Dolby Vision now possible through MP4 Mux.

Hi all!

what am I doing wrong?

Did you start the other command window first, and you have that running?

[agneva]

The Ryan DV DL 07.06.mp4 did trigger DV in PLEX for my TCL tv. Looked Great. So did the mkv HDR10 file.
The Ryan DV SL 05.06.mp4 did trigger DV but the scene was almost all dark.

HDR10 should look right, the sky is very smooth
SL 05.06 should look wrong, too dark and the light sky is pumping.
DL 07.06 should look right, no pumping and very fine grain

On CX9LA internal player SL+DL is the same, because the internal player ignores EL.

Do you use Plex on your TCL TV internal ?

yeah, first window is ok.

Yes I use the plex app on the TCL TV. The mp4 works great. But when it comes to my friends DV MKV file. DV won't trigger. What I'd like to do is change the container to DV MP4. But I'm very new to this and don't know the steps to get to it. If its even possible to get to it.

Thanks for the sample files. I played them on my CX with internal player and HDR picture looked so much brighter, but DV (both profile 5 and 7) looked darker but the overall picture felt a bit sharper (and more detailed ) compared to HDR. Do you think only the internal player ignores EL? I tried with plex, but didn't find any difference between internal player and plex.

Is that an issue?

EDIT: I just played all 3 of your test files on my C9 (not CX). The DV SL file looks wrong with some kind of duplicated images overlaying each other. The DV DL file and the HDR10 file, however, play fine and look right. So there's sth wrong with the internal player of the CX since you said the DV DL and DV SL file look the same on your CX? That's surprising considering the CX is the newer model compared to the C9. I also heard someone say that was fixed in the latest firmware?

[agneva]

Of course there is an issue.

If you see the white sky is pumping / picture is to dark, the (F)EL is not decoded !

in my opinion the CX can only decode the Metadata (RPU) of DV, not the second HEVC stream.

maybe the older LG TV can do, I don´t know... to find out, I uploaded the samples for you.

Yeah my c9 plays the DV DL just fine.

Is your CX on the latest firmware?

[agneva]

with the firmware before it doesn´t play DV DL mp4

THIS !

MEL files look ok
FEL files look ultra dark.

I had a C7 before the CX and FEL files looked fine on the C7.

CX did not play DV (DTDL) mp4 prior to lastest firmware.

They do play NOW but as @Agneva pointed out, FEL files on CX look bad, too dark, as if EL was ignored alltogether.

That would explain the lack of support at launch.

Who knows maybe, the CX only has 1 decoder instead of the 2 required, would not surprise me, manufacturers undercut sucessfull product lines for profit all the time.

Have seen this happen a lot, a product gets fame for its quality and then next versions are cutdown for profit with inferior materials or features.

Maybe LG thougth no one would notice since streaming is MEL and that would really suck, i dont see much difference beetween DV MEL vs plain HDR + dynamic tonemaping or HDR10+, DV was about FEL.

Could very well be the case. Although I will say that the initial support for DTDL DV in mp4s on a smart tv has always been a bit odd. It could've just been a lucky coincidence with the early implementation of DV. Since FEL content is only found on bluray disks, TVs honestly have no need to have two decoders available for DV.

So I just compared the info of your DV SL file and a DV SL file I downloaded online. The difference is yours is Main10@5.1 while the other file is Main10@5.2. Your DV SL file looks wrong on my c9 but the other file looks correct. Does this mean anything?

Not sure exactly what the Main10 part means, but an obvious explanation for the difference you see in those two files you're comparing is that one is a from a native profile 5 source and the other is converted from a profile 7 disk. Given that there is no colorspace transformation during the conversion, it's not surprising that the resulting "profile 5" video might look wrong.

You are telling me, that Ryan DL.mp4 is playing correct on your CX ?

Ryan SL must look wrong because the EL is missing
SL is there to make a difference to DL version visible.
L5.1 is correct, like every Bluray.
Your Mandalorian is a pirated, reencoded copy you can tell the x265 encoder what ever you want, maybe L8.5:
