eac3to - audio conversion tool

[madshi]

The AOB files are 1 GB - how do I just get the 1st 20MB?
E.g. with a hexeditor like this one:

http://www.mh-nexus.de/

The shortest extracted MLP file is 120 MB - I could upload this one..
No, that wouldn't help much. I need a sample of the AOB file if you want eac3to to handle AOB files.

Bo Kaspers Orkester - Live DVD

eac3to can't find video in VOB.
"This doesn't seem to be a valid (E-)AC3 file."

And audio tracks have xxxxxxxxxxxxxxxxxx ms delay on them.

Anyway I demuxed vide with pgcdemux.

VOB->Sonic->ffdshow(libmpeg2)->YUY2
Correct AR

RAW->Sonic->ffdshow(libmpeg2)->YUY2
Incorrect AR

MKV (eac3to 2.25)->Haali->ffdshow(libmpeg2)->YUY2
Incorrect AR
Could you upload a little sample for me? Thanks! 30MB should do.

[nautilus7]

I can upload an AOB sample in 1 hour.

[rickardk]

Yes I will...
But how exactly should I handle DVDs?

eac3to vts_01_1.vob+vts_01_2.vob+vts_01_3.vob

Wich VOB should I make a sample of?
What to look for when cutting VOB (I guess I should use hex editor again?)?

Please try reproducing the problem with only the first VOB part. The problem will hopefully show up this way, too. If so, just send me the first 20MB of the first VOB file. You can cut with a hex editor. VOB files consist of blocks of 2048 bytes each. If the problem doesn't show up when using the first VOB part, only, things get more complicated.

Please do. Please the *beginning* of the AOB. 20MB should be enough.

Madshi,

I'm trying to convert an 88.2kHz 24-bit stereo (L)PCM file to WAV.
I couldn't get it to work with the PCM commands. With some command combinations, it converted but the WAV came out as noise. Otherwise, it kept asking me to specify the channels, bitdepth and endian.

I was using

eac3to track1.lpcm track1.wav -2 -24 –little -88200 -override

thanks for your help

[madshi]

I'm trying to convert an 88.2kHz 24-bit stereo (L)PCM file to WAV.
Where did you get that file from? Try "-big" instead of "-little".

[keysersose]

Here's a sample - I cannot be sure that it has the multichannel tracks or starts with the stereo songs as I'm only interested in demuxing the 5.1 tracks..

http://rs3l33.rapidshare.com/files/92866820/sampleATS_01_1.AOB

I *REALLY* appreciate your efforts!

[frenchglen]

It's from my own DVD-A disc, demuxed by DVD-A explorer tool. I'm archiving it on my PC.

Tried using -big but the same message came, "was not able to figure out all parameters of this RAW/PCM file. Please specify channel, bitdepth and endian parameters via command line."

[madshi]

Here's a sample
Thanks, will have a look. Might take a few days, though...

It's from my own DVD-A disc, demuxed by DVD-A explorer tool. I'm archiving it on my PC.
It is possible that demuxing was not done correctly. In that case there's nothing eac3to can do. Do you still have that original AOB file? If so, you could upload a sample for me to check out. Please don't send me a sample of the LPCM file, though, that would be of no use to me.

Tried using -big but the same message came, "was not able to figure out all parameters of this RAW/PCM file. Please specify channel, bitdepth and endian parameters via command line."
The "-override" parameter only works if you specify all necessary parameters (channel number, bitdepth, samplingrate and endian).

[frenchglen]

Does eac3to support 88.2kHz? Must I convert sample rate maybe?

If it was not properly demuxed, wouldn't that a big deal, considering DVD-A Explorer supposed to be the only tool currently that does it properly.

Will see what I can do with uploading sample.

[madshi]

Does eac3to support 88.2kHz?
Sure.

[frenchglen]

Ah, guess what, DVD-A Explorer has a little option to convert to WAV when demuxing a PCM track. And it plays back fine.

Still, would be nice to know it's possible in eac3to, if you want a sample I can send it to you some time.

Hmm.. The AR problem does show up on the first part. But eac3to can't find video track on the second part. So when using "eac3to vts_01_1.vob+vts_01_2.vob+vts_01_3.vob" ...I get message telling me that vts_01_2.vob is not a valid file

But if I just use "eac3to vts_01_2.vob" eac3to accepts it but there is no video in it and audio delay is like 56546546546546546 ms

I see that option to convert to wav but it's always grayed out - I can extract the AOB only to MLP files..

Any tips on how I could get the wav option to work?

am using version Alpha 7

[nautilus7]

AOB sample here (http://www.sendspace.com/file/ooo47s). It has mlp audio. To be honest i don't know if it has watermarking... It's a ripped dvd-audio.

Madshi, something else regarding 88,2 khz: is this sample rate supported in resample option, as well?

A sample would be welcome. I have two AOB MLP samples now, but no AOB LPCM sample yet...

Most probably you have an AOB with MLP inside while frenchglen has an AOB with LPCM inside. DVD-A Explorer doesn't contain a MLP decoder, so there's no way for DVD-A Explorer to convert the MLP track to WAV.

