ok, I did more tests...

My previous picture was reporting EC3 because PLEX was configured to play the EC3 track while kodi was playing the DTSHD track. So I removed the DDP+ track just to be sure and now plex reports DTSHD and my AVR PCM and it sounds like 5.1 audio.

But one problem, if I play any DD DD+ track in bitstreaming, then my AVR get stuck in that mode and DTSHD no longer play.(I have to restart the AVR). This might have to do with the ''best match'' vs ''optimized'' kodi audio settings. And the FFMPEG EAC3 1536kbps tracks stutter just like on my x800 7.1 EAE encoded tracks are fine.

One more issue I think. Kodi also allows P7 ST rip to trigger DV but the RPU is ignored with my test file...

Hello, I stumbled upon issue, maybe someone here might be able to help me.

I want to convert 4K DV+HDR10 MKV into lower bitrate MP4 to play DV on my LG Plex.

Normally, when I only want to change the container from MKV to MP4 I just use
and all is nice and dandy. It triggers DV on my LG, but preservers the HDR10 metadata also, so all is OKay.

When I want to convert video stream I use: and it also copy all DV/HDR metadata, it even triggers Dolby Vision playback on TV (DV logo appears in the top right) but brightness is like in SD material. MediaInfoGUI claims all is okay. I lose HDR10+ but I do not care for that.

First is original MKV file:

converted MP4:


Any ideas whit it triggers DV but plays in low brightness?

Workflow 2-3

Very useful . I checked my almost 500 DV P8 movies and found that about 40% are Rpu 4000. Therefore I have created separate folders for them to be watched on the boxes mentioned earlier in this thread,
Thank you

But sometimes they do use the L2 trims to raise the brightness. The latest Mission Impossible flick is a good example.

So if I do want DV, Apple TV is a better choice than other players?
L2 trims typically are 100nits, 600nits, 1000nits. Does DV actually use L2 trims at all for 2000nits TV (assuming it will use 1000nits)?

whats the C2 mod???
I did not root my TV to enable DTS support if that is what you are referring to.

Yes, this one https://github.com/RootMyTV/RootMyTV.gi ... 1347543431

I just installed Kodi in Developer Mode and DV works just fine... and I'm out of the return period for my Zidoo too... damn it!

LE: And it also plays DV with DTS tracks and PGS subs just fine... This was everything I wanted, albeit, not a big fan of the Kodi interface, but could've saved myself $200 also, spent on the Z9X Pro

I'm not sure. When I force LLDV, they certainly don't work with a 1000nits edid + 1000 nits rpu but when I use the A95 1600nits TV-LED edid, they work but the image looks a bit strange.
Since the colorist can use the trims to raise brightness, it would make sense to always use them regardless of the display edid.

but yeah, the best you can do is to use a TV-LED device (atv shield or sony/oppo).

Seems I rejoiced too soon. Having issues with audio sync, even with non-DTS audio. Any tips on that? I don't use an AVR currently, I use a stereo system through optical connection. No issues with other sources.

no idea...

But on my end(non-rooted), I tried a 5.1 dts-hd channel test file and it's definitely only pcm 2.0 channels

Enabled pass-through and seems the issue is fixed for non-DTS tracks.

Does TrueHD Atmos break kodi on your end?
any lossless 7.1 audio(DTS-X/DTSHD/FLAC/PCM ) seem to cause the same issue for me.

No other issues on my end. Only issue is with DTS tracks sync and the endless Kodi scrapping, lol.

Damn. I thought this was a Plex issue, but it also happens on the x800. I went back and replaced my 1536kbps tracks with 768kbps tracks. Is there a better solution to this?

Reset if my tv lg oled e8 2018 900 nits , DV is ok with dune real vision ?

We can choose either TV or player led through menu settings on Oppo, on ATV there’s no settings. Is there a way to know that TV led is being used ?

Strange, they work fine on PLEX C2 and x700 but not on Kodi and x800m2.
1024kbps work btw and I added an option to specify the bitrate in the next dovi_scripts version.

Well, it's the player always processing the metadata but yes, it should be fine on 2016-2022 LG TVs.

The player should always use TV-LED when the TV supports both.
