eac3to - audio conversion tool

[kurt]

I wonder how you extracted this evo?
this is just one part of the hd-dvd. Don't know which programm was used for extracting anymore... :)
I have this HD DVD. If you're still having problems I could rip it and give it a go. Just let me know.
let's wait what madshi said. If opening it in evodemux everything seems to be fine...

I know I could just demux the vc1 (main movie uses vc1) with evodemux and process it with vc1conv. But I would like to use eac3to rather...

[madshi]

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)
This one is clearly corrupt. Just play the EVO file and you'll see that the image breaks up at one point. You should rerip the disc.

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 guess that either the Sonic decoder isn't working properly for you (in that case use "-libav" or buy ArcSoft). Or maybe your rip is corrupt, which often makes the Sonic decoder crash or freeze. Try reripping the disc.

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.
Try converting to FLAC instead of PCM and check whether the resulting FLAC file plays back in correct speed and without cracks (for playback I'd suggest the madFlac FLAC DirectShow filter). If the FLAC file plays back fine then most probably the problem is caused by either Pcm2Tsmu or tsMuxeR and not by eac3to. If the FLAC is bad, too, I'd be very interested in a sample of that m2ts file!

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.

http://www.stfcc.org/misc/shootemup.cut.dts
Thanks for the sample. Seems to be a bug in libav. You'll have to use ArcSoft, Sonic or Nero for decoding. Tested with ArcSoft and the result is fine.

let's wait what madshi said. If opening it in evodemux everything seems to be fine...
EvoDemux doesn't care about corruption. eac3to does.

I know I could just demux the vc1 (main movie uses vc1) with evodemux and process it with vc1conv. But I would like to use eac3to rather...
You could still demux with EvoDemux and then use eac3to for everything else. eac3to can do exactly the same thing as vc1conv on raw demuxed VC-1 streams, too ("eac3to source.vc1 dest.vc1" will remove the pulldown etc). BUT your best bet is to rerip the disc. After that eac3to should properly handle the EVO file.

[kurt]

ok, thank you for your suggestion. I'll look into the main movie and see if it is corrupt too :)

(I'm sitting here behind a remote desktop so I didn't notice that the sample is garbled)

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

Try using just eac3to, also use eac3to and more gui. Use the Remap to Blu ray 6 channel options as well, and output to .wav. tsMuxeR accepts it as PCM, unfortunately I have no way of testing due to reciever limitations. Please try this, I am curious to see if it works.

[Duppie]

@Madshi

Thanks for the information. Unfortunately I can only test PCM since the PS3 does not accept FLAC and my PC is too slow for HD playback. I also think FLAC is not supported in .m2ts containers. Is there another way I can test eac3to for you to determine if the problem is with Pcm2Tsmu or TsMuxeR? The thing I cannot understand is that it works fine with 2.57 with the same Pcm2Tsmu and TsMuxeR versions.

@Odin24

Thanks for your suggestions. I really would like to keep it as simple as possible (eac3to.exe file.m2ts audio.pcm). For now I will stick with eac3to version 2.57 until I do some more tests on 2.63.

Ok, if it works fine with 2.57 then this looks like an eac3to bug. Can you upload a little sample of that m2ts file for me? 50MB would be great. Thanks!

BTW, I didn't suggest that you use FLAC for your movies. I only suggested that you should convert to FLAC as a *test*. Your PC may be to slow to playback HD video, but it will definitely not be too slow to play a FLAC audio track. So that's a valid test to check whether the FLAC audio track sounds ok, or whether it plays too fast, too, and with artifacts.

Decoding from TrueHD never need remap options.

Always is recommended decode to wav but, when the wav file is >4GB, tsMuxer don't work. The workaround is decode to lpcm and use Pcm2Tsmu v1.3 (http://www.sendspace.com/file/som3na) to insert the special headers required by tsMuxer.

If the parameters are correct, example:

Pcm2Tsmu input.pcm output_tsm.pcm -c 8 -i 16 -s 96000

(for a 8 channels, 16 bitdepth, samplerate 96 KHz) and tsMuxer accept the audio, can't be a Pcm2Tsmu problem.

@Duppie, if the flac file play properly like madshi say, please use the Pcm2Tsmu thread (http://forum.doom9.org/showthread.php?t=138417) to post a sample and continue the discussion.

[Duppie]

@Madshi

Sorry, you are right. The audio can be tested alone with no powerfull PC. I will do some more tests over the weekend. If need to be, it is my first upload, where can I dump a sample if it is really a problem of eac3to?

@tebasuna51

Thanks for that. Will do, after some tests.

[nautilus7]

where can I dump a sample?
sendspace, mediafire, repidshare etc. To cut a sample use a hex editor like HxD.

