You can demux the audiotrack with evodemux or xport. And clean it with delaycut.

I've been re-encoding some DTS-HD flacs that have been obtained from both blu-ray and HD-DVD with recent versions of eac3to. The original files are the ones that are created directly by eac3to and then them I re-encoded with 'flac 1.2.0a -8' using Foobar2000. The resulting files are usually way smaller (3.7GB -> 1.7GB and 2.0GB -> 1.5GB) while the bitrate and sample depth remains (about) the same. Why does eac3to creates these hugely inflated flac files?

Snowknight26

Thats probably why. Run both flacs through eac3to and see if they're the same depth or whatever else might have changed.

Thats probably why. Run both flacs through eac3to and see if they're the same depth or whatever else might have changed.

Sorry, I should have been more careful: The bitrate remains about the same (eg 5000 kbps -> 4990 kpbs, probably due to going from 'flac -5' to 'flac -8'), the sample depth remains 24 bit.

is it possible to extract a core from a DD+ track?
Blu-Ray DD+ tracks have a DD core. HD DVD DD+ tracks do not. Blu-Ray DD+ tracks are extremely rare, though. So generally it's safe to say that DD+ tracks do not have a core.

which aften-commandlines are used internally in eac3to for 5.1-AC3-encoding for the different audiostream-types.
None at all. I'm not using aften.exe, I'm using libaften.dll. So no command line, instead I'm calling exported functions from the dll.

Thanks for everyone's help so far, but I'm still having problems decoding the audio. Here's the log.

[libav] No restart header present in substream 0.
[a04] The libav decoder reported an error while decoding.
Aborted at file position 12588386304.
Probably your source files are damaged. Please try to rerip them.

I suggest we split the eac3to thread into two separate threads; one for development and related topics and one for general questions. This thread is getting enormous and finding answers by using search is surely difficult if not like trying to find a needle in a hay stack.
If we started now we could easily do that. But how do you want to split this existing thread into two? Who would volunteer to walk through those hundreds of pages and decide which post belongs into which thread?

I've got one .ddp track that won't decode to DTS. EAC3TO gives error (this track is not clean...). I've tried DelayCut (selected fix crc errors), I always end up with file that is only about 100 Mb, original is about 1 Gb. Am I doing something wrong or is this file unrepairable?
I suspect that it's not a DD+ track but a DD track. Where did you get the track from? What does eac3to report about this track?

Then the Help should read simply "supports all legal AC3 bitrates"!!! :p
I've changed it to "use e.g. "192", "448" or "640" kbit/s for AC3 encoding" now.

Got a missing sync byte error in Finding Neverland. What's does that mean? And is there any way to repair or avoid this error?
The best way to repair this error is to rerip the movie.

Select "all files" and load your eac3 file (extension must be .ddp or .eac3)
delaycut supports drag&drop. It's oh so much easier than walking through all those file open dialogs... ;)

My best guess is that in the Foobar2000 reencoded files the lowest 8 significant bits have been zeroed out. But I don't know for sure. You can do try this:

"eac3to foobar.flac eac3to.flac"

Does the file size go back from 1.7GB to 3.7GB this way? If yes, then I have to check out what's happening. If the file size stays at 1.7GB then Foobar2000 has manipulated the audio data while reencoding it. It would not be a big surprise! Because many of the open source flac decoders only support 16bit decoding. That means if you decode with Foobar2000 you probably lose anything over 16bit. Just guessing here, though...

Yes it's a daunting task. We have two options here as I see it: One, we could sift through the several hundred pages in this thread and try to divide them, and two, we could just start a new thread and direct all general questions to it. If we can come up with guidelines for what material would belong to which category I will re read through the entire thread and make a list for the moderators.

Sounds good. I think I should be able to do that. Problems will appear for the splitting though when bugs/improvements arise from questions. But I think I can handle it. I'll get on this tonight. The help thread will probably turn out to be a good 80 - 90 % of this current thread. Because of this I think the list I will make will consist of only posts to be moved to the new help thread. I will start the thread with a post and ask the moderators to append it with all of the posts in my list. This thread will then be kept as the development thread. Maybe the title will need to be modified to tell as much.

Good point. This is along the same line as the topic which was running in this thread a while ago about changing the name of eac3to since it's not just an audio tool any more. The topic is already here so maybe it should stay. I think this is a call that should be made by a moderator. Also if the eac3to threads are moved then the GUI thread will need to be moved too.

Each track number (1:, 2:, etc) gets it's own switches. Putting the -seektoIframes switch at the end is applied to track number 2, which is an audio track.

The correct command is:

That's a tough decision. eac3to does so many different things. Audio processing is still a very big part of eac3to. To be honest, I don't really know into which sub-forum it really belongs. Maybe we should let the mods decide?

