eac3to - audio conversion tool

[musicman2311]

i have nero 7 and nero 8 - installed nero 8, so eac3to does no longer work.
is it possible to register the nero 7 filter on top and make it work ?
thanks for any help

ok - sorry all - i found the libav option....

[Jodo McFatty]

Sorry there are just too many pages and the "search" function tries to say my query which is 7 words is too short...

I get the following error when using eac3to:

DTS, 5.1 channels, 1:34:29, 24 bits, 1536kbit/s, 48khz
Decoding with DirectShow (Nero audio decoder 2)...
"getting "nero audio decoder 2" instance failed

I am using Vista, which as far as I know doesn't use DirectShow so not sure if that is the issue.
Also I have Nero 7.7 but is there a specific file I'm looking for or a place it needs to be located?

Thanks

[hristoff2]

did you buy HDDVD & Blu-Ray Plugin for Nero?
(Nero has to be v.7.8.5.0 or higher but not Nero 8)

[Jodo McFatty]

While I didn't buy the plugin(shouldn't need just for dts to ac3) I only had 7.7 installed. I'll try again with the newer one.

plugin should be for TrueHD which makes sense.

[nautilus7]

I believe the plug-in is needed in order the nero decoders to work. All of them. Start by updating your nero version to the latest 7.x.x.x and if still doesn't work buy the plug-in. But remember you can always use the free libav decoder.

[K-rnivoro]

You are correct. It is just matrixing the original PCM and setting a couple flags. As for the matrixing, I haven't looked into exactly how to do it. But here are the flags:
AftenContext.meta.xbsi2e = 1;
AftenContext.meta.dsurexmod = 2;

Definitely, the 7th. Center surround channel in a 6.1 DD EX stream is matriced using both rear surround channels, and I'm also sure it is adding one to another CS= (LS + RS) x A
That's because DD EX has to be compatible with AC3 5.1, which playback the CS on both LS and RS channels so it's an addition and not a susbstraction.
The "A" factor is unknown (by me) and also de flags.
Maybe looking at how Sound Forge does it can help (http://forum.doom9.org/showthread.php?t=124721)

I'm hoping someone can help. I'm trying to convert 5.1 DTS audio to 5.1 DD but when I run eac2to.exe, I get the following error;

The DirectShow audio decoder didn't accept the input stream.

I have Nero 7.10.1.0 installed. Do I need to install anything else? Or is there another decoder I can use? (preferably free)

Just noticed I can use libav, which appears to be working. Is this as good as (or better than) the Nero option?

[nautilus7]

Please, read the 1st post. It clearly describes which decoder is the best for each audio format.

To make nero decoders to work you need to buy the hd dvd/blu-ray plug-in.

There has been other discussion in this thread about this movie related to rainbow frames, but I have not seen any discussion regarding audio syn. Any suggestions as to how to resolve this issue would be appreciated.

I successfully managed to convert Stardust to .mkv. Eac3to worked flawlessly. The crash report would be useful (for madshi, not me :p). I can only suggest you trying using as input one of the two evo files and maybe doing an audio conversion instead of a video one. Tis way you might narrow down the problem.

That's it for now, at least from me (can't help you further). I think you have to wait a few days, because something tells me madshi is writing his H264/AVC splitter!!! :)

After processing with eac3to and merging with mkvmerge the resultant .mkv exhibits audio sync problems throughout the entire move.Is the audio sync problem the same (constant) during the whole movie? How much approximately? Maybe the automatic delay didn't worked.

[saint-francis]

Strange issue here with both EVOdemux and eac3to. They both tell me that you me and dupree has 6 audio tracks. I know that the movie actually has 5 tracks. Here is where it starts to get real weird. When I read the .xpl in EVOdemux the sixth audio track disappears. Eac3to still demuxed 6 audio tracks. When I try to convert the mysterious sixth track to .ac3 the resulting file is 500 MB but has no sound. :confused: I know that the read .xpl function in EVOdemux is a little wonky (on the same movie it also told me there was a separate VC-1 track which disappeared upon .xpl reading) but I have never encountered eac3to doing this kind of thing too. So what is this mysterious sixth track? Is the .ac3 that eac3to made from it just 500 MB of silence?

[nautilus7]

Did you try the -demux option in eac3to? Does it output a sixth track? Can you playback it with any media player program? Did you try PowerDVD? What does it report? Does it playback the sixth audio track?

Really strange problem indeed!

[saint-francis]

MPC plays the .ac3 but no sound. PDVD doesn't play the eac3. How can I demux only one track?

