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.mp4I could not play the audio of the file (neither on the PC using the latest LAV Filters nor on the TV).

Re: Dolby Vision now possible through MP4 Mux.
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.

Re: Dolby Vision now possible through MP4 Mux.
So I've compiled ffmpeg from git.
I now saved the truehd audio track from Alita to a new mp4 container.
It's the truehd one at 0:2.
So by simply doing:
It will mux the truehd track into a "new" container:
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?

Re: Dolby Vision now possible through MP4 Mux.
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
I think MP4Box somehow messed up:
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:
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...

Yep I tried git clone again now it is ok, thx.
Re: Dolby Vision now possible through MP4 Mux.
You're welcome!
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...

Re: Dolby Vision now possible through MP4 Mux.
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.

Re: Dolby Vision now possible through MP4 Mux.
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.

Re: Dolby Vision now possible through MP4 Mux.
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.mercwithamouth wrote: ↑Thu Aug 29, 2019 9:02 pmI 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.
