Looking for a eac3 7.1 encoder

thanks but I already wrote my own script that converts UHD-BD to profile 8 DV with EC3 7.1. So @tebasuna51 manual solution works well, I just tried.

%ffmpeg_path% -drc_scale 0 -i %input_path% -map 0:%ID% -filter_complex "pan=7.1|c0=c0|c1=c1|c2=c2|c3=c3|c4=c6|c5=c7|c6=c4|c7=c5" -rf64 auto -c pcm_s24le %TEMP%temp.wav

EDIT:

This whole story got me curious and I checked an original BD with a 7.1 EC3 track and the channels are also out of order.. seriously Dolby wtf?

Your EAC3 has DRC applied... are we sure there is no any metadata in EAC3?

I imagine this is why most Blu-rays have no EAC3. And of course EAC3 having AC3 inside.

Yesterday Audacity Stable was released, BTW with support of HEAD of ffmpeg.

I dont know how to check if a file has DRC.
check your PM I sent you a link to the whole 7.1 EC3 Atmos track from the Justice League BD.

FL FR FC LF BL BR SL SR
and ALL eac3 7.1 encoders are wrong and ignore that order
(only EAE based in ffmpeg know that),
even if the wav file have the correct channelmask, and read it like:
L R C LFE Ls Rs Rls Rrs
(Ls=SL, Rrs=BR)

conclusion: friends don't let friends use 7.1 "enhanced"-AC-3. :-|

First of all what is this:
L R C LFE Ls Rs Tfl Tfr

Never saw it on blu-ray, nor did I ever see Bit rate: 1 512 kb/s for eac3.
Duration: 4 h 2 min on Blu-ray was also a shock, but yeah, long movie... There is no EAC3 sound on Blu-ray... There is AC3 core on your sample in my DM. So that at leasy checks out (00001F47 strmtyp: 1 (0x1) - (2 bits)):

Type 1: These frames comprise a dependent substream. The programme shall be decoded in conjunction with the independent substream with which it is associated.

Are you referring to EAC3 being present on a particular Blu-ray disc or EAC3 (without an AC3 core) being available on the Blu-ray format in general? If it's the latter then you are wrong...

The same than (L R C LFE Ls Rs Vhl Vhr) a EAC3 channel map than can be obtained with Audition 2017.

And is played in my AVR like it was a Atmos 3D 5.1.2 front

Of course aren't in BD's but if Atmos tracks are recoded to (L R C LFE Ls Rs Vhl Vhr) can save space and sended by SPDIF (my TV SAMSUNG player to AVR-DENON). It is my only interest in eac3 8 channels, for me 2D 5.1 and 7.1 are the same.

The track come from this bluray:

The first, but apparently there is such a Blu-ray.

BTW, "C:\tmp\Plex\Plex Media Server\Plex Transcoder.exe" -c:a pcm_s24le -i "C:\Users\Pepe\Core.wav" -eae_root C:\Users\Pepe core.eac3

This command uses -c:a pcm_s24le, but it is not needed here, wav encoding defaults to 24 bit to flac, eac3, truehd (with newer ffmpeg with activated 24 bit TrueHD that is). No, the only time it is needed is if you decode .thd to wav or .eac3 to wav. BTW, I still think drc_scale and normal native ffmpeg should be used to decode.

Waiting for proper support in deew of Atmos, is there a way to have 5.1.2 instead of 7.1?

I understand that Vhl is Tfl. And Vhr is Tfr. The problem is I never saw something like that on Blu-ray. And I never saw such high bitrate. Again, this is native Blu-ray. This cannot be Audition 2017, because the eac3 sample is JOC, i.e. Atmos.

Like I say in the Deew thread I don't know how pass the correct channel map (5.1.2) to Dolby Encoder Engine, and dee.exe ignore the channel mask of wav file input and output always 7.1

Well, Netflix somehow encodes Artmos into 5.1 EAC3. Even 16 objects.

[Balling]

BTW. Be careful with leaked Dolby media encoder. It does not produce lossless TrueHD with stereo wav (it is mostly lossless though, I tried Plex decoder of TrueHD and ffmpeg's), did not check what happens with leaked Encoding Engine.

[Balling]

BTW, you can turn off "DRC default on" and plex will not do DRC.

Also, it is not safe to discuss wärexxx on this board :-|

If you want to encode 71sh/512sh, DTSHR supports it in DTSMAS & Mainconcept Totalcode, but you may need to play with NeuralX & Speaker setup settings.