[nautilus7]

You can do:

eac3to 1st.evo+2nd.evo 9: audio.eac3

Run the track through delaycut to see what reports.

[saint-francis]

You can do:

eac3to 1st.evo+2nd.evo 9: audio.eac3

Should I:

eac3to 1st.evo+2nd.evo path\to\9: audio.eac3

Or

eac3to 1st.evo+2nd.evo 9:path\to\audio.eac3

Thanks for your patience with the small stuff. ;)

[nautilus7]

The 2nd. It's track id: and then path\to\filename.extension

[kmitalian]

i also have been hit with this crash problem with Transformers, but it also crashes the bug report, i dont know why but it happens.

[saint-francis]

OK. Same problem when I demux it. The .eac3 track is 150 MB and when I encode it to .ac3 the resulting file is 500 MB and doesn't produce any sound when played. The .eac3 track doesn't play in PDVD.

I tried to demux the suspect track alone as we were discussing earlier but I couldn't get it to work.

Here's what I did:

E:\software\eac3to>eac3to.exe D:\ymad\DVD_VOLUME\HVDVD_TS\FEATURE_1.EVO
+D:\ymad\DVD_VOLUME\HVDVD_TS\FEATURE_2.EVO :9 D:\ymad\strange track.eac3 -demux

Also, How can I use eac3to to demux the second video track?

[Yraen]

Try this
"E:\software\eac3to>eac3to.exe" "D:\ymad\DVD_VOLUME\HVDVD_TS\FEATURE_1.EVO"
+"D:\ymad\DVD_VOLUME\HVDVD_TS\FEATURE_2.EVO" 2: "D:\ymad\video.mkv" 9: "D:\ymad\strange track.eac3"

You don't need -demux unless you're wanting to demux the first video track and all audio tracks. You had the : before the 9 and it needed to be after it. Change the mkv to vc1 if you only want the video and not muxed into an mkv container.

[Yraen]

i also have been hit with this crash problem with Transformers, but it also crashes the bug report, i dont know why but it happens.

I had no problems demuxing or muxing into an mkv. Can you post your command line and any other information that may help someone see what might have went wrong?

[intomed]

I too had absolutely no problems with The Transformers.

[tjf]

I successfully managed to convert Stardust to .mkv. Eac3to worked flawlessly. The crash report would be useful (for madshi, not me :p).

That's it for now, at least from me (can't help you further). I think you have to wait a few days, because something tells me madshi is writing his H264/AVC splitter!!! :)

I reripped the movie again. This time I did not rip it over the network and it went without error. There is probably a bug in AnyDVD HD which causes incorrect rips if the saving is slower than reading.

I will now try Transformers.

Edit: I tried the 'corectly' ripped files on the compter where it crashed yesterday and it crashed again. I noticed I had some old version of Haali splitter installed there. So I reinstalled Haali and now am trying my luck again.

Edit2: It is still remuxing, but already past the crashing section of the EVO files, so the old Haali splitter version was really the problem. Madshi you probably plan to get rid of Haali splitter altogether, but maybe version check meanwhile would be a good idea.

[rickardk]

The Fugitive HD DVD did not work before. But plays perfect remuxed with eac3to v2.20!!

[Nikos]

I had no problems with The Transformers muxing into an mkv.

[Thunderbolt8]

regarding babel, the rainbow frames seem to be an ffdshow problem, as coreavc is reported to work fine here.
I also remuxed this title and I couldnt experience any audio desync. I have to say though that this is afaik the 2nd highest hardware demanding title I had so far (only ghost in the shell AVC is more evil, at least for ffdshow) so audio desync might easily be related to insuficcient CPU power here. I used a pre-2.15 version back then, but I can hardly imagine v2.20 should have introduced new errors here (still not completely impossible, though)

[rickardk]

Is there a way to solve video gaps?
Only title with video gap before was Born on the 4th of July. But with later eac3to version gap was not there.

Gap of 3 frames in Matrix Revolutions...

Hi Madshi

Got a slight problem...

Im trying to re-encode a bluray pcm track to standard ac3 -640

I've used xport on the m2ts file and then used eac3to to convert the track to ac3 however the audio is way out of sync with the video. I've never had this with a bluray before - only time I've had audio sync delay needed is with hd-dvds

Any ideas?

Not sure if its worth mentioning but i remapped the channels in eac3to

Thanks in advance and thanks for a great bit of software :)

[uk_dan2k]

I havnt got the gui version to convert anything yet, i select a .dtshd file (i think it should be renamed this, its a 5.1 dts track 768kbps).

i select ac3 file, at 448kbps and convert,

command comes up and types the stuff in, and and error comes up all the time.