The problem is that eac3to does not remap the channels to Blu-Ray order when exporting to PCM. I guess it should do that?

P.S: Oh, 6.1 channels! My fault. There's just something missing. Will add that to the next eac3to build...
P.P.S: Blu-Ray does not support 6.1 LPCM. Instead it only supports 7.1 LPCM, as far as I know. So should I enforce channel doubling when exporting to PCM?

When you say >4GB... tsMuxeR doesn't work. Do you mean it won't accept the .wav file at all, or there will be playback problems after muxing?

[EPiPH0NE]

^^^It Won't accept the file.

tsMuxer, like other soft, accept the wav but don't play/use the full length.

Converting TrueHD, DTS-MA and DD+ to PCM. Is one library better and more exact then the next? I don't have nero or total media installed and just planned on using the default library.

I want the most accurate conversion available what should I use?

Author has selected the most accurate decoders even you don't have them; so you don't have option B but just an option A which is available on default library :)
I mean there is no option B in default library.

[Jeff Flowerday]

Having a little trouble understanding you. Are you saying the default library does as good a job as nero or any of the other decoders?

[rica]

Having a little trouble understanding you. Are you saying the default library does as good a job as nero or any of the other decoders?

No.
The best decoders are unfortunatlely the commercial ones like nero or TMT which are selected by Madshi as default.
If eac3to can not find those defaults, that time it will use the default ones coming with the library.
For any particular format, you don't have two options since library gives only one default decoder for any particular format.

[Jeff Flowerday]

No.
The best decoders are unfortunatlely commercial ones like nero or TMT which are selected by Madshi as default.
If eac3to can not find those defaults, that time it will use the default ones coming with the library.

So for the most accurate conversion from TrueHD/DTS-MA/DD+ to PCM uncompressed I should purchase say TMT?

[nautilus7]

Is it sooo hard to read the 1st post?

[Jeff Flowerday]

Ok I see mention that the default libav works perfectly for TrueHD. What about DD+ though?

[rica]

So for the most accurate conversion from TrueHD/DTS-MA/DD+ to PCM uncompressed I should purchase say TMT?

The answer has been given on the first post by madshi:

default decoders used by eac3to:

MP1, MP2, MP3: libav/ffmpg (free-from library)

(E-)AC3: Nero (commercial)

AAC: Nero (commercial)

TrueHD: libav/ffmpeg (free-from library)

DTS(-HD): ArcSoft (commercial)


So finally Nero 7 + HD-Plugin (not 8 at all) is recommended for DD+ and TMT is recommended for DTS/DTS-HD.... For TrueHD, libav/ffmpeg is recommended which is coming with the library.

And, you don't have to purchase anything; it is up to you. (trust your own ears first; it is a rule.)

To use flac with 3/1.0 channels maybe we need split the surround channel in:
BL = 0.707 x S
BR = 0.707 x S
and use a 3/2.0 configuration supported by flac.

Yeah, sounds like a good workaround.

was this ever implemented? i have a bd with a 4ch pcm track (3/1.0 configuration) and eac3to seems to treat it as 2/2.0 when encoding it to flac

sample: http://www.sendspace.com/file/gvx7sn

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!!

here's a sample from another disc but with the same problem

sample: http://www.sendspace.com/file/gvx7sn
In order to make this fully work there are 3 things that need to be done:

(1) eac3to must properly detect the channel configuration. The track could be 2/2 or 3/1. The next eac3to version will detect that correctly for m2ts sources.

(2) FLAC used to not support funny channel masks. But I've seen that there's a way now to store a WAV channel mask as FLAC meta information. So storing 3/1 in FLAC should be possible now. But eac3to will have to read/write that channel mask meta information. I've put that on my to do list, but it might take a while until I find the time to implement that.

(3) The FLAC decoder (e.g. madFlac) must be able to read and interpret the channel mask meta information. madFlac doesn't do that yet.

here's a sample from another disc but with the same problem

http://www.sendspace.com/file/kifr28
Thanks. Same problem as with the other sample. Will be fixed by the next eac3to version.

[monohouse]

does eac3to allow joining independent mono wav/raw files into a single multi-channel file ? because it seems there are no wave editors that are capable of reading a single 7.1 channel wav larger than 4 GB, while some maybe able to allow the one (larger than 4 GB) but that same program does not allow the other (7.1 channel) and the other way around, there may be one or two programs that do support reading such a file fully (both 4 GB size AND 7.1 channels), but they have other drawbacks (only open first 30 minutes (nero) and others open the multi-channel file and open all the channels as mono separated channels, without support for joining them into a single .wav file (cooledit))

You must be making something wrong.

Extract vc1 directly from your evo; this is the best way.

