Select "all files" and load your eac3 file (extension must be .ddp or .eac3)

inflated flac files

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?

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.

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.

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.

Probably your source files are damaged. Please try to rerip them.

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 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?

The best way to repair this error is to rerip the movie.

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.

Ok, sounds good. How about:

(1) eac3to - development (bugs and improvements)
(2) eac3to - help (how to use etc)

?

Where would these new threads be? Audio sub-forum isn't ok, i think...

Do you think that New and alternative a/v containers sub forum is the proper one?

Remuxed the file without problems to ts with tsmuxer. Remuxing the ts to mkv with eac3to worked fine as well. Checking some random points it seems at first sight that the mkv is okay.

Might your error checking be too harsh? Or am I potentially creating trouble using this path?

I tried to convert blu-ray Chicago to mkv and got an

Tried the -seektoIFrames option, but that resulted in the same error.

I thought this option was introduced for these kind op errors or am I mistaken?

I made a small sample but eac3to complains that it cannot detect the format of the source file. Might this sample nevertheless be of help?

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.

Sound good?

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.

This blu-ray tracklist contains a small error. The third track is DTS 2t channels.

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:
Code:
eac3to "K:\Chicago [Blu-ray]\Chicago_1.m2ts"+"K:\Chicago [Blu-ray]\Chicago_2.m2ts" 1:d:\Chicago.mkv -seektoIFrames 2:d:\Chicago.ac3

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.

I think that the first page of this thread will be good for the introduction for the help thread so I'll just leave it here. When My list is done I'll let you know and you can start the new development thread with an introduction post that contains what you see fit.

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 .

Since main purpose of eac3to is to convert HD DVDs and Blu-ray Discs to matroska format, i believe it would better fit there. But whatever you/the mods decide doesn't really make any difference.

DTS-MA to DTS

Die Hard 2

eac3to 00001.m2ts 2: diehard2.dts

M2TS, 1 video track, 5 audio tracks, 2:03:21
1: h264/AVC, 1080p24 /1.001 (16:9)
2: DTS Master Audio, English, 5.1 channels, 24 bits, 48khz, -9ms

encoded to dts with SurCode, but cannot mux into mkv. I got timing errors, no dts header found, bytes discarded, yada yada yada.

So I'm going the manual route:

eac3to 00001.m2ts 2: diehard2.wavs

QUESTION:
Do I need to specify the -9ms delay?

REQUEST:
A better set of instructions for use.

Thanks for the great program.

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
