eac3to - audio conversion tool

[rica]

Hi. New to this tool. Worked on one DTS file but the second one threw an error ERROR: block code look-up failed
[dca @ 68A532E0]Didn't get subframe DSYNC. It seems to create an ac3 file but I can't test right now.

Also I have Arcsoft Total Media Theater installed but eac3to does not seem to realize it and won't use that decoder. It uses libav instead. Anyway to force it to work?

Try to put " - arcsoft " at the end of the line, if it insists on not working, there must be something wrong since normally it is default decoder.

I don't even see the dts dll's on my computer. I don't get it. I downloaded it from their web site. Is there something I'm mssing? When I look at the about it says Total Media Extreme version 1.0.6.31. Do I have the wrong software?

FWIW, even though eac3to threw those errors it seemed to produce a listenable ac3 file.

Could be a PATH issue, this thread talks about it: http://forum.doom9.org/showthread.php?t=139946

I think you used TMT trial first and after it expired you installed TME, correct?
Firstly uninstall TMT and restart and reinstall TME again; i think it's gonna work for a while :)
EDIT: Arcsoft gives you 42 day trial time by TMT+TME, btw:)

[cg1200]

I found the proper dll's. They were hiding in a different location. I got a little further - it seemed to recognizt arcsoft but then bombed immediately:

I have TME 1.0.6.31 trial installed. I just tried to convert a dts file I found here: http://www.kellyindustries.com/sounds.html
Specifically the file named dts_the_other_side_48khz.dts , its about half way down the page in the DTS 48Khz section.
I have "C:\Program Files\Arcsoft\TotalMedia Extreme" in the PATH environmental variables in system properties.

@Madshi:

When you use libav/decoder to decode a german/english track at the SAME time from TWO TrueHD or TWO RAW/PCM
Tracks, the encoding is often distorted/defect. I found this problem on a few machines.

When i decode the RAW/PCM streams from the german Blu-Ray "The Pursuit of Happiness" the result is broken.

When i decode one Stream after another, all is OK. Same happens with TrueHD very often.

I think it´s better to disable the use ob libAV with more then one instance :(

[deathlord]

I could probably do that, but I don't really like the idea to add such complicated workarounds for clear bugs in a specific decoder which is still being worked on. Maybe ArcSoft will fix that problem sooner or later? You could report it to their support forum...

That sounds reasonable. I will report it to their forum if somebody can point me to some samples showing this problem.

I don't see why that should be the case. In my tests the Blu-Ray 6.1 tracks decoded perfectly fine with ArcSoft (as I already said earlier).
I meant because of the wrong volume in the back channels when decoding to 7.1, but now you have changed this:

Just noticed that I forgot to add something to the changelog:

* option "-no7doubling" is not supported anymore
* option "-double7" added which upconverts 6.1 to 7.1
So by default 6.1 tracks are not upconverted to 7.1, anymore. You have to manually activate that if you want upconvertion. Also doubling the 7th channel now also halfs the volume of the 7th channel. Which is what ArcSoft's decoder is doing, too, when it doubles the 7th channel.

Are you sure arcsoft multiplies exactly with 0.5? Because this can't be correct, the two back speakers are not at the same position and don't radiate in the same direction, so with 0.5 they won't add to 1. Actually it should be 0.76, as I have calculated earlier (http://forum.doom9.org/showthread.php?p=1153717&highlight=tebasuna51#post1153717) using the method proposed by tebasuna51. Maybe I should report this also to arcsoft?

Don't know why. Maybe the DTS file is corrupt? Or maybe the ArcSoft installation is broken...

That would be VERY bad. Do you happen to have a short sample with which I could reproduce the problem? Two raw/pcm tracks should be no problem cause libav is not involved. Two TrueHD tracks might be a problem. Or maybe the problem is not with decoding but with encoding? Which format are you encoding to?

Are you sure arcsoft multiplies exactly with 0.5?
I said half volume, which is a multiply by 0.5^2 = 0.707.

[cg1200]

Don't know why. Maybe the DTS file is corrupt? Or maybe the ArcSoft installation is broken...

