Hi,I been trying to get eac3to to work for me but for the life of me I can not!:mad: A guy said to use eac3to find the play list along with the mlp audio tracks and then just bring the ones you choose up with TsmuxeR.I have the 2.46 version of eac3to,the command line and the gui.He said to use the command line version to get what I want.I do not want to re encode anything,I just want to cut it down in size,like get rid of extras and all the other lang and stuff.I have eat up all most 1.5 tbs of Hdd space.The command line version is in my program files,thats where I un zipped it to.What would be the exact command to use to get it to read the play list from a Blu-Ray disk from the drive or the folder.I have Dejau on my "L" hard drive,blu-ray ripped with AnydvdHD.I have other iso's also on same drive.I do not know how to write commands.Can you help me?
Well, you'll have a hard time using the command line tool if you don't know how to use the command line generally. I'd suggest trying the GUI here:

I did two times dts core extraction from BD Kingdom Of Heaven and no success.

Best bet is to rip it again. Players are generally more forgiving. I've got a couple of discs that won't rip but will play.

I don't think a sample will help. This looks like a real damage in the source file. A missing sync byte is a very simple check. There's not really a big chance that eac3to has a bug in this situation.

Is this a one part movie? Or does the movie consist of multiple m2ts files? In the latter case check the file size of all m2ts parts. Are they all divisible by 192?

Got another one of those sync byte errors (would test with an earlier version of eac3to but I don't have them) one a one part film. Reripped it, still the same thing. Used xport to demux the DTS MA, then ran it through eac3to:

W:\Encoding Tools\eac3to>eac3to.exe disc1.dtshd disc1.flac

This track is not clean. Processing aborted.
Please clean the track with delaycut and then retry eac3to.
Aborted at file position 181780480.

So lets see.. since delaycut doesn't handle DTS variants apart from DTS itself, I would say that that line should be removed/altered. Either that or some kind of -skipErrors switch. :p

You can use delaycut to spot the position and how big the problem is. If it's 1-2 frames you can use a hex editor to edit (correct) the dts frame header, so it can be processed by eac3to. PM me here or at HD... if you want any kind of help.

What I'm saying is, delaycut doesn't handle DTS-HD MA, so eac3to's suggestion to use delaycut on that track is pointless.

Just use eac3to and extract only the chapters file. Copy and paste won't work, not from the .xpl file.

I wanted to create a 640kb/s AC3 file from a TrueHD track on Bluray. Here is my log file:

It seems eac3to has extracted the core 448kbit track instead of encoding a new one from the lossless data, and I can confirm the the output is 448kbit..

Is there anyway to go straight from Bluray TrueHD to 640kbit AC3? Perhaps the -core switch could be used to specify that the core AC3 track is required.

Cheers, Beastie.

It must be the 1st blu-ray with TrueHD/AC3 stream that the AC3 part isn't 640 kbps! :D Which movie is it?

Since you need a 640 kbps one, try:

eac3to "H:\BDMV\STREAM\00011.m2ts" 4: "D:\HD_Working\REE.ac3" -640

and if that doesn't work, do it in 2 steps:

eac3to "H:\BDMV\STREAM\00011.m2ts" 4: "D:\HD_Working\REE.thd"

eac3to ree.thd ree.ac3

Resident Evil Extinction. I'm currently creating a 16bit wav file usind -down16, which I will then transcode to AC3. One thing I notice is that the output file is called REE.24bit.wav despite the output being forced to 16bit. Not a big deal I know, but I thought I would mention it.

Cheers, Beastie.

Edit: On completion, the file is simply called REE.wav anyway.

Why did you decode to wav and why did you reduce the bit depth? The command lines i suggested you will produce a better (since you 'll use the full 24 bit info from the TrueHD) and faster since you do Truehd decoding and encoding AC3 in 1 step.

I was toying with the idea of just keeping the wav and muxing that into my TS file. I decoded to wav to see what the resultant file size would be. I don't think the AC3 encoding process would retain 24bit (or even 20bit) information anyway, so I figured there would be no quality difference.

