eac3to - audio conversion tool

[rack04]

eac3to crashes with the following file.

[Atak_Snajpera]

It does not crash on my PC.

It does not crash on my PC.

Are you using Nero 7 to decode? I don't have that installed on my laptop so I'm wondering if it is a crash in libav.

I converted M2TS video file to MKV video file with Eac3to as backup. But now i want to convert it back to M2TS container. I tried to extract MKV file, it gave me Video File in AVI Container. Can you tell me how to further extract Original VC-1 file from AVI container?

Sehgal

[EPiPH0NE]

^^^^

Just do MKV -> M2TS via tsMuxeR :)

@EPiPHONE
Got it bro, thanks very much. I was banging my head in google for AVI demuxer.
Thanks for saving my time & my head :D

Hi guys,

What kind of option should i put to command line to force eac3to use another encoder than the default?

Thanks!

See the first post.

-sonic/nero/... force the use of a specific decoder (not recommended)

[rica]

Sorry but i think i told "encoder" not "decoder"

Or do you mean i can use the same option for encoder as well?

Sorry my fault. Don't think you are able to specify another encoder.

I tried your suggestion.. Actual VC-1 & MKV file got 61056 video frames but when demuxed with TSMuxer it contained 122108 video frames.

Can you guess why is that??

I have no idea...I thought your final step was M2TS...if your looking to demux the MKV I would suggest MKVextractGUI. I don't trust tsMuxeR's demux features for MKV's.

[sehgal.v7]

@EPiPHONE
Sorry i think i used wrong Term. My final step is M2TS only. When i added MKV file into TSMuxer, it copied VC-1 stream into M2TS container but actually it doubled video frames and duration while file size remaining same. I didn't demuxed MKV file.
The thing is i took a backup of Blue Planet with Eac3to into MKV file, but i lost my original blu ray. Now i want to make another blu ray disk, that's why i wanted original VC-1 in M2TS container.

Hope i clarified this time. :-)

It looks like rica is on to something. I only use the MKV remux feature for remuxing my scene DTS/MKV's -> TS for proper playback on my NMT and I never have problems like you guys are having. I would try using MKVextractGUI to take out the VC-1+audio then put those raw streams into tsMuxeR and mux -> M2TS. Try that and see if it still gives wrong frame size. Other then that I'm stumped.

[rica]

sehgal.v7,

If you are trying to remux the mkv-vc1s made by yourself ,with an any application which uses Haali multiplexer, into a ts or m2ts container via TSMuxer, i have just one word for saying: forget it.
Just demux to VC1 with TSMuxer or eac3to and remux back to m2ts or ts with TSMuxer.
(as i told on the link i gave before)

But if you are trying to make a TS/m2ts file from a premade mkv including a VC1 and created by Haali based application,
again you have no chance.
If you are lucky -if mkv has not been trimmed before- , the only chance is to re-encode it to h264 with MeGui or something else.

[sehgal.v7]

@EPiPHONE
I took a backup of Blue Planet by Eac3to - eac3to 0000.m2ts 0000.mkv // now when i extract MKV with MKVextract.exe, it gives me an AVI file for video stream. It doesn't give raw VC-1 stream.

@Rica
I made MKV file with Eac3to// i think it uses Haali Multiplexer. :-( Means i have re-encode it// i put file in MKV container because it save around 13% space than M2TS container.

[sehgal.v7]

Did some homework.
Eac3to (with help of Haali Matroska Muxer) first put raw VC1 into AVI container then into MKV container. The "WVC1" fourcc is applied in AVI container. Players now uses MS VC-1 DMO decoder for decoding it. Now the main thing is extracting original raw VC1 from AVI without "WVC1" anywhere in it, so that we can use it in TSMuxer. I think Haali Matroska Muxer is using same pattern as VC12AVI does.

I just encoded a TrueHD stream into FLAC and eac3to reported 16 bits, yet the file itself contains 24 bits, and I'm pretty sure that's what the original source has. Here's what I get:

Constant? I thought TrueHD was variable-based. The file I get has 24 bits variable... Could this be just an error in bitdepth analyzing in this new version ...?

