OK I got hold of your 0.0.4 beta package and did the following

• Ran MUX_EXPERIMENTAL.bat adding in the main M2TS file from the movie 1917. I updated the script within the .bat file to

  Code: Select all

  python-3.7.6.amd64\python.exe src\app.py -mode_exp 2 -skip_hdr10plus -mux_exp

• Imported the resultant HEVC file into latest version of MKVToolNix and added film title followed by 37 underscores. I added the M2TS file from 1917 into MKVToolNix excluding everything except Atmos audio and one subtitle track.

• ran MKV_Patcher.bat dropping in the MKV file created and typed 8.

Unfortunately the end result MKV file does not play at all. It freezes with black screen

No, you didn't do anything wrong!
I'm just looking for a way to save you time!
I can't directly test what I write that's why your feedback is important!
We are in a testing phase, it is normal for something not to work.

If you want a playable file, you can find the latest operating instructions HERE.

Now, I'm more than sure the experimental muxer works ...
If you feed the broken MKV file to MakeMKV (version> = 1.15.3), do you get a playable MKV?

The more practical ones could also try to use the experimental muxer by replacing the first steps of the instructions (always this POST) with it.

OK I made change to my process that works - note change made in bold:

Using 0.0.4 beta package and did the following

• Ran MUX_EXPERIMENTAL.bat adding in the main M2TS file from the movie 1917. I updated the script within the .bat file to

Code: Select all

python-3.7.6.amd64\python.exe src\app.py -mode_exp 2 -skip_hdr10plus -mux_exp

• Demuxed Atmos track from 1917 .M2TS file using TSMuxer

• Imported the resultant HEVC file into latest version of MKVToolNix and added demuxed .ac3 file generated by Tsmuxer.

• Added film title followed by 37 underscores and create MKV

• ran MKV_Patcher.bat dropping in the MKV file created and typed 8.

The resultant MKV plays in DV with Dolby Atmos track! Result. However as I have a Z9X and a LG CX TV there is a known issue. The TV keeps resyncing and after about 5 minutes playback gets choppy. Hopefully at some point this will get fixed

just a though....

it would be nice to have .BAT for the following operations (if possible)...

1) convert BL.hevc with HDR10+ to BL.hevc without HDR10+ (separately, without muxing to DV file)
2) convert EL (FEL).hevc to EL (MEL).hevc (separately, without muxing to DV file)

The first should be possible I think, the second... I really don't know...

Right now, if I want to create Profile 8.1 without HDR10+, i need to use MUX.bat with -skip_hdr10plus, then demux, and then use MUX_AND_CONVERT_TO_PROFILE_81.bat and use BL.hevc without HDR10+

For 1) above couldn't you do what I did with the FEL movie 1917? See post above.

Great result! Thanks for not giving up! It's a shame about the Z9X + LG CX problem.
So, are you telling me the only difference was the way you imported the audio into MkvToolNix?
Strange!
When someone with a FireStick 4K\Shield 2019\Ugoos tries it, maybe we'll have some more data to think about!
To you others, which of the following two approaches works?

I am glad that both the experimental muxer and the Patcher are working correctly!
The second is still not perfect: in case it returns an error, attach the first 20 seconds of the mkv to your post so I can improve it!

ok... so when I want to encode BL, i need the original EL and mux with encoded BL to have profile 8.1 again, right?

Quite right (mux in -mode 2 for profile 8.1).
However, I do not recommend video encoding: it is technically wrong in the case of DoVi and my tool is not designed for this type of use!
Just my two cents, you are free to do what you want!

All those ".bat" files are USELESS!
They just generate confusion and I certainly will not create new ones!
The only useful one is "SHOW_HELP.bat": it tells you what to use to build a simple command line.

In your specific case, is it so complicated to open a Command Prompt window in my tool folder (tutorial HERE) and paste the following command line into it?

Code: Select all

python-3.7.6.amd64\python.exe src\app.py -mode 2 -skip_hdr10plus -mux -bl \path\to\your\BL.hevc -el \path\to\your\EL_RPU.hevc  -of \path\to\your\output\file.hevc

Or even better, use the experimental muxer and save yourself the trouble of demuxing BL and EL?

Code: Select all

python-3.7.6.amd64\python.exe src\app.py -mode_exp 2 -skip_hdr10plus -mux_exp -if_exp \path\to\your\input\file.m2ts -of_exp \path\to\your\output\file.hevc

Read the two command lines aloud: it's English ... not ancient Aramaic!

I managed to get something off my local http web server but that’s not exactly ideal

You just need a simple DLNA server (the DLNA capabilities of Windows, Plex Media Server, Serviio, minidlna, etc ...)

