It just seemed kind of strange that watching the bitrate (HDDVD THD remuxed to BD --> on the PS3) that it only peaked at around 1.7mb/s, even during high action scenes. Where on most BDs with THD they peak around 4.5mb/s.
If the TrueHD track is only 16bit then it's *MUCH* smaller (and has much lower peaks) compared to a track with full 24bit.

If (E-)AC3 tracks are decoded to 64-bit floating point, why is that when converting to WAV they're then reduced to 24-bit? Wouldn't it be best to reduce the depth to, say, 32-bit floating point?
First of all it depends on the decoder. I patched libav so that it gives me the full floating point decode. But Nero and Sonic decoders internally downconvert to 24bit PCM. Now with libav eac3to by default downconverts to 24bit PCM if you ask it to create a WAV file. The reason for that is that 24bit PCM is usually plenty good enough. The main purpose of keeping things in floating point is if you want to do further processing on the data or if you want to feed the data to an encoder which wants floating point data. If that is the case, simply use the "-full" switch. Then eac3to will create floating point WAV files (if floating point data is available).

This one demuxes fine for me with v2.74. Can you please retest with v2.74?

madshi, I have a problem with slowing down that skyHD movie I sent you the 10mb sample to fix the skyHD ac3 tracks. its 50i and when I use -slowdown then the video turns out to be about 2-3 mins longer than it should be (audio seems to be fine though). It has video gaps, but the problem stays the same after redoing the same command line. 50 mb sample:

Thanks. Looks like a bug in eac3to. Will try to fix that in the next build. Might take a few days, though...

I don't think that tsmuxer can reliably detect the number of channels in a DTS-HD file. AFAIK eac3to is the only freeware tool that can do that.

The DTS sample you uploaded is kind of strange. I don't have any problems with the channel order. However, the front left and front right channels seem to be plain broken if I decode the track to 7.1 with ArcSoft. I'm not sure if the track itself is broken or whether this is caused by a bug in ArcSoft. You can use the "-6" parameter to force ArcSoft into decoding the track as 5.1, only. I think this is the best you can do right now.

So you mean to say that the DTS sample IS 7.1, eac3to finds this properly and then, using 6 channels, I would of course loose the data for the other two channels :( Not your fault of course, just curious... And apart from ArcSoft there seems to be nothing that can decode 7.1 channels right? Libav/ffmpeg can just do 5.1 like Nero 7 as well :(

Correct.

Well, if you absolutely must have all 8 channels then you can do "eac3to source.dts 6.wavs -6" and also "eac3to source.dts 8.wavs". That way you will get 6 WAV files for the 6 channel decoding and 8 WAV files for the 8 channel decoding. You can then use the 8 WAV files - but replace the front left and front right channels with those of the 6 channel decode. The only problem then is to convert the 8 channels back into one WAV file. eac3to cannot do that currently. But I think wavewizard can.

If that warning appeared exactly once then there's a chance that 0.8333ms of your track are not lossless. The other 5-10 million milliseconds of your track are still lossless.

is there any way else to join the big Hancock Playlist?
TSmuxer destroys some informations while joining and remuxing. I Want to play it in a PCH B-110. When I remux it with TXRemux again it is okay but buggy. The problem is the joing of the Playlistfiles. 1:1 copied full Mainmovie m2ts work fine after remuxing with TSRemux, so the joining and TSmuxer is the problem.

Can eac3to do that?! Joining multiple m2ts files (like it does with evos)?

Thanks, greetings Michael

Hey Madshi, not sure if this was suggested I tried searching...

Any thought around an option to downmix/convert DTS-HD HR/MA 7.1 or TrueHD 7.1 down to DTS-ES 6.1 or Dolby EX 6.1? I guess this would also require that we use encoders that are capable i.e. DTS Pro Encoder or I think Ulead's Videostudio can do Dolby EX or Vegas but I'm not 100% sure...

Also why is the size of the file for 2.0 and 5.1 the same?

My last question, the bitdepth of ac3 files is always 16bit
and will only be displayed by eac3to if they are more than 16bit?

But eac3to indicates this file as only 2.0 and not 2.1.
Is this correct or am I missing something?
Is correct, the mix of LFE channel is inside the front channels
BTW, Dolby don't recommend mix the LFE channel inside a DPL mix.

Also why is the size of the file for 2.0 and 5.1 the same?
The size is determined by the bitrate, if you don't say nothing the default 640 Kb/s is applied.
For 2 channels is recommended 192 Kb/s or 224 Kb/s

My last question, the bitdepth of ac3 files is always 16bit and will only be displayed by eac3to if they are more than 16bit?
The precision measure in compressed audio is the bitrate and the bitdepth don't have sense.

