eac3to - audio conversion tool

[mrr19121970]

I tried it 5 times again, and not once have I had the same problem. It must have been a fluke.

Thanks for looking though.

[mic64]

Thanks for the idea, but I get:


$ ls cdrom
AACS BDMV CERTIFICATE
$ wine /home/me/eac3to cdrom "1)"
The format of the source file could not be detected.


I should have mentioned that 'wine eac3to videofolder "1)"' works perfectly after the disc is decrypted and ripped to the hard disk.

you can´t just use the command like this:
eac3to /mnt/cdrom ....

you have to start with the letter that wine assigned for "My Computer".
it should look like this:
eac3to z:/mnt/cdrom/
then you can append the title.
eac3to z:/mnt/cdrom "1)"

OffTopic:

You know that there is an option to delete doubled Entries automaticly !

Thats an good working Workaround for that case ... not always perfect but an good option.

sorry but i don't know. can you tell me how and which programm you use??

Hello Madshi,

Thanks for your time and your application.

I have been using eac3 version 3.04, trying to convert a normal DTS track to another DTS track (just needed to resample the track to PAL format), but has been experiencing a problem with it.
Here is the message i got after all the wav files were created....

"Encoding DTS <1536kbps> with Surcode...
Found Surcode DTS Encoder version 1.0.23.0.
Surcode says/asks: "At least one valid source file must be specified to encode.".
Pressing the Surcode "Encode" button didn't seem to work...
Closing Surcode..."

I tried using version 1.0.23
I'm trying right now with version 1.0.21....... is this a known issue?

Thanks

[Thunderbolt8]

thanks!

can you comment on what the difference will be regarding the change to 2KB blocks from 1MB when reading from HDD? I am thinking to get myself another HD to create raid 0 in order to speed up eac3to processing and especially because I hope it will take away some load from the disk. when its reading from the same drive windows is installed on as well, then I hardly can do something else until its finished (especially the more bitrate the streams have and the more tracks are processed at the same time). would raid 0 be able to change that, or would it only speed up the whole process, but the HDD load thing would remain as now?

Surcode sometimes has problems with funny file names. Try renaming the DTS file to something very simple, e.g. "test.dts". Maybe that helps...

can you comment on what the difference will be regarding the change to 2KB blocks from 1MB when reading from HDD?
I found that reading physical discs is much faster when reading 2KB blocks instead of 1MB blocks. Don't ask me why, I don't really understand it. However, reading files from harddisk is about twice as fast with 1MB blocks compared to 2KB blocks. So v3.05 checks which drive the source file is read from. If it's a CDROM/DVD/Blu-Ray/HD DVD drive, 2KB blocks are used. Otherwise 1MB blocks are used.

I'd suggest not using raid, but just using a second separate HDD for video processing purposes. Not using the HDD where Windows is installed on should help a lot.

[DaMacFunkin]

Sorry Bit of a quickie question here: do you still need to have nero 7 installed to use this tool to decode DD+ streams to wavs? Thanks.

[Thunderbolt8]

hm the way I have it now is that the partition windows is on is the reading partition, but the output is placed on another drive. but still, the reading alone already delays the system quite much.
I thought it might be more effective that way to seperate the reading and writing process to 2 different drives, as its faster to copy stuff from one HD to another than just to different folders on the same drive or also to mux with mkvmerge to another drive than the one you are reading from. so eac3to doesnt behave in the same way?

[idbirch2]

Great, thanks for the useful update. Being alerted to forced English subs at the time of demuxing will save a lot of time messing around with SupRead/Rip.

Hi madshi,

Excuse me if this is already an option and I've somehow missed it, but can you please add an option to disable the second pass upon clipping being detected?

Eac3to already takes long enough to convert audio of decent length without doing two passes, and I don't always care about some minor clipping artefacts.

[madshi]

I don't know, you can test it for yourself. I think performance will be better with eac3to, too, but it might still slow the OS down. Try reading+writing from/to the non-OS harddisk. That might take a longer time, but I think the OS should be more responsive that way.

