Why remapping channels?

Because the DTS internal channel order is different than standard WAV order.

Analysis of blu-rays got slower

Hi,
I noticed a performance decrease in reading the blu-ray structure compared to an older version of eac3to. Consider these automated commands:

eac3to.exe f:
eac3to.exe f: 1)
eac3to.exe f: 2)
...
eac3to.exe f: 5)

The output of the first line is used by a program in order to determine the number of titles on that disc. Let it be 5, for example. Then it analyses all titles automatically. Version 3.18 can do these commands in around 400 seconds, while the latest version 3.24 needs around 490. I get similar results with all my blu-rays.

Any ideas what's causing this additional time?


Best regards,
Andi

Hi,

not directly an eac3to question, but the reason for this question is the eac3to bug when downmixing 6.1 to 5.1 and the need to decode and downmix manually: I think and hope that you can help me with this question:

I found these channel orders for 5.1 respectively 6.1 flac files:

5.1 FL, FR, C, LFE, SL, SR
6.1 FL, FR, C, LFE, BC, SL, SR

Are these channels orders, which I got from ffdshow as audio audio processor from and searching for them in the internet, correct ?

Thx in advance, NanoBot

But is possible also:

6.1 FL, FR, C, LFE, BL, BR, BC

but madshi know the problem, is only a bug that can be solved with a new version ...

Hello,

can anyone tell me what decoder to use for 2-channel DTS Express tracks? I've tried using Arcsoft 1.1.0.0, 1.1.0.8 and Nero 7 decoders, and they all produce different results. Stereo WAVs from Arcsoft seem to be identical, except for 1 byte difference every few kilobytes (checked using HxD). Nero 7 gives a totally different stream. Which one to choose?

Can the difference be caused by different versions of Windows? I have Arcsoft 1.1.0.8 on a Windows 7 x86_64 PC and Nero 7 + Arcsoft 1.1.0.0 on a Windows XP x86 PC. However they both decode e.g. DTS-HD 5.1 files identically.

afaik dts express is not supported by any of encoder (which eac3to uses)

edit: or I am wrong (guess I am) and its only that mkvmerge doensnt support muxing it.

Thunderbolt8,

I was talking about DEcoders, that work with eac3to. I have a Stereo DTS Express track, which I want to decode using eac3to. And my problem is, that all three decoders output different WAVs. However, you are in a way right, because I intend to compress it and then mux to a matroska file.

Somewhere in the middle of this giant thread madshi talked about using Nero decoder on files, which Arcsoft doesn't handle. But all three decoders produce audio without an error, at least the program doesn't show any + I hear sound on playback, not silence or some random noise, etc.

Hi,

Having a bit of difficulty downconverting the sound track to 'Faster' to 16-bit. After processing with the -down16 switch, the eac3to log indicates that the DTS-MA track is a constant 20-bit. Is there a way to get eac3to to downconvert 20-bit to 16-bit and not assume 24-bit?

Hard to say without seeing the log, but it probably is a 24bit file, it's just that the actual audio data contained in it is only 20bit. I don't think the initial bitdepth has much influence on the speed of the processing, but tebasuna51 will probably know better than me. If your target format isn't lossless you can skip the downconversion to save time.

You are right in that it is a 24-bit file and that the actual audio data is 20-bit. I'm asking if there is a way to down-convert to 16-bit from the 20-bit data. As it is, the -down16 switch treats the file as though it has 24-bits of audio data.

I can't understand your problem, use -down16.

The uncompressed audio data are stored in 2 bytes for 16 bits and in 3 bytes for 24 bits, don't exist a especific 20 bits storage, when eac3to say is 20 bits means than the 4 less significants bits, from the 3 bytes/24 bits, are always 0.
Here down-convert from 24 or 20 bits is the same, forget the less significant byte.

So this doesn't apply to 20-bit audio files padded to 24-bit?

can you demux to a destination directory instead of the eac3to directory?

Yes, you can. Here's an example for demuxing a video stream from a blu-ray:
Code:
eac3to.exe F: 1) 2: C:\my\destination\directory\movie.mkv
That's the simplest way. But if you demux several streams at once, you have to type the path for every stream. That's a lot of work.
Instead, you could append the directory of eac3to.exe to the PATH environment variable. Then eac3to works from every directory, e.g. your desired destination directory. And you can specify filenames as you've been doing all along.

If you use something like this then eac3to will demux to the specified directory:

Code:
eac3to.exe source "C:\my\destination\directory\movie.*"

I'd suggest Another EAC3to GUI Plus for that. Works beautifully.

Oh nice, that works even better.
