eac3to - audio conversion tool

[madshi]

The Nero HD-DVD/Blu-Ray plug-in isn't even available anymore, so I'm not sure how people who didn't buy it during the relatively short window it was for sale would get it.
I don't know. You could try contacting Nero support. But the libav decoder works well enough, too, so it's not really all that necessary to have Nero working.

As for the Arcsoft plug-in, I'm not sure which of their programs this one comes with, however I haven't heard great things about their software so I wouldn't really want to pay for it anyway.
Well, it's your choice. Either you want DTS-HD decoding or you don't want it. If you do want it, Arcsoft is the best choice. The DTS core can be decoded by eac3to without needing any external software. But obviously decoding only the core means that you don't get full quality. The core quality is very good already on its own, though.

And Surcode's DTS plug-in is ridiculously expensive.
Then just use AC3 encoding instead, which doesn't need any external software.

there seems to be a problem introduced in 3.13. The output audio is corrupted when the input file is a wav.
Argh, thanks. One of the bug fixes fired back.

[madshi]

Couple of things to notice:
32-bit and 64-bit floating point WAV files made with Audacity crash eac3to.

[...]

Notice the repeated sound in the beginning.
Should be fixed in next build.

All the FLAC files have differen't sizes and aren't identical to test3.wav.
That is expected behaviour due to dithering. test3.wav is 32bit which (AFAIK) the current libFlac encoder does not support. So eac3to has to dither down to 24bit.

does the case that gaps/overlaps of seamless branching do not exist any more apply to all kind of audio tracks? Im sure for flac, as flac framelength is only 1ms, but does this also apply to the other formats? would a DTS track created from a seamless branching movie have more gaps or overlaps in between as a flac track created out of the same movie?

[madshi]

Sorry. Interlaced, of course! And my post was indeed about a VC-1 clip. If you can detect/identify the messes that are these hybrid VC-1 clips, you will join neuron2 as the only who's figured these out AFAICT.
I was not aware that there are "hybrid" VC-1 clips. Do you mean that some parts of the clip are encoded interlaced and some progressively? Can I have a sample of such a clip, please? What kind of output would you expect from eac3to for such a clip?

As soon as you transcode audio, delays and audio gaps/overlaps are removed down to 1ms granularity. So if you e.g. convert a TrueHD track to DTS, you get 1ms granularity, because eac3to has to decode, anyway. If e.g. the movie track is DTS and you want to avoid transcoding by keeping it as DTS, then eac3to has to live with the frame size limitations. E.g. for DTS a frame is usually 10.6ms long, so delay and gap/overlap fixing is done with up to 5.3ms granularity. But don't worry, eac3to is clever enough to not let the granularity "problem" make seamless branching audio go out of sync. Gap/overlap fixing remainders are cumulated and treated correctly with every new gap/overlap, of course...

PLAYBACK 274Honestly I do not *expect* anything of eac3to, beyond what it already does correctly which is to demultiplex, and convert audio. It's just that these clips will crash most decoders, indeed AFAIK neuron2's tool is the only one that deals with them, i.e. after indexing you can re-encode or play with VirtualDub.

Given though that eac3to is "step 1" for any manipulation effort, it would be useful I think if it were to ID these as a mix of interlaced & progressive, if possible (that's where I'd hoped your field/frame count might be way to tell).

[setarip_old]

Anyone know why most recent versions (up to and including v.0.34b) of "Clown_BD" reject input of .MKV files, despite showing .MKV to be an acceptable input format?

[madshi]

What about the repeated beginning?
Should also be fixed. Just give it a try...

I have uploaded a 20MB sample clip
Thanks. Will have a deeper look at this when I finally find some time to fix/improve interlaced VC-1 handling.

[tebasuna51]

With 3.13 I can reproduce the problem at the beginning, but 3.14 work fine for me.

because I don't have any .MKVs to test. Please post the logs (in the Slysoft forum).

I assume that eac3to CLI can handle your files ?

[setarip_old]

@mrr19121970

Hi!

Thanks for getting back to me.I assume that eac3to CLI can handle your files ?Thusfar, I've only used eac3to via your (very impressive) GUI.