Backup all your HD movies with Eac3to to MKV container. Follow this routine for VC-1 files:-
1. eac3to 0000.m2ts 0000.mkv
2. Extract AVI file with MKVExtract (needs mkvtoolnix).
3. Then extract raw vc1 stream with Yamb (needs MP4Box).
4. Then raw VC1 with TSMuxer.

Thats all// verry happy to get back original streams.

@madshi

Okay, in addition to my previous post: I was wrong, the original audio does contain 16 bits (the movie is The Counterfeiters by the way) I tried it with a previous version of eac3to, and here's what I got:

eac3to v2.51
command line: D:\try\eac3to.exe 00131.m2ts 4: Another.flac

[a04] This audio track contains only 16 bit of information.
[a04] The zero bytes were successfully removed.
Video track 2 contains 142296 frames.
eac3to processing took 32 minutes, 17 seconds.
Done.

So, this end file DOES have 16 bits of information, but the one I got from 2.57 has 24, even though the difference between the two is just 1MB, which means that it was just encoded wrong, right? Or is it because of those 0 bytes? Either way, this should be fixed, pls look into it. :)

[sehgal.v7]

@73ChargerFan
I want a backup as well as i want them to play too :-) // in mkv container u can add flac audio (loseless codec). Means backup with no quality loss + whenever you want again burn your blu ray writer // your original stuff (choice of wanted audio tracks + subtitle tracks).

PS - Don't forget to backup Chapters file from original movie (if you want chapter support later).

Thanks all you guys for your kind info.

[madshi]

I can confirm that subtitle problem for seamless branching, when I remux close encounters (CE), then the length of the whole movie is 2:14:17 with last spoken line at ~2:13:24. for the non hearing impaired english subs though this line is at 2:02:17, which is much too early, while the same line with hearing impaired english subs ist located at 2:06:21, which is different and still too early.
Thanks, I'll recheck that.

When doing the Doomsday Blu-ray, I noticed that the playlist view showed DTS-HD (secondary) even though selecting that playlist shows it as being DTS Express.
It's one and the same thing. I'll replace the "DTS-HD (secondary)" label with "DTS Express" in the next build.

I think you're right. I did a test...it muxes the track, but the playback seems problematic. But if tsMuxer improves in the future, it might still be a handy option to have in your program, although it would be rarely used offcourse.
Just let me know when tsMuxeR supports proper TrueHD muxing, then I will look into adding support for creating/handling Blu-Ray style TrueHD+AC3 tracks. You should be aware, though, that the TrueHD and AC3 streams have to be muxed with slightly different parameters, so I'm not sure if tsMuxeR will actually accept a combined file. I rather guess it will expect two separate files. But it makes no sense to speculate about that right now.

I think q=0.5 as default is too big. The encoded files are even bigger than the source for some inputsstreams (at least for AC3-5.1)
I was even thinking about choosing a higher default than 0.5. But since 0.5 is the default of the command line encoder, I thought I'd leave it at that. I've no plans to lower the default right now. The default for AC3 encoding is 640kbps, btw.

I don't know the exact final matrix used by madshi.
I'm using:
Lt' = FL + 0.707xFC + 0.707xLF - 0.866xSL - 0.5xSR
Rt' = FR + 0.707xFC + 0.707xLF + 0.5xSL + 0.866xSR

However, it's not *exactly* 0.707 and not exactly 0.866 because I'm using integer math. So the real factors are slightly higher. I might change that in a future version, but I need to implement full support for floating point samples through the whole audio chain first...

eac3to crashes with the following file.

ftp://mplayerhq.hu/MPlayer/samples/HDTV/Hellboy.ts
The crash is caused by the h264 track having no frame rate information in it. I'll fix that in the next build. Not sure yet how to properly handle such a file, though.

What kind of option should i put to command line to force eac3to use another encoder than the default?
There's only one supported encoder for every supported output format. You choose the encoder by defining the output file extension.

