pure MLP/TrueHD Codec

Hi, please download this fork of tsMuxer to test the addition of pure MLP/TrueHD Codec (needs a github account):

Win64 (https://github.com/jcdr428/tsMuxer/suites/4993766373/artifacts/146219352)
Win32 (https://github.com/jcdr428/tsMuxer/suites/4993766384/artifacts/146218936)
Linux (https://github.com/jcdr428/tsMuxer/suites/4993766372/artifacts/146218594)
Mac (https://github.com/jcdr428/tsMuxer/suites/4993766375/artifacts/146218716)

Use it with the usual tsMuxerGUI.
You can report issues here, I will not push until confident there is no side effect.

Did a quick test
tsMuxerGUI warned about a non standard BD codec but muxed it fine.
Plays back fine if the m2ts is played, however, is I tried to play back the BD structure no sound came thru.
Used BDEdit to check the playlist and none of the entries showed up (Dolby lossless, 48khz, multi-channel,etc)
I added these values and the sound works fine when played back as a BD in a software player.

Will this work with EAC3 as well?

Thanks, useful. So I'll put the same values as ac3+thd in the mpls/clpi.

Will this work with EAC3 as well?
Yes, once the trueHD job is complete I'll start working on it.

The m2ts with pure True-HD seems to be read by most software players, but the Blu-ray chips expect a compliant ac3+thd.

Agreed.
The warning about non-compliant codec should make users realize that the playback method matters

But it is a great feature for software based playback

Interesting....

My OPPO's 'front display' detects the audio stream as being 'TrueHD'. But it's 'on-screen' display (as seen on the TV) does not register any audio format being present.

Also, after a few seconds the file stops playing and the OPPO crashes :(

The hardware requires compliant streams, I guess.
For software or media player playback it is a good feature

Such as adding a blank 32kbps 2-channel AC3 frame before each TrueHD frame. This would allow the Blu-ray players to read the TrueHD, but it would be strange to have an empty AC3 stream in the m2ts.

As per the Github entry, that should work for hardware players (compatibility wise).
I would guess that modern equipment all support the HD versions of audio

It would re-introduce spec compliancy and so get rid of playback method issues.

It would also be a good solution to eac3 without a core.

Don't need to be a empty stream, can be a downstereo recode with:

eac3to input.thd output.thd+ac3 -downStereo -32

The output is:
TrueHD/AC3, 7.1 channels, 48kHz
(embedded: AC3, 2.0 channels, 32kbps, 48kHz)

Indeed that would be much better to transcode the AC3 with eac3to rather than adding a silent AC3 stream.

It would also be a good solution to eac3 without a core.

I believe that pure eac3 are already accepted by tsMuxer ?

I just tried the latest nightly and tsMuxeR threw an error.
Pure eac3 is not a compatible codec, aborting
Deleted the playlist fom the structure it created

I am referring to the BD folder selection

I think I would prefer an empty core like the Atmos E-AC3 streaming services use. It works perfectly fine on my bluray player

It would be a very nice option - if plain TrueHD is detected, add an option to generate THD+AC3 with empty core all within tsMuxer.

Oh, yeah, I know and use that already.

What I'm saying is it would be more convenient to have this within tsMuxer.

For me, eac3to takes quite some time to transcode TrueHD to AC3 for core. I assume it'd be faster to have tsMuxer generate empty frames.

In my case, I'm playing my media on an Oppo clone which passes audio to my AVR which supports TrueHD. So I'm ok with an empty core. Other users might have different use cases.

Kuler087

26th January 2022, 18:33

@shroomM exactly!

plus I don't see the point of encoding a 32kbps 2.0 core, might as well encode it at 640kbps 5.1 instead.

...plus I don't see the point of encoding a 32kbps 2.0 core, might as well encode it at 640kbps 5.1 instead.
While this would be preferable, it would however require the addition of an audio 'encoder' to generate the Dolby Digital core!

On the plus side (if I understand correctly), it sounds like it might be possible to create an 'Blu-ray spec compliant' empty/fake (32kbps 2-channel) core using TSmuxer alone ;)

Kuler087

26th January 2022, 19:06

empty/fake (32kbps 2-channel) core using TSmuxer alone ;)

How do you make thd+ac3 with a fake 32kbps core without re-encoding?
Last time I checked, encoding at 640 or 32kbps in eac3to takes the same time.

So if making an empty core is possible right now, i'd like to know how because I'm wasting a LOT of time re-encoding a 640 ac3 to my trueHD track from mkv files.

There would be no encoding involved -only interleaving the same 128-byte silent/blank AC3 frame before the TrueHD frames.

dual track dual layer TS/m2ts files have a nasty bug on the oppo and sony x700. You can't play two files in a row otherwise the player is locked with a green-purple screen.

https://forum.doom9.org/showthread.php?p=1931032#post1931032

I would keep both options available though because some ST-DL files won't play at all.

EDIT:. it turns out the x800m2 is not affected by this bug, it might be an x700/oppo bug after all because I read they both have the same SOC

Would it be possible to apply this solution to the no core E-AC3 tracks in order to create a "core" and make it compliant?

Edit: IMO it cannot be done with eac3 streams: in Blu-rays the eac3 frames are coded to be a complement of the ac3 core. The only way to change eac3 to ac3+eac3 is to reencode.
Whilst TrueHD frames are totally independent from the ac3 frames: the frames are simply interleaved in the same stream.

In case of importing TrueHD+Atmos or EAC3 JOC, it would be nice if tsMuxer GUI's track info would show such information.
Any chance this can be implemented?

Wow, that's quick, thanks. Can you do this for E-AC3 JOC too?

Wow, that's quick, thanks. Can you do this for E-AC3 JOC too?

@von Suppé True-HD was easy: if there are four substreams, the fourth is deemed to be Atmos.
It is more complicated for EAC3 JOC: from what I can gather all audio frame and blocks need to be fully parsed before arriving to the auxiliary data, so as to test the presence of Atmos metadata.
