[SOLVED] Sony UBP-X800m2 - playing lossless Atmos from files (USB)

[anibal]

Have you tried using MKV-ToolNIX-GUI to mux your m4a/mlp/mp4 into an mkv?

Not yet, I was using MakeMKV to get an mkv file from the Blu-Ray.

 

[anibal]

For muxing content into a 'transport' [.ts or .m2ts] container, I recommend you use one of the newer 'open source' builds of TSmuxer GUI.

Also, for anybody muxing Dolby TrueHD audio into the .m2ts container you will need to include a mandatory (lossy) Dolby Digital core.

You nailed it! I just did not see it.

The problem was different for each case:
- For my own Atmos encoded sample, the AC3 core is not generated at all. I have to investigate how to do it.
- For the Blu-Ray sample, I was using an MKV as an intermediate step. The AC3 core is stored as a different track when using the MKV container and it is not recombined when remuxing into m2ts.

So, for my original question, this is solved: The Sony UBP-x800m2 can play Atmos from a USB drive as long as it is stored in a .m2ts container and the TrueHD track includes an AC3 core.

I will get some mp4 Atmos files from Immersive Audio Album and see what is in there and if I can generate and mux an AC3 core there if they do not have it.

I have both the Sony 800M2 and the Zidoo Z9X. The Z9X is my main go-to for local file (movie and immersive music, mostly via MKVs) playback, but there is one format the Z9X fails at....embedded FLAC Auro-3D playback. So I use the USB input on my Sony for that (and for all movie BD disc playback, of course). However, as per above, the Sony will not play Atmos MKVs (no big deal for me cuz the Z9X does) so I occasionally play Atmos via .m2ts files.

There are new Zidoo media players coming out very soon that would help in this regard although gapless multichannel FLAC still appears to elude the developers. Z9X Pro would be best bang for buck. https://www.zidoo.tv/Product/allProduct.html#Media Player

What's the current situation with gapless play of MCH/Atmos with Z9X Pro? Has it improved meanwhile?

No idea I'm afraid. I only have the previous Z9X and from the Zidoo forum posts on the Z9X Pro, it's a bugfest so I'd avoid purchasing one and try one of these: Dune HD Real Vision 4K Plus Sold out at the moment unfortunately but you may be able to pick one up elsewhere. I emailed Dune about it a while ago and it allegedly plays 4.0 and 5.1 FLACs gaplessly.

There is also a new model coming, Dune HD Pro One 8K Plus, based on a new Amlogic chip which now also supports pass-through not only for DTHD/Atmos but also DTS-HD/X.

Cool.

Lots of RAM so hopefully it'll get around any of the occasional Dolby Vision freezes on the Zidoo Z9X.

Be interesting to see a Dolby Vision Full Enhancement Layer too as I've never seen one and very few if any other media players can use the FEL. Dolby Vision MKV's sure have a load of extra metadata that takes up a ton of space so be good to see if DV is actually worth it.

I've added myself to the notification list so once all the early adopters have confirmed it behaves itself, I might cough up.

Thanks for posting.

Hi there!
I recently scored an Atmos-capable receiver and I am hoping to buy some lossless Atmos files from "Immersive Audio Album". However, I haven't found a way of playing any file type in my Sony UBP-X800m2 that results in Atmos playback. If I use the MKV container, the player recognizes the audio track as MLP and is played as 7.1 PCM. I can play lossy Atmos in mp4 containers. A TrueHD track in a mp4 container is not recognized at all in the player.

@harync reported in this post that he(she?they?) is capable of doing this using .m2ts container. I haven't succeeded with this, maybe is not supported any more in the latest updates? I tried creating a .m2ts file with Dolby Atmos Encoder and also transcoding an MKV to this and I get not sound at all.

BTW, I can successfully play a Blu-Ray with a TrueHD Atmos track.

I also have a Google TV Chromecast but I understand that I can not use it for lossless Atmos.

Any ideas?

Thanks!!!!

EDIT:

The Sony UBP-x800m2 can play Atmos from a USB drive as long as it is stored in a .m2ts container and the TrueHD track includes an AC3 core.
IMPORTANT: the AC3 core must be on the same track (thd+ac3).
If you only have the TrueHD track, you can generate a thd+ac3 track using eac3to, like this:

eac3to  input_file.mp4 output_file.thd+ac3 -640

Thanks for the information

Can you give step by step the process software and more about how you get the necessary m2ts file from the mkv with TrueHD lossless?

Sure,

You may download eac3to here: https://www.videohelp.com/software/eac3to
You will also need tsMuxer: https://www.videohelp.com/software/tsMuxeR

If you are using MKVs from Immersive Audio Album, for each file:

- Extract the TrueHD stream and create the TrueHD+AC3 stream, from a command line interpreter (Windows only):

eac3to  filename.mkv filename.thd+ac3 -640

- Execute the tsMuxerGUI, add both the .mkv and the .thd+ac3 files
- On the "Tracks" section, de-select the original TrueHD stream, leaving only the video and the new TrueHD Atmos + AC3 stream
- In the "Output" section, select "M2TS" muxing and the desired output name.
- Click on "Start Muxing" and that is it

Enjoy!

Thanks Annibal i give it a try

Does M2ts remains the chapter list with this method?

 

[HomerJAU]

Does M2ts remains the chapter list with this method?

No.

 

[SeeMoreDigital]

Does M2ts remains the chapter list with this method?

m2ts is a transport stream container. Typically it's capable of storing the following: -
Video: MPEG-1, MPEG-2, VC-1, MPEG-4 AVC and MPEG-H HEVC.
Audio: Dolby Digital, Dolby Digital Plus & Dolby Digital True-HD (with or without Atmos). DTS, DTS-HD HR, DTS-HD MA, DTS:X. AAC LC & HE. LPCM.
Subtitles: PGS (.sup).

As HomerJAU has already mentioned, it does not support the inclusion of chapter navigation information.

 

[Peeties]

I read on the internet

https://cloudinary.com/glossary/m2t...2TS files support,video quality and file size.

• Chapter Support – M2TS files support chapter markers, allowing for easy navigation and quick access to specific scenes or segments within a video.

So I am now studying to find a way with Eac3to to extract the playlist or chapter information from the original mkv and then try with a remux program add this information to the m2ts file; maybe someone has do this already

 

[HomerJAU]

The internet is never wrong!

You should try muxing the thd+ac3 stream into a MKV with chapters. That MKV may play in your BD player.

Edit:
Create the combined THD and ac3 stream with eacto3
Use MKVtoolnix to add the new stream to your original MKV file and remove the original THD stream (all in one process)

 

[Peeties]

This thread is dedicated to the Sony player to play steams with Dolby Atmos, and the topic starter finds a way but only with an m2ts file, not with an mkv file

To repeat... The .m2ts container does not natively support chapter navigation!

@Peeties , actually M2TS and TS containers don't support "embedded" chapters. They use .mpls files (playlists) that are present in the Blu-ray folder structures. Moreover, I have not found a way of making chapters work on the UBP-X800m2, not even with MKVs. Of course, this may be just lack of knowledge from my side. The closest way I found is keeping each album track in a different file, but that messes with gapless playback and brings some other quirks.

 

[Peeties]

Like i said i will study are on holiday plenty of time, if i find a solution i will post for sure

 

[Peeties]

I found no solution

But when i use the display button i have an idea at witch time the file is playing and i can with the forward button goes to the needed place, now a system that i can store a playlist accessible with a timetable

 

[Peeties]

And hopefully Apple announces coming monday passthrough over HDMI with Dolby Atmos over more than 8 channels
