Couple things: time to upgrade to 3.11, -1536 is understood, and add -resampleTo48000.

Given the directory structure, that's a Rule #6 and shouldn't be discussed here.

Why ?
Because the ripped blu-ray disk is in my downloads dir ?

[jj666]

It's just some friendly advice, as the rules clearly state we don't discuss downloaded content. Once that is out of the way, it's a very friendly forum :-)

I don't really know. I installed full Nero 7, registered proper (actually bought by me) license codes for Nero 7 and for the Blu-Ray/HD DVD plugin, and Nero 7 decoding works just fine for me, without having to manually register any filters.

Yeah, I was trying to be clever with a minimal install (Micro + any additional dll/ax restored). For now I have installed ShowTime (along with Burning ROM which I do want) and it "works fine". Of course there are superfluous filters and all that Nero Home & Indexing nonsense too which while offensive on priniciple I would not be obsessive about taking space (once disabled) except that I want to limit the backup image size to one DVD-5. I suppose I can instead just start eliminating unneeded files (move or archive) until something breaks ;)

Thanks again for your help and great proggy.

...Actually txMuxeR needs semicolon-delimited timecodes. You should check-out QPFile Generator discussed here (http://forum.doom9.org/showthread.php?p=1240718#post1240718) which creates --custom-chapters list as well as qpfile.txt, celltimes, etc.

[dorati]

But when paste into the window, the format I use above is right !

Ah, without looking at your (pending) attachment let me guess--you are using the tsMuxeR GUI. Still, qpfile gen also outputs a timecodes file just like you want.

That is very good software. I prefer using it to the TsMuxer GUI as it also reduces the number of steps when converting audio.

Hello,

having been a silent watcher for several weeks now and still on a steep learning curve and having read posts hither and yon I need someone to confirm the following for me before I commit myself to command line hell.

I want to either extract the dts Core of a dts HD track and presumably get 24 bit/48khz (or 96khz on the rare occasions they exist) 5.1 soundtrack or convert DTS HD into DTS 24/96. The reason for this is that I want to continue to use my much loved AV32R processor whch will handle DTS 24/96 via spdif but has no hdmi input to transfer DTSHD. this is because it A sounds fantastic an B has very good room equalisation software that is not available via the 5.1 bypass.

Goals -

1 - have 24bit/48khz 5.1 dts output via spdif. (presume yes if core is encoded as such)
2 - have the above tagged as DTS 24/96 if necessary to kick the AV32 into life.(what i am unsure of)
3 - Core is ok if it will achieve 2 above. So far my tag has not lit up to say 24/96 - just vanilla DTS

6.1 and 7.1 not needed.

I know i can extract the core from a DTSHD BluRay - the confirmation i cannot find is whether it will identify as DTS 24/96 via spdif.

Will playback via MPC HC/ffdshow and auzentech digital out.

AV32R will decode a 24/96 stereo flac file (presumably output as linear pcm) no problem. Is fine with dts es too. spdif cant handle DTSHD but i am given to understand elsewhere that it can cope with 24/96.

Sorry to be a quality junkie and somewhat exacting.

Am loving my decoded HDCD's. Thank You.

Anthony

[TinTime]

The core can be 96/24, but only if the full track is DTS-MA with a sample rate of at least 96Khz. I haven't seen any yet.

So extracting the core with eac3to (assuming it gets the 96/24 stream and not the plain core?) is your best bet for DTS if you want it passed over spdif.

Do you know for sure that you have a blu-ray with DTS 96/24 in it's audio?

[GZZ]

I get the following warning in eac3to, not sure what it means and if I should be concerned about it:

I got a problem with this file on the Popcorn Hour. Autoframerate isn't working, PCH uses 23,976 (or ,999) instead of 24,000 hz as output. I thought it might be a muxing problem.

How can I distinguish between container and bitstream framerate? which tools can change the framerate to 24.000?

I tried demuxing the elementary stream with eac3to and loading it in mkvmerge (while specifying fps to 24), but eac3to reports the same message of the resulting mkv as before....

@Jeff Flowerday and others who have requested the ability to split eac3to output by chapter for concerts and such, I have whipped up a little GUI to do just that!

After selecting the disc to split, it lets you choose which audio stream to use and which chapters you want to output. You can also edit the metadata and chapter names. eac3to is then called to demux the disc, and HDCR then splits it into individual FLAC files. WMA9 Pro 5.1 is also supported for output, for those that have a receiver that can process it (Windows Media Encoder must be installed for this to work.)

Currently HDCR only supports HD DVD, but Blu-Ray support is next on my to-do list.

XP and newer OSs automatically sort the tracks correctly even with only 1 digit. Are you using an older OS than XP?

Is it possible to skip the last Chapter, when the Last Chapter is = Movie-Length?
Yes, that should be possible.

