eac3to - audio conversion tool

[shon3i]

madshi any chance you could integrate an open source AAC decoder like libfaad2? I know Nero has better quality but is the difference really that dramatic?What you talking about. Both decoders follow aac standard, both have exatcly same bit indentical output. FAAD is used in foobar2000 and i don't see point someone need Nero Decoder while is there full free implementation.

I can't use libfaad2 because eac3to is not GPL and so I can't use any GPL libs. I can only use LGPL.
Maybe you can use CT AAC decoder from winamp??

[madshi]

Would you consider adding a flag like -simpleoutput to disable console text colouring and console character position handling ?
Again: I could do this. But have you actually contacted the Wine programmers about this? It's *their* bug and not mine. Why should I implement workarounds for other software's bugs?

Maybe you can use CT AAC decoder from winamp??
Is it a winamp plugin? I wouldn't know how to communicate with it in that case...

[honai]

If I do that, the next person will come and say: "You write Apple Lossless files, you should also be able to read them". It's a never ending circle, I guess...

Currently my focus is on madVR, so eac3to will have to make do with bugfixes and minor improvements for a while.

Ok, I understand.

A while back you mentioned that you were working or had implemented a plugin system for eac3to with support for plugging custom filters. Would that suit my needs (I'm a programmer myself)? Any documentation for it?

[dat720]

Fair enough, I just wanted to put forward some suggestions, your choice whether you run with them or not.

[shambles]

hooray! madshi!

i have the Freedom bluray set and i would like to remux the english versions but eac3to can't do it correctly, as the playlists use only parts of certain m2ts files. it's the only bluray where i've seen such playlists.

the main m2ts for each episode has the title sequence in japanese followed by the main body, so the japanese version uses the whole m2ts file, but the other language versions have their own title/credit sequence m2ts files, and only use the main body from the main m2ts.

i uploaded the japanese and english version playlists for the first disc here: http://www.mediafire.com/?sharekey=d0332f673c7857a5af924764f9977b1de04e75f6e8ebb871

[Kurtnoise]

@madshi : any chance to update the lavc lib ? there are EAC3 Spectral & AAC LATM patches floating around in the FFmpeg-dev ML...

[Xorp]

Hmmmm... I think I'm reporting dialnorm in the same way for both AC3 and DTS. Dialnorm is rare for DTS, anyway. Do you have a DTS track where you know for sure that eac3to's dialnorm information is incorrect? I don't have the disc anymore, but eac3to reported the US Warner version of Watchmen to have -4dB DN on the DTS-MA track.

[saint-francis]

BTW, Why couldn't eac3to handle this on it's own?

Sorry. I don't mean to be a pest, but, can anyone shed any light on this? I have little grasp on how I got that process to work, no idea why it didn't work out of the box and I'm concerned that I'll need to do it again and will again be dependent on the good souls on this forum.

[Guest]

I don't have the disc anymore We can't help you with this now, per forum rule 6.

My Aeon Flux Blu-ray shows something similar:

Did you compare SSRC with SoX Resampler (http://sox.sourceforge.net/SoX/Resampling) (GPL)? Code (http://sox.cvs.sourceforge.net/viewvc/sox/sox/src/rate.c?view=markup) is under active developement (http://sox.cvs.sourceforge.net/viewvc/sox/sox/src/rate.c?view=log) right now.

The SoX resampler's "VHQ Linear Phase" configuration looks virtually identical to eac3to's SSRC implementation in the comparison site linked to above. I don't have done direct comparison tests with real audio files, though. So I can't really judge. Why don't you compare for yourself?

eac3to cannot use SoX' resamplers because eac3to is not open source and thus cannot use GPL code.

I was little bit inaccurate, libsox is library under LGPL, so it can be used

[Chumbo]

You mean with MKV containers? That would not be easy because I'd have to add a full FLV bitstream parser. Possible, but too time consuming right now. Maybe somewhen in the future...
It's good to see you back. I hope you're doing well.

No not MKV but FLV files, i.e., file.flv that contains the video and audio stream. Using eac3to to get info and demux would be ideal, but you're right, you'd probably need a full parser for this. If you have time and decide to implement this in the future that would be great. Thanks for considering it.

