eac3to - audio conversion tool

[Mark_A_W]

No, not a constant delay.

The audio varies from scene to scene, which must have been different m2ts file chunks. It's like the overlap correction is incorrect.

It used to work fine, but I haven't been able to figure which version it went wrong.

[Mark_A_W]

I get a correct result if I use MakeMKV tp make a MKV, then use eac3to to convert convert the audio from that to flac (then mux with mkvmerge).

I would like to start using eac3to again but I find that when I install Haali, it decides to take over my computer even though i untick everything when installing.

I don't Haali to be used for playback of mkv and ts/m2ts. Any suggestions how I can install haali without it taking priority? Filemerit doesn't seem to make a difference.

I use batch files to unregister all the dlls/ax files for both 32 and 64 bit environments. Then I just register the files needed for mkv when I need it in the 32 bit environment.

It looks like the "dictator complex" of Haali has been fixed in version 1.10.262.12 (2010/Aug/14). Except for the "generic" (Matroska) splitter, all its other components remain happily set at merit=0x00200000.

As for the playback of transport streams, I highly recommend the ArcSoft splitter and decoders. :)

Yes.
And lots of discontinuity errors. Then Video overlap errors.


But it then runs the second pass, which I thought fixed that.


Do I need to manually run a 3rd pass? (I'll have to talk to MikeEby about including that automatically in his Gui, if that is the case).


Thanks

yea I have done a few 2 in one encodes lately last was Anchoman: The Legend Of Ron Burgundy which had an authoring error where there was two of the same dreamwork clip intro in both of the .mpls files for the two runtimes. Anyway the disc uses branching obviously and when demuxing the video and audio and after encoding the video and adding the audio and muxing with mkvmerge there are no audio gaps via that method. I have noticed
that playback with mpc-hc of blu-ray discs with branching via the mpls file the audio is getting out of sync everytime a new m2ts file is played in the mpls.

I've already tried another pass with eac3to and the results are less than perfect.

Something else I have found out, if I simply demux the file with another program like TSmuxer, and then play the output files (which is badly out of sync at this point) but then manually adjust the audio sync in MPC HC to the exact number reported by eac3to when it scans the file (-650ms in my example file), then I get better results than if eac3to did the muxing to mkv which is supposed to take care of this offset! Even after all these multiple passes.

eac3to is nearly there, but I think I worked out what the problem is. eac3to needs to insert missing frames in the audio or video to maintain the correct timecodes to keep it in sync. For me it happens when the source file is not perfect.

@Midzuki

Thank you for the link. I appreciate the help. I will try these options out.

Any ideas?

[Thunderbolt8]

if the movie is in sync afterwards, dont care whats written there.

if not, try to add the .m2ts files (1+2+3...) manually instead of using the playlist.

[hoju3508]

Yes, it's in sync but TMT3 thinks it's a 13 hr movie for some reason. It's kind of odd.

if not, try to add the .m2ts files (1+2+3...) manually instead of using the playlist.

I might give this a try. Thanks.

[Dogway]

Hello, my source audio file is 25fps ac3 with 2 front channels and 2 rear channels. As for now Im using this code:
eac3to "input.ac3" "output.aac" -quality=0.30 -changeTo24.000 -down2 -phaseShift -mixlfe -resampleTo44100 -25.000
I want to enlength the audio to fit into the 24fps film, and downmixing all channels to Stereo 2. Does -phaseShift fix the pitch problem when changing audio lenght? and second, with this code I still have the 4 channels, how can I downmix them to 2?

I want to enlength the audio to fit into the 24fps film, and downmixing all channels to Stereo 2. Does -phaseShift fix the pitch problem when changing audio lenght?
Nope. BTW, don't use -phaseShift never with ac3 source.
And -mixlfe do nothing because don't exist LFE channel in the source
and second, with this code I still have the 4 channels, how can I downmix them to 2?
The -down2 parameter only work with 5.1 source.

You can use an .avs file like this:
a = NicAc3Source("D:\path\input.ac3")

# 4 Channels Quadro L,R,SL,SR, downmix to simple stereo
# flr = GetChannel(a, 1, 2)
# blr = GetChannel(a, 3, 4)
# MixAudio(flr, blr, 0.5, 0.5)

# 4 Channels Quadro L,R,SL,SR, downmix to DPL II
flr = GetChannel(a, 1, 2)
bl = GetChannel(a, 3)
br = GetChannel(a, 4)
sl = MixAudio(bl, br, 0.3714, 0.2144)
sr = MixAudio(bl, br, -0.2144, -0.3714)
blr = MergeChannels(sl, sr)
MixAudio(flr, blr, 0.4142, 1.0)

