So i shouldn't have any problems with a seamless branching movie with no over gaps using wav output?

I always convert TrueHD to wav with eac3to and haven't encountered any problems, seamless branching movie or otherwise. The only possible issue is the one that eac3to warns you about - oversized (>2GB) wav files. As you're converting the wav to w64 with eac3to that doesn't matter though as it handles large wavs.

Yep. As tebasuna51 said wav is the best bet for an intermediate file in this case (it's just pcm data with a header describing it stuck at the front).

Thanks for your response that's exactly what i wanted to hear.

TSmuxer also accepts large .wavs. I tried 7GB wav and it was correctly muxed to .m2ts

So in fact we don't have to use .w64 for now.

When eac3to outputs wavs all I used to get was sound for the first 15-30 minutes then white noise.

If is correct is a new and undocumented feature. But this is the eac3to thread.

The audio data in wav is ok, maybe your player can't play it.
There are many soft to manage wav files >4GB (encoders, AviSynth, ...)

Hello,

i have a problem with dts-es matrixed files.

If i try to create the waves from the source file with:

Code:

X:\temp>eac3to demo.dts c:\temp\demo.wavs
DTS-ES, 5.1 channels, 0:01:55, 16 bits, 755kbps, 48khz
Decoding with ArcSoft DTS Decoder...
Patching bitdepth to 24 bits...
Writing WAVs...
Creating file "c:\temp\demo.R.wav"...
Creating file "c:\temp\demo.L.wav"...
Creating file "c:\temp\demo.C.wav"...
Creating file "c:\temp\demo.SL.wav"...
Creating file "c:\temp\demo.LFE.wav"...
Creating file "c:\temp\demo.SR.wav"...

Everthing works fine.

But i want that 7th channel so i use the -7 cmd to force the extraction.

But i doesn't work:

Code:

X:\temp>eac3to demo.dts c:\temp\demo.wavs -7
DTS-ES, 5.1 channels, 0:01:55, 16 bits, 755kbps, 48khz
Decoding with ArcSoft DTS Decoder...
Patching bitdepth to 24 bits...
Writing WAVs...

Eac3to only creates a log file and interrups.

Here the content of the log file:

Code:

eac3to v3.16
command line: eac3to demo.dts c:\temp\demo.wavs -7
------------------------------------------------------------------------------
DTS-ES, 5.1 channels, 0:01:55, 16 bits, 755kbps, 48khz
Decoding with ArcSoft DTS Decoder...
Patching bitdepth to 24 bits...
Writing WAVs...

Every other file i had tested worked fine.

Here is a little part of that file so you can test by yourselves.

DL: http://rapidshare.com/files/244067335/demo.dts

##EDIT

With Sonic it doen't work, too!

Code:

eac3to demo.dts demo.wavs -sonic
DTS-ES, 5.1 channels, 0:01:55, 16 bits, 755kbps, 48khz
Patching bitdepth to 24 bits...

Code:

eac3to demo.dts demo.wavs -sonic -7

With libAv it's the same. Only 6 channels.

Is it possible to downmix a 2/2 recording (an old quadrophonics with L-R-SL-SR) to stereo?

The -down2 option leaves it as a 4-channel recording.

-7 don't force to extract 7 channel (-7 means the pcm input have 7 channels)

Like you see is a 5.1 and the BackCenter channel is an analog matrix mix in BackLeft and BackRight channels.

There are other kind of DTS-ES with a discrete BackCenter than can be extracted, eac3to inform with this message:
DTS-ES, 6.1 channels, 0:00:22, 16 bits, 1510kbps, 48khz

Tarnatos · 14th June 2009, 09:23

Than it is not possible to extract the matrixed backcenter channel?

For what?
You can play the 5.1 and the phantom BackCenter is there.

BTW, you can try to make a stereo with BL,BR and use a dpl decoder to 5.0, the new FL' is the original BL, the new FC' the original BC, and the new FR' the original BR (the news BL', BR' must be empty).