If you define the bitdepth like the number of bits of an audio sample at the samplerate frecuency then an ac3 6 chan. 48 KHz. and 640 Kb/s have an average bitdepth of:
640000 / (6 x 48000) = 2.222

In DTS headers there are a field to remember the bitdepth of the source uncompressed audio (but isn't reliable), in ac3 header don't exist.

Both, AC3 and DTS, store samples in fequency domain with a precission equivalent to 20-24 uncompressed bitdepth, then when you decompress you must select at least 24 bit ignoring the source bitdepth.

You need it only if eac3to (haali matsoska muxer) is unable to handle the source. eac3to will prompt you to use it in that case.

6th November 2008, 21:24

madshi, quick question - indirectly related to eac3to :)

I had already told you that some of my audio streams are corrupt, and that eac3to breaks with an error.

Now, that is fine, and I can live with it :) I can demux these streams to the end with TSMuxerGUI, and then merge them into the MKV.

However! The "dialnorm" is still in the resulting stream, and I'd really love to get rid of it, e.g. in E-AC3 streams :) As I can see from the output, you don't recode this stream when I demux to ".eac3". Dialnorm is however removed. So my guess is that this is just some byte which is set somewhere in the stream... Could you give me a hint on where to look for it? Maybe I can just use a hex editor and remove it :D Thank you :)

Which movie is that? Can I have a sample?

i'll have another problem with slowdown audio
You're using the "-quality=ultra" option which means that you're using the r8brain resampler. I'm not sure but I'm suspecting that r8brain eats too much memory and maybe that's why processing stalls. Try without the "-quality=ultra" option. Does it work then?

"ultra" is probably a bad name. I should rename the option to "-r8brain" because I'm not actually sure that r8brain has better quality than SSRC. It's quite possible that the opposite is true.

will nero9 work for directshow? Or has it the same limitation as nero8?
It works in graphedit, when you manually register the DirectShow filters, but eac3to currently doesn't support it.

madshi any chance you update eac3to so it supports latest aften (http://code.google.com/p/wavtoac3encoder) release? The revision used currently should be about 100 revisions old. :(

Do you know the exact downmixing matrixes needed for downconverting 7.1 to DTS-ES compatible 6.1/5.1 or Dolby EX compatible 5.1?

I wish I did so I can help you out. From a High level (let's exclude Dobly EX for now) DTS-ES can be encoded in either 1536 or 768kbs which gives the same flexibility as normal DTS does.

The rear channel or what is call Center Surround (Cs) requires a Phase shift when it is a discrete channel but does not when it's a matrixed created Phantom channel. The only encoder that I am familiar with that can do DTS-ES is the PRO Encoder directly from DTS or the Master Audio Encoder again direct from DTS.

I suspect that a simple Stereo to Mono downmix of the Left and Right Rear Surround channels is sufficient and then using that as the input to the Center Surround with the Phase Shift option enabled in the DTS Encoder will do the trick for 7.1 and just a direct input for the single rear for 6.1.

Dolby EX is a whole other story and I'm not sure logically how it's matrixed or how best to downmix to DDEX. DTS seems fairly straight forward. The PRO encoder / DTS Suite is only $250 but the Master Audio Suite is $1,500! :eek:

I don't think VOB files ever contain chapter info. Certainly in a DVD structure, that information is in the .IFO file corresponding to the TitleSet. IFOEdit will extract chapter info from an IFO file for you.

command line: eac3to h: bruce.logwell, the problem is pretty obvious. Your command line is wrong and surely this is not the complete command line you use.

Mmhh...this was only to show the content of my bluray. I converted more than 30 bluRays and HDDVDS with eac3to - without problems.

The command I use to convert:

1)
eac3to h: 1) 3:bruce.mkv 6: bruce.ac3

2)
eac3to h: 1) 3:bruce.mkv 6: bruce.ac3 -libav

3)
eac3to h: 1) 3:bruce.mkv 6: bruce.wav

and so on.

This one demuxes fine for me with v2.74. Can you please retest with v2.74?

The sample I made doesn't work for me in 2.74, says "The format of the source file could not be detected." but it's definitely the end of the file.

Do you have nero? Does it work? What is the exact error message you get? Do you have anydvd running in the background in case the disc is protected?

Ok, this pretty much explains what's wrong, huh? Libav doesn't support the track because it uses some special features of the e-ac3 standard. Nero will work though.

