eac3to - audio conversion tool

[poisondeathray]

Hi, I already have a Nero 8 installed yet the program keeps failing to open Nero Audio Decoder 2 (I am trying to convert AAC audio into AC3) and it just keeps blaring a siren in my ear every time I try

What gives? My nero is registered.

From Page 1:



For best AC3, E-AC3 and AAC decoding you need:
(1) Nero 7 (Nero 8 won't work!)

[Joniii]

I'm confused. My TrueHD track has +200ms delay. I converted it to DTS with EAC3TO. Do I now need to apply negative or positive delay with EAC3TO or leave it as it is? :confused:

[sshd]

Do you have the arcsoft bin directory in your path in the cygwin environment?

I didn't, but it seems to be the cure.

[nautilus7]

It's been said a million of times. TrueHD bitstream can't be delayed. Only when converting TrueHD to another format it can be delayed.

I'm confused. My TrueHD track has +200ms delay. I converted it to DTS with EAC3TO. Do I now need to apply negative or positive delay with EAC3TO or leave it as it is? :confused:If you just demux the TrueHD stream, the delay can NOT be applied.

If you decode (aka convert to another format) the TrueHD stream, then the delay IS applied.

This is the case ONLY with TrueHD. EVERY other format can be delayed.

I still dont quite understand it. I demuxed TrueHD and EAC3TO said it has +200ms delay. After demuxing I decoded it to DTS. But should I now apply delay fix for the DTS?

[nautilus7]

Yes you are able to apply the delay then.

What i mean is that you can tell eac3to create the dts track from the truehd without first demuxing it. In that case the delay will automatically be applied.

@madshi: is there any way to host an eac3to wiki somewhere?

Thx :). Could I fix the delay in DTS with EAC3TO so I wouldn't need to do surcode encoding again, if so I would need to apply delay +200 in it or -200?

EAC3TO said that TrueHD had +200ms delay in .EVO.

EAC3TO said that TrueHD had +200ms delay in .EVO.If you have already demuxed the truehd file do:

eac3to input.thd output.dts +200ms

If you haven't demux the truehd file do:

eac3to input.m2ts #: output.dts

where # is the number of the truehd stream.

If you don't understand it now, it might be better someone else to explain. Perhaps he/she can explain it in a different way. :)

I'm confused. My TrueHD track has +200ms delay. I converted it to DTS with EAC3TO. Do I now need to apply negative or positive delay with EAC3TO or leave it as it is? :confused:
You can apply delay (negative/positive) to DTS/AC3 streams with DELAYCUT program.

[Joniii]

If you have already demuxed the truehd file do:

eac3to input.thd output.dts +200ms

If you haven't demux the truehd file do:

eac3to input.m2ts #: output.dts

where # is the number of the truehd stream.

If you don't understand it now, it might be better someone else to explain. Perhaps he/she can explain it in a different way. :)

Yeah I get it now, I need to add delay +200 to the DTS.

I was just confused if I need to add or remove delay if I do it manually.

[nautilus7]

Yeah joniii, i 'm sorry. I didn't get what you asked in your last post. I understood your point right after i wrote my response, but couldn't edit it because my internet connection was giving me troubles. Sorry.


You can do eac3to iput.dts output.dts +200ms to fix your track.

[ACrowley]

WOW ! Nero 9 Decoders are working outside Showtime!

You have to reg. them manually in C:\Program Files (x86)\Nero\Nero 9\Nero ShowTime

Working in Graphedit and MCP etc

Also Nero Showtime 9 works so nice on any HD Audio Format :) Great Sound ,plays TrueHD, DTSHD, EAC3 ,LPCM, DRC can be disabled in Showtime
And m2ts/EVOS are playing very smooth with dxva
eac3to with Nero 9 Decoder gives me missing MSCVR71.Dll Error. It works After downloading mscvr71.dll, but eac3to cant find the Decoder, ofcourse.
However... Nero Filters/Decoders outise Showtime have the old DRC/Dialnorm Problem ...it cant be disabled

Maybe Madshi can take a look. But its no Problme. You can install Nero9 and Nero7 at the same Time. Nero 9 DshowFilters are not reg. by default (unless you do it by yourself),so theres no Decoder confusion.

