eac3to - audio conversion tool

[Sparktank]

FLAC library is replacable, in case of updates.

It's just limited to whoever compiles it out there.
RareWares will use ICL over GCC.

You have to scour the HydrodgenAudio forum for different builds.

OpenCL would vary too much from person to person to make it a default.
I've always used FLACCL as an external encoder after using eac3to. Doing other things with the audio first, so never piped directly to FLACCL.
In other instances, it wasn't time critical to wait for ICL FLAC to do its work.

My only options would be:
ICL FLAC
Intel FLACCL
NVidia FLACCL

anybody help me. When I demux atmos on windows 10 pro to mono wavs. I get error. I installed avisynth 2.6, arsoft decoder 1.4, eac3to 3.31, Klite codec. Tks. But when demux to ths+ac3 and thd. It's ok.

Is not related with AviSynth, Arsoft or other codec.
And you have the last eac3to version.

- Try to work with the extracted .thd file:

eac3to extracted.thd mono.wavs

If you have the same error "restart header sync incorrect" maybe is a corrupt file or a bug in libav decoder.

- You can also try with other decoder like:

ffmpeg extracted.thd output.w64

Or load the extracted.thd in MeGUI Audio Input and select Flac like Encoder settings, config -> Preferred decoder LWLibavAudioSource.

Is there a command/option to show all tracks on a disc not just the longer ones?

I am trying to load tracks that are only 5 minutes in length and they are not detected. I also require to find them from a disc not a mpls or m2ts.

eac3to v3.31

Try other decoder (ffmpeg, LWLibavAudioSource) or rerip the BD.

Hello,

i have a problem extracting subtitles. Well it works all fine, but the last subtitle is always "[GERMAN]". How does that come? Tried that with more movies and its the same everywhere. So at the end of the movie i always see "[GERMAN]" on my screen. I tried to delete it with SubtitleEdit, but it seems like i cant save it as .sup again. i dont want .srt. And if i export to .sup, it removes the shadow behind my font.

What i used to extract the Stream:

eac3to and HdBrStreamExtractor.

Hope you can help.

Here is a Screen of it: http://fs5.directupload.net/images/160323/vxjnmfv5.png

[r0lZ]

Use BDSup2Sub (Edit frame -> Exclude from export).

That is normal, the company which wrote these subtitles put that in. Every company adds their own endwords. Some write also "Untertitel von Ute Schmidt", or simple "Untertitel: Visiontext". It is not an errror or fault from eac3to. You have to delete these lines by hand.

If your eac3to version is less than 3.30 update to v3.31

[Overdrive80]

@Tebasuna51, the version of eac3to when I get that message was current version.

[tebasuna51]

This problem occurs before v3.30 when eac3to try to close the w64 file to write the correct header, but I don't know for what occurs with v3.31.
I can't reproduce the problem with the same command line.

Each block of PCM 2.0 24 bits must be 6 bytes, if ffmpeg only receive 4 there are 2 bytes missing at least.

[lvqcl]

Each block of PCM 2.0 24 bits must be 6 bytes, if ffmpeg only receive 4 there are 2 bytes missing at least.

Maybe eac3to writes padding bytes to the end of audio data?

From .w64 spec pdf: "All chunks are byte-aligned on 8-byte boundaries"

[asarian]

Just did a clean install of windows 10:

eac3to (v3.31) is up to date
Nero Audio Decoder (Nero 6 or older) doesn't seem to be installed
http://www.nero.com/eng/store-blu-ray.html
CAUTION: You need Nero 7. Nero 8 won't work with eac3to.

However, when I try to demux my DTS-MA audio, I get:

a03 Extracting audio track number 3...
a03 Decoding with libDcaDec DTS Decoder...
a03 libDcaDec reported the warning "XLL output not lossless".
a03 Mixing surround channels...

I dont want the libDcaDec DTS Decoder, though, but my Arcsoft one (used to work on Win 7 just fine); and eac3to, with the registered Arcsoft dll, is in the path. Did I miss a step somewhere?! Thanks.

[Boulder]

You have to specify -arcsoft in the command line. LibDcaDec is used by default and it is installed along with eac3to.

[Sparktank]

a03 libDcaDec reported the warning "XLL output not lossless"

it that's the only concern, dts decoding was like that before with earlier implementation of dcadec.
Just silently.

Arcsoft, too, iirc from earlier posts.
All just silent warnings.

dcadec is nice. you only need one version for most formats.
(minus express)

with Arcsoft, when it comes to "strange setup", it's a gambler's game on which version works on what source.

Thx. :) Guess I can just keep using libDcaDec then. Indeed, the occasional 'strange setup' and low volume issues that came with the Arcsoft decoder are something I could do without.

[bmcelvan]

Arcsoft is necessary for DTS-Express only, BTW remain like a option for users than prefer it.


Don't worry about that. Maybe are frames than not need lossless subframes (XLL), for instance silent frames.


Only when DTS-MA is "strange setup" ArcSoft remix the output channels forcing to have less volume than original. libDcaDec don't remix the channels.

Thanks for this reply, very helpful. MY interpretation of this means that eac3to v3.30 probably has that XLL error as well, it just didn't mention it? ...and with that said, I assume your advice is to ALWAYS USE THE MOST CURRENT VERSION OF EAC3TO? So currently 3.31.

Next question, just to verify, the current version 3.31 can properly decode TrueHD-Atmos to .wavs or convert to .flac? Iv'e been getting the "libav Lossless check failed" errors. From reading through the posts it appears that more than likely I have a corrupted file. Or are there still instances where eac3to won't decode Atmos properly?

In either case I should try ffmeg?

Thanks again

[Boulder]

Are those "lossless check failed" files from movies that are constructed of multiple m2ts files? I've noticed that it occurs at the beginning of each segment, but there is nothing audible there despite the error message.