Anyway, for the good of our community i suggest you run the following command

eac3to h: 1) 3:bruce.mkv 6: bruce.eac3 -10mb

to create a 10MB sample of the track and upload it here, so it can be forwarded to the libav developer. :)

btw, which movie is it?

Thanks for your help.

The Blu-Ray Movie is "Enter the Dragon" in German: "Der Mann mit der Todeskralle".

I will create a sample - but how can I upload it!

btw:
I have a second problem with the Blu-Ray of "Kingdom of Heaven".

The Command is:
eac3to I: 1) 4: kh.dts

4: DTS Master Audio , German 5.1 channels 24 bits, 48 khz, (core DTS, 5.1 channels, 24 bits, 1536 kbps, 48 khz)

After a few minutes the message appears:
[a04] This track is not clean. Processing aborted.
[a04] Please clean the track with delaycut and then retry eac3to.

What does this mean?

:thanks:

[a04] This track is not clean. Processing aborted.
[a04] Please clean the track with delaycut and then retry eac3to.

What does this mean?This means that the track has some kind of corruption in it. Only possible way to fix this is to re rip the disc.
Do you need the master audio track or only the core? If the second, you can try the -core switch to see if it works.

Can you add MKV to "Supported source formats" ? PLEASE ! :helpful:

P.S. I know there are other "tools" for demux all video and audio tracks of an mkv but I'd like (as many others) to keep things simple (and not having a lot of programs installed)
:thanks:

Maybe some day. But probably not anytime soon.

looking also foward for this :thanks::)

Damn. Obviously the corruption is on the origin blu-ray. -CORE won't work - same result.
What do you mean with re-rip? I have the Blu-Ray already on my hdd as ISO.

The sample you made is too small (only 96KB). Maybe it's not big enough (eac3to can detect its format though).
Do you have a slow connection and it's difficult to upload a bigger sample? If it's not a problem please make a 5 -10 MB sample.

Thanks.

Problem 2 (kingdom of heaven)
I bought the bluray yesterday and after 2 times getting an error from eac3to by accessing to the BDROM direcly i ripped the whole blu ray to my hdd. Unfortunately, the error appears again.
So i gather, there is an error on the bluray inthe hd-dts track :devil:
But.....: playing the Blu-Ray directly from BDDVD or from the ISO with PowerDVD 8 everything wents fine! So, maybe the error is in eac3to???

Thanks!

You have to register Nero filters manually.
You can use Radlight Filter Manager for this purpose.
And if you want eac3to to use Nero filters, you have to put this option at the end of the line: -nero

(BTW, if you don't re-encode but just simply extract the audio (without changing it), decoders will not be used.)

Now two ( probably stupid ) questions : when a m2ts file has more THD tracks what I have to digit to select only the second THD track?
You should first ask eac3to to post a track listing (e.g. "eac3to movieFolder 1)") and then simply fetch the track index from that list. E.g. if the list shows "2: TrueHD, ..." and "3: TrueHD, ...", you can use "eac3to movieFolder 1) 3: whatever" to select the 2nd TrueHD track.

Again; I have used various releases of eac3to but when I have a m2ts file like input it's never specified the language of the various audio tracks.
The language is shown only if the full Blu-Ray folder and file structure is still intact. The language information is stored in the CLIPINF folder.

The sample I made doesn't work for me in 2.74, says "The format of the source file could not be detected." but it's definitely the end of the file.
It doesn't work because it doesn't begin correctly. If it's an M2TS file, the 5th byte must be a 0x47. If it's a TS file, the first byte must be a 0x47. So you can use a hexeditor, search for the first 0x47 byte and remove the first few bytes of the file, until the fifth (or first) byte is 0x47. If that doesn't work, just repeat the process another 2-3 times. At some time eac3to will properly detect and handle the file.

Problem 1 (bruce-lee 1.0 ac3)
Sorry, obviously something went wrong. Here the 10mb-file:
http://rapidshare.com/files/161846249/bruce10MB.eac3
Thanks. I'll forward this to the libav E-AC3 decoder maintainer.

Problem 2 (kingdom of heaven)
I bought the bluray yesterday and after 2 times getting an error from eac3to by accessing to the BDROM direcly i ripped the whole blu ray to my hdd. Unfortunately, the error appears again.
Is this with eac3to v2.74? Which country is this Blu-Ray from?

Created m2ts by TSMuxer (includig thd+ac3 demuxed by eac3to) can no be remuxed as BD by TSRemux
I wonder why people continue to ask questions about tsMuxeR/TsRemux problems in this thread? This is the eac3to thread! If tsMuxeR or TsRemux don't work correctly then you should ask in the tsMuxeR/TsRemux threads for help.