Yes, there seems to be a bug. It's not really a big problem. The FLAC you got just be just fine. But I'll fix it nevertheless, of course.

Has anyone here tried working with Harold And Kumar Escape From Guantanamo Bay? It's a nightmare! There are over a dozen title sets to choose from. Apparently there is a feature in this disk that interactively allows you to change the plot at different scenes.

High-Def Digest:

http://bluray.highdefdigest.com/1173/haroldandkumarescape.html

"Dude, Change the Movie!" - One very cool feature, this is only the second "interactive storyline"-type function to appear on a Blu-ray (at least to my knowledge), following last year's 'Return to House on Haunted Hill.' Activate "Dude, Change the Movie!", and at pre-selected points throughout the movie (nearly a dozen in all), your given a prompt with different choices allowing you to effect the direction of the narrative. Some of the options are simply silly (at one point, you can switch the movie's "bottomless" party scene to a "topless" one, for you T&A lovers), while others are more substantial, introducing new subplots not in the final cut. I was surprised at the wealth of new material shot for this feature, and it really is like watching a different movie depending on the choices you make. Really fun stuff.

Am I going to have to remux every one of the title sets in the hopes of finding one which is unadulterated or is there an easier way to find out which is which?

Edit:
I think that this movie actually can't be backed up without keeping the entire disk intact. It seems as though every title set has these "dude, change the movie" screens in them where the movie is paused for several moments allotting the viewer the time to decide if they in fact want to change the movie.
Nightmare.

Something strange - I downloaded the latest version of eac3to last night form the link on the first page, and my antivirus (ZoneAlarm Security Suite) is now saying that there is something fishy with the hooksurcode.dll and there is an infection (Backdoor.Win32.Hupigon.dgde) so I cant extract the contents of the rar file without it quarantining the hooksurcode.dll file

Has anyone else found this? I've never had a problem before and I seriously doubt this is something Madshi has done
Kind of annoying though having to close ZoneAlarm

Anyway - big thanks to Madshi, eac3to just keeps getting better and better :D

[73ChargerFan]

Kaspersky flags that also. IIRC, ZoneAlarm includes Kaspersky as its AV. I haven't updated my eac3to in a few weeks, so it must be a new addition to the av definitions file.

I added that file (without the path) to my trusted zone. I CAN TRUST IT, RIGHT??!!! :rolleyes:

[~bT~]

^ avg used to flag it so i uninstalled it. nod32 doesnt :)

How about watching the output until you see 3 dashes '---' then count them and divide by total. I think eac3to always outputs the same number of dashes.

[73ChargerFan]

sehgal.v7,

Why not opening a seperate topic on mkv+vc1 and we can discuss there?
Please, lets.

My target is mkv (h264/vc1) & dts & flac but I can't get vc1 from m2ts into the mkv correctly. They all result in stuttering, stalling and an inability to seek or fast forward.

Madshi would like to read hxxp://article.gmane.org/gmane.comp.multimedia.matroska.devel/3397/

@TO ALL MEMBERS
Backup all your HD movies with Eac3to to MKV container. Follow this routine for VC-1 files:-

4. Then raw VC1 with TSMuxer.

Thats all// verry happy to get back original streams.

Your post looks like "how to put vc1 into ts" not into mkv. I don't know why you have to go m2ts -> mkv -> avi -> vc1 when eac3to can do m2ts -> vc1 directly.

BTW, what splitter/decoder are you using? I test my files with gabest & haali splitters, mplayer-hc, coreavc and the microsoft decoders. Nothing works.

[saint-francis]

^ avg used to flag it so i uninstalled it. nod32 doesnt :)

Nod is one of the more sophisticated AV tools. If you must use one nod is a good choice. Symantec seems to be good too. Many of them just throw up false positives when they encounter something they don't understand.

[73ChargerFan]

Is there any hope you'll open source the code?

