As far as I know it would only create an AC3 track from THD if there is no interleaved AC3 in the track to begin with. If there is it should just demux.

Thunderbolt8 · 4th October 2011, 16:22

but if I demux, dont get thd and ac3 seperated automatically? that is what I would want to avoid.

ss = Side
sr = Back

Looks like we're getting different results:

Code:

eac3to.exe  test-chan.dtshd channel.wavs

http://www.mediafire.com/?q9x6ovpz726waju

channel.SL.wav -> "beep… back left"
channel.SR.wav -> "beep… back right"
channel.BL.wav -> "beep… side left"
channel.BR.wav -> "beep… side right"

@tebasuna51 i can confirm that SL/SR are swapped with BL/BR...

I can't understand, here with:

Hmm - I got my Arcsoft decoder from a very recent TMT5 trial, and wondered how I could have ended up with version 1.1.0.0 (which seemed old) of the DTS decoder.

It looks like eac3to.exe isn't picking up TMT5's decoder, but an old version of dtsdecoder.dll (from 21/04/2008) which found its way to my C:\Windows\SysWOW64 folder somehow…

So I guess it's 1) a. then:

If not possible to convert thd to thd+ac3, is it possible to convert thd to dts-hd ma track without any quality loss? tsMuxer should have no problem with dts-hd ma track.

i can confirm that dtsdecoderdll.dll v1.1.0.0 (25 April 2008) is OK...

I've had this issue myself. I was using Ripbot, which uses eac3to, when the problem arose. No matter what I did I couldn't get the mappings correct so I used MeGUI and set it to NeroAAC to convert the DTS to AAC HE and no problems.

ramicio · 13th October 2011, 03:45

Is there any thought into being able to enter a dB gain in a precision other than an integer? The program can easily do it. If it detects clipping it applies a gain with a decimal, and it takes to below peak, so it's not just to get it to 0 dB.

I'm planning to install Arcsoft Total Media Theatre 5.0.1.114 (because it can play back Blu-Ray from folder). Is there a way I can have eac3to keep using the old 1.1.0.0 decoder? (which I had put in the eac3to directory itself, and registered manually). Or will the newest decoder work too?

Just came across a stream that eac3to lists as:

Code:

5: TrueHD/AC3, English, 5.1 channels, 48kHz, dialnorm: -27dB, 83ms

Does this mean it is delayed 83ms? So when I transcode I need to apply +83ms to the output?

asarian · 18th October 2011, 19:14

Still having major trouble with TrueHD audio (see below). Libav can't do it, Nero (the often suggested alternative) says it can't do it either, and Sonic can't even be bothered to try (as per the documentation).

This concerns the Gantz Blu-ray (Japanese Audio). Is there anything else I can try?!

As you can tell from my above post, that didn't work either.

Really seems an eac3to (libav) problem somehow, as nearly a quarter of all my TrueHD streams have eac3to abort somewhere (whereas they all appear to be pretty normal streams, that play with TMT 5, XBMC, etc., just fine). Never have this issue with DTS-MA.

Thunderbolt8 · 18th October 2011, 23:05

send a sample to madshi (try first if the same problem occurs with the sample)

Ok, I sent him a PM about it and a link to this file:

10sec Gantz sample

(I didn't see an option for attachments on PM's)

Now I'll just wait.

b66pak · 19th October 2011, 19:37

@asirian you can use this (demux the thd with eac3to and then decode it with the latest ffmpeg):

Code:

eac3to gantz_sample.m2ts gantz_sample_audio.thd

ffmpeg -i gantz_sample_audio.thd -acodec pcm_s24le gantz_sample_audio.thd.wav

get the latest ffmpeg from here...

Thanks, that totally worked!! You're a brilliant man!

This will no doubt help me in many other TrueHD situations too!

seems like eac3to needs an ffmpeg update