It has worked for 2 out of 3 soundtracks for now using arcosft so I think it's ok. I think maybe that one soundtrack was corrupt. even though it threw the errors it eventually did produce an AC3 file which worked with the occasional crackle through my speakers.

BTW, this is a great tool. I have been looking high and low for an easy way to convert DTS to AC3. this is by far the easiest tool and works the best. the quality is superb and it only takes a few minutes. Thank you!!

[deathlord]

Oops, sorry, I should have realized that.
Thanks a lot for the new "-double7" option.

Hmm, I have no sample at the moment :( The Blu-Ray i named before produces this problem when decoding PCM german+english at the same time to ac3 -448kbit.

I have the same problem with TrueHD, too...

Only with 2*sonic/dts -> 2*ac3/448 is working all the time.

Only when ONE file at ONE-time is encodet, the output is OK.

The Problem is not always reproduceable. Looks like uninitialized "directshow" - you know: never hope that windows can made more then one thing at the same time :)

Finaly i can say: When you made multi-audio de/enconding at the same time, ONLY Sonic/DTS works all the time.

Nero & Arcsoft can´t be used multiple, so this error never comes up here.

Looks like an directshow or threading or something-else problem...

undocumented option -progressnumbers now outputs "analyze:" and "process:"

Just a little cosmetic thing.
Every new progress percentage is shown in a new line.
It would be great if it updates in the same line instead.

maybe something like this

... other code ...
cout << "analyze/process: 0%\r";
while(!inputfile.eof()){
if (counter==number) {
counter=0; cout << "analyze/process: "<< getpositioninsource()*100/getfsize() << "%" << "\r";
}
counter++;
... do something ...}
cout << "analyze/process: 100%\n";
... other code ...


with "number" = any multiplier to the size of your readingbuffer for the inputfile

example:
show update of the percentage every 50MB
buffer = 32Kb
--> number = 1600

Hmm, I have no sample at the moment :( The Blu-Ray i named before produces this problem when decoding PCM german+english at the same time to ac3 -448kbit.
If the problem ocurred with PCM then it should also occur with TrueHD, DTS and any other format, because PCM is the least sensitive of all. The problem may be caused by the AC3 encoder or maybe by an unstable PC? Have you overclocked your PC?

I need to be able to reproduce the problem, otherwise I can't do anything.

Just a little cosmetic thing.

It would be great if it updates in the same line instead.
The progress percentage display is meant for programs which want to automate eac3to. For those programs I think it's easier to output one new line for every progress step. The option is *NOT* meant to be used by people who call eac3to directly in the command line.

Hi i cut an HD-DVD EVO including a pure TrueHD with TSRemux.
When i play the recreated file no problem.

But when i demux that created file with eac3to like this:

eac3to v2.63

i got a file renamed to "audio DELAY-761ms.thd+ac3 instead of audio.thd+ac3

No such kind of issues from demuxing source evo.

Even i add an +761ms at the and of the line and re-process with eac3to, it is still out of sync. (Even the reverse doesn't change the result; -761ms)

Don't know what to do in this case?

BTW, libav converts it to constant bitrate from variable?

eac3to cannot fix audio delays in TrueHD streams. So you need to adjust audio sync in your media player. Or when remuxing the raw streams to a new container you need to mux them in such a way that the audio tracks begins 761ms later than the first video frame. Don't ask me how to do that, I don't know. There's nothing I can do at this time. Delaying TrueHD streams is just not possible technically at this point in time. eac3to can delay all supported audio bitstreams - except TrueHD.

BTW, libav converts it to constant bitrate from variable?
That question doesn't make much sense. libav decodes the track. eac3to checks which true bitdepth the decoded data has and reports that.

[rica]

Thanks,


That question doesn't make much sense. libav decodes the track. eac3to checks which true bitdepth the decoded data has and reports that.

Sorry but i was told lossless BD/HD audio is variable bitrate and i thought libav decodes in that manner.

