You need convert the DTS-HDMA to special lpcm format accepted by tsmuxer, use Pcm2Tsmu v1.2 with eac3to.

Thanks.

Do I designate RAW or PCM or LPCM as the output format in eac3to? Literally, what should I type in?

You have samples in the post linked:

eac3to MA_7.1_16bit.dts stdout.pcm | Pcm2Tsmu - output7.1_16bit.pcm -c 8 -i 16

Is it the RAW option?

Try doing

3: "C:\The Interpreter (2005).h264"

instead, and then muxing that to MKV with mkvmerge GUI (included in MKVtoolnix).

@Madshi
We can't demux files to another location like - eac3to.exe C:\00001.m2ts D:\ -demux or eac3to.exe C:\00001.m2ts -demux D:\

& can you tell me how to get back exact raw VC1 stream after merging into mkv. Actually i accidently deleted backup file. Now i want exact raw VC1 stream demuxed from mkv.

[Kurtnoise]

@Madshi : feature request >> add an option to demux m2ts/ts and/or evo files by chapters... That could be great.

[xsictransitx]

@madshi

It would be great if using the bluray (or HDDVD) to mkv muxing ability would also mux an or all audio tracks into the mkv with the video. Is this already possible and I just am missing how?

I want to use eac3to l:\ j:\out.mkv
and have audio in that output as well as the video track, but I do not see a way to do it.

Thanks for creating the best HD audio conversion tool available! Keep it up.

This method given by madshi earlier is even easier to DO than he is able to DESCRIBE it here!

(1) Extend the search path to include eac3to's folder. In Windows XP you can do that by:

right click on My Computer -> "extended" tab -> "environment variables" button

In the first list double click on "PATH". Then add ";c:\program files\eac3to" (replace that path with the one you're using on your PC) to the list of paths. This change will make sure that you can always directly type "eac3to" in the command line, no matter in which folder you are. Windows will then automatically find eac3to.exe for you. Very comfortable. You may need to log off/on to make the "PATH" change active.

(2) In the command line go to the folder where you want to have the files demuxed to. E.g. if you want to have the movie "c:\fresh rips\some HD DVD movie" demuxed to "c:\demuxed\some HD DVD movie", you should in the command line go to "c:\demuxed\some HD DVD movie". I mean the command line window should look like this "c:\demuxed\some HD DVD movie> _".

(3) Now type:

eac3to "c:\fresh rips\some HD DVD movie" -demux

This will demux everything to "c:\demuxed\some HD DVD movie".

This is not possible yet. Maybe it will be supported in the future, as madshi said somwhere above.
However, you should be able to do everything in one go already. Just use the eac3toandmore GUI.

When you right click on my computer you get a drop down menu. There are no tabs let alone one called "extended". I don't understand these instructions. If you select any of the options you see on the drop down menu there is still no extended tab anywhere.

Right Click on My Computer -> Properties -> Environment Variables

See if that sequence works for you.

On my XP PC, right-My Computer -> Properties -> get System Properties, click on Advanced tab, at bottom is Environment Variables. Once there find the Path entry and click Edit, then add

;C:\Program Files\eac3to

Don't forget the semicolon delimiter and make sure that you use YOUR path to eac3to.

Once this is done you go to a command prompt and the cd to the drive letter & directory you want your file to END UP in. For me, I always go to D: and process files from E: or vice-versa, to get a speed advantage from using different hard drives.

Yeah, mine was probably already on sitting on the advanced tab.

On my Vista Premium it's:
Right Click Computer -> Advanced system settings -> Advanced Tab -> Environment Variables

Hi madshi,

Do you mind to tell what source filter you are using for ac3 core files?

I've never found any source filter which fits to those files in my graph trials.

Hey, has anyone successfully used eac3to with the region a BR of Mr & Mrs Smith?

The reason I ask is that when I use eac3to to look at the BR directory, and then choose option 1 (the only option) I get this message...

Is is possible to make a "remux" from a BD ? I want take the mainmovie and sound, subs to output to a new m2ts file ??

If this works , then is the only tool I need :-) :-) :-)

In both files it shown 27694 frames. Hope you're getting me, what i want to say.

Is there a question hidden in your post somewhere? Or a request?

DTS-HR samples with some special properties (e.g. 96khz or 6.1 or 7.1) are still welcome, but I don't need more straight 5.1 48khz samples. Thanks!

Doesn't Cyberlink still downconvert everything to 16bit?

Thanks, I'll check that out.

-----------------------------------------------------------------^C

Then at about 80%, the process hangs, CPU goes back to 0%. I waited for an hour, but no progress. After I press <ctrl-c>, there is an output file which seems to play OK, but seek doesn't work. From the size of the file judged, it is not complete.

When I just extract the track & convert to flac (so keep 24/96), eac3to works correctly and the output file plays OK.

However, converting this 24/96 flac track to 16/48 with eac3to gives the same result: hangs at the same position.

Down convert to 16/96 works, only when I resample to 48k it hangs.

I cannot use r8brain directly for the conversion as r8brain doesn't support flac and seems to have problems with wave files larger then 2GB. So I'm kind of stuck here.

Tried in Windows Vista 32bit Home Premium SP1 USA on 2 different computers. eac3to version tried both 2.55 and 2.56

Anything I can try?

Hmmmmm... That sounds bad. Can you please in that situation where eac3to hangs run this tool:

http://madshi.net/madTraceProcess.zip

That will output a report of where eac3to is stuck. Can you please upload that report somewhere? Or you can also mail it to dear (at) madshi (dot) net. Thanks!

Ouch, that's really bad. But there's nothing I can do about it right now. As was already suggested you could demux the h264 track and mux it to MKV with mkvmerge. Unfortunately sometimes mkvmerge produces bad results when doing h264 muxing. But maybe you're in luck with this one...

Yeah, that would be nice. Unfortunately it's not as easy as it might seem. The problem is that I'd probably have to recalculate the audio delay for every chapter. And that doesn't really fit into the current eac3to code structure/logic. I'll put this on my to do list, but I don't think it will be implemented anytime soon...

You mean for demuxed AC3 files? The orbitlee source filter should work. Personally, I'm using my own, though...

Could you please check whether the problem still occurs if you produce a sample with the first 50MB of the file? If the problem still occurs, could you please upload that 50MB sample somewhere for me to check? Thanks!

eac3to doesn't output m2ts. It only supports m2ts as an input format. Check out TsRemux and TsMuxer. I think both of them do what you're looking for.

I have a question about this. If you want to mux a Blu-Ray structure with tsMuxer, then it requires for the AC3 core to remain intact inside the TrueHD file.
When I want to remove dialogue normalisation with your wonderfull application, then I am 'forced' to detach the TrueHD stream from the core.

Is there maybe an undocumented option to still remove the dialogue normalisation, but maintain the full track? If not, maybe this can be a future request for your excellent application.

Tnanks for the response; do you mean "dts core" or are there any standalone orbitlee DX Source filter?

EDIT: correction; dtscore only accepts dts and wav files; so there should be a standalone filter
