eac3to - audio conversion tool

[rica]

Thanks Thunderbolt8 but i'm using eac3to conv. gui v2.00 and haven't seen any option?
Do i need another gui or shall i have to make this on command line?

[Thunderbolt8]

im not really familiar with the gui, as working with the command line is much more fun for me :P

[rica]

Can you pls give me the command line?
An SS i mean?

[rica]

This is the command line which gui creates:

"C:\Users\rica\Desktop\EAC3to\eac3to.exe" "F:\RED_DRAGON_G41\HVDVD_TS\FEATURE_2.EVO" "C:\Users\rica\Desktop\feature_2.ac3"

How should i modify this?

[Thunderbolt8]

im not sure if I understood you correctly what you want to do. do you only want to demux another .ac3 track from the disc other than the standard track?

btw. from the screenshot it looks to me you are only treating the 2nd .evo file, leaving out the 1st one?

@ rica,
Just use this tool.
If you are fond of command lines and repetitive typing you can learn the eac3to syntax from the command lines the GUI makes.

The answer of your question BTW:

From this track:

[Thunderbolt8]

is it possible to extract a core from a DD+ track? i only know this from DTS-HD or trueHD tracks. I guess you just want to convert DD+ to DD ?
then type it like that "....\eac3to feature_2.evo 3: ...\file.ac3" and if you want to specify a certain bitrate, for 640 kbits for example "-640" at the end of it like"....\eac3to feature_2.evo 3: ...\file.ac3 -640"

[rica]

Tnx, i gonna try.

Am I missing something? Sorry, I'm 80 pages behind, I've skimmed them, but things move so fast. I've read about some pulldown changes, but I don't think that's the issue (?).

Thanks

Mark

Well I tried it again with 2.46 and it worked, FPS were added to the MKV header. I dunno what happened last time, sorry.

madshi,
which aften-commandlines are used internally in eac3to for 5.1-AC3-encoding for the different audiostream-types.
It is just for my personal interest.
Thank you.

No success in command line...
I demuxed english audio stream with EVODemux; i got *.mpa.
Renamed it to *.ac3.
Opened it with eac3to and converted to ac3.
It worked this time.

The above command should have probably read:

"C:\Users\rica\Desktop\EAC3to\eac3to.exe" "F:\RED_DRAGON_G41\HVDVD_TS\FEATURE_1.EVO"+"F:\RED_DRAGON_G41\HVDVD_TS\FEATURE_2.EVO" 4: "C:\Users\rica\Desktop\feature_2.ac3"

Eac3to doesn't automatically join the files, so you were only looking at half of the movie. That's probably why TsMuxer had problems with it. You'll notice I chose track 4 instead of 3. This is because eac3to will list track 1 as "Joined EVO file", moving all of the tracks down one on the list.

An easier way to do it in the future is to do:
eac3to "path\to\movie\folder\"
which in the above movie would read:
"C:\Users\rica\Desktop\EAC3to\eac3to.exe" "F:\RED_DRAGON_G41\"
This will get you a listing of titlesets.
1)
2)
etc.

"C:\Users\rica\Desktop\EAC3to\eac3to.exe" "F:\RED_DRAGON_G41\" 1)
This will get you a listing of all of the tracks in that movie. Just add the tracks on after the above command line to demux.

does anyone know if certain characters in chapter files (like ? / or such) are forbidden? because I get a mkvmerge error now when I try to add chapters to a file which worked fine previously

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

I'm using the latest version of eac3to, as posted on the first page, and I'm using the command prompt. I have used the GUIs, but the result is the same.

This is the command I'm entering:

• eac3to 01.evo+02.evo 4: appleseedac3.ac3 -libav

I'm not using a rebuilt file (although I have tried it, and tried using a .evo where the audio track is thre only track in the file).

Thanks in advance for the help.

[rica]

Thanks a lot @Yraen, that was a great explanation; i'll give it a go..

[rica]

First i got the track info:



The track i needed was the third one.

Here is the command line:



Thanks to thunderbolt8 and yraen
(BTW: i might have made a spelling mistake yesterday.)

You're close, but not quite there yet. Your first pic is correct but it's not the track listing, this is a list of the titlesets and the tracks contained within said titlesets. Madshi pointed out somewhere back in the thread here that the titleset listing is not always in the correct order, this is just the order they are listed in inside the .xpl files.

In your second pic, you only got about half of the audio you wanted. You only linked to one of the two .evo files that make up the movie. In the first pic, look to the right of the 1), you'll see the files that are joined by eac3to to demux the audio/video.

The actual command line you want is:

"C:\Users\rica\Desktop\EAC3to\eac3to.exe" "F:\RED_DRAGON_G41\" 1) 4: "C:\Users\rica\Desktop\trial.ac3"

If you're wondering why I changed it to track 4 instead of track 3 run this command line and you'll see why.

"C:\Users\rica\Desktop\EAC3to\eac3to.exe" "F:\RED_DRAGON_G41\" 1)

The folder option is better than the file option in my opinion. It offers more information and options. You could change the titleset number 1) to 2) and get the "a director's journey - making of red dragon" audio and video. Very handy if you want to back up some of the extras on the disc.
