eac3to - audio conversion tool

[mochevolete]

thanks for reply, I'm making MKVs for the PC, so the "double pass" thru v1conv is useless ?

Nik

[nautilus7]

Yes, that's right.

[Momber]

I disagree. Those flags are just plain wrong and they need to go! Vc1conv processing is imperative imho, until madshi finds the time to implement the vc1conv code into eac3to.

[laserfan]

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

----------Good grief, just when I think I've been paying attention here, this comes along and I think "where the heck did THAT come from?"!!!??? :confused:

Wow, nothing about this that I can find in the /h info--if this is "tribal knowledge", how can I join the tribe, or does one have to be born into it!? :D

Re: demuxing, you said:

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.But if one needs to demux e.g. to run DGAVCDec on it, then...?

:stupid: LOL, I know, this is the greatest thing since sliced bread and it's got so little documentation about the power inside. The help file only seems to skim the surface of all the things it will do. You can use mkvextract to extract the 264 out of the mkv file, but I'm hoping to use the -demux option in the future, but I'm not sure of the syntax needed, according to the help file, it demuxes the first video track and all audio tracks.

[nautilus7]

But if one needs to demux e.g. to run DGAVCDec on it, then...?If your source is blu-ray, you don't need to demux the video. Just load the .m2ts file (although this might not work for multiple files).

Do you want to encode the video? Demux it then. Set .264 as extension to the video stream. Alternative, you can use eac3to to convert to matsoska and then build a graph file using haali media splitter --> ffdshow and DirectShowSource() to load in avisynth.

I'm not going to keep this one and HD-DVD is pretty much gone it seems but this was the first I'd ever seen such an error so thought I'd note it. Dumping this one Monday <shrug>

[nautilus7]

The 2nd screen/command takes the stream info from the .xpl file. Because of that it's quick and inacurate. It doesn't read any .evo files. When you load the evos (like you did in the 1st screen or by using title 1), 2), ...) you get the actual streams inside the evos.

So, in your case there's something wrong in the evos. Perhaps they are damaged or the eac3 streams have something different from the usual ones (that eac3to likes). Try only the 2nd evo file. If nothing changes, then it might be useful to make a sample and upload here, so madshi can take a look into it, when he show up (i guess he is too busy right now). Else, try re-ripping the disc.

[BLKMGK]

The L1 file throws errors but appears to be decoding and then errors, the L0 errors right away. IMO this is a bad authoring job - which is actually part of one of the errors I got. (lol) No biggie as this is a sort of fringe disk I think and I can get rid of it for someone with a "real" HD-DVD player to have <shrug>

[laserfan]

LOL, I know, this is the greatest thing since sliced bread...Well, nautilus7 didn't respond to my wonderment so I guess I have to consider a new theory: that nautilus7 is actually madshi "in disguise"! ;)

If you know the basics of eac3to you can use the GUI and study the command line that it makes. Yraen certainly knows what he's doing and his tool does it's job well and has all of the options.

[nautilus7]

I am following this thread (and eac3to development) since July 2007. At that point the thread was already 100 pages long --> I read them too. Don't think i am a guru or something. I am here just a little longer than others. All these commands where well explained by madshi when he implemented them in eac3to, so probably were missed by some.

[mochevolete]

Hi again, real first trouble...

from the HD-DVD Im' dealing with, I'm extracting two audio tracks, both are DD+, the first is 1536kbs the second is 768kbs, with the last one no troubles getting an AC3 640kbs (just one tenth longer), but no way in convert it to DTS 768, it stutters like crazy and it's longer by almost two minutes (!).

But I could easily live with the AC3 640 result.

The big problem is the bigger one, the 1536kbs track (always DD+) I've tried everything:
- > DTS 1536
- > DTS 768
- > AC3 640

Using Surcode 1.0.21 and .23, Sonic 4.2 and 4.3, Win Xp and Vista, the closest duration of all my attempts is 3 seconds longer than the video, most of them are from 10 to 7 seconds shorter o longer.

After almost two days of "tests" I'm a bit skeptical... :(

What am I missing... ?

You can see the WriteHeader routine in Encoder.cs from last BeHappy source code (http://www.codeplex.com/BeHappy/SourceControl/ListDownloadableCommits.aspx), with support for wav, w64 and rf64 headers. Only the header change the audio data is the same.

Fixed. However, I've still trouble with the video in both cases. The luxe video seems to be very strange. The h264 bitstream seems to have a crazy framerate stored in it. Will need to check this properly later...

wine --version
wine-1.0-rc3


[v01] Starting DirectShow conversion failed.
Aborted at file position 1409024.

in a real windows it runs fine
I've no idea why that fails. I'm not a Linux expert at all. It seems to me that Haali's filter doesn't work well in wine. It could be a bug in wine. Or maybe Haali is doing some funny stuff. There's not much I can do about that, unfortunately...