What is interesting; mediainfo shows this after remuxing with TSMuxer:

[nautilus7]

OMG!!! rica you 're messing bitRATE with bitDEPTH.

[madshi]

I thought he meant bitdepth. But it seems he really meant bitrate (which he correctly said). Anyway. Yes, lossless tracks have a variable bitrate. PCM has a constant bitrate. So asking eac3to to decode a TrueHD or DTS-HD Master Audio track to PCM or WAV results in converting variable bitrate to constant bitrate. But I don't really see what is so interesting about that.

[rica]

Yes i really meant bitrate :p

Yes PCM is constant bitrate :)

[nautilus7]

[a02] This audio track has a constant bit depth of 16 bitsThis is from his previous post. He has highlighted bitdepth. :eek:

[rica]

This is from his previous post. He has highlighted bitdepth. :eek:

I did say i've messed, what do you want me to say more?

[nautilus7]

I did say i've messed, what do you want me to say more?

Look at the time i posted that... Simultaneously with your last post.

This was headed to madshi, but i didn't get what he meant, thus i made that post.

It seems we all messed up. It's late EU hours. Time to sleep. :p

[rica]

Yes i realized that before you posted :)

But last thing before going to sleep:

I, this time, delayed video reverse but what happened?

Audio automatically put delay itself so nothing has changed :devil:

EDIT: OK, nautilus7 was right; with Virtual Clone Drive everything is OK after my last video delay:)

[rack04]

I was reading the eac3to wikibook trying to get up to speed on converting LPCM tracks from Blu-ray discs. Is there a bug in the LPCM parameter auto detection process because the wikibook gives two examples of the conversion to wavs?

[nautilus7]

* Convert a 16 bit 48 KHz 5.1 LPCM track to 6 mono WAV tracks, while LPCM parameter auto detection works fine:

eac3to input.pcm output.wavs

* Convert a 16 bit 48 KHz 5.1 LPCM track to 6 mono WAV tracks, while LPCM parameter auto detection doesn't work:

eac3to input.pcm output.wavs -16 -48000 -6 -little

Do you mean these? Everything works fine with the auto detection. I've never came across a pcm files which eac3to couldn't detect correctly. This is an eac3to feature... I believe it should be explained how to use it. I'll change the description a little bit.

[rack04]

Do you mean these? Everything works fine with the auto detection. I've never came across a pcm files which eac3to couldn't detect correctly. The examples are there in case eac3to can't find the pcm parameters.

Yes those are the ones that I'm talking about. Thanks for the clarification. BTW, what is the logic behind:

eac3to input.pcm input.wavs

Does this just seperate the LPCM channels into seperate lossless wav files?

[nautilus7]

Yes those are the ones that I'm talking about. Thanks for the clarification.
I edited the examples a little. :)
BTW, what is the logic behind:

eac3to input.pcm input.wavs

Does this just seperate the LPCM channels into seperate lossless wav files?Yes, plus it puts them into wav container. Don't forget that pcm is a raw format, that's why you have to somehow find what are it's parameters/characteristics. Normally this info is stored into the container, but when you demux pcm it is gone. eac3to finds them by doing some tricks. Most other programs can't.

Trying to get TrueHD track off a BlueRay disc, and then remux into BlueRay structure using tsMuxeR, then play on PS3 using the AVCHD method

Anyway I cant figure out how to get the TrueHD track to play smoothly

For example, on a BR with TrueHD track in a single m2ts, I extracted three different tracks from the TrueHD
firstly the .thd+ac3, then .thd, then .ac3


Now tsMuxeR would only accept either the .thd+ac3 or the pure .ac3

went ahead and created the BR/AVCHD structure

The .ac3 track plays perfectly using either the PS3 or a Onkyo SR606 to decode

THe PS3 is completely unable to handle the .thd+ac3 - I get silence
The Onkyo plays the .thd+ac3, but with heavy stuttering/gaps

I did the extractions using default settings

So for me anyway,I can get the TrueHD tracks out using eac3to, but I cant get them playing, at least with my equipment

Is there some setting in eac3to that I am missing?
Or is tsMuxeR up to the job?
Or are the PS3/Onkyo not up to the job


Note that the TrueHD track play perfectly (and is recognised properly) by both the PS3 and the Onkyo, if I play the original disc in the PS3

Any help appreciated

[Jeff Flowerday]

jeffnoone: The PS3 will only play TrueHD, or DTS-MA etc if it's on a Blu-Ray. The only audio codecs really supported in containers being streamed or played off a hd is ac3 or uncompress LPCM. Which basically explains why the AC3 track worked for you.