[asarian]

In my case, it would seem so yes: the audio stream was from a collection of several .m2ts segments.

[bmcelvan]

Doesn't appear to be for me. I can't explain it, I just re-downloaded v3.31. Ripped via DVDfab to BDMV folder on my HDD the Bluray "Brave" and it simply won't extract the truehd file to .wavs or .flac or anything without giving the lossless check failed errors. Even at 17%, so that's a good chunk of the way thru the movie, not at the beginning.

Could this have anything to do with the TrueHD audio dropouts reported on a bunch of websites for Pixar titles like Monsters University, Brave, Total Recall (2011), etc. Apparently, bluray players needed to be set to LCPM output instead of bitstreaming to fix the problem?

[Snowknight26]

The lossless check failed errors are normal for Blu-rays that use seamless branching. eac3to has no problems with them as of 3.25, released over 3 years ago.

[bmcelvan]

The lossless check failed errors are normal for Blu-rays that use seamless branching. eac3to has no problems with them as of 3.25, released over 3 years ago.

Thanks for reply...two quick questions then.

Seamless branching means that if you look at the .mpls file it will have multiple m2ts files that it looks at? For example after eac3to has looked at a title you might see something like: 00800.mpls, 00001.m2ts+00005.m2ts+00670.m2ts, etc??

Second question: decoding/converting atmos is now not a problem for eac3to either, right? That was solved in version 3.28?

thx

[bmcelvan]

Quick question about this past conversation...every single one of the "lossless check failed" errors only represents 1 byte?

Also, could it ever mess up the alignment of the audio track...I mean shorten it or lengthen it slightly, or would it simply be just added (or deleted) sounds but not affect it's length?

Done, but still getting errors. This track is definitely skunked.

Most likely because the source uses seamless branching. Only 6 bytes of probably over 3GB is corrupt. You won't even hear it.

Dolby Atmos metadata should reliably be ignored in current versions.

[tebasuna51]

Yes.

Thanks for that thread...very helpful inunderstanding what is happening, thank you.

Is there a simple answer to my earlier question about what each lossless check failed means in terms of added or reduced audio track duration? Or is every occurrence potentially different ? (and saying something like "each error adds 1/32 seconds time to the track" just doesn't make sense)

[tebasuna51]

Is there a simple answer to my earlier question about what each lossless check failed means in terms of added or reduced audio track duration?

A frame bad initialized can produce glitches like here (http://forum.doom9.org/showthread.php?p=1587184#post1587184) but don't change duration.

[r4dius]

Could you show info about "forced" subtitles (at leat with mkv files) ?

And btw thanks for one of the best ripping tools ever :)

[Stereodude]

Are those "lossless check failed" files from movies that are constructed of multiple m2ts files?
In that case it has to deal with floating point math and integer math so it's not exactly lossless.

"The main problem is that the core decoder converts integer coefficients read from the bitstream to floats just after reading them (along with dequantization). All other steps of the audio reconstruction are done with floats and the output can not be the bitexact reproduction of the input so it is not lossless."

From http://sasshkas.blogspot.com/2015/11/dts-decoder-why-xll-streams-are-not.html

[bmcelvan]

A frame bad initialized can produce glitches like here (http://forum.doom9.org/showthread.php?p=1587184#post1587184) but don't change duration.

Okay, so occasionally there may be some sort of (glitch) noise that you could hear (but probably can't hear it) but it won't affect the audio track aligning properly with the rest of the movie (from that glitch point on)?

[bmcelvan]

I just want to make sure I'm not the only one, I've encoded audio for 10 movies in the last 2 weeks or so and with v331 and DTS-HD MA tracks I get the error (a03 libDcaDec reported the warning "XLL output not lossless") EVERY SINGLE TIME!!!

Is everyone else getting this error every single time?

I understand people are telling me "don't worry about" but if it isn't something to worry about why does it pop up every time and/or why hasn't it been hidden?

For all those same movies, as stated before, v330 it doesn't appear.

Lastly, what are the reasons to use 331 over 330?

thx

[Sparktank]

why does it pop up every time and/or why hasn't it been hidden?

It was hidden in the versions that don't show it.
v330 has the same warnings but it just doesn't tell you about it.

Reasons to use 331 over 330?
Some of the udpates might be relevant in certain circumstanes.
* libDcaDec: updated to latest build
* libDcaDec: decoding only aborts on critical issues now
* libDcaDec: now reports warnings if something isn't 100% perfect
* libDcaDec: proper handling of clipped files (2nd pass etc)
* libDcaDec: proper handling of tracks that switch bitdepth 16 <-> 24
* fixed: TrueHD decoding -> AC3 encoding didn't work properly

As tebasuna51 mentioned before...
Don't worry about that. Maybe are frames than not need lossless subframes (XLL), for instance silent frames.

Arcsoft probably gets the same errors but doesn't report them, either.
I would still use updated/DcaDec regardless of warnings:
Arcsoft is necessary for DTS-Express only, BTW remain like a option for users than prefer it.

Only when DTS-MA is "strange setup" ArcSoft remix the output channels forcing to have less volume than original. libDcaDec don't remix the channels.

TSMuxer can de-multiplex your file. Don't know why eac3to can't identify the PCM track.

[ron spencer]

Interesting that if I remux the MTS files to M2TS via tsmuxer the EAC3to will be ok with them.

[LigH]

Then the reason might be an unusual audio track ID? That may require in-depth analysis of the TS headers.

[ron spencer]

Here is the M2TS file mediainfo

Seems like a mystery...

[ron spencer]

It is the same at the MTS file that is causing the error...see here. Should I be looking elsewhere for the headers?