[nautilus7]

What do you mean that manual registration is needed? Just installing nero 9 and the plugin isn't enough?

[ACrowley]

The Filter/ Decoders/.ax are not registered in the Dshow Engine.
You have to register them manually.

Nero7 Filters are registered by default

[lexor]

Nero7 Filters are registered by default
Can you register them one at a time or all at once? If madshi ends up supporting it (with DialNorm/DRC removal, like he did for Nero 7), then I would like to get the (E)AC3 decoder (for which I currently use libav), but I don't want any other decoders to be registered at all, since I have everything else set up the way I want it and don't want to upset the balance.

So does Nero 9 allow us to pick and choose which filters we want to register and pretend the rest don't exist?

one at a time... there are a lot of .ax Files.
Every .ax File is one Decoder ,ofcourse. Nothing different from other Directshowfilters

NeAudio2.ax =NeroAudioDecoder2 .
It can decode´ac3,eac3,dts,dtshd,truehd,aac3,mpeg etc etc

BUT outside Showtime "with" DRC/Dialnorm. The old Problem:)

[lexor]

NeAudio2.ax =NeroAudioDecoder2 .
It can decode´ac3,eac3,dts,dtshd,truehd,aac3,mpeg etc etc
aww, so it is an all in one audio decoder :(


BUT outside Showtime "with" DRC/Dialnorm. The old Problem:)
That is the case with Nero 7 too, but madshi found a way to deal with those. He might do that again.

[ACrowley]

aww, so it is an all in one audio decoder :(

yes, but you can configure a Directshowplayer to use the Decoder only for your desired Formats.
Or you can tweak the registry.
But imho its useless because you get full DRC/Dialonorm outside Showtime. You cant set DRC in NeoAudioDecoder2 Properties. Only NeroShowtime has Options for DRC

That is the case with Nero 7 too, but madshi found a way to deal with those. He might do that again.
Ofcourse.....but only in eac3to:)
You still have DRC/Dialnorm in any Dshowplayer outside eac3to

I dont know if its worth it. Nero7 is fine. I dont belive the eac3 decoding quality is better in Nero9. And we dont need NEro to decoder for TrueHD,DTS(HD),Flac, etc. Only for eac3 to
So its not worth to tweak Nero 9 imho.

When you need Nero9, you can install v7 and v9 together on one System without Problems (so far you dont register Nero9 .ax Files). Nero 9 works 100% with all Functions .
i have a full install of Nero9 for burning,showtime etc and only the Showtime Part from Nero7 to work with eac3to

PS
Ive to say it again: My English is very bad. SRY

By the way, only the extraction of the audio track(s) should be repeated. It's probably slower if the entire extraction process (video, audio, subtitles) is repeated just to get audio right.
Nope :) Sometimes video contains gaps as well

Which Blu-ray tracks needed channel remapping, was it only PCM?

[baudi]

How can I convert a 25fps audio track to exactly 24fps.

Note: I mean 25fps to 24fps, not 25fps to 24000/1001 with the -slowdown option.

Thank you.

[rica]

Hi guys.

I'm a little bit confused.

For Blu-rays which include multiple workflows (lets say titles)
and multiple m2ts files for every title, how do i know what title is related with what *.mpls?

For instance when i write this code:

C:\>eac3to\eac3to.exe G:\HDBACKUPS\CETK 1)

As expected i get only the track information of that title:

M2TS, 1 video track, 2 audio tracks, 20 subtitle tracks, 2:17:13
1: Chapters, 20 chapters
2: h264/AVC, 1080p24 /1.001 (16:9)
3: TrueHD/AC3, English, 5.1 channels, 48khz
4: DTS Master Audio, English, 5.1 channels, 24 bits, 48khz
5: Subtitle (PGS), English
6: Subtitle (PGS), English
7: Subtitle (PGS), Dutch]

How can i see the workflow for any specific title number like this:

1) = / ? 00059.mpls [00000+00002+00006+.....].m2ts
2) = / ? 00052.mpls [00000+00001+00009+......].m2ts

Thanks.


