eac3to - audio conversion tool

[Encoder888]

@madshi

It's a LOST episode, the two files are 1GB+0.7GB so it must have aborted at the end. It didn't even start demuxing, the line just ran across very fast and I got the error message. I've gotten the same error with about 3/4ths of whatever other movies I've tried, so I don't think it depends on the number or size of VOBs. I just use an older version of eac3to for those, I cant tell you for sure in which version the problem started, but 2.51 works fine.

[odin24]

I just made an attempt at using a TrueHD track on a HDDVD-->Blu-ray conversion using eac3to input.thd output.thd+ac3, and the end result was a choppy AC3 track, however I did use a DTS track in there as well and it played fine, as did the video. I used vc1conv for the video and tsMuxeR for BD muxing.

Does this command work for HDDVD-->BD conversions?

eac3to v2.62 crashes on this dtswav file.
sample (http://www.sendspace.com/file/b5utf9)

Tried v2.52 and it works just fine.

[nautilus7]

2.60 also works. Crash report says something about HD CD decoder. I believe DTS/AC3-WAV support is broken due to HD CD support.

[JustABDFan]

Hi,

1) I noticed that the libFLAC.dll that comes with Eac3to is 151,552 bytes and is dated 7/22/2007 while the one that comes in MadFLAC is 258,048 bytes and is dated 10/7/2007. I wanted to put Eac3to and Madflac into one "tools" folder so which I should use OR do I just make a folder for each and keep em separate?

2) Any chance of Eac3to using arcsoft decoders for (E)AC3 instead of Nero 7? Nero 7 Ultra isn't being sold by Ahead anymore and I don't want to risk buying the Blu-ray plugin to use with an OEM version then it not work properly.

Thanks.

[hdpete]

Is there anyway I can remux a blu-ray keeping the TrueHD track to fit on a BD25 for playback via a surround amp connected using HDMI. I know from a couple of costly BD-R's that tsMuxer won't allow the remux of TrueHD. I see that the latest version of eac3to can extract TrueHD as is, but how do I get it onto a blu-ray as I can't use tsMuxer?
I want to keep lossless audio, is the only way to use eac3to to convert the TrueHD to PCM 5.1?
Thanks

[Beastie Boy]

@hdpete, I have written a post in the tsMuxeR thread (http://forum.doom9.org/showthread.php?p=1181301#post1181301)that may help you. Please keep tsMuxeR questions there.

Cheers, Beastie.

Thanks madshi for your new version, for me the standard dts is all ok decoded but:

2/2.1 - ArcSoft output is FL FR FC Empty LF BL, the BR channel is missing and need remap -0,1,3,4,2,5

And using -dtslog with Samples_dts-es (http://www.sendspace.com/file/cohrtp) encoded with DTS PRO SERIES SURROUND ENCODER (thanks Elektra999) seems there are a detect problem:

Just a Q

What exactly can I expect when doing this command

eac3to BDMV k:\output.mkv ?
a complete mkv with all sound,subs ? or ?

[hdpete]

If use eac3to "D:\input.thd+ac3" "D:\output.wav" -nero -24, will the resulting wav file have all the lossless date of the trueHD source?
Thanks for your advice

[nautilus7]

First, .thd+ac3 is only accepted for input. Just use .thd. Furthermore, why use nero? Libav is the default TrueHD decoder because it works better. Finally, you don't need any -24 or whatever switch. All source data will be present in the output wav file. If source is 24bit, the wav will be 24bit, if it is 16bit, the wav will be 16bit. You will get a report about the actual bitdepth at the end of the procedure.

So your command should be:

eac3to input.thd output.wav

Althogh my source thd is 24 bit and the wav says it's 24bit, tsmuxer only recognises it as a 16bit, either way the -24 bit didn't seem to make a difference.
I'm usimg nero with blu-ray plugin as I thought it was a reference decoder as opposed to libav.
I just want to be able to convert TrueHD to LPCM to mux with tsmuxer to get a BD25 (tsmuxer doesn't like TrueHD). Previous converts using eac3to have resulted in screaching audio when muxed onto a BD25

Althogh my source thd is 24 bit and the wav says it's 24bit, tsmuxer only recognises it as a 16bit, either way the -24 bit didn't seem to make a difference.That's tsmuxer's bug, I'm afraid.
I'm usimg nero with blu-ray plugin as I thought it was a reference decoder as opposed to libav.What you say is true for the lossy decoders (AC3, E-AC3). All lossless fortmat decoders have to output the same data. That's the case with nero and libav TrueHD decoders. In addition libav supports up to 7.1ch when nero doesnt.
I just want to be able to convert TrueHD to LPCM to mux with tsmuxer to get a BD25 (tsmuxer doesn't like TrueHD). Previous converts using eac3to have resulted in screaching audio when muxed onto a BD25Again tsmuxer's bug. It supports pcm in a weird format. Use pcm2tsmu to convert eac3to's pcm files to tsmuxer's compatible ones.

