eac3to - audio conversion tool

The thing is when ever I have a delay, say in a EVO file, if I demux the ES streams from the container with EVOdemux then run them through eac3to it seems to remove the delay but my streams always play fine and in synch. Actually when I let eac3to process delay it sometimes makes my files out of synch after remuxing with tsMuxeR. To be safe if my streams have delay reported by eac3to I always demux to get rid of the delay. It has seemed to work every time for me.

@madshi

FYI, "ArcSoft Audio Decoder HD" build 113 TrueHD 7.1 decodes are bit-perfect, byte-by-byte identical with libav.

so, looks like the ArcSoft decoder is very interesting.

[Thunderbolt8]

madshi, would it be possible that you could output more of the undocumented switches (either here or in eac3to) ? I have a problem with a .m2ts file and am looking for that switch to ingore possible errors now, but since its not documented in eac3to I cant find it.

hi guys, i have 3 little question about eac3to

do i need anything to let eac3to create the .mkv file ? or is it a problem with wine, i hope not ..

"[a04] Applying (E-)AC3 delay..."
i convert the .eac3 to .ac3, and i will mux it with mkvmerge with the abc_movie.mkv file, what have i to do with the "-80ms delay" ?
.... i must set -80 ms in the mkvmerge(gui) ? or does eac3to change anything on the delay ?

[odin24]

I just tried to convert a LPCM track @ approx 7MB/s to DTS @1536kbps using eac3to with eac3toGUI. I used the sonic filter and Surcode is intstalled on my PC. Everything started fine, the single 5GB LPCM file was split to six single channels by eac3to then the recode began and finished after about 15 minutes. I then tried to load the file in tsMuxeR but it came back "cannot detect stream", any ideas?

Also, in eac3toGUI the default output was AC3, I changed it to DTS.

Thanks in advance.

I've been using eac3to for some time with no problems on both BD and HD-DVD. Just starting tonight I get the following error:

D:\LIAR_LIAR>D:\HDDVDTL\eac3to feature.evo
The (E-)AC3 reader didn't receive the format information.
The (E-)AC3 reader didn't receive the format information.

Here is another example:

This doesn't seem to be a valid (E-)AC3 stream.

And one more just to be sure:

I checked my codecs and utils with -test, and all seems okay.

D:\HDDVDTL>eac3to -test
Nero Audio Decoder (Nero 7 or older) works fine
Sonic Audio Decoder (4.3.0.169) works fine
Haali Media Splitter (2008-3-29) is installed

MkvToolnix (v2.2.0) is installed

D:\HDDVDTL>

Even if I read directly from the HD-DVD disc, I get the same error. Different titles from other of my HD-DVD discs give the same error too.

Did a check disk, and HDD is fine. Nero is v7.11.10.0. Finally, I'm using Windows XP Pro SP3. And yes, everything was working fine even after I installed SP3... at least for a while.

Anyone have an idea what's going wrong here?

Thanks.

[nautilus7]

@ earl

1. Probably wine. Wait until madshi shows up to be sure.
2. Read here.
3. A few posts above is your answer... eac3to can delay all audio tracks. Only exception is truehd demuxing (the delay value is written to the filename then). You don't to do anything in mkvtoolnix.

@ odin24

Post the eac3to log file. Probably surcode didn't start encoding (the processing time is too short).

@ bigdog660

It doesn't have to do anything with the codecs installed (-test) - these are for decoding/encoding, not reading the source files. Perhaps it is caused from bad ripped discs. Did you got all these errors in one day? Can you find a disc that works to ensure that it's not your system's problem? Can you send a sample from one of those movies to test it?

[ntk]

Hey folks, is BDEdit (or similar manual approach), and then entering each .m2ts filename on the command line, still the only way to figure out and then select which files to include for a branching disc?

Or is there an automatic way to select which .m2ts files to include in my "eac3to 00001.m2ts+00002.evo movie.mkv" command (e.g. if I could just specify a playlist file that would be pretty cool!)

[nautilus7]

eac3to can read playlist files and find the correct order automatically. Just run eac3to and set as input the root folder of your blu-ray disc. Then select the appropriate title { 1) or 2) or 3) or... } and add it to the previous command line.

[mochevolete]

sorry for the n00b question, but in what circumstances vc1conv must be used ?

[Beastie Boy]

Preparing video to make BluRay, or for creating WMV files for playback on XBox 360.

Cheers, Beastie.

[mochevolete]

ok, so my "normal" usage for eac3to will be Blu-ray / HD-DVD to mkv, in this case I won't need it.

thanks, Nik

[nautilus7]

And also the pulldown removal in eac3to is for the same purpose, but as madshi have said latest vc1conv does a better job. That's why he had removed that functionality from eac3to (he put it back by request).

Can you type in an example command line to do that, I tried that the other day and didn't have any luck. I'll try it out this afternoon when I get home. I like tsmuxer, but eac3to has seemed to always give me better results.

One other question, will eac3to demux m2ts files and produce a raw 264 file?

Yes, sure. First type this command to get the available titles:

Then add the title you want to the previous command:

eac3to "F:\Rambo IV 2008 Blu-ray 1080p H.264 DTS-HD MA 7.1" 1)
M2TS, 2 video tracks, 3 audio tracks, 2:00:22

6: AC3, English, 2.0 channels, 192kbit/s, 48khz, dialnorm: -27dB

Last step is to select the streams inside the title you wanna process:

eac3to "F:\Rambo IV 2008 Blu-ray 1080p H.264 DTS-HD MA 7.1" 1) 1: c:\rambo\rambo.chapters.txt 2: c:\rambo\rambo.mkv 4: c:\rambo\rambo.flac 4: c:\rambo\rambo.dts -core 5: c:\rambo\rambo.comm.ac3

Yes, it can. Simply select the video stream and set .264 as output extension. Generally, it's not a good idea to demux video though, because it can lead to audio/video sync problems and other artifacts, but you can always try and see.

[EPiPH0NE]

^^^Just use Eac3to+and+More+GUI -> select 'stream' folder as input -> done. Much easier.

[nautilus7]

I wouldn't say that the command line way is difficult... plus the first time i used the gui, I was lost.

[rebkell]

eac3to "F:\Rambo IV 2008 Blu-ray 1080p H.264 DTS-HD MA 7.1"

Wow, that's the root directory, what I tried was just eac3to d: , which works great on HD-DVDs, I didn't see all the other stuff as a folder, I'll look a bit harder when I get off.

I'll probably try the gui, I was like nautilus7 when I tried the gui before, now that I've used eac3to some and am a little more familiar with it, the gui might be great, but I didn't have a clue about eac3to to start with and the gui was overwhelming.

[Yraen]

That's probably the root folder for a ripped disc. If you're running straight from your HD-DVD/BD drive then d:\ is fine.

[rebkell]

It won't work for me, eac3to d: or eac3to d:\ always comes back with the message:
HD DVD disc structure not found. I can run eac3to directly on the main m2ts file in D:\BDMV\STREAMS, but that is all it works on the best I can tell, I've tried the mpls files and that doesn't work either.

Running 2.42, ouch, I would have sworn I had 2.46. Anyway, downloaded 2.46 and now all works as it should. Thanks for the replies, I would have suffered through until a newer version was released.
