eac3to - audio conversion tool

First, I appreciate all efforts here.

That said, as I mentioned above, G has tons of room (over 2.5 TB free)

I can't really change the input format, the input format is the movie.

I can try to adjust the output format, and report back what happens. I'm not sure how it will help me if that works though.

Try a different one if you can.

Try to do each extraction separately to see if a certain one stalls eac3to's progress.

Is the drive you're outputting to a RAID? It could be Haali Media Splitter's gdsmux not liking the drive. I've had an issue where eac3to couldn't write more than ~2MB an MKV on one of my RAIDs. The only solution was to switch RAID controllers/recreate the array. Never figured out exactly what caused it but it might be worthwhile to investigate.

The drive is not RAID. So that's not the issue.

I'm running some additional tests, the hangs appears to be in the creation of the mkv file. It does not hang when just creating the .w64 file.

So I ran -test and noticed that, despite Haali being installed and recognized, it says MkvToolnix is not installed.

I never installed that tool in the past, is it actually needed?

[Snowknight26]

No, it's not used for MKV muxing.

Try remuxing the file with gdsmux (in your Haali Media Splitter directory). Chances are it won't work either, in which case it's not an eac3to issue.

You are correct. It did not. It got hung up in a very similiar manner.

Any suggestions as to a good forum to seek support for this issue?

Thanks,

[Snowknight26]

This one, but it's hopeless. I don't think Haali reads the forums anymore so don't expect it to ever be fixed. The only alternate is to output to a different drive.

Thank you for this tool. It is very useful.

I request a couple features, however.

1: A command parameter to demux a given file without demuxing the video. "-demux novideo"

2: The ability to output a plain-text list of all produced files from demux or mkv conversion. "-makelist"
Example list inside Movie1.txt:

video > c:\folder\movie1 - 2 - VC-1, 1080p24.vc1
audio > c:\folder\movie1 - 3 - DTS Master Audio, English, 5.1 channels, 24 bits, 48kHz.dtsma
subtitle > c:\folder\movie1 - 4 - Subtitle (PGS), English.sup
subtitle > c:\folder\movie1 - 5 - Subtitle (PGS), Spanish.sup
subtitle > c:\folder\movie1 - 6 - Subtitle (PGS), French.sup

Please and thank you.
Please keep up the good work.

I have been using this tool for awhile. I really like it.
And I try to prowl around this thread for information.
I find enough to get done what I want to do.
I even use the Google search function to try narrow my search.
But some things are just difficult to solve.

For instance...
When I use the -demux command, it doesn't demux to same folder as the source (most cases ".m2ts" files).
Instead it demuxes files to my Documents...

WinXP
"C:\Documents and Settings\(username)\files.*"

Vista
"C:\Users\(username)\files.*"

I have to copy the files to the desired folder.

And when I do use the command to demux to a different folder, it saves the files in the desired folder and the Documents folder, too.

Is this normal behavior? (in both cases)

Edit:
Scenario one: Demuxing without setting parameter for new folder

eac3to v3.24
command line: "D:\Apps\eac3to\eac3to.exe" "E:\Work\Bram Stoker's Dracula (Trailer)\MainMovie\DRACULA_TRAILER\BDMV\STREAM\00112.m2ts" -demux

@ Sparktank:

eac3to is a command-line application, so, by default, it outputs its results to the current working directory — which, by default, is the <opinion>stupid</opinion> user's homepath. The "best" policy is 1) include eac3to's directory in the PATH environment-variable, and 2) open the command-prompt directly in the target-folder (easy with Vista and Seven, requires registry-editing in XP).

thanks for the info.
I just extracted eac3to a working folder when i first downloaded it.
I'll have a look into these options.

Is this something to worry about and why these errors occur exactly (main movie in this Blu-ray is splitted on several m2ts files on the disc)?

I have question on the following two options of eac3to. Can one use these options to convert audio length to match the fps of the video. Basically if I have a audio from a NTSC DVD (23.976fps) then I can use the -changeTo24.000 option to convert it so that I can use it with video from a Blu-ray (24fps).

-23.976/...        define source fps to be "23.976", "24.000", "25.000", ...
-changeTo24.000    change source fps to "23.976", "24.000", "25.000", ...

[henryho_hk]

Doesn't Blu-ray's "24" also mean 23.976fps?

Yes.

No.

[sneaker_ger]

Well, most of the time "1080p24" actually means 24/1.001 fps in the Blu-Ray world, but tebasuna51 is correct in that Blu-Ray supports both 24/1.000 and 24/1.001 fps.

I used the following command line to do the conversion, I find that the runtime of the audio is still the same as the original. Am I doing something wrong or will the audio and video be in sync. The video runtime for the DVD and Blu-ray source are different.

\path\to\eac3to.exe src.ac3 dest.ac3 -448 -23.976 -changeTo24.000 +1000ms -log=log.txt

Only if the runtime is 0:16:41.000

We can't know. Put exact runtime or number of frames.

Here the parameter -24.000 does nothing.

dvd video (23.976fps) runtime is: 10619286 ms
blu-ray video (24fps) runtime is: 10631458 ms

When I used the converted audio while muxing if I add suitable delay it starts of in sync and loses sync progressively.

You can't normally just take a DVD track and expect it to fit with BD (slowed down or not) - Audition or similar is needed to do a waveform comparison to check for initial delay and any necessary cuts/inserts.
