Unfortunately the fact that MMH doesn't provide execution output makes it hard to understand what is going wrong...

Is there a verbose mode of MMH (when performing a command line start)? I don't think so. So, yes, you can't what happens.

Is there any skin where channel definitions (L, R, SL, SR, etc.) are not in light blue on slightly less light blue?

Have you tried this in MMH 9 or just 8? I don’t plan to fix anything in 8 now.

There are changes in ffmpeg major versions between 8 & 9 too.

I’ll check out the colours today.

The MMH 9 User defined dialog looks ok with the default dark skin on my PC:

Hrmmm... I will investigate further on my machine's theme or something... I have tried switching them, even trying the "High Contrast" one, in Windows 10. To no avail. Those boxes remain with a blue background. Let me know if I can do anything to further debug this.

A related, but not cosmetic question: what is the "Refresh" button supposed to do in the User Defined Remix Channel Mapping. I guessed it updated the graphic representation when manual editing was done in the "FFMPEG filter" text box but that does not appear to be the case. It... it seems to be doing nothing, tbh.

Tried both things in 9.0.0 beta 7 too. Same result.

I'm not sure if this is the correct place to ask, so sorry if not. I was wondering if anyone might know why I'm unable to convert the truehd Atmos files from the LOTR extended films to eac3 Atmos. Everytime I try, the output is only half of the length of the movie, I think it's only converting part 1 of the file. Anyway to fix this? Using the 9.0.2 beta. Using an online sourced Atmos track I was able to get the full length but there was 6 seconds of added silence between the two tracks.

 

[rogerspencer]

Hi I am new to this as well, I have been trying to do something similar but used ffmeg directly.
I do not think using the eac3 container will not preserve the Atmos metadata, it certainly didn't of me. Not sure if this is important to you

It’s not clear what you actually using.

If you don’t want lossless Atmos, then just convert the 7.1 core to 16 bit FLAC or EAC3 if it’s about saving disc space.

Sounds like you are decoding Atmos to 16ch wav then reencoding the Atmos EAC3. The issue there is the joined Atmos streams (2 discs into 1 MKV file). The Dolby reference player, used to decode, is known to reject joined or split Atmos streams.

Is it possible to have Dolby Digital Plus as an output option if using a 5.1 file not in Atmos?

Which tool? Extract Audio from MKV?

Which tool? Extract Audio from MKV?

Currently I'm looking at some flac 5.1 files but I have 5.1 files in lots of formats. I think I'm falling on DDP as the best quality for the size. Streaming my 4GB albums can take a toll... The downmix seems to sound better when I stream to my headphones, too.

What file type do you want for the output? (I'm about to release MMH 9 beta 8)

If you are using Kodi then .m4a would be my recommendation. tagging is fully supported. Easy to implement too.

 

[HomerJAU]

Whereas the following command works perfectly:

I fixed this just just now in MMH 9 beta 8 which I'll upload later today

MMH 9 uses ffmgeg 7 (7.1.1 in beta 7+). MMH 8 uses ffmpeg 6.

"hexadecagonal" is now the new "9.1.6" channel layout in ffmpeg - MMH 9 now correctly uses "9.1.6" and 'translates' hexadecagonal in a saved Channel layout to 9.1.6

Yes. m4a is perfect.

 

[DistantEarth]

Yes. m4a is perfect.

Also, I've been usin Symfonium on my Shield TV. The interface does not work well for a TV app yet but I think the dev is looking into it. It will play DDP files gapless. It's pretty great. For whatever reason, if you have Dolby Proccessing on in the Shield settings it will stutter. Turn off Dolby Proccessing and allow passthrough to the reciever and it works great. So I can use the app on my phone for headphones and car then the app on my TV for 5.1 audio. I don't have to keep two directories anymore. I just have my eac3 albums on a Jellyfin server along with my stereo albums. I hope to re-encode my flac 5.1 albums to DDP eac3. ffmpeg does pretty good but I understand the Dolby Encoder can do a slightly better job.

 

[HomerJAU]

Yes. m4a is perfect.

I can confirm this is now implemented. M4A will contain eac3 @640kbps. I've tested 5.1 FLAC to 5.1 EAC3 into .m4a (tags are copied)

MMH 9 Beta 8 will go up today.

I don't understand this? I didn't implement this using the Dolby Encoder. Its ffmpeg -> eac3.

MMH 9 Beta 8's 'Channel Remix' tool has a new 'EAC3' checkbox with the 'Remix 6Ch, Resample & Reencode' option

Prior to this change that always created FLAC files. With EAC3 checked in creates EAC3 @640kbps

Its in the Remix tool as that was easiest place to add it and that tool supports recursive sub-folder conversions (i.e. do all your folders at once)

Version 9.0.0 Beta 8 (March 16 2025) changelog since previous beta 7 a week ago

Since colors in User Defined Remix Channel Mapping are still wrong for me... is there anywhere I can modify files manually to change them?

 

[HomerJAU]

What skin are you using in MMH 9?

 

[gorman]

What skin are you using in MMH 9?

WXI Clearness, at the moment. The problem was present for every skin I have tested.

 

[HomerJAU]

Please try WXI Darkness. That’s the one in my screenshot.