Note: when i use bdinfo i can see the mpls files and their workflows of m2ts' but i'm not sure the first mpls is 1)

Hi, sorry if this question has already been asked, but I got the following error from eac3to, and dont really know what to do about it.

it occurred while trying to backup a Blu Ray.

Is this a problem with this Blu Ray, or an issue with how I am using eac3to? I have backed up many other disks in my collection, and this is the first time this has happened to me.

"
Unfortunately the Haali Muxer cannot handle this source file.

that's very little info, since we know nothing about what you are working with (avc/vc1/mpeg2 and same question for audio).

But try -seekToIFrames option, could be just that simple. (if your source is avc video)

[Jaja1]

How can i see the workflow for any specific title number like this:
Use the command "eac3to" without any options from anywhere in the blu-ray folder and you'll get what you want.

You can easily find what is the content of each playlist file by playing the corresponding m2ts files in a media player.

eac3to doesn't show any playlist shorter than 15 minutes. That applies to HD DVDs and Blu-ray Discs as well.

OK, thanks a lot; i've been about to get lost between 300 pages. :)

EDIT: Everyday i learn a new tip/trick; that is why i love eac3to as well. :)

OK guys,
another history of mine:

today i loaded 00056.mpls to TSMuxer and i got an m2ts which including true hd and dts-hd ma.
I left true hd since eac3to doesn't correct the gaps and i got dts-hd ma corrected in second-pass; no problem.
Then as advised i directly tried to transmit true HD to PCM.
This is what i got:

Sure, those pcm files have to be re-processed by Pcm2Tsmu (by tebasuna51) so as to be recognized by TSMuxer:

C:\>Pcm2TSmu13\Pcm2Tsmu C:\HD\audio.pcm C:\HD\audio_out.pcm -i 24

[rica]

All those experiences teach us again:
Remuxing of BDs including multiple m2ts files with TSMuxer doesn't correct or remove the gaps/overlaps; so they have to be re-processed by eac3to,
eac3to can not correct gaps/overlaps of True HD files on those BDs, so they have to be transmitted to any other uncompressed or lossless files like pcm or wav or flac.
Created re-encoded files as pcm have to be re-processed with pcm2tsmu again so as to be recognized by TSMuxer.

@madshi: what programming language is eac3to written in? I'm also curious as to the available hooks into the code. Is everything done via StdIn/StdOut?

[madshi]

There's a problem with AGM files.

DTS Pro Encoder will accept all AGM files made from DTS-HD Master Audio tracks, but will reject every single AGM file made from TrueHD tracks
if the decoded TrueHD track is less than 4GB the problem is not there.
Thanks, will check that out.

Can you add MKV to "Supported source formats" ? PLEASE ! :helpful:
Maybe some day. But probably not anytime soon.

Did anybody ever experience the following error and has found a workaround?

Correct. And your best bet is to rerip the disc. Should be no problem if you actually own the disc. Which you should... ;)

FLAC, 7.1 channels, 1:26:32, 24 bits, 5095kbps, 48khz
NeroAacEnc only supports 6 channels. Will mix the surround channels.
Nero supports 7.1 encoding. :confused:
Yes, the new version (which is just a few days old) does. The old version did not.

madshi, it would be nice if eac3to displays the profile of the AAC file (LC, HE, HEv2), runtime and the bitrate even in vbr tracks, like it's done in flac.
I don't know how to get this information. For FLAC it's easy cause all the info is in the header. But raw AAC streams don't have a header like that (AFAIK).

WOW ! Nero 9 Decoders are working outside Showtime!
Nice! Can you create an XML graph (GraphEdit) and post the XML text here, please?

Nope :) Sometimes video contains gaps as well
That's the first Blu-Ray I've seen which has video overlaps in it! Do you see any difference in the video playback smoothness when you let eac3to fix vs. not fix the overlaps?

Which Blu-ray tracks needed channel remapping, was it only PCM?
If you let eac3to do the demuxing/transcoding you don't need to worry about things like that.

