Dolby vision on LG G4 - LV948651 - 2025-01-11

Hi,

My setup is a htpc i3 12100 serving as both a server and a player, connected by hdmi to my lg g4 tv.
Server is running on windows with both latest version of the server itself and jellyfin media player.

I have the following file:

Code:
Beeld

Titel: 4K HEVC Dolby Vision Profile 7.6 (HDR10)

Codec: HEVC

AVC: No

Profiel: Main 10

Niveau: 153

Resolutie: 3840x2160

Beeldverhouding: 16:9

Anamorf: No

Geïnterlinieerd: No

Verversingssnelheid: 23.976025

Bitsnelheid: 68922 kbps

Bitdiepte: 10 bit

Beeldbereik: HDR

Bereiktype beeld: HDR10

DV-titel: Dolby Vision Profile 7.6 (HDR10)

DV-versie (major): 1

DV-versie (minor): 0

DV-profiel: 7

DV-niveau: 6

Voorinstelling DV-rpu: 1

Voorinstelling DV-el: 1

Voorinstelling DV-bl: 1

Id voor signaalcompatibiliteit DV-bl: 6

Kleurruimte: bt2020nc

Kleuroverdracht: smpte2084

Primaire kleuren: bt2020

Pixelformaat: yuv420p10le

Ref-frames: 1

Which it says is dolby vision, however, when it is played the dolby vision logo is not displayed and the tv does not recognise it as DV.
I read the lg g4 only recognises dolby vision from mp4 containers, but I haven't figured out how to remux to mp4 or if that's even possible/relevant.

I hope I'm missing something obvious. What could be the cause?
Thanks!

You can try...

Code:
ffmpeg -i "INFILE.mkv" -map 0:v:0 -map 0:a:0 -c copy "OUTFILE.mp4"

Replace the stream indices (last number in the -map calls) with whatever streams you desire. Note that MP4 does not support embedded subtitles. I'm also unsure whether Profile 7 is supported on LG TVs. Profile 8 is generally desired. The above should be a quick copy to MP4 and you can give that a try on your G4. I own a C1 and have had the same struggle. I don't do DV any longer, I honestly couldn't tell much of a difference.

Hi, thanks for your response. I have to apologize and have to ask where I input that code?

You would open a command prompt.

Code:
cd C:\Program Files\Jellyfin

ffmpeg.exe -i "C:\path\to\INFILE.mkv" -map 0:v:0 -map 0:a:0 -c copy "C:\OUTFILE.mp4"

On Windows, the correct Jellyfin path should be C:\Program Files\Jellyfin\Server\
Also, the c:\ drive is usually protected, so ensure your output is in another folder.

Code:
Run this from PowerShell:

cd 'C:\Program Files\Jellyfin\Server\'

then

.\ffmpeg.exe -i "C:\path\to\INFILE.mkv" -map 0:v:0 -map 0:a:0 -c copy "C:\temp\OUTFILE.mp4"