I am currently looking into MPLS parsing. What I want to find out for the time being is the m2ts files making up the playlist and to reliably detect the main movie MPLS. Do you have any information concerning that?
There is just no information available to properly detect the main movie MPLS. eac3to just lists all playlists with a runtime longer than 30 minutes (or something like that), sorted after runtime.

eac3to will not stripPullDown on HD-DVD AVC streams, only on VC-1, is that correct?
Correct. And the VC-1 pulldown stripping is only a partial strip and needs to be manually activated (via command line option).

the remuxing of the cinema paradiso blu-ray results in a problem, eac3to says "This doesn't seem to be a valid h264/AVC stream." and doesnt recognize the video stream.
Will be fixed in next build.

Q. 2. I know support of E-AC3 is optional in the BD world, I will be using PS3 to play, which I believe supports it.
BUT will a BD with a E-AC3 track only play properly more widely (eg if I was to burn to BD disc)
Or would I be better off putting both the AC3 and the E-AC3 onto the BD disc/folders
Blu-Ray and HD DVD E-AC3 tracks are *NOT* compatible (Blu-Ray E-AC3 tracks have an AC3 core, HD DVD E-AC3 tracks don't). You can not reuse HD DVD E-AC3 tracks for Blu-Ray authoring. At least not if you care about PS3 compatability. You'll have to transcode the HD DVD track to another format.

q.3 Any comments on why there are minor (probably negligible) differences between different demuxers?
There are differences. Some demuxers have bugs, others don't. Some demuxers make sure that audio is in sync, others don't. Some demuxers remove garbage data at the beginning of the demuxed tracks, some don't. Some demuxers patch audio/video tracks (e.g. removing dialnorm etc), others don't. Some fix audio overlaps/gaps, others don't.

Q4. What is best tool to give exact lengths of video and audio files, once demuxed? MediaInfo only gives to the minute for audio files
eac3to should give fairly precise information (rounded to seconds) about the runtime of the audio files it supports. Runtime of raw audio/video tracks with variable bitdepth is nearly impossible to "guess" right. A tool trying to find out the correct runtime would have to parse the whole video/audio stream to make sure that the runtime is exact.

ArcSoft TotalMedia Theatre build 113 Trial:

http://www.arcsoft.com/support/downloads/downloadnow.asp?downloadid=384

can decode DTS-HD MA including DTS-HD MA 7.1 channels using GraphEdit:

FileSource (Async.) -> ArcSoft MPEG Demuxer -> ArcSoft Audio Decoder HD -> Dump.ax

still doing tests, but initial results look very promising, i.e. decodes are bit-perfect.
@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.
Yeah, it really looks like that!! Will put that on top of my to do list.

Just a quick question. When converting DTS to AC3, using eac3to and the Sonic Audio Decoder (which takes about 9 minutes), I see only 1 of my 4 cores is being used. Does eac3to have a multi-threaded switch by any chance? I couldn't find any. Or maybe the Sonic Audio Decoder is not muti-threaded?
eac3to is using multiple threads whenever it's easily possible. E.g. if you decode two audio tracks at the same time, usually one thread is used for one audio track. The Sonic Audio Decoder doesn't seem to do multi-threading on its own. eac3to cannot force it to do that.

When demuxing a m2ts-File with MPEG2-VideoCodec the Videofile is defekt and not playing on Standaloneplayer.

The Problem ist - the Header is 2x at the beginning of the m2v-File.
Will be fixed in the next build.

When demuxing a m2ts file (extracting DTS sound of "The Matrix"), eac3to reported a 600000ms offset (10 mins). That seems a bit excessive. :) I was able to correct it again by specifying a negative -600000ms delay to compensate. But any idea what might have caused this?
Could be a bug in the m2ts file. But it could also be a bug in eac3to. eac3to v2.46 used such crazy delays if it didn't detect any valid video streams. This will be fixed in the next build.

[madshi]

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.
If an error occurs which you can skip, eac3to will tell you about the option you can use for skipping that error. A lot of errors can simply not be skipped in the current version.

what does pulldown flag mean ? what have i to do if i mux the video into .mkv ?
If you mux to MKV you can ignore the pulldown flags. They are not nice, but they don't harm much because eac3to writes proper timestamps (ignoring the pulldown flags) into the MKV file - and the video decoders only care about the timestamps coming from the container. However, if you want to demux video and mux it to another container with other tools you should better remove the pulldown flags.

"[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 ?
As long as you feed eac3to with the original container (TS, m2ts, VOB or EVO) eac3to will automatically take care of any delays. You only need to worry about the delays if you use other tools for demuxing audio.