Madshi, is there any chance that eac3to will one day include remuxing to EVO/(M2)TS? I only ask since you're clearly a genius, eac3to now does such a great job making elementary streams but there seems no way to mux some of them back together due to the limitations of all the free muxers (talking about TrueHD). I'm sure remuxing is a lot more complex than demuxing but is it in your thoughts?

I'm not madshi, but people keep asking this and the answer is always the same. Implementing an evo/ts muxer is way to much work, madshi doesn't wish to do that.

But while we on the subject is TSMuxer really the only thing we have? Is there absolutely nothing else either free or reasonably priced?

Are you saying the issue is most likely pcm2tsmu or tsmuxer?

Whenever I try to mux a video track to an mkv (mostly when the Blu-ray contains multiple .m2ts files), the muxing process stalls very early on yet eac3to still sits there as if its going. The resulting .mkv is always 2,752,512 bytes.

Doesn't matter if its H.264, VC-1, or MPEG-2 (haven't tried the latter).

Anyone have any issue converting the TrueHD track on the 300 HD-DVD to pcm? After running it through pcm2tsmu and then muxing it into a m2ts container. I'm only getting white noise on the pcm track. The ac3 track that I created at the same time is fine.

I tested the result in both TMC and my NMT box.

I am also having this same problem, although I have ruled out both pcm2tsmu and TsMuxer as the cause.

I have an EAC3 audio track which was ripped from an HDDVD. I have tried converting it to PCM with the default Nero, and also forcing libav. In both cases, the output file is just static noise (tested with GraphStudio).

I don't believe the source EAC3 is corrupted because I can play it back fine using GraphStudio. Although, I had to do this a weird way using ArcSoft - I was not able to connect the EAC3 source directly to either "Nero Audio Decoder 2" or "ffdshow Audio Decoder" filters. Admittedly, I do not have much experience using GraphStudio, maybe someone could inform me of the correct path to play through nero or libav?

Anyway, as you can see, the static problem occurs during the eac3to step. If a sample is needed, I would be happy to upload one somewhere. Just let me know what is needed and how to cut the files, I haven't done that before.

Here's 15 seconds from the beginning of 300, it should suffice to help find the problem if it is eac3to. I know "The Invasion" is doing something similar to me as well.

I've only seen it happen on 2 TrueHD sources, 2 other ones were fine, the 4 DD+ I've done so far have all converted fine using nero.

If you want to clip a sample just use tsremux on the evo and tell it cut off all but 15 seconds from the end, it will package the beginning 15 seconds up in a container for you.

Please don't take this as a criticism of your remarkable application, rather as a sign of absolute faith in your ability :)
I totally agree with you. Sometimes i wish all audio/video editing/playback programs were written by madshi.
Thanks, guys... :)

I'm not sure what is going on. It seems to work for everyone else. I'd suggest that you uninstall and reinstall the Haali Matroska Muxer. Maybe that fixes the problem?

I am also having this same problem, although I have ruled out both pcm2tsmu and TsMuxer as the cause.
How did you rule that out?

I have an EAC3 audio track which was ripped from an HDDVD. I have tried converting it to PCM with the default Nero, and also forcing libav. In both cases, the output file is just static noise (tested with GraphStudio).
Does GraphStudio support raw PCM files in the first place? If you want to check whether eac3to is doing everything correctly or not you should ask eac3to to convert the PCM file to WAV (if it's smaller than 2GB) or FLAC (if it's bigger than 2GB) and then try to play that.

Anyway, as you can see, the static problem occurs during the eac3to step.
"As you can see"? Sorry, I don't see that yet. Where is the proof?

Here's 15 seconds from the beginning of 300, it should suffice to help find the problem if it is eac3to.
Thanks for the sample. I've done this:

eac3to feature.m2ts 2: test.pcm
eac3to test.pcm test.wav

And the resulting WAV file plays perfectly fine. So as far as I can say, eac3to is doing everything right.

eac3to is doing everything right, problem solved (http://forum.doom9.org/showthread.php?p=1186545#post1186545).

Thanks madshi.

eac3to v2.64 released

http://madshi.net/eac3to.zip

* added channel mask reading support to Blu-Ray PCM track parser
* added channel mask reading support to TrueHD parser
* added channel mask reading & writing support to FLAC decoder / encoder
* changed 5.x channel mask from $03x to $60x
* changed 6.x channel mask from $13x to $70x
* mono wavs output now creates correct names for funny channel masks
* when transcoding 6.1 sources to PCM, 7th channel doubling is activated now
* fixed: DTS channelmask detection was incorrect for some strange configs
* fixed: sometimes the h264 video stream of a Blu-Ray m2ts was not detected