Like you, based on the information in post #1 of this thread, I also presume that it can handle MKV as input.

Any further insight that you can provide will be greatly appreciated.

[madshi]

@mrr19121970, your signature says "eacto" instead of "eac3to"... ;)

[mrr19121970]

:o

Changed it now. 52k views on the Slysoft forum, and nobody noticed it.

:o

@setarip_old

like I said, I've no way to test it.

you need to try the CLI version:

"c:\yourpathto\eac3to.exe" "C:\your.mkv" -demux

[setarip_old]

@mrr19121970

Then, perhaps you should include a note in the download that states that this is presently a non-functioning option of your GUI...

The GUI is exactly that, it's only an interface, a presentation layer.

If the underlying programs cannot handle a particular (for whatever reason) then you need to show logs so that the author can address the issue.

[leeperry]

guys, I got a pretty annoying problem....hopefully someone will have an idea :o

I've got the german Revolver BD, w/ the english track in DTS HD MA....I've tried to extract the core w/ eac3to and I get quite a lot of static in different places(not loud ones, so it's not saturation :confused: )
w/ the extracted DTS core, the static is worse in Sonic 4.2 than in AC3filter, I've tried to play the DTSHD file w/ Sonic 4.2 : it's full of glitches but it seems that the static is still there..

a friend of mine tried to play the track in Arcsoft and the static was still there, I guess that's the only way to play DTS HD in its full glory on PC ?

I've read that Sonic 4.3 should also play it, but I've never managed to make it open DTS...does it really play DTS HD ?

either there's some DRC or whatever that's saturating the audio, or the guys at the mastering studio didn't notice that the english track was full of static before encoding it :(

[setarip_old]

@leeperry

Hi!or the guys at the mastering studio didn't notice that the english track was full of static before encoding itAre you saying that the same audio problem is observed when you play your original BluRay disc?

[leeperry]

Are you saying that the same audio problem is observed when you play your original BluRay disc?
well yeah, the DTS core on the original disc has the glitches..from what I know if you play DTSHD in PDVD it will only play the core?

only Arcsoft can decode DTSHD fully, as I understand it? I guess I'm SOL, too bad this happens on my favorite movie :o

I wish I could somehow decode it to FLAC w/o the glitches :D

@madshi:
Today I have demux IceAge2 with eac3to v3.14 (-demux).
After Muxing with TsMuxeR to M2TS, the Blu-Ray subtitles Stream are not Sync.
There is a delay of 2 Min 42 Sec. The subtitles are displayed to early...

I did again with eac3to v3.05. There is everything ok.

[jamos]

That is not a proof at all. tsMuxeR might work just fine with DTS and still screw up LPCM muxing. Perfectly possible.


It could also be your receiver which doesn't handle 7.1 LPCM correctly. Or it could be whatever source device you're using. I don't really know where the bug is introduced in your situation. But from what I can see the bug is not caused by eac3to. So there's nothing I can do for you.



Ok thanks, it probably is tsmuxer. But can you tell me the order that you remap the channels by default when you demux DTS-HD 7.1 to pcm using sonic (ie LF = 0, RF=2, etc)? I can manually remap them using switches like -0,1,2,3,4,5,6,7. if I know the order that you remap them then I could just override it to swap the two channels (FR with Center) so it works with tsmuxer.

It is not the reciever Onkyo 806 handles 7.1 lpcm input fine from my Ps3 and sony bd player. I do not beleive it the source either as this problem occurs with 3 different DTS-HD 7.1 sources. Could be tversity but i doubt that.

thanks for any help...

edit: n/m the new version of tsmuxer 1.8.24 can now import 7.1 wav files and it still mixes the Center with the Right Front. Bug is with tsmuxer thanks for your patience. for those using the pcm demux then using pcm2tsmu workaround you can now use .wav output using eac3to and directly import .wav into the new version of tsmuxer works fine with 5.1 sources.

[jamos]

Ok got DTS-HD 7.1 to LPCM 7.1 to work with Tsmuxer 1.8.24 you need to swap the center and right front channels when outputing to .wav

ex.
eac3to app.dts app.wav -0,2,1,3,4,5,6,7

then import video and wav files in tsmuxer and mux to m2ts.

all channels play fine with lpcm playback in m2ts file streaming to ps3.