To do this conversion you can use Foobar2000 and the foo_dsp_fsurround.dll plugin.

Hello!

I'm using eac3to 3.16. I have 7.1 TrueHD audio track. I'm trying to recode it to flac or to wavs, but I get such error:
eac3to.exe 00003.track_4352.ac3 audio.wavs
TrueHD/AC3, 7.1 channels, 48khz, dialnorm: -27dB
(embedded: AC3, 5.1 channels, 448kbps, 48khz, dialnorm: -27dB)
Extracting TrueHD stream...
Removing TrueHD dialog normalization...
Decoding with libav/ffmpeg...
Remapping channels...
Writing WAVs...
libav Invalid channel 13 specified as output from matrix
The libav decoder reported an error while decoding.
Aborted at file position 262144.

I understand that it's problem of audio track or decoder, but may be there is some work around in eac3to?

I've made sample of the audio: http://rapidshare.com/files/24440854...track_4352.ac3 (105 MB)

Or maybe the tool used to extract the track (.ac3 with thd content?).
Let eac3to extract the track to the flac or wavs from the container.

The track is .ac3 only because it was demuxed by tsmuxer. I have also tried eac3to in two ways: decoding from BD directly and demuxing from BD (thd+ac3) and decoding to flac or wavs. Just the same error.

But eac3to can't imagine a TrueHD when say:

Code:

eac3to.exe 00003.track_4352.ac3 audio.wavs
TrueHD/AC3, 7.1 channels, 48khz, dialnorm: -27dB
(embedded: AC3, 5.1 channels, 448kbps, 48khz, dialnorm: -27dB)
Extracting TrueHD stream...

Then the stream is corrupt

odin24 · 15th June 2009, 04:10

Has anybody encountered this before? If so, is there anyway around it? I've examined all of the m2ts files in the two playlists with tsMuxeR, each branch has identical streams within the whole playlist... both 1) and 2).
Thanks.

setarip_old · 15th June 2009, 05:31

There are two observable differences:

1) A total 13 second time difference

2) Different sequence of the audio tracks

What is the title of your BluRay disc?

mrr19121970 · 15th June 2009, 07:52

@odin24

why have you blanked out your name in 3 out of 4 C:\Users\XXXXX> ?

and yes, I saw it yesterday. With the 'March of the Pengiuns' German version, Kinowelt have added a 13 second trailer to the start of the film. There were 3 playlists all with 00026.mts (from memory). The chapter points are different.

1) 1:22:26 mins long one with the trailer.
2) can't remember
3) 1:22:15 mins long - was clearly the original film without the trailer

However on demuxing either 1) or 3) I always got the longest version.

Here are the logs...

I get the same results as you using eac3to on CJ7. I'm trying to back it up using BD Rebuilder (movie only). The movie only result would play with PowerDvD but not my Sony standalone (audio, subtitles, but no video).

eac3to v3.16

eac3to (v3.16) is installed
Nero Audio Decoder (Nero 6 or older) doesn't seem to be installed
http://www.nero.com/eng/store-blu-ray.html
CAUTION: You need Nero 7. Nero 8 won't work with eac3to.
ArcSoft DTS Decoder (1.1.0.0) works fine
Sonic Audio Decoder (4.3.0.169) works fine
Haali Matroska Muxer doesn't seem to be installed
http://haali.net/mkv
Nero AAC Encoder (1.3.3.0) is up to date
Surcode DTS Encoder (1.0.21.0) is installed
MkvToolnix (2.2.0.0, 2008-03-04) is installed

Of course I can use Sonic but I would love to use Nero inside eac3to. Can someone help? Many thanks.

And the log gives:
eac3to v3.16

------------------------------------------------------------------------------
AAC, 5.1 channels, 48khz
I'd like to use the Nero decoder, but it doesn't seem to work. <ERROR>

Madshi could you tell us a little bit on how eac3to checks for Nero Audio Decoder installation?
Maybe with some inputs from you I could check whether I meet your requirements. Thanks.