How can I convert a 25fps audio track to exactly 24fps.
Currently not with eac3to. It's on my to do list.

Hi, sorry if this question has already been asked
It has. Please search for "seekToIFrames".

@madshi: what programming language is eac3to written in? I'm also curious as to the available hooks into the code. Is everything done via StdIn/StdOut?
eac3to is written in Delphi. What do you mean with "hooks into the code"?

[madshi]

eac3to v2.66 released

http://madshi.net/eac3to.zip

* fixed AGM creation for files bigger than 4GB
* changed eac3to to allow AAC encoding with 7.1 channels (for new Nero encoder)
* added support for Nero's new AAC Encoder download URL
* lowered volume of error/success sounds
* when there are 2 similar playlists the one with less chapters is ignored now

[nautilus7]

Thanks madshi.

btw any fix for the mkvtoolnix update check?

[madshi]

btw any fix for the mkvtoolnix update check?
What's wrong with it? Seems to work fine for me.

[nautilus7]

Well, it always says there's a new beta available even if i have the newest version already installed. This happens with all versions of eac3to.
And i just saw that the date of the mkvtoolnix version is not displayed correctly with v2.66, while it did with older versions.

eac3to -test
Nero Audio Decoder (Nero 7 or older) works fine
ArcSoft DTS Decoder (1.1.0.0) works fine
Sonic Audio Decoder (4.3.0.169) works fine
Haali Matroska Muxer (2008-03-29) is up to date
Nero AAC Encoder (1.3.3.0) is up to date
Surcode DTS Encoder (1.0.29.0) is installed
MkvToolnix (2.3.0.0, 2008--04) is up to date
There's a new beta version (2.3.0.0, 2008-10-05) available

eac3to does not OCR the message box of the GUI, obviously, to get the version number. Instead eac3to captures what "mkvmerge --version" says. Sometimes that information is not correct or sometimes mkvmerge is simply older than the GUI. If that is the case there's nothing I can do about it. I won't add OCR to eac3to just to get the version number/date of the GUI!! It can happen that Mosu recompiled only the GUI or only mkvmerge in a new beta build. Since eac3to can only get the version number of mkvmerge, there is potential for incorrect reports. Can't do anything about that, unless Mosu adds programatically readable version information to the GUI, too.

And i just saw that the date of the mkvtoolnix version is not displayed correctly with v2.66, while it did with older versions.
That's a bug in eac3to. It doesn't understand "Oct" as a month. Will be fixed in the next build.

[rebkell]

Madshi, would it be possible on the discontinuities to also print the frame number in the message, in addition to the file pos?

[madshi]

That'd be hard to do because the layer of processing which detects the discontinuities doesn't know anything about audio/video frames...

[rebkell]

Ok, just thought I'd ask, I have them sometimes on the Hauppauge HD-PVR caps and it's difficult to figure out where the discontinuities are happening. I suspect most happen during commercials, but you never know.

If you ask eac3to to ignore the discontinuities, does demuxing/transcoding succeed then? And do you then get any audio or video corruptions during playback? Just wondering whether these discontinuities are the result of a buggy broadcasting setup. Or whether there is real corruption in the data?

[Jaja1]

Hi Madshi,

You probably missed my post, so here is my question again. What does the message "Lossless check failed" mean? And is the resulting DTS track in someway influenced by this?

They seem to vary, I recorded Sanctuary the other night on SciFi and eac3to reported 2 discons one at
3518061672
3518061860
and another at
7045026084
7045025896

on the rerun the first set at 3518061572 were the same and thethe ones around the 7GB mark it reported them in reverse order:
7045025895
7045026084

I muxed the audio you repaired back in and the first one which I'm assuming was the same as an audio gap of 750ms reported at 54:39 didn't appear to have any problems and the audio went out of sync.

You also reported an audio gap of 745ms at 1:49:07, which would probably coincide with the discon at the 7GB mark, there was definitely a problem in that area in the original, because that was where muxing originally caused the audio/video to go out of sync, and 745ms seems probably about right.

That explains. OCR is not needed of course, it's not important at all. Thanks!
