eac3to - audio conversion tool

[tebasuna51]

The eac3to normalize make impossible any clip, even if the decoder output have float values over 0dB the normalize function correct these values.

[canuckerfan]

Does anyone know the command to extract a TrueHD stream from an Atmos stream? Excuse me if it's already been mentioned in this thread, I tried searching but couldn't find it and I don't want to sift through so many pages.

[Nico8583]

A little question : is eac3to a good choice to just demux a BD (2D or 3D) ? Thank you.

[LigH]

To mainly obtain the audio streams: Yes. But it won't care much about all other streams, I believe...

[tebasuna51]

Does anyone know the command to extract a TrueHD stream from an Atmos stream?

Atmos or not you can extract the standard TrueHD (without Atmos info) with:

eac3to stream.thd+ac3 stream.thd

if the stream is already extracted, or from the BD, if TrueHD is track 3:

eac3to movie.mpls 3: stream.thd

Yes for 2D BD, I'm never try a 3D if you want recover 3D info (3D planes for 3D sups, etc.)

[Groucho2004]

To mainly obtain the audio streams: Yes. But it won't care much about all other streams, I believe...I use eac3to for de-multiplexing audio and video streams from BDs on a regular basis. I'm surely not alone.

^ OK, practical experience. :cool:

[Ripman]

I test, with eac3to, wav files with extra chunks after the data chunk without problems. For instance cue points created with GoldWave editor.

But, maybe, the eac3to behaviour can change with wav files greater than 2 GB, like here. Is know than there are soft than don't support this limit.

I can't understand how eac3to show a duration of 0:06:29 when seems (by size, channels, bitdepth and samplerate) the correct duration is 00:22:09.205 like show MediaInfo.

Thanks for your observations. Regarding the differing durations, please note the info I posted was for two different tracks in the same set (album).

I'll clean up that info for consistency, and post the wav when I get back tomorrow night. The sample is actually about 1.6gb, but I also put a 176 eac3to down sample log that shows the command line, and a pic of the static I get.

Perhaps in this case, the issue is related both to the embedded artwork and expanding to 32bit to apply gain.

[Ripman]

Thanks. I tried SoX 14.4.2 and it works just fine. Here is the sox command line I used to replicate the one I used with eac3to.

sox -V4 352.wav --rate 176400 176.wav gain -3.5 2>sox_log.txt

Just to reiterate that sox approach worked without issue.

And I'll post some additional info as described in my previous post related to a 352-176 down sample issue I had with eac3to. The hotel wifi never lets me upload something that big.

[Nico8583]

Yes for 2D BD, I'm never try a 3D if you want recover 3D info (3D planes for 3D sups, etc.)
Thank you ! BD 3D info is not a problem, I can extract it from MPLS file. I will try if MVC file extracted keeps 3D planes info.

[canuckerfan]

Atmos or not you can extract the standard TrueHD (without Atmos info) with:

eac3to stream.thd+ac3 stream.thd

if the stream is already extracted, or from the BD, if TrueHD is track 3:

eac3to movie.mpls 3: stream.thd

I'm trying something like this but I'm still getting an outputted Atmos track:

eac3to.exe "source.mkv" 2:aud2.thd

[kypec]

I'm trying something like this but I'm still getting an outputted Atmos track:

eac3to.exe "source.mkv" 2:aud2.thd

Please post your full output eac3to log.

[r0lZ]

A little question : is eac3to a good choice to just demux a BD (2D or 3D) ? Thank you.
No for the subtitles of most 3D BDs. If the same subtitles are present in the AVC M2TS and in the MVC M2TS (and it's frequent), eac3to fails completely, and you have to unselect the subtitle streams and retry. AFAIK, for everything else, eac3to works fine as a demuxer.

[canuckerfan]

Please post your full output eac3to log.

Hope this is the one.

[tebasuna51]

@junior_l3oss

When your command line don't work can be:

1) eac3to don't support this kind of eac3

2) Or the eac3 stream is buggy because:

2-1) A bad capture of video from Netflix

2-2) Or a bad stream extraction from video

We can't know the problem without a sample of your video.

[TheLastOfUs]

Seems the creator of this program 'madshi' "doesn't have the resources" for this insanely difficult problem I face....which is ridiculous.