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?
Try running the DTS stream another time through eac3to ("eac3to your.dts anothertry.dts". That might fix the problem. The Surcode DTS encoder sometimes adds zero padding to the DTS stream, which many tools dislike. eac3to will remove the zero padding for you.

Hi Madshi,

Just popped in to ask a question;

Lately i' m making some AVCHD-disk; And according to the standard the audio on those disks can only be AC35.1 (up to 640 kbps). Thats no problem, but teh standard also mentiones that the framerate for video can only be 24, 25 or 30 fps.

I' d like to ask if it is possible to implement a function like speedup is now, but only speeds up the audio to 24 fps. This way i can use EAC3to to make to convert the audio i need for my AVCHD disks, cause 24fps is closer to the original (23,976).
Are you sure that it's really 24.000 and 30.000? Often "24fps" and "30fps" is used when actually 23.976 and 29.970 is meant.

I've been converting my hd dvd's for playback on appletv with the following steps:
1. anydvd to rip
2. eac3to to obtain .mkv video file and .ac3 multichannel audio
3. mkvmerge to create .mkv container file
4. visualhub to convert .mkv to .mov file (1280x720@24fps with .ac3 audio passthru)

i've been successful with many dvd's but encountered a few "problem discs" along the way. now that i've hit my 3rd problem disc, i've noticed a trend. all three (Anchorman, TopGun, and now Stardust) have h264/avc video streams. the discs i've been successful with are all vc-1.

the .mkv file created by mkvmerge won't even play on my computer (iMac with windows XP thru parallels). Multiple mkv players (VLC, mPlayer OSX and Media Player Classic). VLC gives the smoothest video playback but the audio falls out of sync. mPlayer OSX reports a progressively increasing a/v sync that maxes out around 4 sec and a larger dropped frame rate. MPC won't even play the files at all, immediately giving some error message.

consequently, the .mov file created by VisHub as played thru the appletv has a stuttering video with smooth audio playback.

the vc-1 discs (at least 10) that i've done all work fine.

thoughts?
All the h264 HD DVD movies I've converted to MKV played flawlessly for me. However, I'm using Windows. I rather guess that maybe your Mac software is confused by the pulldown flags. You could try remuxing the video, running it through h264info to remove the pulldown flags and then muxing it to MKV.

from the HD-DVD Im' dealing with, I'm extracting two audio tracks, both are DD+, the first is 1536kbs the second is 768kbs, with the last one no troubles getting an AC3 640kbs (just one tenth longer), but no way in convert it to DTS 768, it stutters like crazy and it's longer by almost two minutes (!).

After almost two days of "tests" I'm a bit skeptical... :(
The audio doesn't have to be exactly as long as the video is. E.g. sometimes there's some scrolling info text at the end of the movie where no audio is available. Another problem is that when using DTS encoding sometimes the DTS tracks end up having zero padding in it. This confuses many DTS splitters. Remove the zero padding by running the DTS tracks another time through eac3to. That should fix that problem.

Generally don't look for trouble. Don't worry if audio and video runtimes do not match. Just play the movie and check if audio is in sync in the beginning and end of the movie. That's the only thing that is important.

Should be fixed in next v2.47, I guess. If not, please let me know.

[madshi]

eac3to v2.47 released

http://madshi.net/eac3to.zip

* improved detection of AC3/DTS tracks in TS/M2TS container
* added support for Blu-Ray style LPCM tracks in TS container
* fixed 44.1kHz AC3 tracks
* fixed crazy audio delay values when no video track was detected
* sometimes video/audio tracks were not properly detected in (M2)TS container
* MPEG2 demuxing/remuxing incorrectly output the first sequence headers twice
* sequence end codes are removed when demuxing video now, too
* MPEG2 pulldown removal is automatically activated only for EVO HD sources now
* MPEG2 pulldown removal can be manually activated by using "-stripPulldown"
* MPEG2 pulldown removal can be disabled by using "-keepPulldown"
I currently don't have much time for eac3to development. So I've just done some bug fixes for now. Maybe I'll have more time next weekend. Or not.

P.S: Most MPEG2 TV broadcasts and also most DVDs don't have a reliable pulldown pattern. As a result they work best if you don't remove the pulldown at all. Just keep them at 60i. If you're sure that your source has a reliable pulldown pattern you can force removal of pulldown - but then better check if audio is in sync with the final video/audio files. The HD DVD MPEG2 movies (which are extremely rare, though) should have a reliable pulldown, so for those eac3to removes the pulldown by default.

Have edited that post.

Have edited that post.

Yes i'm shure that it really is 24.000

I've tried making a AVCHD with 23,976; Then the audio plays, but the video isnt displayed. Only on 24 fps it works (and on all other rates supported by the format, see here: http://www.avchd-info.org/format/index.html).

