Hi, Thank you for the new method to add lossless audio.

I'm using a Sony x700 with an OLED TV and so far, only the file with 7.1 lpcm works. When I make a DV mp4 with DTS-X, DTS-HD or even DTS, it plays in DV without sound. It doesn't even say '' audio not supported'', just like there isn't any audio in the file.

btw, I watched two complete movies in Dual layer with lossless 7.1 lpcm without any issue. this is really awesome.

Hey guys,
I found an interesting paper on including TrueHD (MLP) bitstreams into ISO base media file format(mp4) - https://developer.dolby.com/globalasset ... format.pdf - I already contacted Dolby regarding a sample implementation :)
Interesting. I had already tried it but I can't find a valid Meridian audio encoder.

Hi guys
Here's an example of how to remux a dv movie composed with multiple m2ts file with the yusesope method.

exemple with Alita Battle Angel.
1/ launch BDinfo to see what files compose the movie
Image

2/ with MPCBE see the differents M2TS
If you look 803.MPLS and play the first 00006.M2TS file, you will see that the introducing text is in french. So, 803.MPLS is the playlist for the movie in french.
Now if you look at the "AUDio" list, you can note that the french DTS track is numbered 1104.

Image

3/ now we need to find the corresponding "map" number for the audio track we want to demux

Code: Select all

ffprobe -i F:\BDMV\STREAM\00006.m2ts
Image

1104 => map number 0:7

4/ create a "m2ts_list.txt" file, and list inside the differents .m2ts files

Code: Select all

file 'F:\BDMV\STREAM\00006.m2ts'
file 'F:\BDMV\STREAM\00688.m2ts'
file 'F:\BDMV\STREAM\00021.m2ts'
file 'F:\BDMV\STREAM\00689.m2ts'
5/ now here's the magical command to demux the list of the m2ts as BL and EL hevc files and audio.mp4 (containing the french dts track)

Code: Select all

ffmpeg -f concat -safe 0 -i m2ts_list.txt -map 0:0 -c copy BL.hevc -map 0:1 -c copy EL.hevc -map 0:7 -c copy audio.mp4
6/ assemble the DV .mp4 file

Code: Select all

mp4muxer_64bits.exe --dv-profile 7 --input-file BL.hevc --input-file EL.hevc --output-file mp4_dv.mp4
7/ add the audio to the DV .mp4 file

Code: Select all

mp4box.exe -add mp4_dv.mp4:rate=0 -add audio.mp4#audio:lang=fr-FR -no-iod mp4_dv_movie.mp4
8/ Et voila !

Code: Select all

According to the instructions in the manual, it should not even recognize an mp4 with LPCM audio.
Well, the x700 supports the following audio format/combination(the one I tried):

works
MKV: AC3, AAC,DTS, DTS-HD, DTS-x
M2TS/TS: AC3, AAC, DTS, DTS-HD, DTS-X, TrueHD Atmos, e-ac3
MP4: AAC, AC3, LPCM

player says unsupported format:
MKV: EAC3, TrueHD Atmos(because mkv split the core from the truehd)

player says nothing(like if there is no audio at all):
MP4: DTS family

all cinavia free via USB.

btw, I watched two complete movies in Dual layer with lossless 7.1 lpcm without any issue. this is really awesome.

just to clarify, and remind myself, dual layer mp4s show dolby vision on both the tv and the player? and m2ts / mkv is only hdr10?

Hi
yes, all the mp4 trigger DV and play fine with 7.1 lpcm on the TV and x700 player.
my setup is:
Sony X700 -----> Denon X3200W ------> LG OLED C8

m2ts and mkv only play in HDR because there's nothing yet to author DV in these containers. I think the best solution would be in a .TS container since that supports all the lossless audio and DV single layer(I would guess dual-layer too).

yeah exactly, that's why I've already asked DVDFab to change from mp4 to ts container weeks ago, but they never responded :roll:

whoa cool, my new TV arrives Friday so I'm in between testing right now. I've read that the new emby beta app for it will do single layer dvhe.05.06 with 7.1 pcm audio as it's based on exoplayer2. I'm not sure if you've made any single layer mp4s with dvdfab yet and put lpcm into them, but if so it would definitely be cool to try out.. I feel like you could probably then just set kodi's external player in the xml to emby/exo and get DV working in that even! here's a quick discussion with a link to the beta if any of that sounds enticing: https://emby.media/community/index.php? ... -4k/page-1

Is Dvdfab single layer or dual layers and is there quality difference in between the two and profiles e.g 5 ,7 etc

it has an option for both, and if you choose copy-video there's no perceivable quality difference.

The problem that I'll have that I foolishly didn't think of is this: yes I have the stick and the C9, but I don't have a receiver that will pass through DV, only hdr10. So I have the stick attached to the TV. The tv does support eARC but my receiver doesn't. This doesn't affect me currently because I don't get lossless audio through the stick. I can get DD+/Atmos (lossy) with it via regular ARC. But even if my AVR did support eARC, the C9 for some reason currently will only passthrough PCM as stereo. It's an issue that is known of and complained about on forums as apparently the new Sony handles it fine. So in summary, I guess I would only be able to test for DV, but not audio. I haven't been motivated enough to try this yet due to my setup. If DV becomes fully playable via windows 10 htpc with lossless audio, I'll be very tempted to get a new AVR.

no, I have only the appleTV 4K but I don't think it supports dual-layer mp4 and I don't have dvdfab for the single-layer mp4.

great!! if someone can figure it out, it's them. I hope they are working on it.