I'd suggest to do it the other way round to save the mods some work. Moving 10 - 20% of the posts is much less work than moving 80 - 90% of the posts!

Furthermore I think it would be helpful if both threads had a good introduction post like this thread currently has. So maybe I should start a new thread for development?

Nope. A missing sync byte is a very easy and reliable check. If the sync byte is missing, something is really wrong.

Make sure your delaycut version is 1.3.0.0. If you get a lot of errors, then your track might be severely damaged.

Where did you get that ddp track and how did you demux it? Re-ripping the disc might solve the problem.

Got the same result every time i ripped that disc. Luckily you mentioned to someone to make sure that dd+ is named .ddp or .eac3, that solved my problem with delaycut :).

nautilus7

28th May 2008, 23:41

EVERY dts-hd audio track contains a simple dts core @ 1536 kbps. If that is the bitrate you want, don't encode with surcode. Just use -core switch to extract the core.

If you let eac3to do either demuxing or decoding of any track ,you'll see a mesage saying "applying delay". So the answer is no, you don't need to do anything regarding the delay.

Suggested command: eac3to 00001.m2ts 2: audio.dts -core

Hello

I am trying to get a DPL2 downmix from a VOB DTS track. For example I have DTS encoded music DVD that has individual music tracks (as chapters?). When I use the demux option it just pulls out one large dts track which when downmixed gives me one large file. Is there a way to extract the audio track based on the video indexes or am I missing something easy?

Great tool, can't wait to get into the lossless HD stff...

Disney's "The Game Plan" has 92 streams, 00000.m2ts through 00091.m2ts.

Running the command eac3to works, but when I try and add the files, either 2) or by listing the all the files with '+' between them (used a spreadsheet), the program gets stuck. Does nothing.

Perhaps 92 is more pieces than eac3to can handle?

EDIT - It works after about 5 minutes. Had to get a cup of coffee, then I saw the results. Yeah!

SoleBastard

29th May 2008, 19:51

My best guess is that in the Foobar2000 reencoded files the lowest 8 significant bits have been zeroed out. But I don't know for sure. You can do try this:

"eac3to foobar.flac eac3to.flac"

Does the file size go back from 1.7GB to 3.7GB this way? If yes, then I have to check out what's happening. If the file size stays at 1.7GB then Foobar2000 has manipulated the audio data while reencoding it. It would not be a big surprise! Because many of the open source flac decoders only support 16bit decoding. That means if you decode with Foobar2000 you probably lose anything over 16bit. Just guessing here, though...

Well, if I do your trick the resulting file is exactly the same size. So no new inflating back from 1.7GB to 3.7GB. However, I don't think Foobar2000 has any problem with 24bit decoding. It explicitly supports 16, 24 and even 32bit decoding and the converter includes the option to 'keep lossless sources at original bit depth'.

Moreover, as I already mentioned, the bitrate remained about the same at ~5000kbps, only the filesize shrunk dramatically. 5000kbps is a pretty normal bitrate for a flac encoded 24bit 48kHz 5.1 track that contains music (not for movie tracks).

Is there anything else I can do to make sense of it all?

Is there a way to extract the audio track based on the video indexes or am I missing something easy?
Currently eac3to's VOB/EVO support is limited to work with movies. It doesn't really work well if you want to extract chapter wise. My suggestion would be to extract the DTS files with another tool (e.g. DVD Decrypter works very well for me) and then convert the extracted DTS files to DPL2 with eac3to.

Disney's "The Game Plan" has 92 streams, 00000.m2ts through 00091.m2ts.
And they are all for the movie? Ouch!!

Running the command eac3to works, but when I try and add the files, either 2) or by listing the all the files with '+' between them (used a spreadsheet), the program gets stuck. Does nothing.

Perhaps 92 is more pieces than eac3to can handle?

EDIT - It works after about 5 minutes. Had to get a cup of coffee, then I saw the results. Yeah!
eac3to has to open every file and read the first 30MB and last 30MB (or something like that). That can take a while. Maybe I should add a progress bar for this initial parsing, too...

So was the end result just fine? I imagine you must have had a pretty long list of audio overlaps!!

Well, if I do your trick the resulting file is exactly the same size. So no new inflating back from 1.7GB to 3.7GB.
In that case it is as good as proven that Foobar has modified the data!

However, I don't think Foobar2000 has any problem with 24bit decoding. It explicitly supports 16, 24 and even 32bit decoding and the converter includes the option to 'keep lossless sources at original bit depth'.
Can't say anything about that. But I can say that eac3to will end up with exactly the same FLAC size if you feed it the same data twice. So if the original FLAC file created by eac3to was 3.7GB while the FLAC file created from the Foobar reencoding was only 1.7GB then there's only one possible explanation: Foobar *must* have changed that data! There's no doubt about that.