# [DSP: TimeStretch - 25 -> 24] pitch preserved
TimeStretch(tempo=96)

# [DSP: Resample SSRC - 44100 Hz]
SSRC(44100)

# [DSP: Normalize to 100%]
Normalize()
and encode with NeroAacEnc to .m4a with MeGUI, BeHappy or Wavi.

[Dogway]

Just WOW! it worked perfect. I didnt know I could load an avs into the audio input of MeGUI. Aside solving my issue, I just learned a little more, I hope this enlighting post awakes an interest on me on the audio part of the digital encoding.gracias:D

BTW what bitrate do you recommend me for medium quality towards good in m4a/AAC? something like 128,160 of mp3.

Also, in your script you are downmixing, normalizing,etc but in Megui the audio encoder also does its stuff in the Config options. Do I need to uncheck, keep originals everything from the options?

[tebasuna51]

...
BTW what bitrate do you recommend me for medium quality towards good in m4a/AAC? something like 128,160 of mp3.
To transcode from lossy sources (AC3,DTS,...) I always recommend at least -quality=0.35 (AAC-LC), with 0.30 you obtain AAC-HE, and is not always compatible with some players.
Also, in your script you are downmixing, normalizing,etc but in Megui the audio encoder also does its stuff in the Config options. Do I need to uncheck, keep originals everything from the options?
A little offtopic but ...
Yeep, you need uncheck all, or don't put Resample/Normalize in avs and use the Config options.
(These two functions are equivalent to eac3to, resample with SSRC lib).

The predefined downmix with MeGUI/BeHappy work only with 5.1 sources, like with eac3to. Then you need include the special downmix avs method for sources with 3,4 or 5 channels.

The change audio duration (for different fps video) in MeGUI only work for 23.976 <-> 25 using SSRC method without preserving pitch (like eac3to, but eac3to have more options).
To preserve pitch you need use the AviSynth function TimeStretch(tempo) included in BeHappy.

[deathlord]

I have just found something weird on "Fringe Season 2" BD. On disc three, the playlist for episode 14 "Jacksonville" is not listed by eac3to. It is relatively obvious that this must be 00072.mpls. Running eac3to on this file shows the right length (about 40 min), but instead of showing 00027.m2ts it shows 00027.m2ts+00027.m2ts and consequently demuxes files of double length.
With this length, eac3to should actually list this playlist aswell, but maybe there is an error in the playlist?
In any event, I just thought I would report this, perhaps somebody can make sense of it. Of course the problem can be solved easily by avoiding playlists for this episode and using the .m2ts file directly.

I have just found something weird on "Fringe Season 2" BD. On disc three, the playlist for episode 14 "Jacksonville" is not listed by eac3to. It is relatively obvious that this must be 00072.mpls. Running eac3to on this file shows the right length (about 40 min), but instead of showing 00027.m2ts it shows 00027.m2ts+00027.m2ts and consequently demuxes files of double length.

BDInfo shows the same. Also, 00075.mpls shows the same double file for 00023.m2ts. I think it's an error in the mpls files.

Hi!

Does the "Backup>>Playlist" sub-folder contain .MPLS files IDENTICAL to those of the primary "Playlist" sub-folder?

[Mark_A_W]

Is there anything that can be done to reduce audio sync issues with eac3to? It usually happens when I get a message like this...

v01 The MKV file was created without making use of the gap/overlap information.
v01 Please check whether audio is in sync. If it is in sync everything is fine.
v01 Otherwise ask eac3to to repeat the muxing. It will then automatically make
v01 use of the detailed gap/overlap information.

If I don't repeat the muxing then sometimes the audio can be really badly out of sync. It is not predictable how much. If I repeat the muxing as it says, it successfully makes the new MKV file without this error message. But then the audio goes out of sync by a small but very noticeable amount.

So repeating the muxing does do something but maybe eac3to needs extra help by having the file cleaned up by another program that can take care of the gaps etc before passing it on to eac3to? Any other ideas how I can stop the audio going out of sync?


Anyone having success (or failure..) with seamless branching titles?

Somewhere along the way they stop working for me - major audio sync issues, changing from scene to scene.

It's not clear if the automatic second pass is supposed to correct this, or if we need to make a manual third pass (and possibly manually compensate for an audio delay).


Umm..a little guidance? Please.

eac3to v3.24

[v02] [0:07:08] The source file seems to be damaged (sync byte missing). <WARNING>


I've gotten this before due to a bad rip (bad source).

[Mark_A_W]

I've gotten this before due to a bad rip (bad source).


I don't think that's it.

Every seamless-branching title has this issue.