And is it possible to have one option to create the Chapters.txt in a format to direkt use in TsMuxer?
Possible, yes. But I don't want to do it. I don't like the idea of adding a multitude of different switches for a multitude of different programs out there. tsMuxeR has been requested, so has foobar2000. Maybe there are more. I'd have to add one switch for any such application. I don't like that idea...

1 - have 24bit/48khz 5.1 dts output via spdif. (presume yes if core is encoded as such)
2 - have the above tagged as DTS 24/96 if necessary to kick the AV32 into life.(what i am unsure of)
3 - Core is ok if it will achieve 2 above. So far my tag has not lit up to say 24/96 - just vanilla DTS
It doesn't make any sense to flag the DTS 96/24, if it isn't really encoded that way. Actually it would play incorrectly, if we did.

If the original DTS-HD track is 96khz then the core may be 96khz or 48khz. So extracting the core may be what you need - or not. Depending on how the studio encoded the track. eac3to lists both the core and DTS-HD track properties, so you always see whether the core is 96khz or not.

Maybe that solved the specific playback problem you had. But it will not modify the video bitstream from 23.999p to 24.000p. If you want to do that, you can use eac3to's "-changeTo24.000" option.

XP and newer OSs automatically sort the tracks correctly even with only 1 digit. Are you using an older OS than XP?

Only explorer sorts them logically for humans - I can imagine the calls MS support would get if it didn't! Batch commands such as DIR and FOR will sort them in the strictly correct order though (e.g. 10 before 9).

As far as I'm concerned I've got a step in my demux batch script to zero pad any single digit filenames after the eac3to demux so I'm not bothered either way about this.

Which kind of 2nd pass? For removing clipping? For fixing audio gaps/overlaps? Something else? I don't really see why you would want to skip any of that. IMHO it should all be done.

Hello everyone, I have been lurking here for several weeks and trying to digest all the information you guys have given me.

Madshi, thanks so much for a wonderful tool this has helped out so much.

I have been able to backup several of my HD-DVD movies and move them into MKV for playback on my Western Digital My TV, which I love. All of the discs with DD+ I am able to convert over to DTS and they play fine with very few errors. Although I am running into a problem, I do have 5 or so discs with Dolby TrueHD on them and I want to get those moved over to my WD as well. I have tried converting the audio to RAW, FLAC, PCM, and LPCM with no success. Every time I do I just get a Dolby Digital sound not the TrueHD sound that I am looking for. I have a Pioneer VSX-92 that supports all of the formats and would be able to decode the audio if only I could get it sent over. I am not concerned with space, since it's only 5 movies so 50 gigs per movie is not a big deal. I just want to know if it can be done.

Currently I am backing the movies up with AnyDVDHD, then using EVOdemux to join the two EVO files, and remove the TrueHD track. I then open Eac3to and change the audio over to whatever format (PCM,LPCM,FLAC) then I use either TSmuxer to combine the files to make either an M2ts or a TS file, although I get an error in TSmuxer that says it "Can't detect stream type." I also use Ripbot 264 to create an MKV files, which like I said play fine, but it's not TrueHD.

So my question is really, has anyone successfully been able to convert the audio and video into a container like TS or MKV?

I appreciate your responses and I hope you will forgive my Newbiness.

I have tried converting the audio to RAW, FLAC, PCM, and LPCM with no success. Every time I do I just get a Dolby Digital sound not the TrueHD sound that I am looking for. I have a Pioneer VSX-92 that supports all of the formats and would be able to decode the audio if only I could get it sent over. I am not concerned with space, since it's only 5 movies so 50 gigs per movie is not a big deal. I just want to know if it can be done.



from WD i know only the HD TV: http://support.wdc.com/product/download.asp?groupid=1001&lang=en

it's HDMI 1.2, no passthrough of THD & and other new stuff, so the problem is not with eac3to or your pioneer.

unless it shouldn't, clipping removal changes the signal when in reality clipping only matters when you can actually hear it, if you can't then it isn't clipping (not to mention clipping removal is a subjective thing (when performed in a digital fashion), and usually belongs to the sound mastering department (meaning there are plugins [VST etc] which are better equipped and are more suited for this kind of work), but if you are changing the signal you will always hear the changes because the changes are digital (see that's the thing, im still not quite sure how you define eac3to to be, is it an mastering tool ? (because it does perform dither and such) or is it a converter ?, or you still haven't decided on borders for the program ?)
I'm sorry to say, but you don't really seem to know what you're talking about. There are 2 totally different situations:

(1) If you have floating point data where some samples have a peak which is out of spec, converting this audio data to PCM would result in clipping. Solving this problem is extremely easy: It's just lowering the volume of the whole track a little to make sure that no audio samples have too high peaks. This is an absolutely lossless process (if done in floating point). The signal is not changed (just the volume is changed), it is not a subjective thing, and nobody will hear the difference (except for the volume difference and the solved clipping artifacts, obviously). And no VST plugin can do that any better than eac3to. I would call this process "clipping prevention".