'and' is not reconised as an external or internal command

command preview looks as follows: -

eac3to.exe "C:\Documents and Settings\dan.NONE-ED659932EF\My Documents\My Videos\HD movies\The Bourne Identity\film2.dtshd" "C:\Documents and Settings\dan.NONE-ED659932EF\My Documents\My Videos\HD movies\The Bourne Identity\film2.ac3" -448

any help would be great.

[Rectal Prolapse]

I don't know how those of you with trouble ripping transformers use AnyDVD to rip, but I ALWAYS use the "Rip to hard disk" item from the tray icon menu.

Doing it from explorer is *unreliable*.

It has to do with the spaces in the path/file names. Someone had the same error some weeks ago, but i don't really remember what the solution was.

Is the gui necessary? I mean it's not that difficult to use the cli, right? Btw, isn't the gui outdated?

As i said earlier - have used this method of re-encoding for months now and never had an audio sync issue with a Blu-Ray source - really strange to me

Thanks again for any advice

[nautilus7]

You have sync problems with the encoded video, right?

Unless you got any errors during eac3to processing (you would have told it otherwise :p ), it shouldn't be an eac3to related problem. I believe it has to do with the video processing part. Maybe there's a problem in your graph and some frames got lost or whatever.

You have to ensure that the audio sync problem exists with original video. I suggest using gdsmux (comes with haali media splitter - located in the installation folder) to mux original video to matroska (you can demux video and mux it to mkv directly also). Then add the .ac3 track to that .mkv file and test audio/video sync. If you still have problems, try a different audio conversion with eac3to (you can actually do this first of all).

What movie is it? Maybe someone has experienced similar problems. Why are you encoding it to mpeg-2?

which movie is it exactly? is this maybe also a seamless branching title?

if not and there really should have been a sync problem, what kind of problem? a general, fixed delay? a delay which increases thoughout the movie?
drmpeg (the xport author) said it might be possible that different audio stream e.g. lpcm and eac3 might behave or start differently in blu-ray, so maybe in this case reporting this to him might help, if this problem can already be solved at the demuxing stage.

[umaximus]

I have just finished remuxing bourne trilogy, and i noticed that the audio delay on Bourne Supremacy for english EAC3 is a bit off.
Eac3to reports it as +1001ms (also evodemux), but i found out that additional 300ms is needed for more accurate lip sync. Can anyone confirm this?

btw, remuxing with latest 2.20 version

[nautilus7]

I have Bourne Supremacy. I can start right now the conversion, results soon.

Great! I found a good 1min part for checking lipsync on 24min50sec (conversation between Pam and that man)

Well, i did notice an issue here! Are you sure that the same problem doesn't exist when playing the HD DVD? I can't test right now.

Its Reign of Fire - Its not a seemless branching title although the main feature is split over 2 m2ts files which to start with I joined with copy /b and then ran through tsremux. The audio was around 3-4 secs behind throughout from what I could tell. So I tried re-encoding each m2ts file seperately last night and had the same results...

I will try an encode with FFDshow or sonic tonight and see if I get the same results - this may narrow down whether its a video or audio problem.

[umaximus]

Yea, as I was comparing mkv to original evo, and in evo the audio sync is fine.

[nautilus7]

This is weird. I would respond sooner, but I was looking for this (http://forum.doom9.org/showthread.php?p=1094820#post1094820). Maybe there is a problem with delay when it's bigger than 1000ms. Don't know. I will do some tests (tomorrow) to be sure whether the delay value is applied correctly.

[umaximus]

The highest delay i found was on 12 Monkeys (+4471ms), and it seams just fine, dunno why its not right with Bourne Supermacy.

[nautilus7]

Yeah, it seems you 're right. The 1001ms delay is applied fine.

[umaximus]

Yea it is applied, but still not enough :confused:

btw, i also noticed on Bourne Ultimatum and Eastern Promises, that when using ''eac3to feature_1.evo+feature_2.evo'', the trueHD track is not showing any delay, but when eac3to starts muxing it, it applys +5ms of delay. Not that is noticable, but still, why is doing it?

[nautilus7]

Does it write any message that applying a delay? Or do you mean that the converted track is 5ms delayed compared to original? If the second, it's normal. For example when you encode to ac3 (regardless the source track) you get a ~10ms delayed audio. It has to do with the way the encoder works.