No.
I ask out of fear that something will happen to prevent future updates and improvements. DvdDecrypter was killed by industry, tsMuxer looks abandoned by roman for now, and mommyman has just quit DVDAExplorer. The last was opensourced, so I've got hope that it can be finalized by someone else. Also some developers need a break, have children, go into the military, etc., and if it is open source someone else can pick it up.

Your expertise and time have made eac3to the most valuable program that I use, and I appreciate all that you do. I won't bring this up again.

[lexor]

The last was opensourced, so I've got hope that it can be finalized by someone else. Also some developers need a break, have children, go into the military, etc., and if it is open source someone else can pick it up.

That almost never happens in real life though. When OSS project dies, other people tend to start their own projects to replace it (if it was useful). It is extremely rare for someone to pick up a dead OSS project.

But eac3to is unlikely to have the same fate as DVDecrypter, because it doesn't actually get movies from your disc, it doesn't strip any drm. eac3to is in the clear, the same way as the burning engine of DVDecryper was in the clear and went on after DVDecrypter got shut down and is now ImgBurn.

On the subject of ImgBurn, that app is awesome enough that I haven't bothered installing the bundled pile of garbage that is Nero suit. So madshi, how should we interpret that note about ArcSoft ac3 and TrueHD decoders? It says "not yet", but will it be supported? Is there any quality concern you have with ArcSoft's Dolby support (like range compression/etc) or something else? Now that I've got arcsoft going, I'm kind of eager to get it to be my all-in-one decoder.

[saint-francis]

Look at MeGUI. Doom9 started it and now it's still pretty well maintained by other people and he isn't involved with it's development at all as far as I can tell. If some OSS is really desired and the developer stops working on it, from time to time others do take it on. FFDShow is another great example.

[saint-francis]

I found the proper, plain old normal movie in the Harold and Kumar BD. It's title set # 10 for anyone who comes after me. And yes, I remuxed the 9 previous title sets before I finally figured it out. Took me about 4 hours. :shakeshead:

[madshi]

I can capture progress in my app.
Ok, I could add an undocumented option which outputs one extra line with a progress number for each percent increase. That should make it easy for you to grab the progress.

Something strange - I downloaded the latest version of eac3to last night form the link on the first page, and my antivirus (ZoneAlarm Security Suite) is now saying that there is something fishy with the hooksurcode.dll and there is an infection (Backdoor.Win32.Hupigon.dgde) so I cant extract the contents of the rar file without it quarantining the hooksurcode.dll file
Most probably a false detection. I'll contact Kaspersky about this. Please complain, too. The more people complain, the better...

My target is mkv (h264/vc1) & dts & flac but I can't get vc1 from m2ts into the mkv correctly. They all result in stuttering, stalling and an inability to seek or fast forward.
"eac3to BluRaySource movie.mkv" seems to work well for almost everyone. Personally, I've remuxed at least a dozen Blu-Ray VC-1 movies that way and they all work perfectly fine for me. I think the problem is probably not in your MKV files but rather in your DirectShow playback setup (source filter + decoders + renderer etc).

how should we interpret that note about ArcSoft ac3 and TrueHD decoders? It says "not yet", but will it be supported?
I've not much motivation to support the ArcSoft TrueHD decoder since the free libav TrueHD decoder seems to work perfectly. I might support the ArcSoft (E-)AC3 decoder sooner or later. But adding support for the ArcSoft decoders is rather painful compared to e.g. Nero. That's why I'm only supporting the most important one (DTS) right now.

[Atak_Snajpera]

That should make it easy for you to grab the progress.

What are the requirements for eac3to to detect a folder as a Blu-ray? I know for HD DVDs its VPLST000.XPL (and then HVA00001.VTI), but that doesn't really apply here. :p

Don't know. Maybe the video data is stored slightly compressed (start codes shortened). Or maybe the last video frame is missing. Either way there's no reason to worry, as the last few frames are usually totally black, anyway.

Can you add an option in demux command to, not to demux TrueHD & AC3 seperately?
What would that be good for? TsMuxer doesn't properly mux TrueHD tracks, anyway.