(2) If you have a PCM track which was converted without "clipping prevention", then some VST plugins can detect that and can try to undo the damage. This is a complicated and error prone process which is difficult to do and really changes the signal. I'd call this "clipping repair". eac3to doesn't even try to do that.

So again: There is no reason whatsoever to disable eac3to's clipping prevention system. It has no disadvantages (I know of). Except longer processing time, of course...

And dithering: If eac3to is supposed to output PCM tracks from any source then there's no other way than to use dithering. It's a necessary evil if you want to reduce audio bitdepth or if you want to convert floating point audio data to PCM. If I removed dithering, eac3to would lose half of its functionality.

the gap/overlap is sometimes wrong
Then send me a sample and I'll try to fix it.

@six172, you may want to ask on the tsMuxeR thread or on a "Western Digital My TV" thread, if there is any such. Can't help you out since this is not an eac3to related problem.

@sixt, you're doing a very long winded process with out dated software. drop EVOdemux, get tsMuxeR v1.8.18, wait for eac3to 3.12 (that fixes the HD-DVD stream language issue) and try again.

Hi, a newbie seeking advice. Hoping to convert arbitrary HDTV .ac3 (could be any kbs, #channels) to 224k 2-channel .ac3 but I am not sure what the options do. So far, I have guessed
"C:\SOFTWARE\eac3to\eac3to.exe" "T80 3_2ch 448Kbps DELAY 0ms.ac3" "T80 3_2ch 448Kbps DELAY 0ms-eac3to.ac3" -224 -down2 -mixlfe -resampleTo48000 +6db
but am not sure what "-mixlfe" does. Or "-phaseshift". The ac3 always seems very quiet so I bumped it up by an arbitrary 6db.

Can someone please explain and confirm I'm doing the right thing ?

I gather DRC is a good thing since it lessens the difference between loud things such as bangs and normal speaking, so when increasing the volume so I can hear them speaking (I'm slightly deaf) it won't blow the family away when a bang occurs... is that right ? and if so, can we do DRC with eac3to ? (I only have the eac3to and no Nero etc).

[tebasuna51]

but am not sure what "-mixlfe" does. Or "-phaseshift". The ac3 always seems very quiet so I bumped it up by an arbitrary 6db.
-mixlfe is not recommended by Dolby because can produce artifacs, but you can make the two versions and compare.
-phaseshift is not recommended if source is ac3 because the surround channels are already phaseshifted, if you do other phaseshift the result was wrong.
-normalize is the parameter recommended after a downmix to obtain the max volume, instead the arbitrary +6dB

I gather DRC is a good thing since it lessens the difference between loud things such as bangs and normal speaking, so when increasing the volume so I can hear them speaking (I'm slightly deaf) it won't blow the family away when a bang occurs... is that right ? and if so, can we do DRC with eac3to ?
DRC is a good thing when play the audio, but use it to reencode is lose quality. If you play with PC you can use AC3Filter to add DRC on the fly. If you use receivers there are a 'night' mode to play.

Now eac3to don't decode with DRC activated and Aften can't do correct DRC management.

I think there is a small bug in EAC3to way of parsing the mpls files and the m2ts files.

I did a test on Der Untergang (Nordic version)


just to see which mpls and m2ts files are used...

d:\eac3to>eac3to "H:\"
1) 00007.mpls, 00010.m2ts+00009.m2ts, 2:35:23
- Chapters, 12 chapters
- h264/AVC, 1080p24 (16:9)


------------------------------------

d:\eac3to>eac3to "H:\" 1)
M2TS, 1 video track, 2 audio tracks, 4 subtitle tracks, 2:35:23, 24p
1: Chapters, 12 chapters

3: AC3, 5.1 channels, 448kbps, 48khz, dialnorm: -27dB
4: DTS Master Audio, 5.1 channels, 24 bits, 48khz, dialnorm: -4dB
(core: DTS, 5.1 channels, 24 bits, 1509kbps, 48khz, dialnorm: -4dB)
5: Subtitle (PGS)
6: Subtitle (PGS)
7: Subtitle (PGS)
8: Subtitle (PGS)
v02 The video framerate is correct, but rather unusual.

Here we dont have any names on the subtitles, there should be, because when I open the mpls files in text mode I see this:

MPLS0200 :

deu = Deutsch (German) (Audio)
dan = Danish (Subtitle)
nor = Norwegian (Subtitle)
swe = Swedish (Subtitle)
swe = Swedish (Subtitle) (Should have been Finnish, mastering error on the bluray, not eac3to fault)

But as you can see the mpls language/Subtitles are NOT always parsed and shown in eac3to. BUG!

