Dolby Vision now possible through MP4 Mux.

[ATD555]

Is it normal for MediaInfo not to display the Dolby Vision metadata? Or am I missing something? No matter what video file I check it doesn't show the Dolby Vision info

[Grencola]

The resulting file showed up with the 2 DV layers and AC3+Atmos in mediainfo, but was not activating DV or Atmos at all on my 2019 Shield w/Plex or Kodi. Unfortunately I don't have a x700 to try it on, so not sure if the issue is with the file I generated or the Shield. My current set up is Shield -> denon x3600 -> LG B8

It's the shield. it doesn't support double layer dv. you need to use dvdfab to make a single layer mp4 and then convert that to TS. but apparently it doesn't play right on the shield. however, as I'm sure you've just read above, yusesope's new method for making single layer mp4s play in DV on the shield. so you could then use that mp4 to make a ts with atmos (which is all what my script would do) and hopefully be good to go.

[Grencola]

So as others have said the 05.06 profile works fine in Plex on the 2019 Shield - it would be great to be able to have a play around with the tool, especially as the start of Terminator is difficult to judge colours etc on.

are you able to use tsmuxer nightly to turn that mp4 file into a ts and add any old atmos track to see if it all works?

[yusesope]

Thanks for the tests guys.
I made changes based on your feedbacks.
Are you ready for the second round?
HERE you can find the new files (I also added the profile dvhe.08.06)

I think I'm onto something: I am also able to demux Single Layer DV files and transform them into Dual Layer DV files.
I made an attempt with the file you find HERE.
The result is this (HERE the DL file):

@Grencola
I am not using any other tools.
Just my code.
If it works, I can write the part of the program that accepts prompt commands based on your needs.

My tool accepts the Base and Enhancement layer as input (raw HEVC, for example BL.hevc and EL.hevc after a demuxing with ffmpeg) and returns a raw HEVC file in which all the levels are combined (BL_EL_RPU.hevc) .

The file can be imported as it is into tsMuxeR.
At the moment, however, tsMuxeR discards the EL level by returning an BL + RPU file.
You can test it with my files.
You should use ffmpeg:

Code: Select all

ffmmpeg -i my_test_file.mp4 -c copy my_raw_test_file.hevc

and then import my_raw_test_file.hevc in tsMuxeR

When I get the code fixed I will release the source code so you can play it as much as you like.

As for the problems with the colors and DVDFab, my idea is similar to that expressed on the Mrmc forum (HERE)

Ok sounds good, I'll see what I can come up with. Dolby's mp4demuxer probably works fine too to do get at the raw hevc.

[mattmarsden]

So do you think your tool is creating a DV file with correct colourspace etc?

[FusionNeo]

@yusesope

Good to see you posting and making incredible breakthroughs again. Happy to test, as before.

For your latest set of clips:

NVIDIA Shield Pro 2019:

All five files playback without issue and trigger Dolby Vision.

LG B7 Plex Client App:

All five files playback, both versions of dvhe.08.06 playback in HDR and not Dolby Vision, the other three files playback with the Dolby Vision icon.

I have no way of testing to see if this is true Dolby Vision, like has been achieved with the X700, or “pseudo-DV” like DVDFab’s implementation. I trust in your skills though so I’m optimistic it’s the former. If so, this is a massive breakthrough as it makes us one step closer to having the Shield Pro 2019 be the be all end all client capable of playing back all file formats... and it’ll stop me from having to buy an X700

Hi yusesope, I've been following this thread for a while now but just now created an account. I just tested these latest files on my 2019 Shield TV using the Plex app, and all play back fine. I also tested them on my OLED B9 through the native plex app, and all but 05.06 will play, all files pop the Dolby Vision logo. However, the new profile 08.06 v1 and v2 both playback much darker on the TV's Plex app for some reason, picture mode settings are the same across all inputs, so I'm not sure what's happening there. This is exciting stuff.

With your tool, would it be possible to mux in THD+Atmos/DTS:X?

This is very exciting stuff, keep up the great work! I'm happy to do more testing

[hepe9]

@yusesope there is one thing i don't understand, if you say you can create a SL DV with correct colors, in what affect the diferents version of DV?

At this moment the magic version is 5.06

If all have supposedly correct colors why try diferents versions of DV?

You have an approximate ETA?

Like FusionNeo say, if this is real and give us DV SL with correct colors is like magic

[ragico]

@yusesope
Your files copied to Hard disk connected to TV Panasonic GX

BL_EL_RPU_dvhe.04.06 trigger dolby vision but black screen
BL_EL_RPU_dvhe.05.06 trigger dolby vision OK
BL_EL_RPU_dvhe.07.06 trigger Hdr OK
BL_EL_RPU_dvhe.08.06_v1 and BL_EL_RPU_dvhe.08.06_v2 trigger dolby vision OK

[ATD555]

I will be testing the SL DV files on my Hisense H8F when I get home and post the results. Also curious to know how to make them myself.

[justinadams]

@yusesope
2019 Shield Pro
MrMC:only triggered DV on 05.06, all others only HDR10
MxPlayer Pro: all triggered DV

[ATD555]

So my Hisense H8F can play the Dual Layer DV files but they are showing a pink/green tint, anybody know what might be happening?

In TSMuxer I switched the order of the Enhancement Layer and the other layer and it plays perfectly on the Hisense H8F.

[DaMacFunkin]

So do you think your tool is creating a DV file with correct colourspace etc?

Hi, it isn’t color space it is color profile, UHD disks don’t contain the correct profile for the single layer Dolby Vision specification, as good as this news is it is conceivable that the resulting files are also incorrect.
