Yes. But, as I said, it depends on how hard it will be to support Dolby Vision directly.

Apparently, from what I gather, a Blu-Ray stream with Dolby Vision stream also includes HDR10. So I should be able to support it as an HDR10 stream until I find out how to provide support for Dolby Vision.

Has anyone seen contradicting information?

Indeed it does.

I've carried out quite a few Dolby Vision detection tests using my LG television and OPPO UDP-203 playback devices and with most current muxing tools when you mux a HEVC stream with Dolby Vision into the .m2ts or .mkv container, the aforementioned hardware playback devices only detect/trigger the HDR10 layer.

BD Rebuilder v0.60.19

I've updated the first post of this thread with a link to the most recent release of BD Rebuilder. Changes for this release:
Code:
- Corrected "UHD_Correct_M2TS() 00009  8102"
  error that could be experienced on some
  high framecount BDs.
- Fixed "Can't open file:" error that can
  occur when attempting backup of sources
  with Dolby Vision.
- Added code to help support Dolby Vision, it
  is very experimental and needs much more
  testing.
- Other minor corrections and cosmetic fixes.

When you reported it a couple of days ago you said the error was "UHD_Correct_M2TS() 00006 8102". Are you sure it isn't error 00006?

Dolby Vision and HDR10 co-exist in the same stream.
If you omit the DV layer you still have HDR10.
Typical movie disc layout of m2ts

4K video layer, movie and HDR metadata
2K video layer, DV metadata
Sound
Subs
Etc

@ripem2011

Dolby Vision isn't supported yet. I have a few details on it, but not all that is needed. I probably won't work on it until I have standard UHD processing bug free.
yes thats what i am saying it kept the Dolby Vision file it shows both

You are correct. The error reported was:
08/06/19 [18:56:02] UHD_Correct_M2TS() 00006 8102

I'm wondeirng if it ever be possible to add hdr10+ metadata based on dolby vision to a stream, this would be somewhat of a game changer for those with hdr10+ TVs. My guess is that it be significantly harder to go in the opposite direction (hdr10+ to dolby vision), but who knows.

If I'm seeing it correctly, the HDR10 metadata is already there, stored in the same way as if it weren't Dolby Vision. I'm not sure how it changes with HDR10+. I don't have an HDR10+ source to dump/study.

Things are changing too fast... it's getting really hard to keep up.

Dolby Vision and HDR10+ are aditional 1080p layers
HDR10 metadata is integrated in the main HEVC

what Filipe said.

a UHD BluRay with HDR will have HDR in the main HEVC stream, but HDR10+ and dolby vision are additions on top of that to enable more dynamic HDR. The problem is it really depends on your TVs support. Most TVs that support dynamic HDR, only support Dolby Vision, while a few (notably all Samsung's) only support HDR10+. Basically a format war all over again.

It be nice if a mechanism was figured out to reauthor blurays to support both (especially if one can do it wiithout modifying the core HEVC stream), but have no clue if its possible.

I have some Dolby Vision (.ts and .mp4 contained) samples where the Dolby Vision meta-data is embedded within the HEVC video stream. And I also have some Dolby Vision samples where the Dolby Vision meta-data is placed within the .m2ts or .mp4 container as a separate stream.

So far all the Dolby Vision encoded discs I have have their Dolby Vision meta-data placed within the .m2ts container as separate stream.

By contrast, I have a couple of HDR10+ encoded discs and their HDR10+ meta-data is embedded within the HEVC video stream.

If people have some samples they would like testing I'm able to do this...

EDIT: Over on the Blu-ray.com forum there's this List of UHDs that contain Dolby Vision topic, which now contains information about whether the disc has been encoded using MEL (10-bit minimal enhancement layer) or FEL (12-bit full enhancement layer).



Cheers

Actually..... The newer ranges of Panasonic televisions and UHD players support both Dolby Vision and HDR10+

yes, but not available to US consumers I believe many players support both, but its the TV that really matters. The # of TVs that support both is very small (relative to the size of the market).

Sony was able to add Dolby Vision to their TVs, they have no intent to support HDR10+, but I sort of hope they add it if it gets significant market share

BD Rebuilder v0.60.20

I have updated the first post of this thread with a link to the most recent release of BD Rebuilder (v0.60.20). Changes for this version:
Code:
- Added code to work around the TSMUXER
  error: "Can't parse play list file" which
  appears to be associated with certain UHD
  MPLS files.
- Fixed an error in UHD audio extraction in
  which a "Failed to retrieve audio..."
  by TSMUXER message might appear.
- Added steps to audio/video extraction
  routines to try several demuxing methods
  before declaring failure.  Prompted by
  TSMUXER issues associated with UHD. 
- Fixed an issue that could prevent BD-RB
  from keeping originals when size permits
  while IVTC_1080P is set -- even when the 
  source was not 29.97fps.
- Added a check in automatic audio track 
  selection that prevents a mono or stereo
  stream from taking priorty over a multi-
  channel source just because it is a higher
  priority encoding technology.
- Made numerous changes in order to support 
  Dolby Vision sources. It needs considerable 
  testing and feedback, but has progressed 
  significantly.
- Other minor corrections and cosmetic fixes.
I would appreciate feedback on the Dolby Vision support. I don't have a player or monitor that supports Dolby Vision -- so your comments are the only way I know if it works properly.

It is indeed sad that Panasonic products are not readily available for you guys over in the US of A (you don't say where you're from by-the-way).

But good news for the two hundred or-so other countries in the world