You could convert the TrueHD track to PCM using eac3to to get it play in all it's lossles glory on the PS3, it's a bit of a waste of space but the only alternative.

I bought a Popcorn Hour A-110 because the PS3 was limited when streaming, but as it turns out the PCH A-110 doesn't work either. It might someday with firmware updates but no official word from them. (Besides actually advertising it as being supported)

I do DTS-MA/TrueHD -> PCM all the time for my A-100 and have been for quite some time and it really doesn't even use that much space when compared to 1080p ES video, sounds perfect, and works on EVERY BluRay player. AFAIK DD+, DTS-MA and TrueHD bit streaming are working on the A-110. I am waiting for either a drop in the PS3 price or an NMT that decodes HD audio. That would be perfect and they wouldn't have to pay the BDA just Dolby/DTS which of course by itself is a lot of cash. I guy can dream..........

A-110:
DTS-MA is working for the most part. Certain movies seem to still have issues. DD+ isn't working at all and the only TrueHD that works is tsremuxed from the original file which forces you to leave the pulldown flag in. TrueHD rebuilt via tsmuxer won't work even if sent through tsremux afterwards.

Either you're doing something wrong or the mods over at the NMT forums are lying. Werner, has said that 7.1 DD+ from BluRay not HD-DVD is working and several others have said that TrueHD from both BluRay and HD-DVD works just fine. Either way doesn't matter for me, I'm happy with my A-100 and don't need HD audio bit streaming I need decoding.

EDIT:

I see VC-1 + TrueHD BluRay's aren't working right. I could probably fix that with Scenarist.

Anyway, sorry for the OT!

[magic144]

hi all,
just come across this issue of audio gap detaction with BD discs with branching or what have you

just wondering,
if I run a cmd like
eac3to L: 1) -demux

and then it creates .gaps files and asks to rerun the same command line,

does that imply that it would be better to run a much more specific command line in the first place (i.e. audio processing/output only) to avoid having eac3to churn through the huge video stream all over again... OR... will running this same command twice do something different with the video on the second pass as well???

thanks a lot!

When running eac3to, it prints out these examples:

Examples:
eac3to source.pcm destination.flac
eac3to source.thd destination.flac destination.ac3
eac3to source.evo 1: chapters.txt 2: video.mkv 3: audio.flac 5: subtitle.sup
eac3to feature_1.evo+feature_2.evo movie.mkv
eac3to blurayMovieFolder movie.mkv

This might be pointless for experienced users, but for newbies it's a bit confusing: A newbie might not even realize that this application is capable of much more than that, it's capable of listing the titles on a disk - just run it on the mount point of the disk or the "drive letter" - let's say drive E, and it will give you a list of titles, complete with durations so you can identify the main title:

ec3to E:

Also, it can offer a complete list with all the tracks (video, audio, subtitles) in a title. Just indicate which title you want - let's say title number 5, and it will give you a list will all tracks in the title:

eac3to E: 5)

Finally, it can extract video, audio and subtitles tracks, while following seamless branching if needed. Let's say the previous step indicated that the video is track #2, the audio we want is track #4, and the subtitles we want are track #8. In that case, extraction works like this:

eac3to E: 5) 2: video.mkv 4: audio.ac3 8: subtitles.sup

It takes a while to figure out these features when you're not familiar with the application. Please add some indications to the help text that these features are available.
Based on the existing help, a newbie may be led to conclude that eac3to is purely an audio extraction tool, which is far from truth.