It seems that the VOB parts are sometimes cut in a strange way so that only the first VOB part can really stand on its own. EVOs seem to be cut differently. Every EVO I've seen has always started with proper video and audio frames.

Anyway, I'd still like to have a sample of the first VOB part because of the aspect ratio problem. I can fix the complaints about the 2nd VOB part without a sample.

[nautilus7]

A sample would be welcome. I have two AOB MLP samples now, but no AOB LPCM sample yet...Would you like me to make a sample with lpcm inside? Give me a few hours. :)

[madshi]

The more samples the merrier. Especially LPCM as there are several different format possibilities with LPCM.

It can only convert to WAV for PCM tracks (uncompressed PCM), not MLP tracks (PPCM, i.e. Packed PCM). In other words, DVD-A Explorer does not have an inbuilt MLP decoder.

You can see which one it is by the icon beside each track in the left pane, or in the stream type parameter in the right pane.

To convert MLP to wav/flac etc. we use Madshi's wonderful program!

Edit: whoops, already answered.

[Thunderbolt8]

have a question regarding .vc1 input files: with that option we could now also use it for blu-ray titles when we demux the video stream with xport first. my question now is what should make more sense, still continue to use gdsmux with the .m2ts file for the video or demux the video with xport and the mux it with eac3to to .mkv?

gdsmux had this problem that certain .vc1 information is dropped and therefore it *could* have problems with certain movies (though I havent had any blu-ray with these problems so far), but on the other hand, when demuxing first we dont have that complete video chain any more. so what would you recommand here (obviously the answer here would be to wait until eac3to supports blu-ray structure as well, but that one aside please) ?

This is the only one remuxed with eac3to that shows wrong AR. I use Vista Media Center, Haali Media Splitter and ffdshow (libmpeg2)

[madshi]

Here's a sample - I cannot be sure that it has the multichannel tracks or starts with the stereo songs as I'm only interested in demuxing the 5.1 tracks..
I think this sample is corrupt. Maybe it's still encrypted? I got two MLP AOB samples now. I've got one working fine. But this sample doesn't work. The MLP stream seems to be corrupt.

For all you guys friendly enough to send me some AOB samples. Could you please also add the "*.ifo" file so that I can cross check with DVD-A Explorer? Thank you!! (DVD-A Explorer needs the ifo file or else it refuses to work).

What do you mean with "the only one"? Did you already test all other 35-40 of your discs? :eek:

If you absolutely have to remux now I'd recommend to demux the VC-1 stream and mux it with eac3to because this will keep the full VC-1 stream intact. But doing it this way you will have to manually check audio sync carefully.

It could be corrupt..but I don't know why

When I open the original disc DVD-A Explorer says it is protected and won't let me decrypt

I then ripped the original files using DVDARipper and then DVDA explorer says there is no copy protection and allows the extraction to MLP like this:

track-06-[lf rf etc].mlp 121,966 file size

when I attempt to make a new dvd-a with the MLP file it's showing the length as only 1 second - it's for a sure a watermarked disc and this once again could be the problem..

[madshi]

This is the only one remuxed with eac3to that shows wrong AR. I use Vista Media Center, Haali Media Splitter and ffdshow (libmpeg2)
I've remuxed this sample to MKV with eac3to and here are my test results:

- ffdshow (libmpeg2) - wrong aspect ratio
- ffdshow (libavcodec) - correct aspect ratio
- DScaler MPEG2 decoder - correct aspect ratio
- Intervideo MPEG2 decoder - correct aspect ratio
- Nero MPEG2 decoder - correct aspect ratio
- CyberLink MPEG2 decoder - correct aspect ratio
- ATI MPEG2 decoder - correct aspect ratio
- Sonic MPEG2 decoder - correct aspect ratio

Do I need to say more? ;)

The MKV seems to be fine to me. It correctly reports an aspect ratio of 16:9. Now don't ask me why you get a correct aspect ratio when using VOB -> Sonic -> ffdshow (libmpeg2). I've really no idea. On my PC GraphEdit crashes when I try to connect your sample VOB to Sonic's HD Demuxer. And with VOB -> Haali -> ffdshow (libmpeg2) I also get a wrong aspect ratio...

I don't know how DVD-Audio decryption works. So I can't really help you here. For all I know watermarks are usually stored inside of the (PCM) audio data. So I can't imagine that the watermark is the problem. But what do I know?

Sorry for taking up your time with this one. As I got the correct AR when I played the VOB I did not test another decoder.

No probs. Did you try some other of your 35-40 discs, too? Do they work ok? Thanks...

[bertox]

If you wait a little i upload some DVD-AUDIO files...(going to my brother's birthday now...)

.:D

[nautilus7]

Here (http://www.sendspace.com/file/5idw2v) it's a pcm aob sample with its ifos as well as the ifos for my previous mlp aob sample.

[rickardk]

16 DVDs remuxed. No problem...
Will do more tomorrow

[trcolka]

I will not add any decryption logic to eac3to. Is that what you were asking for? Or do you have unprotected AOB files which you want to demux?