You can also try the "-lowPriority" switch. That might also help OS responsiveness (on the cost of longer processing time). This switch should especially well on Vista and Windows 7. It should also help on XP and older OSs, but not as much as with Vista.

Sorry Bit of a quickie question here: do you still need to have nero 7 installed to use this tool to decode DD+ streams to wavs? Thanks.
See first post of this thread.

Eac3to already takes long enough to convert audio of decent length without doing two passes, and I don't always care about some minor clipping artefacts.
I'd suggest to use e.g. "-3db" instead. That will lower volume a bit, which usually gets rid of clipping. As a result a 2nd pass will in most cases not be necessary, anymore. So this basically does what you are asking for, and has the additional bonus of getting rid of clipping. Of course it comes at the cost of generally lowered volume, whenever you use this switch...

How will the forced subtitles be shown? I have Apocalypto BD and it's doesn't show any subtitles being forced.
Here are some possible reports posted by eac3to:

[s07] Counted 23 forced subtitles.
[s08] Counted 167 subtitles.
[s09] Counted 158 normal and 5 forced subtitles.

This information is only posted after full processing has run through! It is not possible for eac3to to report this without reading the complete source files. So don't expect this information in the track listing...

[madshi]

Question:

Does anybody have a 6.1 or 7.1 speaker setup and a Dolby Digital EX capable AVR and the possibility to send 6.1 or 7.1 PCM via HDMI to the receiver and would be willing to do some tests for me? If so, please PM me (don't post in this thread). Thanks!

[jwdaigle]

I am having troubles getting the arcsoft decoders to work with eac3to. When I run eac3to -test, I get "ArcSoft DTS Decoder doesn't seem to be installed". Im running 3.04 of eac3to, and just purchased TMT (the download gave me .126). The codecs do work with Graphstudio (using render media file), so that proves they are registered.

So how does eac3to decide if TMT is installed? Does it have anything to do with these 2 lines from a Process Monitor output (the referenced file does not exist in my fresh .126 retail installation):

5:20:13.4001806 PM eac3to.exe 5220 QueryOpen C:\Program Files\Common Files\ArcSoft\Bin\RPAWINET.DLL FAST IO DISALLOWED
5:20:13.4003641 PM eac3to.exe 5220 CreateFile C:\Program Files\Common Files\ArcSoft\Bin\RPAWINET.DLL NAME NOT FOUND Desired Access: Read Attributes, Disposition: Open, Options: Open Reparse Point, Attributes: n/a, ShareMode: Read, Write, Delete, AllocationSize: n/a

Is the existence of RPAWINET.DLL in the arcsoft bin directory the test to see if it is installed?

I have already tried adding Program files\common files\arcsoft\bin to the path before running eac3to -test. I have also tried copying the 4 mag*.dll files into the eac3to folder from arcsoft. As I mentioned earlier, the codecs are registered (I had to manually register them using regsvr32). I didnt register all of them (only the ones that seemed to be needed for video and audio playback), but will try that later.

Any help greatly appreciated.

Hi Madshi

I didn`t tried new eac3to, but is it possible to "mark" subtitles which have forced subs inside by filename ?

I would like to see if thes special track is ONLY forced, or it is normal subs with forced inside.

Could be nice to know sometimes. Could you add this if it make sence to you?

BTW:

My Virus-Scanner shows now some funny Warning:

Is it possible to use Neroaacenc.exe and use a bitrate ? (instead of quality)
And profile HEv2 ?

And when i try to convert DTS-MA to AAC (without ArcSoft/Sonic), i have the message : "The libav DTS decoder doesn't decode the full DTS-HD information.". How will be my aac file ? Correct or not ?

Thanks :)

@madshi
Please can you solve this 'bug' :cool:
eac3to 6o321.wav dplII.wav -down2

WAV, 5.1 channels, 0:00:20, 16 bits, 4608kbps, 48khz
Can't downmix this channel configuration ($3f).
Internal error - unknown audio output format!

With mask channel $60f work but the output from FAAD decoder and OGGDEC decoder have WAVE_FORMAT_EXTENSIBLE header with mask channel $3f.

