eac3to - audio conversion tool

[idbirch2]

I don't think VOB files ever contain chapter info. Certainly in a DVD structure, that information is in the .IFO file corresponding to the TitleSet. IFOEdit will extract chapter info from an IFO file for you.

First of all, many thanks to Madshi for his wonderful program. Now two ( probably stupid ) questions : when a m2ts file has more THD tracks what I have to digit to select only the second THD track?
Again; I have used various releases of eac3to but when I have a m2ts file like input it's never specified the language of the various audio tracks. I have tried also with -check but without success. Any help?

well, the problem is pretty obvious. Your command line is wrong and surely this is not the complete command line you use.

Mmhh...this was only to show the content of my bluray. I converted more than 30 bluRays and HDDVDS with eac3to - without problems.

The command I use to convert:

1)
eac3to h: 1) 3:bruce.mkv 6: bruce.ac3

2)
eac3to h: 1) 3:bruce.mkv 6: bruce.ac3 -libav

3)
eac3to h: 1) 3:bruce.mkv 6: bruce.wav


and so on.

The sample I made doesn't work for me in 2.74, says "The format of the source file could not be detected." but it's definitely the end of the file.

Do you have nero? Does it work? What is the exact error message you get? Do you have anydvd running in the background in case the disc is protected?

Nero: NO

AnyDVD HD: YES

ErrorMessage:
[libav] Spectral extension is not implemented. If you want to help, update your FFmpeg version to the newest one from SVN. If the problem still occurs, it means that your file has extension which has not been tested due to a lack of samples exhibiting this feature.

Ok, this pretty much explains what's wrong, huh? Libav doesn't support the track because it uses some special features of the e-ac3 standard. Nero will work though.

Anyway, for the good of our community i suggest you run the following command

eac3to h: 1) 3:bruce.mkv 6: bruce.eac3 -10mb

to create a 10MB sample of the track and upload it here, so it can be forwarded to the libav developer.

btw, which movie is it?

Thanks for your help.

The Blu-Ray Movie is "Enter the Dragon" in German: "Der Mann mit der Todeskralle".

I will create a sample - but how can I upload it!

btw:
I have a second problem with the Blu-Ray of "Kingdom of Heaven".

The Command is:
eac3to I: 1) 4: kh.dts

4: DTS Master Audio , German 5.1 channels 24 bits, 48 khz, (core DTS, 5.1 channels, 24 bits, 1536 kbps, 48 khz)

After a few minutes the message appears:
[a04] This track is not clean. Processing aborted.
[a04] Please clean the track with delaycut and then retry eac3to.

What does this mean?

You can upload it in a file host like sendspace.

This means that the track has some kind of corruption in it. Only possible way to fix this is to re rip the disc.
Do you need the master audio track or only the core? If the second, you can try the -core switch to see if it works.

P.S. I know there are other "tools" for demux all video and audio tracks of an mkv but I'd like (as many others) to keep things simple (and not having a lot of programs installed)

Damn. Obviously the corruption is on the origin blu-ray. -CORE won't work - same result.
What do you mean with re-rip? I have the Blu-Ray already on my hdd as ISO.

The sample you made is too small (only 96KB). Maybe it's not big enough (eac3to can detect its format though).
Do you have a slow connection and it's difficult to upload a bigger sample? If it's not a problem please make a 5 -10 MB sample.

Thanks.

How can be sure that the corruption is in the disc aswell? Maybe something went wrong the first time you ripped the disc. Rip the disc (either as iso or as folder) and try again.

Problem 1 (bruce-lee 1.0 ac3)
Sorry, obviously something went wrong. Here the 10mb-file:
http://rapidshare.com/files/161846249/bruce10MB.eac3

Problem 2 (kingdom of heaven)
I bought the bluray yesterday and after 2 times getting an error from eac3to by accessing to the BDROM direcly i ripped the whole blu ray to my hdd. Unfortunately, the error appears again.
So i gather, there is an error on the bluray inthe hd-dts track
But.....: playing the Blu-Ray directly from BDDVD or from the ISO with PowerDVD 8 everything wents fine! So, maybe the error is in eac3to???

Thanks!

You have to register Nero filters manually.
You can use Radlight Filter Manager for this purpose.
And if you want eac3to to use Nero filters, you have to put this option at the end of the line: -nero

(BTW, if you don't re-encode but just simply extract the audio (without changing it), decoders will not be used.)

You should first ask eac3to to post a track listing (e.g. "eac3to movieFolder 1)") and then simply fetch the track index from that list. E.g. if the list shows "2: TrueHD, ..." and "3: TrueHD, ...", you can use "eac3to movieFolder 1) 3: whatever" to select the 2nd TrueHD track.

The language is shown only if the full Blu-Ray folder and file structure is still intact. The language information is stored in the CLIPINF folder.

It doesn't work because it doesn't begin correctly. If it's an M2TS file, the 5th byte must be a 0x47. If it's a TS file, the first byte must be a 0x47. So you can use a hexeditor, search for the first 0x47 byte and remove the first few bytes of the file, until the fifth (or first) byte is 0x47. If that doesn't work, just repeat the process another 2-3 times. At some time eac3to will properly detect and handle the file.

Thanks. I'll forward this to the libav E-AC3 decoder maintainer.

Is this with eac3to v2.74? Which country is this Blu-Ray from?

I wonder why people continue to ask questions about tsMuxeR/TsRemux problems in this thread? This is the eac3to thread! If tsMuxeR or TsRemux don't work correctly then you should ask in the tsMuxeR/TsRemux threads for help.