[fib0by]

Bug: the video track in one title is not detected correctly. See how it's initially detected for title #2 when I run eac3to on the entire disk backup, but then when I run it only on the title number 2, or only on the 00076.m2ts file, it's not detected:

The 00076.m2ts file is played just fine, image and sound, by Windows Media Player.
If I open the file with tsMuxeR it detects the video track just fine. Extracting video, audio and subtitle tracks with tsMuxeR works fine.

Title 3 on the same disk is detected correctly by eac3to and I can demultiplex it just fine.
Title 1 is detected correctly. I haven't tried to demux it because I don't need it.

Let me know what do you need from me to troubleshoot it.

[madshi]

OR... will running this same command twice do something different with the video on the second pass as well???
If no gaps are reported for the video then eac3to doesn't do anything different with the video in the 2nd pass. So you could use a more specific command line to redo only the audio tracks with gaps in them. But honestly all you're saving is a few minutes worth of time.

It would be very nice to get a sample of 76.m2ts (first 50MB, if possible). But before you upload that, please check whether you can reproduce the problem with the 50MB sample. Thanks!!

[magic144]

thanks madshi...

and presumably several GB of repeated and unnecessary disk I/O?

who knows how much we want to thrash HDDs these days... since they're now 1Tb big, raking them might upset all the eggs I have in this 1 basket :-)

so you're also saying that sometimes there are video gaps that are tidied up in a subsequent pass too... (if so reported)? I did not know that, if that is also the case

Aparrently I did. It's extremely rare, though, at least with Blu-Ray and HD DVD.

I got problems with processing the constantine hd-dvd:

"The format of the source file could not be detected"

sample (http://ultrashare.net/hosting/fl/448cdb9334/CONSTANTINE.test) (evo, 9 MB)

any help is appreciated :)

(I'm using latest eac3to)

I wonder how you extracted this evo?

I'm having trouble converting the DTS-MA to ac3 from the 28 Days Later Blu-ray disc.

Am I missing a step (I don't have ArcSoft so it's using Sonic) and I do:

eac3to "pathToProperM2TS" 6: -640 28DaysLater.ac3

It says:
"The ArcSoft decoder doesn't seem to work, will use Sonic instead."
"Extracting audio track number 6..."
"Decoding with DirectShow (Sonic Audio Decoder)..."
"DirectShow reports 5.1 channels, 24 bits, 48khz"
"Encoding AC3 (with libAften)..."

And then it hangs, the indicator stops blinking, the eac3to process pegs the core it is using, and nothing happens.

I currently don't have ArcSoft either, so when I want to convert DTS-HD to AC3, I first extract the DTS core. Then I run the core file through eac3to to get the AC3.

Yeah, it's an extra step, but it only takes a few minutes, and it has always worked for me.

Oh. Makes sense. Thanks!

I have this HD DVD. If you're still having problems I could rip it and give it a go. Just let me know.

[Duppie]

I just want to confirm if some of you also have this problem. Now and then I retest new eac3to versions to see if all is still OK for me. So, I always follow the same procedure to backup my BR movies but with eac3to version 2.63 there seems to be a problem with the PCM conversion. I have followed the same procedure with previous versions (2.57 and 2.59) and it always worked. What I do:

Converted BR audio track (TrueHD) to PCM: C:\eac3to 0001.m2ts 4: E:\audio.pcm. Obviously track 4 is the TrueHD track. Run PCM track through Pcm2Tsmu. Multiplex video and audio to Blu-Ray structure.

When played the sound is a bit fast forwarded and there is a lot of noise, weird sounds and cracks.

Any ideas? Am i doing something wrong? If I could assist in anyway to resolve this please let me know.

You don't need an extra step.

eac3to source.m2ts x: target.ac3 -libav

eac3to automatically extracts dtscore from DTS-HD track, decode it with libav and encode to ac3 in one step.

Ah nice, thanks for the tip!

Trying to convert the DTS commentary tracks on the Shoot 'Em Up Blu-ray. DTS is extracted properly and is played fine with ffdshow (libdts), but when I use eac3to to convert it to WAV using libav the end result is horrible.