They all play fine in TMT, and if I process with MakeMKV, they work fine.

[madshi]

Just a quick answer: "The source file seems to be damaged" is *NOT* supposed to appear for seamless branching titles. I've never in my whole life seen it on my PC with any seamless branching title. Try ripping to harddisk with AnyDVD HD first and then run eac3to on the harddisk folder.

[Jeff Flowerday]

Bad Source: I had the same problem recently with my Cars Blu-Ray. I waited for a new AnyDVD HD, just installed the release from a few days ago, and the problem went away.

Hi!

Does the "Backup>>Playlist" sub-folder contain .MPLS files IDENTICAL to those of the primary "Playlist" sub-folder?

They are not identical,
00072.mpls in the Playlist folder has md5
46612f7c8c248b74dde7c57ccad25a67

00072.mpls in the Backup\Playlist folder has md5
e9d5b291218c5409228547b9ebfcb0d2

However, the playlists are identical as far as eac3to is concerned:

eac3to Fringe_Season_2\FRINGE_SEASON_2_DISC_3\BDMV\PLAYLIST\00072.mpls
1) 00072.mpls, 00027.m2ts+00027.m2ts, 0:43:58
- Chapters, 9 chapters
- VC-1, 1080p24 /1.001 (16:9)
- AC3, English, multi-channel, 48kHz
- AC3, Portuguese, stereo, 48kHz


eac3to Fringe_Season_2\FRINGE_SEASON_2_DISC_3\BDMV\BACKUP\PLAYLIST\00072.
mpls
1) 00072.mpls, 00027.m2ts+00027.m2ts, 0:43:58
- Chapters, 9 chapters
- VC-1, 1080p24 /1.001 (16:9)
- AC3, English, multi-channel, 48kHz
- AC3, Portuguese, stereo, 48kHz

BDInfo shows the same. Also, 00075.mpls shows the same double file for 00023.m2ts. I think it's an error in the mpls files.

For my 00075.mpls it does not show a double file, at least not on disc 3.

Problem with ac3 conversion

Hi All:

I have a 25 fps PAL ac3 file I'm trying to slowdown to 23.976 fps so I can burn an AVCHD disc and play in my Bluray player. I do this regularly and have never had a problem. This file, although it plays fine in Media Player Classic, eac3to conversion hasn't worked.

When I looked at it more closely, it's characteristics differ depending on what I use to examine it:

MediaInfo for the mkv file (tsMuxeR does NOT recognize the audio track)
ID : 2
Format : AC-3
Format/Info : Audio Coding 3
Codec ID : A_AC3
Duration : 1h 27mn
Bit rate mode : Constant
Bit rate : 384 Kbps
Channel(s) : 6 channels
Channel positions : Front: L C R, Surround: L R, LFE
Sampling rate : 48.0 KHz
Stream size : 242 MiB (11%)

MediaInfo for the extracted audio track (using mkvextract)
Format : AC-3
Format/Info : Audio Coding 3
Duration : 1h 27mn
Bit rate mode : Constant
Bit rate : 192 Kbps
Channel(s) : 2 channels
Channel positions : L R
Sampling rate : 48.0 KHz
Stream size : 121 MiB (100%)

And eac3to sees the same extracted audio track as:
AC3, 5.1 channels, 0:44:00, 384 kbps, 48kHz, dialnorm: -22dB

Any ideas on what's happening here (or how to fix it)??

Maybe you have an AC3 with 2 kind of frames (a TV capture?, movie and commercials).

Try run:

SplitAc3 audio.ac3

and put the log file created.

[SoleBastard]

Hi Madshi,
Thanks again for your great program!

As eac3to doesn't support merging FLAC files (yet) I tried doing it using Foobar2000 and flac.exe 1.2.1. However, when the merged file reaches 2.00GB the encoding stops with an error. I asked about this in the Foobar2000 forum (see this thread (http://www.hydrogenaudio.org/forums/index.php?showtopic=84014)) and it seems to be a specific limitation of the Windows FLAC build. However you manage to create FLAC files with eac3to in Windows that are >2GB just fine. How is that possible?

[TinTime]

You could always convert to a .w64 file with foobar and then convert that to FLAC with eac3to. Not completely ideal but it's a workaround.

[SoleBastard]

Yep, I figured that out and doing the conversion at the moment ;)

So yeah, this work-around is okay for me because I don't need to do these kind of merges that often. I was just curious how Madshi was able to implement encoding >2GB flac files :)

[TinTime]

Yep, I figured that out and doing the conversion at the moment ;)

Sorry, I see now that I replied to something you didn't ask and ignored what you did ask :)

Anyway, from your link it looks like an i/o limitation in flac.exe, so that's why eac3to is ok - it handles i/o itself and uses libflac to encode.