[hdpete]

Again tsmuxer's bug. It supports pcm in a weird format. Use pcm2tsmu to convert eac3to's pcm files to tsmuxer's compatible ones.

Thanks a lot for this, I can start backing up my TrueHD blu-rays/HD-DVD's now and keep lossless audio for my Onkyo amp.

What file extenstion should I use to extract the 1080p blu-ray video using eac3to which will allow tsRemux to recognise and import it? Will it be a different file extention depending on the codec, i.e. H264 or VC-1?
Thanks for your help

Thanks for your help

I always change the container format to mkv and convert the audio to whatever format I fancy. So in my case the extension for the container wouldn't vary by video codec but the audio would. Clear?

Madshi,

I did some checking by downloading old versions and it looks like it was working in 2.54 but broke in 2.55. I'm gonna take a guess that one of these changes from the 2.55 changelog did it. I made some guesses but i could be wrong.

* improved VOB/EVO audio delay detection algorithm
* detection and automatic skipping of invalid vob units
* options "-60i" and "-24p" are no longer supported for MPEG2 video
* improved detection of MPEG2 framerate / pulldown state / mode (my first guess:confused:)
* improved MPEG2 muxing warnings (3rd guess:confused:)
* several bugs in MPEG2 video muxing fixed (2nd guess:confused:)
* fixed interlaced VC-1 muxing with user data (Nine Inch Nails)

I have trouble demuxing the MPEG-2 stream from VOB files. Here's what I get:

Small request madshi.
Could you rename first analyzing process from "progress:" to "analyzing:"
So instead of two "progress:" I would like to have "analyzing:" and then when stream is really demuxed I would have "progress:"

Thanks

I think the skipping of invalid vob units is the problem. I've removed that as a test in the next eac3to build. Please retest whether DVD demuxing works again. Thanks!

eac3to v2.62 crashes on this dtswav file.
Thanks for the sample. Will be fixed in the next build.

I wanted to put Eac3to and Madflac into one "tools" folder so which I should use OR do I just make a folder for each and keep em separate?
To be honest, I'm not sure. You can try using the newer dll for both. If you run into no problems then it's fine.

2) Any chance of Eac3to using arcsoft decoders for (E)AC3 instead of Nero 7?
Maybe some day.

Thanks for testing/reporting and for the new samples! The problems I could fix should be fixed in v2.63. However, ArcSoft seems to have problems with some 6.0 and 6.1 tracks. If I let ArcSoft decode them as 5.1, everything is fine. If I let it decode them as 6.0 or 6.1 the FL and FR channels are broken. Don't see how I could fix that. Funny enough Blu-Ray and HD DVD 6.1 tracks decode fine!! Because of that I can't simply block ArcSoft for 6.x decoding...

In this Swapping & Remapping being done twice, is it alright?
Yes.

For error reproduction I took working TS-file and splitted it (with TSsplitter) to 3221380 bytes chunks.
This is a problem. eac3to contains some extra code to handle Blu-Ray seamless branching correctly. Now if I make TsSplitter splitted TS files work that may eventually harm Blu-Ray seamless branching handling. Generally if you join some TS or m2ts files which were never stored in one file you'll want eac3to to do some extra checking/processing on these files. But if you join some TS or m2ts files which were once stored in one file and which you splitted with a tool like TsSplitter the extra processing makes joining fail. I'll have to think about how to handle this properly. For now you'll have to manually join the parts with TsSplitter first to make eac3to work...

* fixed: incorrect ArcSoft DTS channel remapping for "6.0" and "2/2.1" tracks
* fixed: v2.61+62 incorrectly decoded 16bit TrueHD tracks to 24bit FLAC/WAV/RAW
* fixed: some DTSWAV files made HDCD decoder crash
* fixed: DTSWAV and AC3WAV samplerate and bitdepth were reported incorrectly
* improved DirectShow channel configuration reporting

Good to know - thanks for the quick feedback!

[deathlord]

ArcSoft seems to have problems with some 6.0 and 6.1 tracks. If I let ArcSoft decode them as 5.1, everything is fine. If I let it decode them as 6.0 or 6.1 the FL and FR channels are broken. Don't see how I could fix that.

