eac3to - audio conversion tool

[Beastie Boy]

Thanks for the replies. I'll use an intermediate THD only track since this doesn't require any encoding and I can save it for future use (FLAC support on the NMTs maybe )

Cheers, Beastie.

Wow, I didn't know that. Thanks for the explanation.

You can't directly compare the audio delay values reported by eac3to and DGAVCDec because eac3to removes all video frames before the first sequence header, while DGAVCDec doesn't do that (I think). Because of that eac3to's audio delay values can be higher.

However, the audio delay with your two test streams was not really correct with the current eac3to version. The next build will use a different delay calculation for such streams with video frames before the first sequence header. The delay numbers will be higher compared to DGAVCDec, but audio should be in sync.

Madshi,

Previously I was using a trial version of ArcSoft TotalMedia Theatre and eac3to recognised the DTS decoder without a problem.

I found a 40% discount coupon for this software so I decided to purchase it. I uninstalled the trial version, then installed the retail version, now eac3to informs me that the DTS decoder isn't installed. Any idea why?

Is the TMT bin directory in your path? If not give that a try.

I am not sure exactly what you are asking... Would you be able to clarify exactly what I should check?

Thank you. :-)

Also, I was wondering if it must be the TotalMedia Extreme suite or is it ok to only install TotalMedia Theatre?

I ask this because I previously had TotalMedia Extreme trial installed and now I only purchased TotalMedia Theatre retail.

TM Theatre should be fine, it's all I have installed and the decoder works fine.

Could the old install directory still have the trial information. Maybe uninstall everything Arcsoft, delete the old install directories then re-install your full version.

Who know, it might work.

Search for "environment" in this thread. Adding the ArcSoft DLL path to that variable has helped some people in the past...

Still not working...

I added the path as suggested. My full path environment variable is as follows... %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Common Files\ArcSoft\Bin\

The strange thing is I have tried every way imaginable. I have installed it over a trial version where the DTS decoder was working, the full version then removes the ability for eac3to to access it. I have also tried installing the new TotalMedia Theatre on a fresh install of Windows... Nothing seems to be working.

I installed TotalMedia Theatre v2.1.6.126 if that helps.

Ryu77, try:

md c:\as
copy "%CommonProgramFiles%\ArcSoft\Bin\*.*" c:\as
copy "%CommonProgramFiles%\ArcSoft\MPEG Engine\*.*" c:\as

and add to you PATH environment variable c:\as

Ok, I've added those two lines "%CommonProgramFiles%\ArcSoft\Bin\*.*" & "%CommonProgramFiles%\ArcSoft\MPEG Engine\*.*" without the quotation marks... I am not sure what you mean by adding c:\as?

[komisar]

Ryu77, open cmd.exe and enter this 3 command. Go to "MyComputer->Properties->Advanced->Environment Variables" and add in "User variables" variable Path with value c:\as. If you already have Path variable, add to end of value ;c:\as

[Ryu77]

Thank you for your help komisar... But still no luck.

I have added the C:\Program Files\Common Files\ArcSoft\Bin and C:\as to the path in environment variables and I have run those command prompts you suggested but it's still not recognising the DTS decoder.

I'm starting to feel like I was better off with a "trial" version.

[komisar]

Ryu77, one more explanation. You need all files from ArcSoft\Bin and ArcSoft\MPEG Engine in ONE folder (in my example c:\as). Also you need point Path to this folder (in my example c:\as).
P.S. I also spent a lot of time searching for the decision. And now this work for me...

I do appreciate your persistence with helping me but nothing seems to be working.

I really can't understand this. I checked my other PC that has the DTS decoder working and I can see that C:\Program Files\Common Files\ArcSoft\Bin has been already added to the environment variables. This must have been done automatically with the older trial install. I guess newer retail versions don't do that anymore. However, one would think manually adding it in as we have done would rectify this... In my case this doesn't seem to work. :-(

TotalMedia Theatre, in the commercial variant of TotalMedia Extreme (which I have purchased too), is at:

C:\Program Files\ArcSoft\TotalMedia Extreme\Digital Theatre

You don't need to add anything to your path; though I'd add eac3to to your path, like: "C:\Program Files\eac3to" (or wherever it resides on your system)

[Ryu77]

Thank you asarian but I purchased TotalMedia Theatre not the Extreme suite.

I fixed my problem now...

This is what I did...

1) Uninstalled full retail version, then did a restart.

2) Installed trial version, tested eac3to and it worked, then restarted.

3) Tested eac3to again, still good. Ran full retail install again but chose "repair".

It's all good now. The trial (or older versions) must do something that the newer full version doesn't. Oh well, it's all working now... Yay. :-D

For anyone that's interested in purchasing ArcSoft TotalMedia Theatre or TotalMedia Extreme, the code that I used to get 40% off is "earlyxmas09". Just type this into the field marked "Please enter your coupon code here:" and you will receive 40% off.

[WildTexasChef]

Am I mistaken or will eac3to NOT convert DTS audio to AC3?

I tried running eac3to to convert a DTS audio track to AC3 at a bit rate of 448 and it would not convert. It would work fine at a 640k bit rate but not at 448.

Any ideas?