I saw that.. with experimental muxer... with the default one, you cannot use "skip_hdr10plus" with "mode 2"

Encodes work great using profile 8.1. The only thing, you cannot CROP.

in help is written, that -skip-hdr10plus cannot be used with -mode 2... or this belongs to -fel_to_mel option before? if yes.. that my fault and wrong text formatting in CMD line.

I get a strange think after using MKV_patcher...

Have you used the Patcher more than once on the same file (or in any case on a file that was already marked as dvhe 07)?
If the answer is yes, then I suggest you delete the file and start over!
The patcher should only be used once and on a blank file (not marked as dvhe).
Follow the instructions!

Yes the only change was to demux the audio track using tsmuxer. In fact I also demuxed the audio using MKVToolnix to produce a .mka file. This I then used in place of the .ac3 file and got exactly the same result.

i have empty line break between "Enhancement Layer)" and "Cannot be used.." so it looks like it belongs to -skip-hdr10plus

Have you used the Patcher more than once on the same file (or in any case on a file that was already marked as dvhe 07)?

Yes... without the patch, file was generated as dvhe.07.00, and when run through MakeMKV, i go dvhe.07.00, EL+RPU... not BL...
After using the patch on that king of MKV, MakeMKV recons the MKV correctly and after re-re-mux, it's already OK....

My work flow:
1) mux BL+EL with -fel_to_mel
2) mux BL_EL_RPU.hevc with mkvtoolnix to MKV
3) re-mux with MakeMKV... got "Dolby Vision, Version 1.0, dvhe.07.00, EL+RPU" (MakeMKV recognized MKV from step 2 as dvhe.07.00, BL+RPU)
4) patch with mkv_patcher... got "Dolby Vision, Version 1.0, dvhe.07.06, BL+EL+RPU, Blu-ray compatible / Dolby Vision, Version 1.0, dvhe.07.00, EL+RPU"
5) re-mux with MakeMKV... got "Dolby Vision, Version 1.0, dvhe.07.06, BL+EL+RPU, Blu-ray compatible)
6) done... even MakeMKV recognizes the file from step 5 as dvhe.07.06, BL+MEL+RPU...

Stop at step 2 and use my patcher on the mkv generated by MkvToolNix and you are done ...

The resultant MKV plays in DV with Dolby Atmos track! Result. However as I have a Z9X and a LG CX TV there is a known issue. The TV keeps resyncing and after about 5 minutes playback gets choppy. Hopefully at some point this will get fixed

Great result! Thanks for not giving up! It's a shame about the Z9X + LG CX problem.
So, are you telling me the only difference was the way you imported the audio into MkvToolNix?
Strange!

Yes the only change was to demux the audio track using tsmuxer. In fact I also demuxed the audio using MKVToolnix to produce a .mka file. This I then used in place of the .ac3 file and got exactly the same result.

We will discuss it again when someone else (with a device other than yours) does some testing.
For now, thanks for your time!

ok... but why MakeMKV recognizes the file as "dvhe.07.00, BL+RPU" and creates "dvhe.07.00, EL+RPU"?

after my workflow, everything is correctly recognized in MakeMKV, ever MEL or FEL...

Don't get me wrong.. I really appreciate your great work. I'm just trying maybe help to make things easier and clearer...

And one question... are thore underscores still needed in "Movie Title" for MKV patcher?

No problem!
Do what you see fit!

I was saying it to save you time!

Why MakeMKV does not detect the correct profile level (07.00 vs 07.06) depends on the fact that my FEL -> MEL are not standard! The technical explanation can be found on the previous pages!


Yep, underscores are the heart of my hack ... without them the patcher can't work!

Sorry for the stupid question: where you put the underscores?
Example the film title is Back. Should I write Back73_ (if I choose prof.7)?
I have tried different ways with these underscores and, after the Mkv_Patcher always get this:

Where I am wrong?
By the way if I load the file from toolnix in makemkv I got DV and also hd audio and plays in Firestick and Ugoos and Shield.
But the file generated from Mkv_Patcher only plays in hdr.

In MkvToolNix, before start muxing, go to the "output" tab and in the "file title" field enter the title you want followed by 73 underscores in the case of profile 7 or 37 in the case of profile 8 (literally 73 or 37 underscores)

Code: Select all

#profile 7
Movie Title_________________________________________________________________________

#profile 8
Movie Title_____________________________________

Code: Select all

#profile 7

#profile 8

I have done it Film title followed by 73 underscores.
Still, after MKV_Patcher only get Hdr as mediainfo confirms. This is mkv_patcher. Is there any error?