This is a bug with tsmuxer.:D

Edit: note that using .wav is very buggy still in tsmuxer..it crashes most of the time. am now trying to use .pcm with remapping.

Ok found a workaround: use pcm output but swap channel 1 and 2 then use the pcm file as input to pcm2tsmu to prepare it for tsmuxer. then use tsmuxer and the channels are now correct. until they fix the issue in tsmuxer this will work if you want correctly mapped channels using streaming 7.1 lpcm to ps3.

ex:
eac3to app.dts app.pcm -0,2,1,3,4,5,6,7
pcm2tsmu app.pcm output.pcm -c 8
then use tsmuxer with your video and use output.pcm as your audio..vola 7.1 lpcm streaming..

got a problem with a movie, 24fps AVC, 7.1 DTS-HD MA. there are no problems listed in the log at remuxing, but apparently there seems to be a problem with the flac track, when its muxed together with the video its all running at ~2fps and the sound is only garbage. the remuxed video file alone plays fine, so I guess its either a problem of the track (or what eac3to does with it) or perhaps also with mkvmerge. but I went back to mkvmerge 2.2.0 and its still the same. the playing back the flac track alone, muxed to .mka then it has the same gargabe sound as together with the video.

Does the standalone FLAC track play correctly on its own (not muxed into MKV)? If so, eac3to is most probably not at fault.

[HanSolo00]

Thanks for adding support for 24.975fps. However, when I test on a blank 100 sec audio clip, EAC3TO seems to use 25fps in place of 24.975fps... since the following produces the same result:

100 second WAV test clip
-24.975 -ChangeTo24.000 produces 104.149s of audio (should be 104.063s or factor of 25/1.001/24)
-25.000 -ChangeTo24.000 produces 104.149s of audio (correctly a factor of 25/24)

The exact FPS for -24.975 option is 25/1.001 = 24.975025

Thanks again I love this tool!

[Snowknight26]

Any reason why one of my 1080i60 streams makes eac3to output 'xxxxxx fields' while the other one 'xxxxxx frames'?

Also, would be nice if when demuxing audio, if eac3to can't correct a, say, -9ms delay, it would add -9ms to the file name.

[anode]

Can you please retry with v2.13? I've done a quick and dirty fix by simply copying the PTS value to the DTS field. I hope that this solves the problem. If not, I'll have to do a proper (and time consuming) fix.

Thank you very much for looking into this, sorry for the late answer...

I've checked the problematic subtitle stream again with 2.13, but the subtitle doesn't display, as with DTS fields set to zero. Only with the DTS entries from tsMuxeR it is displayed. It is a graphical subtitle (colored info tables) which contains 3 OD fields (object definition) in a row (normally only one OD field is enough for some simple text). The easy subtitles (text) are displayed, even with DTS zero, so this is not such a big problem, I think.
PowerDVD displays all subs without problems, DTS zero or with PTS copy (2.13).
If madshi or anybody has some more infos about the relationsship of PTS to DTS in Blu-ray subtitle specs, I would be happy if you let me know. From my own findings the DTS has to be a little earlier (smaller value) than the PTS. Some definition fields like PD (palette info) and END always have DTS info set to zero.

FYI, for a minimal install of Burning ROM and audio decoder functionality, I gave Nero Micro another go. After thorough removal of all Ahead data (files and registry), Micro 7.11.10.0 was installed with default audio & video options, then the single file restored from previous install: C:\Program Files\Common Files\Ahead\DSFilter\NeEacDec.dll, and the BD/HD DVD license entered in addition to that for the main package (in this case Ultra).

eac3to (v3.14) is installed
Nero Audio Decoder (Nero 7) works fine.

