Oh yes I meant to ask - is it possible to transcode a TrueHD track to high bitrate DD+ (i.e. eAC3) and include that inside a dual layer DV MP4? Or does it have to be AC3?

I’ve just realised you can include a e-AC3 track when creating the dual layer MP4 using Dolby’s mp4base.

I thought it’s quite easy to convert a TrueHD track to e-AC3 using ffmpeg. Curious why you suggested xrecode? It seems pay for software so I guess it brings something to the table.

@ RESET_9999 have you managed to get Atmos to work on a Shield using SL DV? I've tried numerous ways but it's just not working playing on my shield, it is also jerky until I choose a normal ac3 track. I'm either doing something really wrong or plex just doesn't like the atmos track.

No, I saw you trying before me so I did not try because I have to install the trial version (or find a cracked version).
and since SL DV are probably not real, I didn't bother too much...

I'm mostly interested in screenshot comparison from TS DL DV vs DL DV MP4 vs UHD-BD DV. I'll try to do it tonight if I get a chance but I doubt it.. will have to wait for the weekend

I think I'll give up on the SL for now and let somebody else try, I'll happily try any samples but I'm having no luck at all on the shield sadly.

Edit: On the X700 the SL DV plays with DV and Atmos triggered, running from a hard drive rather than over the network.

P.S. - SL looks pretty awesome on the X700 to my eyes

I wonder how well an mkv remux would work in a ts container. I know dv mp4s made from mkv's would have the odd hiccup, perhaps that's resolved using ts.
eac3to and gMKVExtractGUI can easily get you the 2 hevc video tracks and the thd atmos audio track which then gets added to tsmuxer nightly just like an m2ts. I bet it works great.
note: adding an mkv remux directly to tsmuxer usually brings upon errors that certain tracks are skipped, and it's usually the thd track. but it's always good practice to try it first and see, cuz if the tracks you want show up then it saves you time.

Hi there - is it the case now that the tsMuxeR nightly can create a dual layer DV m2ts file from an mkv?

I ask because I might have tried yesterday and it didn’t work. Or atleas there was no “Dolby Vision” written anywhere in mediainfo. Although I was jumping between different tsMuxeR builds, so I’ll definitely double check if you believe this should now work?

Would there be anything special to do - like first extracting the two DV layers before inputting then into tsMuxeR? Or just try opening the mkv in tsMuxeR directly. I don’t care about the audio for a proof of principle here. If this can create dual layer DVs it opens up lots of possibilities.

I’ll definitely try this later if you think it would work.

I just tried going from mkv -> m2ts directly using the 2020-02-25--01-10-33 (Mac) nightly build of tsMuxeR. Just selecting two video layers from the mkv and nothing else. And selecting "Blu-ray folder" for the output.

I don't think it worked since there is no mention of Dolby Vision from mediainfo (unlike with @RESET_9999's example above):

It doesn't do m2ts but does do ts, the ts works fine on the X700 bluray player from a usb hard drive, it's a pretty huge breakthrough

Thank you! I just tried again selecting "ts" as the output for tsMuxeR.

And now MediaInfo says "Dolby Vision" :-). Again - this is going direct from mkv. I won't get excited just yet since will have to wait until tonight to actually try playing it and see if it's choppy etc. But trying just now in VLC on my MacBook Pro - nothing seemed obviously wrong (although there is no

A quick question for the experts, if I remux my m2ts files from a UHD disc to ts can I reverse the process? i.e. using ts muxer to convert the ts back to m2ts will it be exactly the same as the original and work in the UHD disc? I'd rather not keep two copies of the files and waste hard drive space or have to re-rip my UHD discs again when needed.

yes, you can revert back to m2ts, ISO or bluray structure.

Hello everyone!
I am happy to see that there have been developments.
I haven't tried the new method (tsMuxeR) yet but it looks promising.

Not to be outdone, MAYBE, I found a way to combine the base layer, the enhancement layer (both MEL and FEL) and RPU metadata in a single layer from a dual layer Blu-ray disc.

I did some tests with the latest Terminator (BL on one layer and FEL + RPU on the other)

and HERE you can find some test files.


I have created a custom tool (for now, a bunch of disorganized lines of code) and , without using DVDFab, these are the results (files without audio tracks):

Each file is made with a different profile (dvhe.04.06, dvhe.05.06, dvhe.07.06) and all of them are organized in a single Dolby Vision layer (BL + EL + RPU).

The Terminator intro isn't the best way to test this kind of thing, but you can't have it all from life.

As always, let me know!

Re: Dolby Vision now possible through MP4 Mux.

Ok - I am on cloud 9. I just tried:

1) Game of thrones S8 UHD rip using MakeMKV
2) Extract .thd and convert to .thd+ac3 using eac3to
3) Using tsMuxeR nightly build, imported the two video layers from the mkv created in 1) alongside thd+ac3 created in 2).

It works beautifully on the X700! :-)
- Plays in Dolby Vision (confirmed by pressing info on X700 remote)
- Plays Dolby Atmos. My Denon AVR reports the stream as “Dolby Atmos - TrueHD” and the bitrate is normal (regardless of what mediainfo says).
- Lip sync is perfect! I had a hope this would happen because as I said before - lip sync is perfect whenever playing discs on the X700. It is only LPCM I see the issues.

This is phenomenal. No compromise compared to watching the disc, but with the benefit of it being totally silent from my SSD. Also, far less disc thrashing when creating the files due to no more need for the intermediate MP4.

Within 24 hours I’ve gone from regretting buying the X700 just to play DV files (due to lipsync with LPCM) to witnessing the dawn of (dare I say) an effectively no compromise situation with respect to DV remuxes. And the X700 becoming an invaluable piece of equipment. Wow.
