Hi everyone newbie to Coreelec (not Libreelec)

Ok so recently I upgraded my player to a Dune HD ProVision 4k

I have successfully loaded Coreelec onto and SD card and loading it successfully : current details are as follows

21.2-Omega_nightly_20251023 Linux version 4.9.269

I followed the Ronnie utube method ( the upload vid was 12 months old) to load it and included the yada yada dovi.ko file from this thread from March 2024 in the initial loading of Coreelec as per the ronnie instructions.

When I go to the Corelec video setting I don’t see the Dolby Vision options.

What have I done wrong?

Where do I need to check that the dovi.ko file is? and have I used the correct file?

Thanks

You need the correct doki.ko and a DV capable device, otherwise, the option will not be displayed.

Better to supply logs to see if the correct dovi.ko is loaded successfully :slight_smile:

Thanks for the reply the end display (after passthru a Maranzt SR 7010) is a Sony KD-75X8500C (which doesn’t have FEL). It has DV MEL, but not FEL but if the file is correct and in the right place I would still see it as MEL (not FEL) …correct?

972

I’m not enough expert to answer you, Maranzt SR 7010 is compatible DV right ?

973

Yes. I believe so… It has a passthru setting to allow pass thru of all video signals..

974

I did a quick search and I don’t think either of those (TV/amp) support DV.

975

Ok cool. So if they don’t support it, I won’t see the two options Disable Dolby Vision Support and Use player LED under Settings/System Coreelec (even though my instance of CoreElec might be set up correctly). Is that a correct statement?

You need to have both a compatible receiver and TV in the HDMI chain to see these Coreelec options?

976

I can SMB into the Coreelec instance. How do I check 1/ I have the correct doki.ko file and 2/ What folder do I put it in?

977

Correct the DV menu options only show if both 1) the dovi.ko is loaded and 2) the HDMI connected device reports that it supports DV.

The first post is still correct in terms of the possible locations for placing the dovi.ko.

978

Quick question?

You are using Default Estuary Skin? ,Set to Expert?

979

Yep. Set to expert… gdam thanks to yada yada’s awesome work I am going to have to upgrade my TV and receiver!

I am struggling with a Homatics Box R 4K Plus. I am trying various builds and settings in the GUI but there’s a lot of frame freezes. Can you please share your config?

Using Homatics Box R 4K Plus with NG 21.3 + dovi.ko and I can display “This device can decode FEL” properly on FEL test videos, why it said Homatics does not support FEL?

983

Who does say this? It’s just not true. But only by CE-NG.

984

Here is the post which I can find, I remember much more but could not find for now:

985

Old info (Mar 2024), some things change over time, that is what time can do :wink:

986

Indeed, that is what I thouhgt. :smiley:

Will it be enouhg to say it is fully working with those tiny test videos or should I download DV ISO to test FEL 7 ?

987

Hi, do you mean if I use a SDR only projector, it dose not support DV? I install NG 21.3 and copy dovi.ko in same directory with dtb.img. I can’t see DV options under Settings / System / CoreELEC, and no women see when I play test file.

988

Yes, if the projector EDID doesn’t report DV support, then no DV options are shown in CE settings.

989

Bro, I’ve seen a lot of claims like this about the Dune or Normal Homatics Box R 4K Plus, but the thing is—it actually handles FEL perfectly. I’ve watched multiple Dolby Vision Profile 7 movies, even huge ones around 110 GB, and they played completely smooth. Just pair it with a good SSD like the Samsung T7 and it performs insanely fast. i played BDMV Files, all blu-ray Remuxes perfectly fine.
