You have to change settings level to "Expert", then tick Atmos (and whatever other formats your receiver supports) in the "passthrough" section of settings->system->audio.
Kodi doesn't query the devices capabilites so you have to select formats manually. Note that DD+/E-AC3 passthrough in kodi is buggy, so better keep that disabled. DD/AC3, DTS HD and Atmos should all work fine.

Hias