---------------------------------------------
If I then try to parse the 2 m2ts files I also dont get any subtitle/language and I think its because eac3to only parse the first file begin 00010.m2ts which is a 1 sec long black screen video clip without audio/subtitles.

d:\eac3to>eac3to "H:\BDMV\STREAM\00010.m2ts"+"H:\BDMV\STREAM\00009.m2ts"

5: Subtitle (PGS)
6: Subtitle (PGS)
7: Subtitle (PGS)
8: Subtitle (PGS)
v02 The video framerate is correct, but rather unusual.


---------------------------------------------
If I then skip the 00010.m2ts file and go for the 00009.m2ts which is the main video, it shows all the language and subtitles as indicated in the mpls file. GOOD!

d:\eac3to>eac3to "H:\BDMV\STREAM\00009.m2ts"
M2TS, 1 video track, 2 audio tracks, 4 subtitle tracks, 2:35:21, 24p

4: Subtitle (PGS), Danish
5: Subtitle (PGS), Norwegian
6: Subtitle (PGS), Swedish
7: Subtitle (PGS), Swedish
v01 The video framerate is correct, but rather unusual.



There is also a problem with extracting video and audio from this using the mpls file. Because the audio goes out of sync because of the small 00010.m2ts black screen file. Giving you this when extracting:


d:\eac3to>eac3to "H:\" 1) 4:"D:\Audio.dts" -core
M2TS, 1 video track, 2 audio tracks, 4 subtitle tracks, 2:35:23, 24p

5: Subtitle (PGS)
6: Subtitle (PGS)
7: Subtitle (PGS)
8: Subtitle (PGS)
v02 The video framerate is correct, but rather unusual.
a04 Extracting audio track number 4...
a04 0:00:00 Detected PTS break, increasing PTS by 41.7ms...
a04 Extracting DTS core...
a04 Removing DTS dialog normalization...
a04 Creating file "D:\Audio.dts"...


The audio is out of sync by 1-2 sec. The solution is to rip the files from the 00009.m2ts files (main movie) then the audio is in sync. Dont know if eac3to can make a work around for this.


Last a small request if possible. If you want to extract the chapters, is it then possible to do this without having eac3to to scan the video stream. As the chapters are located in the mpls file ?

yhe, you're right about 1) it makes alote of sense, I did know what I was talking about, but it was 2), dithering is right, but I didn't mention it for that reason.

so if three is no way to disable second pass, is the last version without 2nd pass still available ?
Here's the best place I know of that has older versions still available.

@Madshi...

is this a bug (http://forum.doom9.org/showthread.php?t=125966) ? Processing a HD-DVD, giving an explicit name eac3to accepts it, writes it in the log:

command line: "C:\Program Files\eac3to\eac3to.exe" "E:\" 1) 2: "C:\Temp\Batman Begins\Chapters_2.txt" 3: "C:\Temp\Batman Begins\Video_3.*" 6: "C:\Temp\Batman Begins\Audio_6_Undetermined.THD+AC3" -LOG="C:\Temp\Batman Begins\eac3to_PASS3_LOG.LOG"

madshi,

can you compare these flac files created by eac3to?

http://www.sendspace.com/file/scv0kk

The method:
Extract mlp+decode to wav with DVD-Audio Explorer 2008.07.21 (Beta3) by MaximA and retransmit to flac via eac3to.
eac3to\eac3to C:\users\rica\desktop\tracs\E.wav C:\E\E_01.flac

The original audio track has a constant bit depth of 24 bits.

Done.
It is perfect.

It has problems; i think channel mapping issue.

[peterjcat]

but actually writes :

Audio_6_Undetermined DELAY 200ms.THD+AC3

It's not a bug, it's a feature! It's telling you, in a way that makes sure you don't forget it, that you need to delay that audio track 200ms when you are muxing it (eg using tsMuxeR). eac3to can't apply TrueHD delay itself so you have to delay the whole track when muxing, or it will be out of sync.

[peterjcat]

@sixt, you're doing a very long winded process with out dated software. drop EVOdemux, get tsMuxeR v1.8.18, wait for eac3to 3.12 (that fixes the HD-DVD stream language issue) and try again.

for a very comfortable solution to what you're trying to acheive.

This is true, nobody uses EVOdemux anymore, eac3to will do everything faster and better. Keep in mind that you'll never get your WDTV to play TrueHD (or DTSMA) because, as mentioned, it doesn't have the right connections.

Your best bet would be to convert the TrueHD losslessly to an LPCM stream using eac3to (or one of the tools that use it, maybe the above, maybe ToNMT?). The WDTV should be able to support multichannel LPCM over HDMI. You say you've tried that but you don't say what exactly you've tried and what exactly's happening.

Of course, if you're not using eac3to, there are other places that should be able to help you better.