I know M$ prefer now $60f but say also to be backward compatible...

The two only free decoders with WAVE_FORMAT_EXTENSIBLE output are punished with this.

Or maybe you prefer support aac,m4a,ogg decode with libav?

[madshi]

I am having troubles getting the arcsoft decoders to work with eac3to.
There have been many problems getting them to work. Usually manually registering the filters and adding the path to the environment settings (and a reboot afterwards) has helped most people. Some people had success installing the trial version first and then upgrading it to the full version. Don't know what else to say right now.

I didn`t tried new eac3to, but is it possible to "mark" subtitles which have forced subs inside by filename ?

I would like to see if thes special track is ONLY forced, or it is normal subs with forced inside.
eac3to only knows this after processing has run through, but I guess I could rename the sup files as a last step. I'll think about it...

My Virus-Scanner shows now some funny Warning
False alarm. Please write a complaint to your anti virus company.

Is it possible to use Neroaacenc.exe and use a bitrate ? (instead of quality)
Yes. E.g. "eac3to source.whatever dest.aac -192".

And profile HEv2 ?
AFAIK, the Nero encoder automatically chooses which encoding methods to use, depending on the bitrate/quality. Anyway, eac3to currently doesn't let you specify whether HEv2 should be used or not. If you want full control over the Nero AAC encoder, you may want to use piping, see Greif's comment.

And when i try to convert DTS-MA to AAC (without ArcSoft/Sonic), i have the message : "The libav DTS decoder doesn't decode the full DTS-HD information.". How will be my aac file ? Correct or not ?
Correct yes, but slightly lower quality compared to what could be achieved by using a DTS-HD capable decoder.

Please can you solve this 'bug' :cool:
Will be fixed in the next build. This was supposed to work already, so I consider it a clear and simple bug.

Or maybe you prefer support aac,m4a,ogg decode with libav?
m4a and ogg containers are very difficult to support because eac3to doesn't even recognize their format. I'd have to write full mp4/ogg container parsers to make this work with the current eac3to code structure. I could add AAC decoding support with libav. But AFAIK the libav AAC decoder is not yet feature complete, so I'm afraid of adding compatability problems. I rather want to wait until libav's AAC decoder can decode all AAC formats before supporting it.

Hello. I have a question. I tried to encode dts from an lpcm track, In the middle of the process i got an error. This is only the 2nd time that i've used this program so i don't have much experience with it. I have here the log file and hopefully someone can tell me what i have done wrong. By the way, i have installed Surcode dvd dts.

Why isnt the ArcSoft TrueHD and ArcSoft (E-)AC3 supported but the Arcsoft DTS-HD is?

[lexor]

Why isnt the ArcSoft TrueHD and ArcSoft (E-)AC3 supported but the Arcsoft DTS-HD is?

Because it's a lot more work, and unlike DTS components there is no better substitute.

TrueHD - libav handles perfectly
AC3 - handled by Nero 7 (yes it's old and unavailable if you don't already have it... but libav is good enough here too)

On the other hand nothing handles the plethora of DTS formats quite as well as ArcSoft.

[mikelebron]

Makes sense... Question.. I noticed my MKVs that were remuxed from TrueHD, DTS-MA, or PCM to FLAC have a much lower volume... How can I correct this? Any tips?

[Snowknight26]

Any reason behind patching DTS source bit depth flag?

[jwdaigle]

I am posting this in the hopes that it helps someone else with a similar configuration to me. Before I got this working, eac3to -test would tell me that it doesnt like like the arcsoft dts decoder is installed.

I am running Vista32 Service Pack1 with no "codec packs" installed. My aim was to have the ability to play video files (usually in mkv files) with a minimum of crud added to my system.

Prerequisites:
- You have successfully installed Arcsoft TMT Retail. This info is not meant to help you pirate the Arcsoft codecs, but rather you bought the product and want to use the codecs outside of the TMT environment.
- You can play video files with the Arcsoft player (I did all my testing with .mkv files with 264 video inside). ie, the arcsoft retail product works on your machine.


