eac3to - audio conversion tool

[j7n]

Thank you. Eac3to works as expected now.

[eac3to_mod]

Thank you for testing, gentlemen.

[eac3to_mod]

Build 3.41 is released.

v3.41

* Can now extract the AC3 core from EAC3 with sensible syntax and no re-encoding:
eac3to_mod in.eac3 out.ac3 -core. If -core is omitted, re-encoding will occur.
* Fixed some displays that gave wrong signs for dB.
* Extensions 'avc', 'mvc', and '264' are now accepted for demuxing in addition to 'h264'.
* Print 0dB in displays instead of -0dB.
* Changed the -showall option: If -showall is in the INI file, then all
playlists, including 'weird' ones are displayed. Without -showall
you get the previous 3.34/3.36 behavior. With the previous 3.40 -showall
behavior, some disks were showing no playlists without -showall. This is
fixed.

playlists, including 'weird' ones are displayed. Without -showall
you get the previous 3.34/3.36 behavior. With the previous 3.40 -showall
behavior, some disks were showing no playlists without -showall. This is
fixed.

It matches 3.36 only. 3.34 has -minPlayListRuntime and -maxPlayListRuntime which makes it possible to see playlists with playtime less than 10:00.

If you have access to 3.34 source, I am sure it's an easy fix since it was accidently left out of 3.36 completely. It was an extension of the original playlist sorting that allows to see all playlists regardless of length.

So just to confirm, if an app uses eac3to already (3.34 or 3.36), is it just a copy & rename to integrate this build ??

eg:- eac3to_mod.exe & eac3to_mod.ini to eac3to.exe & eac3to.ini ??

Yes, that files can be replaced, also the changelog.txt and libFLAC.dll (I always replace it from www.rarewares.org), the rest are the same than last madshi package.

I have now in my folder:

Thanks so much for the detailed explanation, teb :)

I am sure it's an easy fix since it was accidently left out of 3.36 completely. It isn't easy and it wasn't an accident.

[Sakura-chan]

I was wondering why eac3to was dropping all my last chapters and I found this:
last chapter is now removed, if it's less than 10 seconds from end of movie
Is there a way to reverse that? I see no command to preserve all chapters. Mkvtoolnix keeps all chapters, but I can batch extract them with it.

[Magister Irrylio]

I can confirm I have the same thing with Nemo.

I would try using this, but the link is dead.

Last chapter is not removed with latest version 3.42 of eac3to. Please update your build: https://rationalqm.us/eac3to

That's not the last chapter, that's the END of the file/movie. Chapter should have some content - that's why you have often named chapters on retail discs. You know, they are describing scenes, parts of the movie - like the first chapter for example named Intro/Credits etc.. This addition is not describing anything so it is not chapter. You got the same for End credits: main movie ends, [end credits start, movie/file finishes] <--- the last chapter.

I don't know why this was changed when eac3to got it right for all of those years.

[Ian1182]

Not sure if it's just me but I'm see a virus warning for eac3to.exe in the 3.42 rar file. My system is flagging the module for Trojan:Win32/Wacatac.B!lm , hopefully this is a false positive

[stax76]

You can try virus total:

https://www.virustotal.com

[Ian1182]

unfortunately its a fail there as well for 3 of the checks. I'll wait until a newer version of eac3to appears

[j7n]

You can try deleting HookSurcode.dll, thdmerge.exe, and maybe libmatrix.dll, and use eac3to without these features. But be reasonable. Nobody makes a virus that is a few kilobytes today. It has to do something useful for the owner, and report back through the web, which adds a lot of program code. The detections are vague suspicions.

I'm not sure what all that means... Is 'Wacatac.B!ml' okay or not?

[StainlessS]

You can be scared if you like, but M$ is not that reliable, is all based on security vender guesswork.

I once got a load of bad hits for a Visual Basic Lottery checker app (which I wrote), just because
it had a 7x7 grid of buttons for each ball number (in the days of 49 balls). I changed the order of drawing on form a little
bit and all the AV scareware agreed that it was OK.
3/72 is nothing to get yourself worked up about, their guesses are MOST LIKELY totally wrong.
[Although you may give them more credence if you think that Graft is a bit of a dodgy character :) ]

EDIT: Maybe Anti-malware stuff should also give a "confidence rating", eg 100.0% sure that its infected, for the real deal.
(not our Reel.Deel, he's 100.0% ok-ish)

EDIT: I think that 'susgen' is just 'generally suspicious', maybe was similar for my Lottery Checker.

'PUA' = 'Possibly Unwanted App', meaning very little evidence for panic if it was your intent to download a system tool.
(although it could be dangerous if is eg a password revealing tool, downloaded/used by some malware).
(PUA app might just do something a little bit non usual).

'Wacatac.B!ml', not the faintest idea what that is supposed to mean.

Security venders make their guess based on 'who knows what', you gotta make your guess based on number of security vender 'detects/guesses'.

[kedautinh12]

If you scared about only 3/72 softwares virus warning. Don't use it anymore. I still using cause 3/72 mean that ok with 69 antivirus softwares

[amayra]

Are there any devs interested in taking over eac3to development (bugfixes and improvements)? I'm considering open-sourcing it, because I don't have a lot of time for it now, and probably in the near future. However, eac3to is written in Delphi, and the code is not in great shape (due to constant lack of time). Plus, the source code might be more complex/long than many devs might expect, because of the simple reason that eac3to has a *lot* of features, some more obvious than others. In any case, I'm not going to spend any time on open-sourcing it if there are no devs who have serious interest in working on it.

do you still have plan to open-sourcing this project ?

i will help with this

[tebasuna51]

The source code is not open but released to other developers here: https://www.rationalqm.us/board/viewforum.php?f=18
