What is latest version of FLAC that works with eac3to?
Can someone point me in the direction?

Thanks

[LigH]

Not sure, but probably one available at RareWares... I would be surprised of any recent major changes breaking compatibility.

Tested the latest libFLAC v.1.3.3.git-ce6dd6b5 for win32 (in RareWares) and work fine with eac3to.

Hello,
I was struggling today with eac3to errors during conversion. Initially thought the files were corrupt but had no issues when using other tools.
Finally I found out it was because of accented characters.
Using the last version of eac3to (3.34) in windows 10 CMD.

1. Command: eac3to "07 -- Veinte Años.flac" "07 -- Veinte Años.wav"
returns error: The destination file "eac3to 07 -- Veinte Años.flac 07 -- Veinte Años.wav" could not be created.
2. Command eac3to "Veinte Años.flac" "Veinte Años.wav"
creates file eac3to Veinte Años.flac Veinte Años.wav

Accented character "fools" eac3to which joins/mixes parameters.
Anyone has faced such issues?

[tebasuna51]

Work fine here:

C:\Portable\eac3to>eac3to "07 -- Veinte Años.flac" "07 -- Veinte Años.wav"
FLAC, 2.0 channels, 0:02:50, 16 bits, 800kbps, 44.1kHz
Decoding FLAC...
Writing WAV...
Creating file "07 -- Veinte Años.wav"...
The original audio track has a constant bit depth of 16 bits.
eac3to processing took 1 second.
Done.

Is it possible to extract the Dolby Vision stream out of a file created by MakeMKV?

Hi everybody, I need a little help. I try to convert a DTS-HD Master to "simple" DTS so my soundbar could do the job in passthrough.
Actually my source is:
Audio
Format : DTS XLL
Format/Info : Digital Theater Systems
Commercial name : DTS-HD Master Audio
Bit rate mode : Variable
Channel(s) : 6 channels
Channel layout : C L R Ls Rs LFE
Sampling rate : 48.0 kHz
Frame rate : 93.750 FPS (512 SPF)
Bit depth : 16 bits
Compression mode : Lossless

I try using Megui with "HD Stream extractor" and specify DTS instead DTS_CORE but when I check the generated file it have the same properties of above.
I try using "USEac3To GUI", I don't know if I have checked to good option but the generated file have same properties of the source.

Is someone can help me to convert DTS-HD Master 5.1 file to "simple" DTS ?

Thanks

eac3to "filename.dts" "filename_withcoreonly.dts" -core

Ok so simple to do it in command, so complicated with GUI lol

Thanks

I'm using eac3to in a video transcoding tool I'm writing and these sounds are, I won't say annoying.... , but not preferred... ;-)

I spent many weeks trying to find an answer to this exact question. The solution for me was to delete the 2 wav files in your eac3to install directory. Of course, you could probably rename them if you want to keep them around.

Welcome to Doom9's forum.

The answer was in next post:

I've been looking all over the forum and in the internet. How to use eac3to via powershell? I want to use the qaac codec and using UsEac3to (what I've been using for years) the command line output would be:

 "eac3to.exe path" "input mkv path" tracknumber:  stdout.wav delayapplied video frame rate frame rate change -progressnumbers -log = "file.mkv_Job_n.log"
| "qaac.exe path" -V n --ignorelength --adts --no-delay -o "fileoutput.mkv_0lang.aac" -

I've underlined every "unit" of info of the code to make ir clearer.

I've tried to do something like:

$convert_eac3to = -join ($moviefile, " ", $numbertrack, ": stdout.wav ", $frameratechange, " -log = 'logfile path' ", $qaac_path, " -V ", $audioquality,
" --ignorelength --adts --no-delay -o ", $audiooutput)

which is an exact copy of the other code but with variables so I can play with them, but, as expected, it doesn't work with: & $eac3to $convert_eac3to ($eac3to is the path where the exe is)

How would be the code? I guess @stax76 knows the answer as he looks almost the only one "fighting" for using Powershell. ^^

Thanks

EDIT

I've tried to understand much better the behavior of the command and I've tried to adapt it to Powershell, but it's not my lucky day.

& $eac3to $moviefile $numbertrack $stdout $timedelay $frameratechange > $qaac_path $audiooutput -v $audioquality --ignorelength --adts --no-delay

$eac3to: eac3to.exe with path
$moviefile: movie.mkv with path
$stdout: stdout.wav with same path as moviefile
$timedelay: i.e. +340ms
$frameratechange: i.e. -24.000 -changeTo23.976
$qaac_path: qaac.exe with path
$audiooutput: i.e. movie.2spa.aac
$audioquality i.e. 99

Sometimes it's necessary to call cmd from powershell:

1. using built in cmd functionality like mklink (powershell 5 has New-Item for symlinks)
2. certain kind of pipe

I've never researched the reason of the pipe problem, but I know how to call cmd from powershell, have a look at /s /c in the cmd console help:

cmd /?

If this does not work then you might additionally need a stop parsing command:

--%

Some of these ideas are originally from qyot27 btw.

[Snowknight26]

$eac3toPath = "C:\path\to\eac3to\eac3to.exe"
$input = "D:\"
$chapterTrackNumber = 1
$videoTrackNumber = 2
$audioTrackNumber = 3
$audioFormat = "flac"
& ${eac3toPath} "$input" ${chapterTrackNumber}: "Z:\temp.txt" ${videoTrackNumber}: "Z:\temp.mkv" ${audioTrackNumber}: "Z:\temp.$audioFormat" -log=nul > $null

Adjust as necessary.

@Snowknight26

That may work for extract, Harrenkyym try to recode to AAC with a pipe ("|" in command line, ">" in powershell syntax) from eac3to.exe to qaac.exe.
And seems that don't work.

[stax76]

Let's say you got a complex command line that does pipe and also has paths with spaces:

ffmpeg -i "D:\aa aa_temp\aa aa.avs" -f yuv4mpegpipe -strict -1 -loglevel fatal -hide_banner - | x265 --crf 18 --frames 4069 --y4m --output "D:\aa aa_temp\aa aa_out.hevc" -

If this command line is in a variable or for instance in the clipboard, you can run it in powershell like so:

cmd /c (Get-Clipboard)

Piping is the done same way Powershell as it is in cmd. | is pipe, > is redirect. However, since Powershell treats the results of all outputs as objects/strings, new lines get added to the piped data, so you can't do it directly by calling "process1.exe | process2.exe" without adverse effects.

You either have to use C# in Powershell or launch cmd via Powershell which doesn't have the issue.

$eac3toPath = "C:\path\to\eac3to.exe"
$ffmpegPath = "C:\path\to\ffmpeg.exe"
$input = "C:\path\to\input.ext"
$output = "C:\path\to\output.ext"
$trackNumber = 2

& cmd @('/c', $eac3toPath, $input, "${trackNumber}:", 'stdout.wav', '|', $ffmpegPath, '-i', 'pipe:', $output) 2> $null

Adjust as necessary.

[tebasuna51]

Yes, I see.

BTW execute cmd is the same than create a cmd file and launch it.