If you cant do these 2 things, it is unlikely eac3to can use it.

I also installed the haali media splitter to be able to read mkv files.

Setup:
Really only two things are required.

- The dll files in C:\Program files\Common Files\Arcsoft\Bin need to be accessible in your path. Do this by going to control panel/user accounts. Select "Change My environment variables" from the left hand side. If there is already a Path variable in the top listbox, select it and click edit - if there isnt click on new. Type C:\Program Files\Common Files\Arcsoft\Bin in "variable value" and "Path" in the Variable name. Click ok/ok/ok.
- The Arcsoft audio codecs must be registered. I am not sure if I registered more than I needed to, but the ones I registered are: ASAudio.ax, ASAudioEffectHD.ax, ASAudioHD.ax, ASVid.ax, VideoRenderForEVR.ax, VideoRenderForVMR.ax. You can do this by running a command prompt as administrator (right click on command and select "Run as administrator") and typing regsvr32 "C:\Program Files\Arcsoft\TotalMedia Theater\Codec\each_file_in_my_list.ax"

You should get a "registration of ... was successful.

I then rebooted.

After this brief process, I re-ran eac3to -test (3.05 for me) and it now reported that it can see the arcsoft codecs.

I didnt need to copy any of the dlls around (thats what the path is for).

Success!

I also suggest that you get a copy of the (free) GraphStudio to more fully test that the arcsoft video/audio codecs are working well.

Hope this helps -

Joe

Hi Folks

*GOSH this thread is getting HUGE!!!

I've got a problematic source, which is a MPEG Program Stream with MPEG-2 video and MP2 audio at 192kbps. I want to transcode the MP2 to an AC3. Usual command results in this output:

So, it looks like there are some gaps. Fine, there are no sync issues with the source or the resulting AC3. However, the resulting AC3 has some nasty clipping during loud portions! Any way to fix this? I also get the clipping if I decode the MP2 to WAV, so it seems like that's where it's introduced.

I'll be watching. Madishi, if you want the MP2 I can provide it!

~MiSfit

[Blue_MiSfit]

Okay, so some followup.

I can only get a clean decoded WAV if I decode to 32 bit float (using foobar2000). Unfortunately my DP600 only takes 24 bit WAV or BWF PCM input... :)

Trying more things...

~MiSfit

[Blue_MiSfit]

Finally, success! I had to demux to MP2 with eac3to, then use foobar to decode to full 32 bit float, then use eac3to to encode this to AC3. It detected the clipping, fixed it, and there was much rejoycing!

Hooray!!!! This title has been bugging me for AGES!

The real question is - why couldn't eac3to detect this in the original MP2, and run a second pass to fix the clipping? This roundabout business wasn't much fun..

~MiSfit

[DrNein]

jwdaigle (Joe),

If only DTS decode is desired then the minimal files required are the filter (registered) ASAudioHD.ax, plus the libraries DtsDec.dll and dtsdecoderdll.dll. The others required in the path to allow using any filters are checkactivate.dll, MagCore.dll, MagPCMac.dll, MagUIEngine.dll, and MagUIInter.dll.

Do you find any of the other filters useful externally such as for playback with MPC-HC?

[ACrowley]

Makes sense... Question.. I noticed my MKVs that were remuxed from TrueHD, DTS-MA, or PCM to FLAC have a much lower volume... How can I correct this? Any tips?

You get exactly the same Volume when reencoding to FLAC

FLAC reencoding is lossless and no Volume/DynamicRangeCompression etc will be applied from FLAC encoder.

You Problem can only be caused by :

1. Youre using a Decoder in eac3to with Dynamic Range Compression or Dialnorm enabled.
-Which Decoder are you using in ea23to ?

2. Youre using a FLAC Decoder with some other Output Settings.
-Take Madflac !

3. Youre using a DTS/ TrueHD Decoder for Playback with some changed Volume Settings as like Normalization, Gain etc...
Which player/Decoder are you using for Playback

I think Nr 3 and or 2 is your Problem....