I was NOT asking for decryption, but for demuxing of an AOB-file which has no decryption/protection (anymore ;) )

[Thunderbolt8]

If you absolutely have to remux now I'd recommend to demux the VC-1 stream and mux it with eac3to because this will keep the full VC-1 stream intact. But doing it this way you will have to manually check audio sync carefully.
just as quick feedback, I tried both with gone baby gone now and just regarding the video stream theres a difference of 41ms, but when comparing audio sync both look absolutely fine. my guess would be that the way with demuxing and the using eac3to should always work regarding the normal audio/video sync at least for LPCM flac tracks, since these apparently always start at the same PTS as the video stream does, I havent seen any other case yet.

[keysersose]

WOW!!!

THanks Guys!!

[keysersose]

What will be interesting is to see if Ver8 does anything about the watermark..

I decided to try another watermarked disc with Ver 7 and this time my MLP files are fine and I was able to make a working DVD-A disc..:)

However the watermark is still there but I'm VERY happy because my house player is an Oppo and it ignores the watermark!

It won;t play in my car though which is a JVC..

[frenchglen]

Sorry about this off-topic stuff madshi...

keysersose: yeah, watermarking is still left to be undone by someone, but for the (minority?) of DVD-A titles that are watermarked, not all players have a detector and those with a HTPC and HDMI audio can play back ripped files/reburnt discs anyway. (well, that's another story...but it's possible)

Actually most of mine are watermarked but yes I was assuming they could be played on a PC thru HDMI and no more conversion to analog..

Alpha 8 works fine now on my 1st disc..:)

This is GREAT NEWS as this is a pretty fast solution..:)

[nautilus7]

You do realize that you're off topic, right? Thread is big enough, don't make it worse.

[Coolpplse]

The Sonic DTS decoder seems to be more or less perfect for DTS, DTS-ES, DTS-96/24, DTS-HD Master Audio and DTS-HD High Resolution tracks. Dialog normalization is ignored by the Sonic DTS decoder. The only "problem" of the Sonic DTS decoder is that it decodes DTS-HD 7.1 tracks only as 5.1. DTS-ES and DTS-HD Master Audio 6.1 tracks are fully decoded as 6.1, though.


Does this mean the Sonic DTS decoder decodes DTS MA Lossless in full blown lossless?

[madshi]

Does this mean the Sonic DTS decoder decodes DTS MA Lossless in full blown lossless?
Yes, with one exception: 7.1 DTS-MA is only decoded as 5.1.

[Thunderbolt8]

HD DVD is now officially dead with toshiba discontinuing to manufacture hardware -.-

[rickardk]

I get "lossless check failed" on some TrueHD tracks. Can this be ignored?
I thought this was fixed earlier...

[Sephiroth0000]

Hello everyone! Been awhile since I properly roamed through these pages and I have to say... WOW! Madshi and associated partners you have all done an amazing job. Anyway down to business. I have come to understand that EAC3TO can give you a Matroska video/audio file from your HD DVD source EVO. I have ripped my HD DVD and have the files but want to know now how to do it with the best settings. My reason being is so that I can then run the Matroska output file through MKV2VOB which will then allow the PS3 to play the file with no errors :)

[Thunderbolt8]

I'd say there are no real settings you have or can choose, for the video for example just choose the videotrack and output.mkv, that should it be. eac3to should aim for the best and less problematic way to remux automatically, only in rare cases you need to use one or the other switch for adjustment.

Thankyou Thunder. Would I have to load up audio or would it load with the EVO. Oh and also there are two parts to the EVO. How would I go about this in detail if you can please. Ultimately with a Matroska file you can feed it to MKV2VOB which does not recode the video at all but just changes it to VOB. Not too sure how it works but I know for a fact that PS3 will accept a VOB file with 5.1 AC3 audio. Does anyone what the video file is though within the Matroska file? Thankyou for any input anyone can give.

[Thunderbolt8]

generally when processing 2 input evos then you need to specify it like that "X:\path\first.evo+X:\path\second.evo" and then you can work with the different stream numbers e.g. 2: is mostly the main video stream then and the following ones are the audio.
so something like "X:\path\first.evo+X:\path\second.evo 2: X:\video.mkv 3: X:\audio.whateveritis(.ac3/.eac3/.flac etc.)" creates a .mkv out of the video stream from 2: and an audio track from 3: which can either be in its original format like truehd, dts-hd (which cant be muxed then though) or converted to ac3/eac3/dts/flac. what you need to do as last step manually then is to mux the video.mkv track together with the audio track in mkvmerge and voilà.
the video file will have the same codec as the source, since its a remux, so most likely vc-1 or h264, in very rare cases also mpeg2.

but dont ask me things about .vob, I cant tell you anything about that, sorry :P

[priyaradha]

hey Sephiroth0000, what a coincidence i am trying to follow you guide EVO to HD WMV but for some reason eac3 wont convert it to wav. I am running xp and installed nero 7.10, and all i get is this message

This audio conversion is not supported.

Could some one help me out..

[Thunderbolt8]

maybe using the -libav switch could help? (not sure if that accounts for wave format too though)