So, no need for ShowTime and all that Home and Indexing bloat (or futzing disabling and removing) afterall. :cool:

Ive just tried to demux Body Of Lies bluray and get these errors.(log attatched)
The bluaray is not a seemless branching movie and is a single m2ts. Also running latest anydvd.

edit I think maybe the disc has mastering errors do to the fact that at the times posted by eac3to as errors, there is glitches in video and audio from the original disk. This is a new movie and is not scratched in any way. I will just return for another

Thanks!

madshi, how hard would it be to implement reading from the other formats that libavcodec handles? Would be nice to be able to decode Vorbis, or MP3, AAC, and more with eac3to. Wishful thinking on my part?

The channel order should be FL FR FC LFE BL BR SL SR.

Just because it is 24 FPS rather than 23.976. 24 is included in the BD standard but is relatively rare.

[leeperry]

depending on the sountrack being 1.5mbit DTS core or FLAC(from DTSHD in eac3to), the sound levels are much different ?!
I can hardly hear dialogs in DTSHD FLAC and need to increase the center channel to like 140%

I've got all DRC disabled in AC3Filter and it's the same story w/ ffdshow/sonic 4.2 for DTS core, so what gives ?!

it happens in all the DTSHD>FLAC tracks I've built, and forcing dialog normalization in ea3to doesn't do anything(same CRC whether it's enabled or not)

OTOH transcoding LPCM in FLAC gives proper sound levels, identical to DTS core :o

if anyone's got a clue, I'd love to hear it. thanks!

[evdberg]

I am not sure since what version the following problem is (I had V3.12 and just tried V3.14), but eac3to can not read m2ts files anymore. So when I point to the root of the ripped BD, I get the report as usual. But when I add the title index, eac3to reports there is an error reading xxxxx.m2ts. I am using CrossOver on Mac OS-X 10.5. For the record, this has always worked perfectly fine with older versions. CrossOver has not been updated in the meantime.

the order of PCM 7.1 should be L R C LS Rls Rrs RS lfe

is that the order that you put pcm in for 7.1 with eac3to?

5.0 channel DTS can't seem to be converted to AC3.
The AC3 encoder received a non-supported data format (pcm, 5, 16, -).

Madshi, not sure if this is a bug report or a feature request but anyway...

If I feed eac3to a duff audio file it reports "The format of the source file could not be detected." but the return code is 0. Could it be changed to non-zero please? It seems to be rc 1 for other source file errors.

Thanks.

5.0 channel DTS can't seem to be converted to AC3.

You can use the external encoder Aften:

eac3to source.dts stdout.wav | aften -b 640 -readtoeof 1 - output.ac3

I have Nero 7 installed and just picked up a copy of Arcsoft TMT a friend had and didn't want, primarily to play HD-DVD's since my included PDVD7 with my LG BD/HD-DVD drive only plays BD.

Anyway eac3to can't see either giving the following error messages

Nero Audio Decoder (Nero 7) is not working correctly
http://www.nero.com/eng/store-blu-ray.html
CAUTION: You need Nero 7. Nero 8 won't work with eac3to.
ArcSoft DTS Decoder doesn't seem to be installed

According to what I have read the DTS decoder is via the filter ASAudioHD.ax which according to this DS filter chain, is installed

Also I know Nero 7 is installed since I use it regularly.

This is on Vista Home Premium 32

Anything else I should be looking out for?

Thanks

[edit]

OK some progress. Looks like a path or environment variable issue. Copied all the DLL's from Arcsoft's directory to the eac3to directory and now the Arcsoft DTS decoder works fine. Still no joy with Nero though

Out of interest what DS filter is eac3to looking for when it checks for Nero?

Thanks

[EDIT again!]

Have gone through this thread again and it seems you need not only Nero 7 but the nero HD-DVD plugin. That's no longer been sold so I guess I am stuck with using libav which seems to be fine

I have 6 mono wavs (synced), and now I don't know how can I make a 5.1 FLAC file from it.

Can somebody help me with this?

Thank you!

I have 6 mono wavs (synced), and now I don't know how can I make a 5.1 FLAC file from it.

You can use WaveWizard or Sox (command line) to merge the 6 channels in one multichannel wav file, and Flac or ea3to to convert to flac.

Also you can use an .avs (AviSynth script) and BeHappy to convert directly to flac without the intermediate multichannel wav file.

Then, perhaps you should include a note in the download that states that this is presently a non-functioning option of your GUI...

It's working now.