[madshi]

However, the resulting AC3 has some nasty clipping during loud portions! Any way to fix this? I also get the clipping if I decode the MP2 to WAV, so it seems like that's where it's introduced.

I'll be watching. Madishi, if you want the MP2 I can provide it!
Yes, please.

Hello,

I was trying to convert a 6.1ch DTS-MA track in a AAC-MP4 one using eac3to 3.05, keeping the original channels. Log says:


eac3to.exe English.dtsma English.mp4 -quality=0.30
DTS Master Audio, 6.1 channels, 24 bits, 48khz
(core: DTS-ES, 6.1 channels, 24 bits, 1509kbps, 48khz)
NeroAacEnc doesn't support 6.1 encoding. Will double the 7th channel.

Decoding with ArcSoft DTS Decoder...

Commandline is the following:

eac3to.exe English.dtsma English.mp4 -quality=0.30

IIRC NeroAACEnc manages to encode streams up to 8 channels. Am I doing something wrong?

[shambles]

with the new version, in case of truehd tracks, eac3to always removes zero-bytes after encoding to flac.. isn't the bluray truehd spec limited to 24bit? so wouldn't it make more sense to always truncate to 24bit and then do the extra pass if it's only 16bits?

AFAIK Nero can encode 5.1 and 7.1, but not 6.1. So eac3to converts your 6.1 track to 7.1 to make it encodable with Nero.

isn't the bluray truehd spec limited to 24bit?
Huh? TrueHD is *always* 24bit. Never lower, never higher. But it's possible that only some of those 24 bits are filled with actual data, with the remaining bits being zeroed out.

[shambles]

oh right. but then why is this happening:

As you can see the processing took anywhere from 1:03:00 to 1:44:00 which is much better than v3.04, but not as good a v2.87. As previously discussed via email, v2.87 performance was fast enough demux a 1:45 hour movie in 27 minutes.

What size blocks did you use in v2.87? Was it 4K blocks? Maybe it's better to go back to that size or even try 8K blocks?

One of the areas v3.05 really shines is reading disc structure ["E:\" and "E:\" 1)]! Much faster than v2.87 or v3.04.

As always, you work is really appreciated!:thanks:

AFAIK Nero can encode 5.1 and 7.1, but not 6.1. So eac3to converts your 6.1 track to 7.1 to make it encodable with Nero.

I didn't know that. :(

Changelog of version 2.51 says:

Release Date: Jul 1, 2008
* added (undocum.) option "-no7doubling" to disable 6.1 -> 7.1 channel doubling

This option doesn't exist anymore: may I ask what did it "technically" do?


BTW thanks for this awesome tool, keep up the good work! ;)

[nautilus7]

oh right. but then why is this happening:This is exactly what madshi explained to you, and because i can't tell in a better way, read it again from him.

[Blue_MiSfit]

@Madshi:

The clipping MP2 is uploading. I re-verified that both MPG -> MP2 -> AC3 and MPG -> AC3 both produce clipping, but MPG -> MP2 -> 32float WAV (with Foobar) > AC3 (with eac3to) works fine.

I'll update this post with the link when it's done uploading.

This is exactly what madshi explained to you, and because i can't tell in a better way, read it again from him.

but the log shows that the track has a constant bit depth of 24bits, so why is eac3to detecting zero-bytes and performing the 2nd pass? this is happening with all truehd tracks, i've done like 15 of them in the last couple days

Consider numbers: 1 , 01, 001, 0001 etc.

They are all the same, they are all 1. Prefixing a number with zeroes does not alter the value. TrueHD tracks are padded to 24 bits. So if source was 16bit PCM it would be padded to 24bits with zeroes by the TrueHD encoder. What eac3to is doing is detecting that padding and removes it on the second pass.

I ran into another MP2 source that had the same clipping issue today, and the same fix worked. If you need it, let me know.

there's no padding! the resultant flac tracks are 24bit. i know eac3to removes zero-bytes if there's only 16bits of valid information but these are all tracks that have full 24 valid bits