Probably the Blu-Ray player fetches some additional information from somewhere else. Maybe the menus have it hard coded or something. eac3to reads out the default fields. If the information is not available there, there's nothing more eac3to can do.
SupRip can determine which subtitles are forced, with no other information than what is in the SUP file.

[jmonier]

SupRip can determine which subtitles are forced, with no other information than what is in the SUP file.

So can eac3to, but both it and SupRip use the forced flag which is not always there. Sometimes there is a separate subtitle track that is selected on the disc by means external to the track with no indication in the track (i.e. no forced flag) of it's function.

[9700PRO]

sorry but I forgot that this checkactivate.dll file is also required.


Atak_Snajpera please help!
checkactivate.dll file i didn't find. Where is he?
And please, give me advice - TMT 3.0.1.133 Patch doesn't exit anymore. Where is could be dtsdecoderdll.dll version 1.1.0.5.
Thanks you, very much.

[Paddy97]

Is there any way to demux DVB subtitles with eac3to?
I've tried several ways but get that the conversion is not supported. So if anyone can give me either a tip on a commandline or inform me if I am trying something that is impossible I would be happy.

eac3to shows the following when applying it to the DVB ts file so it can see the subtitles at least.

TS, 1 video track, 1 audio track, 4 subtitle tracks, 0:14:34, 50i
1: h264/AVC, 1920x1088 50i (30:17)
2: AC3, English, 2.0 channels, 192kbps, 48khz, dialnorm: -27dB
3: Subtitle (DVB), Swedish
4: Subtitle (DVB), Danish
5: Subtitle (DVB), Norwegian
6: Subtitle (DVB), Finnish

I have a problem with Pixar Shorts Blu Ray. It can see all the mpls but when trying to do a movie only, it cannot find anything about video, audio, subs etc.

It has 13 titles that are seamless branched which eac3to finds but that is far as I go. I have been using it with clown_bd but that is not the problem, as HdBrStream Extractor does the same.

eac3to v3.17
-----------------------------------------------------------------------
This playlist contains m2ts parts with different track properties (2). <WARNING>

[TinTime]

Is the first m2ts in the playlist a copyright message or something? Anyway, if this is the case you might have to do this the hard way and specify the individual files yourself, excluding the one that eac3to doesn't like.

eac3to.exe 00037.m2ts+00038.m2ts+00036.m2ts+...etc.

Thinking about it, you said this is Pixar Shorts. Are the playlists that don't work the "play all" ones? If so you could look for the playlists for each individual short instead and do them separately.

[nwg]

Yes it is the play all that do not work. Each m2ts is a short.

[TinTime]

Unfortunately in that case I think you're going to have to process each short separately. eac3to doesn't support track changes during processing.

[magic144]

@Paddy97 - have you tried extracting with the wildcard suffix, e.g. something like

eac3to 1) 4: subs04.*

that'd be my first guess anyway, I've never encountered this subtitle type before...

[Snowknight26]

That won't work. The usual extenion for subtitles is either .sup, .sup, .ass. Count try .dvb as eac3to allows you to extract unrecognized formats with an extension of the format name.. though in this case, eac3to does recognize it, so who knows.

[Paddy97]

@magic144 and @Snowknight26

Thanks for the tips. Still no luck though.

"This subtitle conversion is not supported. "

Is the reply I get. Might be a format issue and not a commandline issue after all.

[Snowknight26]

Seems like madshi hasn't implemented DVB subtitle demuxing, even though eac3to has a DVB subtitle reader.

Found the string "DVB subtitles are not supported yet." when digging through the exe.

[techstuff]

hi

i'am a newbie so sorry,
have been looking for days in the this thread for a way to make multi wav from 6 or 8 mono wav. (1 wav with 6 or 8 channel mono)
can you do this or is it only from other multi audio format like AC3 DTS etc.

and go from 23.976 and 25.000 fps audio to 24.000 (-slowdown, -speedup)

hope you can help.

thanks

[tebasuna51]

have been looking for days in the this thread for a way to make multi wav from 6 or 8 mono wav. (1 wav with 6 or 8 channel mono)
eac3to don't support multiple mono inputs.
Use Sox, WaveWizard, AviSynth methods, ...

and go from 23.976 and 25.000 fps audio to 24.000 (-slowdown, -speedup)
When input is audio we can't know the original video fps (because audio don't know the video fps), if you need change the audio duration you need include both original video fps and destination video fps like this:

eac3to input.ac3 output.ac3 -23.976 -changeTo24.000

With:
-speedup equivalent to: -23.976 -changeTo25.000
-slowdown equivalent to: -25.000 -changeTo23.976

hi

thank you tebasuna51 for your help and info.

