Dolby Vision

Test_DV_LPCM
Dolby Vision + LPCM (24bit big-endian)
Dolby Vision + FLAC

All play, but no sound

Have you tried using an Apple TV 4K or a TV (via USB, via NAS / DLNA, etc ...)?
I'm not aware of any TVs able to decode PCM or FLAC audio by itself (so it would be normal to have only the video playing).
In this case, you should test the "Dual Layer" file.

Also tried to created own single-layer video with dvdfab, but it kills my TV: black screen after start and then TV turn off and don't turn on until plug it out/in from socket.

I'm sorry to hear that. You should write something about it on their forum.


EDIT:
I realized now that you have edited your post: try the "Dual Layer".

TV. Don't know any app on AppleTV that can play users DV.

Are you using dvdfab too? Maybe I messed up with settings.

My TV can't play Dual Layer, only single one

It would seem that mrmc is able to do this (read the previous page and
take what is written with a grain of salt).
And you're also writing on their forum. What a coincidence!
I suggest you buy the PRO version and support their work.
You should listen to someone (like me) who doesn't even own an Apple TV.


@ davilla
I want to talk to the marketing department ... I want a raise!

Are you using dvdfab too? Maybe I messed up with settings.

Yep...but after I edit the file (read the last few pages).
I seem to have understood that my files have not caused problems to your TV. right?

Last update was in april. No DV in this version. Actually for now there is no apps on AppleTV that support DV.

What? Where?

Right, that's why I'am asking about settings. There is no single movie on internet that uses single layer DV (netflix, itunes, amazon, etc doesn't count).

Test_DL_DV_DTS_HD_MA.mp4 plays, can't say anything about the 2nd video stream as MrMC only handles one right now.

My bad! I should have read the previous posts! Sorry!
It is worth testing anyway (I appeal to the owners of LG, Vizio, Sony, etc...)

I don't get why you want to bother with dual layer dv? There are only 4 DV TV's that can do e-arc: the LG C9 and a few Sony's. Vizio, TCL, Hisense, etc, won't pass hd-audio to your receiver, so you'll only get lossy audio anyway- it would be no better than using dolbymp4muxer with eac3 audio.

If you shift your focus to primarily single layer with hd-audio, then external devices other than just uhd-bd players can be used as they have hdmi going right to your AVR. things like ATV 4k, Fire TV 4k, and possibly even kodi on newer dv-supporting android boxes could work! Would you be able to take an actual lossless single layer dv mp4 from dvdfab, do your magic to give it lossless atmos/dts:x, and upload a clip to test? I'd like to see what all can support it, especially MrMC obviously.

Sorry but wrong, DV (single layer) handling came in years ago.

And big endian is a winner

Test_DV_LPMC_BigEnd.mp4 plays and shows 8 audio channels
Test_DV_FLAC.mp4 plays and shows 8 audio channels.

1st confirmation by others that DV works in MrMC. Note the testflight version.
https://forum.mrmc.tv/viewtopic.php?f=3 ... =30#p11458

It works, others have tested. I wrote the code and understand it pretty well.
All you have show here is that DV does not play under your setup. Debuglog and we can figure out why. Otherwise, not much can be done to resolve YOUR issue.

############### TOOLS ###############

DVDFab (11.0.3.9 or newer) (HERE)
FFmpeg (HERE)
mp4muxer (HERE)
mp4box (from GPAC SDK) (HERE)

GPAC.exe can be unzipped using 7zip: binary files are located in the "bin" folder.


######### "DUAL LAYER" DOLBY VISION: THEORY #########

Use FFmpeg to demux the video Base layer (BL), the video Enhancement layer (EL) and the audio stream. The audio stream will be also copied/encoded and stored in the right container (see APPENDIX A).
For testing purpose, I suggest you work on 60 seconds cuts. See APPENDIX B.

Use mp4muxer to mux BL and EL (without audio).

Use mp4box to mux the "Dual Layer" .mp4 file (generated by mp4muxer) and the audio stream (generated by FFmpeg).


# "DUAL LAYER" DOLBY VISION: REAL CASE SCENARIO (example with ATMOS) #
Make your choice:

• #EXPERIMENTAL# if your setup can handle tracks with TrueHD/ATMOS encoding

  Code: Select all

  ffmpeg.exe -i bluray:\path\to\bluray -map 0:0 -c copy %userprofile%\Desktop\BL.hevc -map 0:1 -c copy %userprofile%\Desktop\EL.hevc -map 0:2 -c:a copy -strict -2 %userprofile%\Desktop\atmos.mp4

• otherwise, if your setup does not handle tracks with TrueHD/ATMOS encoding (or the previous method does not work for you)

  Code: Select all

  ffmpeg.exe -i bluray:\path\to\bluray -map 0:0 -c copy %userprofile%\Desktop\BL.hevc -map 0:1 -c copy %userprofile%\Desktop\EL.hevc -map 0:2 -c:a pcm_s24be -ar 48000 -rf64 auto %userprofile%\Desktop\lpcm.mov

• Enter the appropriate file (atmos.mp4 or lpcm.mov) in the last command line based on the choice made previously.

• Note the syntax --> -add stream[:opt1:...:optN]

######### "SINGLE LAYER" DOLBY VISION: THEORY #########

Use DVDFab to generate a "Sigle Layer" .mp4 file (choose the "single layer" profile, deselect any optimization settings and export the file without any audio track)

Use FFmpeg to demux the audio stream. The audio stream will be also copied/encoded and stored in the right container (see APPENDIX A).

Use mp4box to mux the "Single Layer" .mp4 file (generated by DVDFab) and the audio stream (generated by FFmpeg).


# "SINGLE LAYER" DOLBY VISION: REAL CASE SCENARIO (example with ATMOS) #

Code: Select all

Use DVDFab as indicated above and generate an .mp4 file (dvdfab_out.mp4)

Make your choice:

• #EXPERIMENTAL# if your setup can handle tracks with TrueHD/ATMOS encoding

  Code: Select all

  ffmpeg.exe -i bluray:\path\to\bluray -map 0:2 -c:a copy -strict -2 %userprofile%\Desktop\atmos.mp4

• otherwise, if your setup does not handle tracks with TrueHD/ATMOS encoding (or the previous method does not work for you)

  Code: Select all

  ffmpeg.exe -i bluray:\path\to\bluray -map 0:2 -c:a pcm_s24be -ar 48000 -rf64 auto %userprofile%\Desktop\lpcm.mov

mp4box.exe -add %userprofile%\Desktop\dvdfab_out.mp4 -add %userprofile%\Desktop\atmos.mp4 -brand mp42isom -ab dby1 %userprofile%\Desktop\mp4box_out.mp4

• Enter the appropriate file (atmos.mp4 or lpcm.mov) in the last command line based on the choice made previously.