90 google results pretty much end up in this question never getting answered. 3 times it has been asked here and never answered..but here goes yet again.

I have Nero 7 installed and I have the HD/BluRay plugin installed and registered yet EAC3TO still seems to crap on me. It keeps saying cannot find Nero Audio Decoder 2..which is BS.

TL;DR

I think program is dead when trying to do AAC to AAC/M4A

[tebasuna51]

I have Nero 7.11.10.0, and Blu-Ray/HD DVD Video Plug-in, and work in W 7 without problems:

I'm using Windows 10.

I have Nero 7 installed and mine definitely is not coming back with that. Can you please show me your product information without the serials? So I can compare what I may be missing. I did a full install

[madshi]

eac3to needs the Nero decoder to be accessible via DirectShow. If it isn't, eac3to can't use it. So something seems to be wrong with the installation. I don't know how to fix it, though.

[TheLastOfUs]

well im installing Nero 7.11.10 now direct from Nero's archive.....so far this is a nightmare.

I extracted eac 3.31 just fine

[TheLastOfUs]

Yup..installed 7.11.10.0

Same crap.

I'm more than likely guessing this is happening because I'm using Windows 10 and Nero.

Maybe manually registering "NeAudio2.ax" with regsvr32 helps?

http://forum.doom9.org/showpost.php?p=1238209&postcount=7877

If it doesn't then I'm out of ideas.

[TheLastOfUs]

My nero is not installing NeAudio2.ax

No idea why. Reinstalled cleanly and uninstalled in Safe mode a few times.

[TheLastOfUs]

I don't have this file "C:\Program Files\Common Files\Ahead\DSFilter\NeAudio2.ax"

[TheLastOfUs]

Madhsi thanks for linking me to above. Seems that guy had the EXACT SAME PROBLEM as me. He was also missing NeAudio2.ax but didn't quite mention how he solved it (super annoying).

I will be less annoying and say I solved this easily by installing NERO MICRO/LITE with my Nero 7 key. I then registered the .dlls and it worked minus the .dll C:\Program Files (x86)\Common Files\Ahead\DSFilter\NeEacDec.dll (this didn't register under the elevated command prompt). Didn't need to do ANY of the registry stuff.

Now it works!

[TheLastOfUs]

I went ahead and updated the EAC3TO Wiki FAQ on this question. Should prevent repeats of this :)

[AYColumbia]

The DS filter issue with Nero 7 goes back to Windows 7 64bit. I found that if you install it on a Win7 32bit and then back up your DSFilter folder from C:\Program Files (x86)\Common Files\Ahead you can later use this to register/re-register the filters. After you install Nero 7, on Win 10 for example, you then copy your backed-up DSFilter folder to the one currently installed (this will also restore the ones that Nero install did NOT include). Then register all the .ax files using elevated privileges. I wrote a command file that I can "Run as Admin..." to do this, i.e.,

@echo off
@cd /d "%~dp0"
for /f "delims=" %%i in ('dir /b *.ax') do regsvr32 "%%i" /s

I think way back I had done an install inside a VM on a Win7 32bit just for this purpose; to grab the DSFilter folder. It was painful.

[filler56789]

For best AAC decoding you need:

(1) Nero 7 (Nero 8 won't work!)
(2) Nero HD DVD / Blu-Ray plugin

It was true several years ago... but ¿is it still true today? :confused:
¿Time for an overdue update?

[torturesauce]

I read on dcadec's github page that the program is now deprecated and its development will now continue through ffmpeg. Will this be implemented in a future edition of eac3to as well? In the meantime, how should I replace dcadec with the latest ffmpeg manually? And where can we keep track of the latest developments on the decoding of DTS formats?

[Sparktank]

I read on dcadec's github page that the program is now deprecated and its development will now continue through ffmpeg.

Hmm. Interesting.

https://github.com/foo86/dcadec/blob/master/README.md
This program is deprecated!

This decoder has been fully integrated into FFmpeg master branch and further development will continue there. Using FFmpeg (https://ffmpeg.org/) for DTS decoding is now recommended.

how should I replace dcadec with the latest ffmpeg manually?

I believe you can't. Madshi uses custom builds of lav/ffmpeg which he would need to update.