The current video i'm working with is 720p @ 23,976. The player i'm trying to get it to work on is the Panasonic DMP-BD30.

eac3to 2.47 bug report:

LPCM, 7.1ch, 24bit, 96kHz track is decoded by eac3to as WAV file that is reported by players as 48kHz, but looks like only the WAV header is wrong, because eac3to reports the parameters correctly:

2: RAW/PCM, Japanese, 7.1 channels, 24 bits, 96khz

If you convert it to flac... Is it reported correctly then?

(if the wav header is written accidentally as 48 khz, wouldn't then the track played at half speed? :confused:)

thanks for 2.47, as I said Ill report back in case I should encounter problems

eac3to v2.47 released

http://madshi.net/eac3to.zip

* sequence end codes are removed when demuxing video now, too
.

So this means we dont have to mux to mkv when doing a seamless branching movie correct? Then i can mux my demuxed video and audio with tsmuxer.

Hmmmm... Could I have a small sample of the source file (m2ts or evo), please? 10MB should be plenty. Thanks!

Yes, that's exactly the purpose I implemented it for. However, depending on how tsmuxer behaves it might still be better (or worse) to choose MKV as an intermediate step instead of demuxing. My recommendation would be to test both solutions (1: eac3to -> MKV -> tsmuxer; 2: eac3to -> demux -> tsmuxer) and see which end result is better. I can't say which will be better. That depends on tsmuxer.

Thanks, will be fixed in next build.

eac3to v2.47 crashed when trying to make a flac out of this one:
www.earselect.se/test.lpcm

eac3to v2.22 can handle it though

That's a crash in the MP2 audio parser when trying to find out whether the file is MP2 or not. v2.22 didn't support MP2 yet. That's why it worked with v2.22. The problem will be fixed in the next build.

the ac3 commentary track from the patton blu-ray has a -9ms delay. but when demuxing that track eac3to writes the 'applying (e)ac3 delay...' message, which actually doesnt/shouldnt happen in that case. if a delay was applied then the sync would be worse than no change at all, because of the 32ms frame size. so is this message in this case basically only generic even though eac3to doesnt add a delay here, its printed out each time any delay is detected, indicating to the user that eac3to looks to solve this issue automatically, even when the solution is not adding a delay at all?

Latest eac3to version crashes with title 1 (main movie) of National Treasure 2 Blu-ray. I think this is because of the PiP function (secondary video stream) of this disc. Previous version simple couldn't detect the dts track of the secondary video stream.

Getting the same sort of error with Jumper :( How exactly did you create the bugreport file? Vista is offering to send it off someplace but umm yeah I dunno' know where :rolleyes: If I view the bug report I see the access violation etc. but no way to copy that data out... DYING to see this movie lol

[nautilus7]

...but umm yeah I dunno' know where :rolleyes:
That's why newer versions of eac3to copy the bug report to the folder that eac3to is located. :p Jumper has PiP as well.

I got the same crash/error on Jumper with 2.47 (with the newest AnyDvd update). I was able to successfully process it with 2.46 and so far (about 1 hour in to watching it) everything's looking good.

I processes NT2 with 2.46 also and had no problems other than that DTS error message. My output video/audio streams were just fine.

[nautilus7]

I noticed that Rambo (2008) blu-ray which uses PiP also doesn't crash with 2.47. Although the PiP audio track is AC3.

Just checked the source code. The text "applying (e)ac3 delay..." is always shown if the delay is not zero. But a delay is actually only applied if it's at least half of an audio frame. I'll fix this in the next build. The text will then only be shown if delaying actually changes something.

In other words: It's only the text that is wrong. So no need to worry...

Latest eac3to version crashes with title 1 (main movie) of National Treasure 2 Blu-ray.
Getting the same sort of error with Jumper :(
Could I have a small sample of National Treasure 2 and Jumper each? Of course that helps only if the problem also occurs with the sample. The sample doesn't need to be big. Even 5MB is enough, as long as the crash also occurs with the sample.

Thanks!

I have a TS file with a h264 video stream and an ac3 5.1 audio stream.

When processing it with eac3to 2.46 gives this message:

Can't we process TS files with other than MPEG2 video streams?

The h264 and AC3 tracks are detected just fine. So I see no reason why eac3to shouldn't be able to handle them correctly. Just give it a try.

The complaint is about an MPEG2 video track, which is not listed in the track listing. I think that there is probably a 3rd track (besides the h264 and AC3 tracks) which eac3to cannot handle properly. If you want me to look into this problem, I need a little sample of this file. 10MB should be enough.

Does eac3to handle standard definition DVDs like blu-ray and/or HD-DVD or do you have to combine all the vob's on the command line?

Currently eac3to is not as comfortable to use for standard DVDs as it is for Blu-Ray and HD DVD. That means you have to write down all the vobs to the command line manually. This may change in a future version.
