There are some cases where the evo filenames aren't the proper, so evodemux can't detect both. Renaming them to feature_1.evo and feature_2.evo always works.

a little suggestion: when I try to slowdown a ac3 track I have to type -libav additionally each time, because nero cant do that. so would it be possible to set that -libav switch as default for ac3 slowdown(or where it is else concerned as well) ?

Why can't you do it? I have decoded many ac3s with nero and applied slowdown the same time. You shouldn't get any problems. Decoding is a completely different stage than slowing down and takes place afterwards.

dunno, each time I type 'eac3to input.ac3 output.ac3 -slowdown' i get the message that this type is not supported (nero audio decoder2) or something like that, so that I have to type '-libav' each time to have it work. so I was just wondering if it doesnt work with nero anyway, then it would make sense to set the -libav switch as default for this option.

Is the input 640 kbps? I think that eac3to gets confused because input file type and bitrate is the same and tries to slowdown without decoding, which of course isn't possible. When you set the -libav option it understands that it should decode and everything works fine.

You can do it in 2 steps:

Code:
eac3to input.ac3 temp.raw -slowdown
Code:
eac3to temp.raw output.ac3

the input varies between 2.0, 5.1 - 192, 384 and 448 kbit/s files -> tv sources

Anyway, then only it has to do with the filetype being the same. It should work in 2 steps.

Dear Thunderbolt8, you are wasting both nautilus7's and my time by posting error reports which are as unspecific as that. Furthermore with this type of error reporting you're blowing up the size of this thread. Your error report should be one post long and contain all necessary information. Now your one little problem has already consumed 7 posts in this thread and still nobody knows exactly what your problem is. (At least I don't.) Is it really so difficult to post the eac3to log!?

frankly said yes, because that copy&pase thing from the dos box somehow worked for me only randomly. anyway, Ill try again.

Code:
X:\eac3to>eac3to X:\input.ac3 X:\output.ac3 -slowdown
AC3, 2.0 channels, 2:35:13, 384kbit/s, 48khz
Decoding with DirectShow (Nero Audio Decoder 2)...
The DirectShow audio decoder didn't accept the input stream.
I get this result for all TV sources I wanted to slow down so far, as I said above 2.0, 5.1 sources with 192, 384, 448 kbit/s. each time, I had to type -libav manually, thats why I just wondered whether it might make more sense to add the -libav switch as default for this slowdown type, since one of eac3to aims also seems to be simplicity for the user.

Are you able to decode the ac3 file to wav or raw without any option set? I believe not... which means your problem has nothing to do with the slowdown thing.

The eac3to log is saved in the log.txt located in the same folder as the program.

nope, the same error message :S
so its a problem with the ac3 stream (which otherwise doesnt give me any problems though)? im just curious, because as I said I had to use with with every TV source I slowed down so far, while some of them indeed had little errors I had to solve with delaycut, but others were clean.

Hey folks new to eac3to. I have small issue thats probably simple but not sure since I dont have a lot of experience with this. I jsut demuxed a DD+ stream from anHD-DVD and am tryingto convert it to AC3. However I am getting a "Conversion not supported" error and not sure what it means. Wrong codec? I have Nero 7 essentials and thought that was all I needed. Am I incorrect? Any help would be greatly appreciated. Thanks.

And you can also pipe the output to a text file. You just need to do a little "cleaning up" afterwards, e.g.,
eac3to input.ac3 output.ac3 > output.log.txt

The cleaning up steps are simple. In Notepad, you can do an Edit | Replace pretty quickly:
- replace two dashes "--" with nothing
- replace two spaces " " with nothing
- first copy the LF character, past it in the "Find what" box and replace with nothing

It may seem like a lot, but once you do it a few times, it's pretty quick.

Unforunately I do not know how to create a logfile ( total newb) so I'll jsut write it out

"eac3to.exe "C:\Documents and Settings\Daniel Palacio\My Documents\WMV File Maker\output.ddp" "C:\Documents and Settings\Daniel Palacio\My Documents\WMV File Maker\output.ac3" -640 -nero
E-AC3, 5.1 channels, 3:07:22, 1536kibits/s, 48khz, dialnorm: -27db
This audio conversion is not supported."


Thats my result.

eac3to saves a log file of the last run command and its output in log.txt. Copy/paste from there next time.
Try changing the path to just "output.ac3", remove -640, and change -nero to -libav.


Also, will eac3to get DTSWAV support?

I just recently got Surcode, and have now started doing DTS conversions. However it is ridiculously slow. I believe the problem is that the 6 wavs are being loaded, and the DTS file is being saved to the same hard drive.

I was wondering if it would be possible to add something like "tempFiles" flag. This way we could make sure that different hard drives are used for the wavs & DTS file (or any other conversion that needs temp files).

Thanks!

On a Q6600, it takes about 10 minutes to write a 2 hour long DTS file thats, say, 1.2GB. Doing some calculations, that turns out to be 2MB a second + 6*1.377MB/s for the WAVs = just over 10MB/s. With a HDD read/write speed of 70MB/s, I can assure you that its CPU limited, making it unnecessary for what you're asking.

Hey madshi, I've stumbled upon a PCM track that eac3to can't handle. It's the new Phantom of the Opera BluRay (AVC video + PCM audio).

Output from eac3to:
Quote:
This might be a RAW/PCM file. Trying to figure out the details.
This will probably take a while. Please be patient...
The RAW/PCM file seems to have a bitdepth of 16 bits.
The RAW/PCM file seems to be big endian.
The RAW/PCM file seems to have 6 channels.
RAW/PCM, 5.1 channels, 2:21:06, 16 bits, 48khz
This audio conversion is not supported.
edit: Sample is screwed and it was me being dim with the command line - I'd left the "-640" parameter in my command line. Doh.