Only manual updates that don't cause lots of issues seem to be:
libFLAC.dll
libdcadec.dll
dtsdecoderdll.dll (although should be deprecated now; depending how far ff-dcadec has come)

And where can we keep track of the latest developments on the decoding of DTS formats?

The official git for FFMPEG (https://git.ffmpeg.org/gitweb/ffmpeg.git) shows a lot of activity (from foo86) for dcadec over his github page.

https://git.ffmpeg.org/gitweb/ffmpeg.git?a=search&h=HEAD&st=commit&s=dcadec

Thanks for pointing it out.

Will definitely have to keep my eyes open in the future.

[filler56789]

.......
dtsdecoderdll.dll (although should be deprecated now; depending how far ff-dcadec has come)

FWIW: I've been using a not-so-recent x64-build of MPlayer, and thus far, its ffdca has decoded okay all the DTS sample-files and audio tracks I have (principally DTS Express and coreless Master Audio) — so yes, me too thinks the Arcsoft DLL should be used only "as a last resort", from now on... and preferably, without depending on DirectShow anymore...

The problem is that it's still an Atmos track. I'm trying to convert from Atmos to TrueHD.

[Music Fan]

I don't believe it's able to remove the Atmos part keeping only the THD part.

[duedel]

I just tested this:
ffmpeg -i "dtsHD_MA_track.dts" -bsf:a dca_core -c:a copy "dtsCore.dts"

Yeah, I found some 5.1 showing up bit-identical, with foobar2000 to bit-compare.

Except I've been converting to FLAC.

But I haven't tested anything over 5.1 yet.
Especially concerning 'strange setup'.

[canuckerfan]

I don't believe it's able to remove the Atmos part keeping only the THD part.

Dang... so there's no free method out there that will convert Atmos to TrueHD?

[nevcairiel]

Dang... so there's no free method out there that will convert Atmos to TrueHD?

Atmos is just additional metadata in the TrueHD stream, most players that don't support Atmos will just ignore it and decode the TrueHD parts. Why do you want to remove it?

[LigH]

Some software was not able to ignore the additional Atmos metadata correctly. But current versions of them should all be fixed.

[Weirdo]

Hi,

I have a question. I have been trying to demux the true-hd track from the BD Monster. Inc, and I am curious as to why the logs look this way.

Why does tsmuxer find one overlapping frame at most (but not all) the junctions between m2ts (seamless branching disk) while eac3to only finds 2 of them?
Also, I noticed that with eac3to 3.27, the number of frames processed is one less than when using 3.31. How come? 3.31 gives me the same number of frames with tsmuxer.

I understand. Here though there are warnings are in the log, so the identical frames aren't skipped (I am extracting the true-hd track). The log also says eac3to cannot fix the overlap. So in the output .THD file, the two identical frames are still here. What does that mean exactly? Are the two identical frames "next to each other"? Are they "on top of each other"?

I understand this has been discussed many times before, but I read pretty much everything related to that issue and there was never a clear answer.

Regarding the difference between eac3to and tsmuxer, any idea?

Thank you for your help.

[tebasuna51]

Here though there are warnings are in the log, so the identical frames aren't skipped (I am extracting the true-hd track).
Nope, identical 15 frames are skipped (case C in related thread), but there are 2 overlaps with different frames (case A).

The log also says eac3to cannot fix the overlap.
Without decoding the track we can only preserve both frames (the last frame of one m2ts and the first frame of next m2ts) or delete one.

Regarding the difference between eac3to and tsmuxer, any idea?

tsMuxeR removed 15 frames and:
TRUE-HD stream (track 2): overlapped frame detected at position 00:13:11,679. Remove frame.
...
TRUE-HD stream (track 2): overlapped frame detected at position 00:33:40,223. Remove frame.

eac3to:
[a03] Skipping identical AC3 frames (seamless branching)... (15 frames)
[a03] Audio overlaps for 5ms at playtime 0:13:12. <WARNING>
[a03] Audio overlaps for 5ms at playtime 0:33:40. <WARNING>

eac3to only remove a frame if there are a delay equal to the frame duration. Here we can finish with a +10ms delay.

I don't know the THD frame duration, but with AC3 frames (32 ms) delete the 2 frames for 10 ms of overlap we can finish with a delay of -54 ms.