Moreover, as I already mentioned, the bitrate remained about the same at ~5000kbps, only the filesize shrunk dramatically. 5000kbps is a pretty normal bitrate for a flac encoded 24bit 48kHz 5.1 track that contains music (not for movie tracks).
That bitrate number has no meaning whatsoever. I'm not even sure what number 5000kbps is supposed to be. I mean a 24bit 48kHz 5.1 PCM track has a bitrate of 6912kbps. So if the bitrate is meant to describe the decoded PCM track it's wrong. And if it's supposed to describe the FLAC bitstream then it's wrong, too, cause there's no way that a 3.7GB has nearly the same bitstream bitrate compared to a 1.7GB track of the same runtime. If you think about it, that just doesn't make any sense...

Should posts that are questions but pertain to the workings of eac3to (such as how certain decoders work) be included in the development thread? If not the development thread is going to be very small.

EDIT: I'm beginning to think that this project might not be possible to implement because it would probably entail the mods actually having to break up a lot of posts into separate posts for the separate threads .

Should posts that are questions but pertain to the workings of eac3to (such as how certain decoders work) be included in the development thread? If not the development thread is going to be very small.
I think (valid) bug reports should be part of the development thread. Questions about how eac3to works rather not cause they have no effect whatsoever on the development of eac3to.

EDIT: I'm beginning to think that this project might not be possible to implement because it would probably entail the mods actually having to break up a lot of posts into separate posts for the separate threads .
It's problematic. If all else fails you could put all posts which are full or part development into the development thread and the rest into the other thread. The development thread would probably still be smaller. The biggest problem might be my style of replying. I'm often replying in one big post to 10 people at once. Maybe in such a case such a monster reply should be copied to both threads? Don't know if that is even possible...

how about supporting wave 64 files produced by Sony software?
Don't know how complicated they are. Do you have a sample? Do you also have information about the file format?

Is slowing down an AC3 stream supposed to make it 50% bigger?
The file size of an AC3 stream only depends on 2 things:

(1) runtime
(2) bitrate

Slowing down an AC3 stream increases the runtime, but only very slightly. So file size increases also very slightly. If you have a 50% size increase then obviously the bitrate you used for the new encoding is about twice as high as the bitrate of the original file. eac3to always uses 640kbps for new 5.1 encodings. If you want to save space you can force eac3to to use a lower bitrate - of course that goes on the cost of quality.

eac3to always uses 640kbps for new 5.1 encodings.

As well as 2.0?

While I'm here, is there any possibility of adding some kind of error skipping switch? Would be very welcome for those that try to reencode badly authored streams.

Since main purpose of eac3to is to convert HD DVDs and Blu-ray Discs to matroska format,

It is? I thought it was primarily used to convert DTS/True HD - > AC3. That's what I use it for anyway.

By accident I selected the wrong stream today, which was a VC-1 video stream, and eac3to said it couldn't recognize the video stream. Which is okay with me, as I use it for audio conversion only, but if it can't handle VC-1 stream, I guess I won't be using it for video then. :)

You can see the WriteHeader routine in Encoder.cs from last BeHappy source code (http://www.codeplex.com/BeHappy/SourceControl/ListDownloadableCommits.aspx), with support for wav, w64 and rf64 headers. Only the header change the audio data is the same.

EDIT: Docs:

I am talking for the present, not the past. First thing eac3to was able to do was to decode E-AC3 tracks (eac3to is called, isn't it?)

If you accidentally chose the VC-1 stream (instead of an audio one, let's say) then you did something wrong, not eac3to. Post the log and don't jump into conclusions like "eac3to can't handle vc-1". What all these people using eac3to with vc-1 streams would think of you?

Where might one purchase ("Sonic Cinemaster Audio Decoder 4.3" DirectShow filter). I have (Easy Media Creator 10) and it isn't part of that.

I think it is. At least I too have EMC10 and I have it. I cannot think of anywhere else it would have come from. How have you checked?

Yes, that's what the term "accidentally" implied. :) Just one of them occassions where I copy & pasted a line with eac3to in it that had the wrong stream number for the new file. No big deal.

Post the log and don't jump into conclusions like "eac3to can't handle vc-1". What all these people using eac3to with vc-1 streams would think of you?

They'd probably think I accidentally selected a wrong stream once, that it complained about not being able to handle that stream (likely because I added audio commands on the same line, which naturally don't apply to a vid stream); and that, since I wasn't gonna do video with eac3to anyway, that finding out the why of it had not my highest priority. :)

But seriously, I didn't mean to offend the eac3 folks: it's a heck of a good program, even if you only use it for audio.
