Many thanks madshi for the update--your attention to detail is VERY MUCH APPRECIATED!

I just get an error message like this:

What would that switch do exactly?


[/QUOTE]

Some rare CDs have pre-emphasis. Extracting them in secure mode with EAC leaves the file emphasised. eac3to could have a switch to
get proper gain figure at high frequencies when processing the wavs.

WaveEmph110 does the job, but a switch in eac3to could be a nice feature, although rare.

Glad to see you back in action madshi.

Small feature request while you're still around. Would it be possible to add a -down7 switch that makes 6.1 channel output from 8 (7.1) channel soures?

[StephenB]

Can you please post a full eac3to log file (in "[ code ] [ / code ]" brackets, please)?

This is from a script that automatically called EAC3TO again if it detected a gaps file

Welcome home madshi!

I'm trying to serve a live 16-bit 44.1 FLAC stream via Tribler, but so far, so stumped. Tribler uses Python to convert live input (FLAC in my case) to .mpegts, but thus far, none of my .mpegts output is readable. There is one thing I should mention about the FLAC I use as input: VLC can play it as a live stream (from another instance of VLC) but foobar2000 can only play it once it has been saved as a finished file.

Any tips on how to proceed? madshi, especially would appreciate your weighing in here.

How do you know that? You could try pressing "Ctrl+C" when the 2nd pass starts. Depending on how the 2nd pass is executed, this might get you what you want. Eventually eac3to has already deleted first pass results, though. Depends on the circumstances...

Eac3to says there is an audio delay of 600ms after the discontinuity. After the second pass, eac3to should have corrected that, so audio should be in sync. However, it is not, it is out of sync by something that looks like approx. 600 ms.
So I conlude that if eac3to had not "corrected" the "delay", it would still be in sync.

I was going to try Ctrl+C, but I thought I would ask first because I don't like it. Maybe I'm too late and the files are already changed and might not work any longer.

I assume it would be easy for you to add an undocumented switch "-no2pass" or similar.
If it means a lot of trouble for you, please forget about it.

I'm confused about the handling of Dolby Digital, Dolby Digital Plus (aka E-AC3), and TrueHD. If I encounter a track like this:

3: TrueHD/AC3, English, 5.1 channels, 48khz
(embedded: AC3, 5.1 channels, 640kbps, 48khz, dialnorm: -30dB)

and I don't want the TrueHD track, do I convert to "ordinary AC3" by using the -core option, or -640 option, or neither e.g. "eac3to 3: audio.ac3" ?

[TinTime]

Use the last option you mentioned, i.e...

I don't think there's a fixed standard on how to name these files. If there was such a standard, I'd be happy to make use of it. But as long as different encoders expect different names, I'll not adjust to one specific encoder.

It's not just one specific encoder, but the encoders written by DTS and Dolby (both of them). There is a fixed standard on how to name the files in the DVD/Blu-Ray industry:
For 5.1:
L, R, C, LFE, Ls, Rs
For 6.1:
L, R, C, LFE, Ls, Rs, Cs
For 7.1:
L, R, C, LFE, Lss, Rss, Lsr, Rsr

All capitals are acceptable. These are the extensions that are printed on the labels of the tapes delivered from the studios to be encoded for Blu-Ray. These extensions are also used by the two professional audio encoding suites: DTS-HD Master Audio Suite Encoder and the Dolby Media Encoder. You can see both of these encoders expecting these extensions here:
Dolby:
http://www.dolby.com/professional/pr...ng/DMP_02.html
(Click on the image to make it bigger)

DTS:
http://www.dts.com/Pro-Audio_Softwar...D_Encoder.aspx
(Again, click on the image...)

These two pieces of software will auto-fill the WAV files when you select one if the file names are correct.

That's the only reason I mentioned it... People keep reversing the letters, or in some cases, use completely different letters, and it can get confusing sometimes...

Again, it's not really a big deal (there's probably more imortant things you have to worry about)... It's not like it's hard to rename the files. I was just making an observation...

[kypec]

Hello madshi,
any chance you could put the most recent version of libFLAC.dll in your package at next release? Just for the sake of having up-to-date libraries included with eac3to.

You are free to name the channels inside DD/DTS, but still the channels are in wav format you must use the wav names and order:

Front Left - FL
Front Right - FR
Front Center - FC
Low Frequency – LF
Back Left - BL
Back Right - BR
Front Left of Center - FLC
Front Right of Center - FRC
Back Center - BC
Side Left - SL
Side Right - SR
...

I've been pulling some of my older DVDs to disk for storage on my server. Being a user of EAC3TO for HD-DVD and BD, I was trying to stick with a similar process. Does EAC3TO do "joined VOB" correctly?

command line: eac3to.exe VTS_01_1.VOB+VTS_01_2.VOB+VTS_01_3.VOB+VTS_01_4.VOB+VTS_01_5.VOB+VTS_01_6.VOB 2: movie.m2v 3: movie.ac3

The info returned identifies the source as a "joined VOB" but the the total length is way off and I often get errors such as large gaps in the audio or video overlaps during the demuxing of the streams.

Am I doing something wrong or is this just not the correct way to use the tool?

No it doesn't. Currently eac3to isn't capable of reading IFO and handling SD DVDs. When or if Madshi will add support can only be answered by him.

Use DVD Decrypter.

[The_Keymaker]

I just ripped my copy of Iron Man Blu-Ray using eac3to and have two questions.

1. It appears that MKmerge does not support muxing of TrueHD audio tracks (at least the version I'm using (v 2.53) doesn't. How can I mux a TreuHD audio track into mkv? Is this possible? My audio file has the extension *.thd.

2. For playback i use Zoom Player which as you know is highly configurable, allowing me to select directshow filters for play back. Howver, I can't seem to get the Iron Man TrueHD audio track to play. In graphedit I tried using Nero File source (Async) > Nero Splitter > Nero Audio Decoder 2 > Audio Renderer. But nothing connects (yes, I renamed graphedit to "Recode"). Any suggestions on a working graph for TrueHD playback??

Thanks,

You could convert the TrueHD track losslessly to FLAC - that's what most of use do.

Flac is easy to decode, thanks to Madshi writing the Madflac decoder

Use DVD Decrypter.

Yes, definitely use DVD Decrypter and pay attention you choose only one PGC to decrypt in IFO mode. Select None file splitting as to finish with only one (rather huge) VOB file instead of many smaller ones. eac3to has (probably as many other tools) problems with multiangle VOB stuff and such. I recently used eac3to with 2 joined VOBs ripped via IFO mode (one PGC only) successfully - The Lion King 2 Special Edition.

No offense man but what has your problem to do with eac3to? Tribler seems to me as completely unrelated to HD-DVD/BD/DVD audio/video processing for which eac3to is targeted. You shouldn't put your hopes in getting fast and effective answers from the forum members when you post at the wrong forum in the first place. If you anticipate to receive help directly from madshi on your problems you better try to contact him personally via PM/IM.
If I was in a bad mood I'd say your post is nothing but violating our forum rules, especially point 12.
My advice to you is find Tribler discussion forum and try to ask for solution there.