Any News about the libav Lossless check failed on TrueHD Tracks with libavcodec ?

I would use Nero Decoder ,but teh Deocder doesnt work on Windows7 anymore

[PatlaborForce]

I would use Nero Decoder ,but teh Deocder doesnt work on Windows7 anymore

It works just fine on Windows 7 for me.

[ACrowley]

It works just fine on Windows 7 for me.

on W7 x64 ? How did you install it ?

Ah, now it works. I use standard NEro7 installer now (only Showtime). The BluRAy/HDDVD plugin is properly registered

Its a TrueHD+AC3 Track, now i get this :

Extracting TrueHD stream...
Decoding with DirectShow (Nero Audio Decoder 2)...
The DirectShow audio decoder didn't accept the input stream. <ERROR>
Aborted at file position 262144. <ERROR>

[PatlaborForce]

on W7 x64 ? How did you install it ?

The normal way you install Nero.

[ACrowley]

The normal way you install Nero.

yes, it works...eac3to finds teh Nero7 Decoder.
Can you decode TrueHD with it ?
The DirectShow audio decoder didn't accept the input stream. <ERROR>

EDIT2:
It works! i had to register the.ax manually

[DrNein]

Glad to see you back madshi. What is the status of the PGS subtitle issue regarding Decoder Time Stamp? Thanks.

[oddwunn]

Hi...I just got started using eac3to (thanks for this great tool, madshi!) and I have a real noob question.

Is this the correct Nero Blu-ray plugin that I want to use:

http://www.nero.com/enu/store-blu-ray-disc-authoring.html

If not, could some kind soul please direct me to where I can purchase the correct one?

[DrNein]

That's not it (and only for Nero 9 as well). It seems "BD/HD DVD Playback Plug-in" license is now only available in Asian-Pacific region and costs about $30 USD.

http://www.nero8.com/cht/store-blu-ray.html

[oddwunn]

Thank you, DrNein. If the Google translation is correct, I will be buying a serial number only. Is the plugin already installed in Nero 7, or do I have to find the file somewhere else?

[rica]

Welcome back to your home madshi, we'd missed you :)

[saint-francis]

Thank you, DrNein. If the Google translation is correct, I will be buying a serial number only. Is the plugin already installed in Nero 7, or do I have to find the file somewhere else?

It's just a serial #. You pop it in and you then can use the plugin.

[PatlaborForce]

yes, it works...eac3to finds teh Nero7 Decoder.
Can you decode TrueHD with it ?
The DirectShow audio decoder didn't accept the input stream. <ERROR>

EDIT2:

Yeah it works without having to do anything additionally.

[oddwunn]

Thanks, saint-francis...much appreciated!

[oddwunn]

Another newbie question - When I demux the the streams of a .m2ts file, I end up with subtitles that have the .SUP extension and chapters with .TXT extension, neither of which can be muxed into a .MKV container using MKVToolnix. What am I doing wrong?

Please note, if there is a guide somewhere that will explain all of this to me, I will gladly read it. The only guide that I found was the wiki, and it was not clear at all, or at least not to someone as new at this as I am.

[Inspector.Gadget]

MKVMerge doesn't handle BD-sup yet. Use Suprip to get a SRT or BDSup2Sub to get a VOBSub file.

Chapters files have to be selected in the "Global" tab, not the one where you drag and drop other streams.

[radius]

Hi guys,

I've been using clown_bd for ripping stuff and it looks like there an issue with the command line it uses to demux audio, -keepDialnorm is not being used on each track,
it results that some tracks keep the original dialog normalization and some get it removed...
Would there be any way, without encoding, to set the DN back in the tracks where DN was removed ?
Any possibility to get such function in eac3to ?

Thanks

[oddwunn]

Thanks, Inspector.Gadget! I tried both programs - Suprip had tons of unidentified characters, so it really was not useful, but BDSup2sub worked like a charm...much better...:)

And now I have chapters installed in my .MKV files...very cool!

[K1ngp1ng]

i noticed that eac3to isn't capable of removing dialnorm from dts master tracks. is this a known issue?
