Dolby Vision now possible through MP4 Mux.

Thanks for this.
To me there seems to be a slight tint change (so maybe whitebalance difference).
Would be pretty complicated to tell if it's just because the HDR10 version was encoded differently.

I asked @manix to provide lldv capture sample with his Shogun, this will be a more accurate way of comparing the colors/tint.

Thanks everybody.
Too difficult for me.
I surrender.

@quietvoid,
I get this error for the movie ''Soul'' no matter what I do. any idea why? Could it be because of the seamless branching disc? I tried to mux the m2ts parts with tsmuxer and mkvtoolnix, no difference.

Code: Select all

range end index 18446744073709551612 out of range for slice of length 1

Also, once the rpu is injected into an HDR10 hevc stream, if I use the mp4muxer, the frame rate goes from 23.976 to 30 fps
If I use Tsmuxer, no problem at all, the fps remain 23.976.

EDIT: the fps problem seems to be caused when the hdr10 stream is 23.976 instead of 23.976 (24000/1001)

The error happens when doing what? Injecting or extracting the RPU?

injecting...
if I use the same RPU and encode it with x265.exe, then no problem.

Ok, there's probably a bug or problem with the HEVC parser but it would be useful to have a backtrace.
I'll try to see if I can reproduce in the meantime, though the UHD BD sourced file I use might be different from yours.

If the error happens early, a trimmed sample could be useful.

Edit: I don't have an error on my side when injecting.

Thank you, I guess my bluray rip is somehow corrupted...

is this the version you have ?

Disc Title: Soul.2020.2160p.BluRay.HEVC.TrueHD.7.1.Atmos

No, I used an already remuxed file, which I don't think was done using MakeMKV.
Did you demux the HEVC straight from m2ts or used MakeMKV?

I could try remuxing the disc with MakeMKV myself but I can't find the exact same BDInfo as yours.

I demuxed the stream straight from the m2ts with tsmuxer.... I'll try FFmpeg and makemkv.

Since it's a disc with seamless branching, there's a necessary merge first but I'm not sure if something actually outputs the full video in m2ts.
I don't get an error when parsing the HEVC from a small m2ts at least (demuxed with tsMuxer).

If you can get a small sample that fails (for example when extracting RPU, even if there's no Dolby Vision), that's usable too.

[chros]

That's interesting what you talk about: can I add fake DoVi metadata (e.g. 1000 MDL, 1000 MaxCLL, 300 FALL) into a HDR10 stream, if so how?
(I want to create a small DoVi sample for FireStick 4k from a HDR10 sample to see whether it triggers tv-led or player-led with LG.)

Not currently but I'll make a tracking issue for it..

ok , I'll try to make a sample. Otherwise, I can give you a google drive link by PM of the whole ISO.
btw you can demux seamless branching discs straight from the mpls file with tsmuxer. perhaps that's the mistake I did.


EDIT: ok now this is strange... if I make a 1-minute sample, then no more error. but as soon as I'm working with the complete movie, the error comeback.

first is the complete movie, then the 1-minute sample.

Can you share the full RPU? The error doesn't seem to be related to the HEVC file..
