I have a new Mecool KM2 Plus Deluxe and it does NOT play HDR 10 or HDR 10+. I also have a Dune HD Homatics Box R 4K Plus with same/similar specs. The Dune plays everything perfectly under Kodi.
I tried to compare logs, but all the errors that I see on the Mecool box refers to "sink" device. Here are the logs for both devices.
Any suggestions??

thanks

Can you redo the debug log for the Mecool device with debug enabled before you start Kodi?
It's missing the detected display HDR capabilities.

Alternatively you can see them under System/Video I think.

Will this one work? https://paste.kodi.tv/amokejelak

Yes, it does say

Quote:CAndroidUtils: Display supported HDR types: Dolby Vision HDR10 HLG HDR10+

So the rest is up to the device to play HDR10+ properly.

I don't think Kodi can do anything about it.

What does that mean?

I have seen several reports that the device doesn't support HDR.

It is suppose to support HDR 10 and HDR 10+. Got an email from tech support showing me a photo of their monitor (TV) displaying HDR 10+. I have been emailing their tech support with logs and videos of issues of there box not working with HDR. Dolby Vision works great under Kodi on their box.

Mecool has acknowledged the HDR issue with the KM2 Plus Deluxe. They have just communicated that a firmware update will be released sometime next week to address the problem. Keeping my fingers crossed.

As a follow-up, I've just received an update (kernel version 5.4.210) after a restart and HDR is working fine now.

Thank you for the status update. I just checked and I also had the update.
The HDR 10 and HDR 10+ are now working. Using Kodi, version kodi-20240114, I get no audio at all when the DTS versions as the sound track. Any suggestions on the audio settings to get audio??

I am doing a factory reset, since after a major update, I like to start clean.

After a clean install, I installed the latest Kodi development build. Again, HDR 10 and HDR 10+ are working as it should, but audio is still PCM and not working very well.

Removed the development build and installed the Google store version. Same issue with audio. ONLY stereo..

Emby has to transcode the audio, but plays perfectly.

Please post a full debug log (wiki) as our crystal ball isn't working right now.

Thanks.

Here is the log... https://paste.kodi.tv/direyerupe.
I am not sure what audio codec this Mecool KM2 Plus Deluxe supports. I have tried multiple settings, but same issue.

Strange, when I ply a Dolby Vision with Atoms video, using the included Netflix app, it plays perfectly with DV AND Dolby Atmos......

Edit: I tested two movies, one with TrueHD and one with DTS-HD....... Seems like I am only getting stereo.

Well, from your log, your device does not support DTSDHD_MA or TRUEHD.

FFMPEG opens a truehd decoder, but then it can't find an output - not surprising if that format isn't supported by your device. so it ends up opening stereo output.

Thank you for confirming my suspicion that Truehd is not supported. I will report to their techs.
Is there a setting in Kodi to get at least Dolby Digital??

**fritsch** · 2024-01-25, 20:51

Yes. Set PCM channels to 2 (!)
Under passthrough enable AC3 and Dolby Transcoding.
