Dolby Vision

[Grencola]

While I'm waiting for the Atomic Blonde I did run few experiments with the Skyscraper. First of all TSMuxer extracted all tracks without any issues, which means that my MI:Fallout rip is definitely off. I managed to combine BL and EL+RPU into a single mp4 file, but unfortunately, not into a single video layer:

I can play the file with a Sony built-in video app, but it's recognized as HDR10.

That Skyscraper info looks just like my Atomic Blonde does (dvhe EL), which plays flawlessly on both LG and Vizio TV's, sorry for assuming Sony should be the same. As for your bad mi:fallout, running it through mkvmerge multiplexing should find/fix the errors on the fly and give you a TSMuxeR demuxable file.

I also ran single DV layer LG demos through a media info app and found the following:

Where the most interesting part is: Dolby Vision: 1.0, dvhe.05.09, BL+RPU

So I tried to repeat the conversion with a different profile (--dv-profile 5) and while I still got 2 video layers, the Dolby vision string looked very similar to that from LG demos (Dolby Vision: 1.0, dvhe.05.03, BL+RPU) and what is even more exciting a Sony built-in video app recognized it as DV! The bad thing is that video was so dim to the point of being unwatchable.

I'm wondering if it's possible to force mp4muxer to produce dvhe.05.09, BL+RPU.

I think mp4muxer has preset profiles to choose from as creating your own might require an official Dolby CMU? definitely try every little string you think could work though cuz if you get a single layer file running properly that opens up a plethora of device compatibility, MrMC included. although I still think if you crop a sample of your dual layer mp4 for them to test it might just play. I tried with TSMuxer but when I cropped the movie to 2mins long the output file had no 2nd video track anymore, so not sure what what program is required? you might have better luck

exciting times!

You can also add the dolby vision layer to MKVs... If you rip your legally purchased 4k bluray with Makemkv using the whole disk option, you can copy the main *.ts file into MKVtoolix and multiplex both video layers, and the Dolby Atmos tracks into a single MKV file. We just need to find someone who can figure out how to merge the two layers together.

when multiplexing your ts file it does add both the BL+EL video track, that's true. However, for some reason it applies the same profile for both layers so the EL also becomes [email protected] instead of dvhe, possibly stripping the dv out of it?

I compared the Dolby Vision tracks on both the Valerian 4k bluray .M2TS file, and the re-muxed *.MKV file. The profiles are the same, according to MediaInfo.

Exciting times, indeed!:) I will keep experimenting, but I'm afraid, as you mentioned earlier, creating a singe layer might require a Dolby CMU.

I'm note sure how I can cut a big file into peaces without loosing internal structures (layers/tracks).

the codec id changed though, which has me worried. I'll try making a couple mp4s from mkv and test them, but I have my doubts..

Hey, so the 2nd-gen Amazon Fire TV Stick 4k supports Dolby Vision in the same way the ATV 4k does (Netflix, Amazon Prime, Side-loaded Vudu apps, etc). Has anyone tried the LG DV test files using MrMC on it? I feel they may work as well.

Since these new mp4s can only do dd+ audio at best anyway, if they do indeed work with MrMC, one could save a hundred bux going with the FTV Stick 4k over ATV 4k.

There's a new build of x265 available (2.9+14) with the following changelog:

- added support for Dolby Vision profile 5
- added support for Dolby Vision RPU muxing (If given, x265's Dolby Vision metadata parser will fill the RPU field of input pictures with the metadata read from the file. The library will interleave access units with RPUs in the bitstream.)

Dunno what it means for the future.

AFAIK, level 5 means 4K resolution with a bit rate of 20-70 Mbps... fits 4K Blurays I would say. Dunno if that means x265 will fetch metadata from a 2nd HD stream or from within the stream itself, like the ATV.

Think it is referring to DV Profile 5 (ie single layer):

Pretty sure dvhe.05 is what Apple TV uses for Dolby Vision.

Hey, it is awesome to see all the advances about Dolby vision files.
I would like to know if someone can explain hot to mux my 3 files into one. I have read that Dolby MP4Remux should be used to so, but I don't know how to use that tool. It would be awesome if anybody can share a kind of well explained tutorial about this tool with pictures or a video.

kind regards.