I assume the front channels are the same, no matter if you decode to 5.1 or to 6.1. You could check this on a working file. So you could take the front channels from a 5.1 decode and the rest from a 6.1 decode. Of course this is not beautiful, but it may be the best solution to treat these cases where it does not work otherwise.

While you are running tests with arcsoft, could you please also test what it does on a 6.1 track when you ask it to output 7.1?
I have more and more BDs with 6.1 audio and I can not play them back properly.

i believe that Sonic will work on such samples, so in that case better to use Sonic instead of Arcsoft. just decode the 6.1 DTS file with both Sonic and Arcsoft and if the two decoded files are different, probably the Sonic decode is the correct one.

hi

madshi you are the best. your prog works very well und your work is great.

a question.

i demux my sourcefiles ever with -demux.
then i get the video-,audistream and all .sups

is there a way to demux all audiostreams and .sups but without the videostream?

No, automatically. You can though choose which streams to demux by using the stream numbers (1:, 2:, 3:, etc) and the proper extension for each stream.

eac3to v2.41
command line: eac3to "H:\Testosteron HD DVD 1080p VC-1 DD+ 5.1" 1) 1: c:\tes\tes.txt 4: c:\tes\tes.dtshd 5: c:\tes\tes.sup

I assume the front channels are the same, no matter if you decode to 5.1 or to 6.1. You could check this on a working file. So you could take the front channels from a 5.1 decode and the rest from a 6.1 decode. Of course this is not beautiful, but it may be the best solution to treat these cases where it does not work otherwise.
I could probably do that, but I don't really like the idea to add such complicated workarounds for clear bugs in a specific decoder which is still being worked on. Maybe ArcSoft will fix that problem sooner or later? You could report it to their support forum...

While you are running tests with arcsoft, could you please also test what it does on a 6.1 track when you ask it to output 7.1?
Already tried that. The front channels are broken if I ask ArcSoft to decode 6.x as 7.1, too.

I have more and more BDs with 6.1 audio and I can not play them back properly.
I don't see why that should be the case. In my tests the Blu-Ray 6.1 tracks decoded perfectly fine with ArcSoft (as I already said earlier).

i believe that Sonic will work on such samples, so in that case better to use Sonic instead of Arcsoft. just decode the 6.1 DTS file with both Sonic and Arcsoft and if the two decoded files are different, probably the Sonic decode is the correct one.
Correct. Sonic works perfectly fine for XCh 6.1 DTS and DTS-HD files. However, Sonic doesn't work for XXCh 6.1 tracks, and it also doesn't work for XCh and XXCh 6.0 tracks. Not much of a problem, though, since 95% of 6.x tracks are XCh 6.1.

Just noticed that I forgot to add something to the changelog:

* option "-no7doubling" is not supported anymore
* option "-double7" added which upconverts 6.1 to 7.1
So by default 6.1 tracks are not upconverted to 7.1, anymore. You have to manually activate that if you want upconvertion. Also doubling the 7th channel now also halfs the volume of the 7th channel. Which is what ArcSoft's decoder is doing, too, when it doubles the 7th channel.

You have also forgot to remove these options from the command list:

-stripPulldown strips the pulldown from MPEG2 video tracks
-24p/30p/60i force the use of the specified framerate for h264 muxing

:p

Right! Removed that now... :)

-stripPulldown strips the pulldown from MPEG2 video tracks
That one is still needed. MPEG2 pulldown removal is activated automatically only for m2ts and evo sources, but not for demuxed MPEG2 files nor for VOB or TS sources.

Wasn't aware of that case. Thanks for explaining.

Neither am i; this should be added on the first post i think.

[Atak_Snajpera]

undocumented option -progressnumbers now outputs "analyze:" and "process:"
thank you very much!

eac3to v2.63 released
:thanks:

[nurbs]

Can eac3to demux blu ray subtitles (PGS) and, if yes, what file extension do I have to use?

[Snowknight26]

Yes, .sup.

[nurbs]

Thanks. I tried .pgs and it gave me an error. Also there is nothing about it in the first post so I wasn't sure if it was supported.

You can always use demux to see what extensions are being used, just control c when you have determined what extensions eac3to uses.

Hi. New to this tool. Worked on one DTS file but the second one threw an error ERROR: block code look-up failed
[dca @ 68A532E0]Didn't get subframe DSYNC. It seems to create an ac3 file but I can't test right now.

Also I have Arcsoft Total Media Theater installed but eac3to does not seem to realize it and won't use that decoder. It uses libav instead. Anyway to force it to work?