If it says the DTS track is invalid, it won't show up in the stream list, even if it is present.

It might be playing fine because you are converting the other audio tracks instead of the DTS track.

When I tried to do the second video on the disk I got a TON of overlap errors and the result, after the second pass, wouldn't play. <shrug> It's just the director's extras stuff and consisted of like 10 different files of wildly differing sizes.

I have a problem converting chcken little blu-ray to mkv. I get glitches in the 10 first seconds of the video. After that everything is fine.
Can you reproduce the glitches with the sample? I'm asking because I can't. The sample you provided converts to MKV for me just fine - and plays perfectly with both CoreAVC and Cyberlink (Haali Media Splitter).

Yes, i can reproduced the problem with the sample, but it plays fine with Cyberlink decoder (which i didn't test :( ). So, it's a decoder issue. I'll post to ffdshow thread, but i think they can't do anything (since mpc's internal decoder behaves the same, which means it's an ffmpeg problem).

Two questions:

(1) Have you tested CoreAVC? Testing with Cyberlink is not a proof yet, since there have been cases where Cyberlink gracefully played bad MKV muxes (created by mkvtoolnix) while CoreAVC showed artifacts. So a good test is always to try both Cyberlink and CoreAVC. If both show a perfect artifact free image, usually the mux should be fine.
(2) Does the problem also occur with the original m2ts file? If yes, that would be the proof that the decoder is at fault and not the MKV remux.

1. CoreAVC decoded the sample fine.

I've read that I can decode TrueHD audio if I have Nero 7 and the HD/ Blu Ray plugin, but as far as I know, Nero 7 isn't sold any more.

I also have the movie on regular DVD, which has the normal ac3 track, but the problem is that the HD video and the DVD-ripped audio don't play in sync together.

I'm not sure of what I can do to get these files to play together in sync, so I would be really grateful for any help on how I can get around this problem (regardless of if it's TrueHD, ac3 or not).

Thanks. Any help is really appreciated! :)

Thanks for the National Treasure 2 sample. I can confirm that there is a DTS track in the movie - it's the audio track of the PiP content. And that DTS track is really strange. It doesn't contain any conventional DTS elements. I mean there's no core. There are only DTS-HD packets in the stream. eac3to doesn't know what to do with that kind of track, that's why you see the complaint in the log. You don't need to worry, this is really only the PiP audio.

Have you guys noticed that this is one of the first Blu-Rays with a *TRUE* PiP video/audio stream in it? As you can see in the eac3to log, a secondary h264 video stream is detected. That's the first Blu-Ray I've seen with a 2ndary video track!

What do you mean by "true"? The Golden Compass has a second video track which is PiP. Is it the same thing?

madshi

23rd May 2008, 13:08

Never heard of "DTS-Express" yet. What I can say is that the data packages in the PiP audio stream have the same "signature" (first for bytes) for each audio block as the additional DTS-HD audio packages in a DTS-HD stream have. Is there a DTS-Express specification available somewhere?

What do you mean by "true"? The Golden Compass has a second video track which is PiP. Is it the same thing?
Yeah, that should be the same. It seems that PiP is beginning to be spread for Blu-Ray now.

Have you tried using eac3to on the source .evos instead of a rebuilt one? You might try that and then report any error you get (if any).

Thanks Yraen. By 'the source .evos', do you mean the streams ripped off the HD DVD (by AnyDVD) or do you mean I should copy the contents of the disc on to the hard disk?

Also, the original is actually two files -- that's why I rebuilt it instead of using eac3to directly on the file. Are there any extra commands I need to tell eac3 to move on to the second file automatically?

Thanks again for your help!:)

Is there .mpls support planned or I am doing something wrong?

mpls support is there is is tranparrent. Point eac3to to the folder containing all the BluRay files and it will list all the titles, with info showing which m2ts files are joined, and the streams they contain.

Using eac3to_and_more_gui makes it easy using the 'Add Folder' button.

Cheers, Beastie.

I usually use Eac3to_and_More_GUI, I was just trying to add the MPLS file by itself. I'll give your way a try...thanks :)
