Thanks for the update!
I did a test using the "Amaze ATMOS" demo and compiling FFmpeg from the Git repository (master branch).
The following command allows you to mux the ATMOS track inside the mp4 container
Code: Select all
ffmpeg.exe -i amaze.mkv -c copy -strict -2 amaze.mp4
There seems to be some issue with the output (take a look at the mediainfo).
I could not play the audio of the file (neither on the PC using the latest LAV Filters nor on the TV).

MP4Box recognizes the mlpa track and allows the mux inside the mp4 container but, as I said before, I can't play audio.

I'm getting the same result
... I'm still going to try it on the oled tonight...
EDIT:, nop, no go in the TV(which supports atmos and dts=x). no audio detected....
But it's still a step in the right direction. FFmpeg dev should be able to fix that.

So I've compiled ffmpeg from git.
I now saved the truehd audio track from Alita to a new mp4 container.
Code: Select all
Input #0, mpegts, from 'bluray:./':
Duration: 00:03:28.21, start: 11.646667, bitrate: 2251891 kb/s
Program 1
Stream #0:0[0x1011]: Video: hevc (Main 10) (HDMV / 0x564D4448), yuv420p10le(tv, bt2020nc/bt2020/smpte2084), 3840x2160 [SAR 1:1 DAR 16:9], 23.98 fps, 23.98 tbr, 90k tbn, 23.98 tbc
Stream #0:1[0x1015]: Video: hevc (Main 10) (HDMV / 0x564D4448), yuv420p10le(tv, bt2020nc/bt2020/smpte2084), 1920x1080 [SAR 1:1 DAR 16:9], 23.98 fps, 23.98 tbr, 90k tbn, 23.98 tbc
Stream #0:2[0x1100]: Audio: truehd (AC-3 / 0x332D4341), 48000 Hz, 7.1, s32 (24 bit)
Stream #0:3[0x1100]: Audio: ac3 (AC-3 / 0x332D4341), 48000 Hz, 5.1(side), fltp, 640 kb/s
....
It's the truehd one at 0:2.
So by simply doing:
Code: Select all
ffmpeg -i bluray:./ -map 0:2 -c copy -strict -2 ../alita_demux/truehd.mp4
It will mux the truehd track into a "new" container:
Code: Select all
Output #0, mp4, to '../alita_demux/truehd.mp4':
Metadata:
encoder : Lavf58.31.104
Stream #0:0: Audio: truehd (mlpa / 0x61706C6D), 48000 Hz, 7.1, s32 (24 bit)
Stream mapping:
Stream #0:2 -> #0:0 (copy)

So now what?
I now use MP4Box to mux the truehd stream from the truehd.mp4 container into my DV mp4 container which I've created with dolby mp4muxer?

Well I tried to add the truehd track with MP4Box.
So for the record:
alita.dv.mp4 - The DV movie created with Dolby's mp4muxer (from the base-layer and enhanced-layer), only contains the two video layers
truehd.mp4 - The TrueHD audio track muxed into a mp4 container with ffmpeg:
ffmpeg -i bluray:./ -map 0:2 -c copy -strict -2 truehd.mp4
dolby.ac3 - The Dolby Digital 5.1 audio track saved with ffmpeg:
ffmpeg -i bluray:./ -map 0:3 -c copy dolby.ac3
Code: Select all
MP4Box -add alita.dv.mp4:rate=0 -add truehd.mp4#audio:lang=en-US -add dolby.ac3#audio:lang=en-US -no-iod Alita.Battle.Angel.2019.DV.TrueHD.AC3.mp4

As it reports the truehd (mlpa) track as 2-channels instead of 7.1
EDIT:
Here's the information regarding the truehd.mp4 container which contains the truehd track:
Code: Select all
General
Complete name : truehd.mp4
Format : MPEG-4
Format profile : Base Media
Codec ID : isom (isom/iso2/mp41)
File size : 4.33 GiB

So it looks like FFMpeg still needs some work as the codec ID should be: A_TRUEHD and it sohuld at least report 7.1 channels...

What linux you use? maybe you can help me compile dlb_mp4base
I use 4.19.66-1-MANJARO x86_64 GNU/Linux and my error:

Did you run the "make" command inside the appropriate directory?

A_TRUEHD is a codec tag used for the matroska container. I think the MPLA id is the right one. I don't know if out there there is a player that can start playing an audio track with this codec descriptor: if a device (like ours TVs) is unable to do so, it will need a firmware update (don't worry...it won't happen).
It seems to me that we're stuck at the same point...

I used DVDFab's UHD Copy to burn a movie file onto a blank Blu-ray disc yesterday and, as it turns out, it keeps the Dolby Vision AND the lossless Dolby Atmos track. I downloaded Rocketman (found an HEVC upload of it, which is the entire disc including Dolby Vision), and after burning a copy onto the blank disc, I played it on my Sony UBP-X700 Blu-ray player. Sure enough, this popped up. I have yet to test a rip of one of my 4K Blu-rays, but I'm sure it'll work roughly the same.

Just a lurker here just paying attention to see if this ever really works fully. Sorry to ask a quick hijacking question but I wonder if it might be answered by what is necessary in the efforts of those trying to figure this out: Is it possible with freeware (or cheapware) to convert lpcm (actually flac) to Dolby true HD losslessly? Obviously wouldn't have Atmos metadata. Thanks.

I do the same when a movie fit a BD-50 but almost all the movies are larger than that(even without all the audio and menu) and triple-layer BD-R are very expensive. yes, you can encode it to fit a BD-50 or even a BD-25 but it's not an option when you only want to watch the best quality possible.

Freeware, no. Dolby TrueHD is proprietary, and there is no current free alternative to buying a license from Dolby.