[deathlord]

Often there's a "play all" playlist. It usually lists the episodes in the right order.

This is a very helpful hint, thanks a lot!
I have found it to work on Terminator: The Sarah Connor Chronicles and Dexter.

[Groucho2004]

Would it be possible to add an option to normalize to a certain level?
As far as I know, eac3to only normalizes to 0 dB. I always like to leave a little headroom for further conversions so that would be nice.

Possibly something like "-normalize -2dB".

[SoleBastard]

Ah right, that makes sense. :thanks:

A kind HA.org user modified the flac.exe to work with large input files and I find it to work perfectly with my FLACs! See the thread I linked to earlier.

You can certainly do "-2dB" (see first post). I don't know what happens if eac3to has to normalize, too. You can try it out or you can simply do two passes.

[b66pak]

"-normalize -2dB" this don't work (the -2dB part)

you must do:
eac3to audio.xxx normalized_audio.wav -normalize
eac3to normalized_audio.wav final-2dB_audio.wav -2dB
_

[shh]

Is there any way to prevent the massive file fragmentation in conjunction with eac3to?

I understand, that this is an issue of the (sometimes) unknown size of handled streams, but the count of segments of some of eac3to's files is just insane. :eek:

Suggestions:
- reserving file space for separate streams what can safely cover the size of a (sub)stream, later crop filesize to the real size of the stream.
- command line option: "just reserve +100MB per stream"
- ...?

[Groucho2004]

this don't work (the -2dB part)

you must do:
eac3to audio.xxx normalized_audio.wav -normalize
eac3to normalized_audio.wav final-2dB_audio.wav -2dB
_

Sigh.

Yes, that's what I've been doing so far. However, I was asking if this feature could added so I don't have to do 2 passes (actually 3 passes, because the "normalize" function already needs 2 passes).

[LeXXuz]

I'm getting this error message when encoding an audio stream:

Does anyone have a .bat/.reg file that would allow me to right click on a .mkv file and have it call a .bat file to automatically convert dts to ac3? I don't want to use a gui.

If not can anyone help me with creating a bat file that I run to convert dts to ac3?

Thanks.

Why not just use the cmd? At bat file wouldn't work for all instances since the track number of the dts is a variable. Well you could use mediainfo cmd to determine the track number for the dts and use that in the bat file but that would be more work than using eac3to cmd.

eac3to input.mkv track: output.ac3

If you must use a bat file here is a quick and dirty. It only works with mkv, single audio track, and doesn't allow for additional options. Hence the reason why using the cmd is a better approach.

Thanks for the reply. I should have mentioned that my mkv files only have (1) dts track and I don't use any options. I use cmd: eac3to input.mkv input.ac3
I'll take a look at the script you posted to see if I can make sense of it. Thanks again.

Ideally, I wanted to right click on a mkv file from the context menu, pass that file to a bat script to automagically create the ac3 output. I do a lot of ripping and converting. This cmd part is getting a little old. Just must be getting lazy.


Edit: I agree, that if I have to type the source input in everytime, then it doesn't make much since to use a bat file. I was hoping I could run it and it would locate all the 'mkv files I have and spit out ac3 files with the same input name and the mkv. Maybe I am asking for too much. I can't believe no one else has a need for this though.

If only I could use wildcards: eac3to *.mkv *.ac3
something like that

I think the reason most people don't need something like that is because if they needed ac3 then they would have converted the audio to ac3 before muxing to mkv. Not after the fact.

I see. I use handbrake to do a lot of my encodings. It keeps the dts but does not convert to ac3. It seems that I need to run my encodes through mkmerge anyhow for proper playback on my video boxes. I did find an old script in this thread from Snowkight26, that I was able to modify for my needs. Thanks again for the help.

Assuming there is only 1 video and 1 DTS track:


for /f "delims=;" %%a in ('dir *.mkv /b /s') do {
eac3to %%a 1: %%a.video.mkv 2: %%a.ac3
mkvmerge -o %%a.DTS.mkv --language 1:eng --default-track 1:yes -d 1 -A -S %%a.video.mkv -a 0 -D -S %%a.ac3 --track-order 0:1,1:0
del %%a.video.mkv
del %%a.ac3
}
pause


Something like that at least.

I modified this script to just convert dts from a mkv to ac3. I had to use quotes and change { } to ( ). Now I am trying to figure out how the mkvmerge portion of the script works. I seem to be having a problem with it. Can anyone help me out. It's a very powerful script at least for my needs.
