-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)

Quote:

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
2: h264/AVC, 1080p24 (16:9)
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 : p 2 P00010M2TS ›üÀ\P . b ‘deu °00009M2TS ›üÀœw³ Ž b adeu †adeu dan nor swe swe ‘deu $ 00008M2TS ›üÀœ ª ›üÀÿÿ Bóÿÿ %iÿÿ (*Õÿÿ Gµ'ÿÿ .“ÿÿ
Þ6ûÿÿ Ÿ3ÿÿ SÙHÿÿ ;½/ÿÿ †
‚ÿÿ >Íÿÿ

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"
M2TS, 1 video track, 2 audio tracks, 4 subtitle tracks, 2:35:23, 24p
1: Chapters, 12 chapters
2: h264/AVC, 1080p24 (16:9)
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.

---------------------------------------------
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
1: h264/AVC, 1080p24 (16:9)
2: AC3, German, 5.1 channels, 448kbps, 48khz, dialnorm: -27dB
3: DTS Master Audio, German, 5.1 channels, 24 bits, 48khz, dialnorm: -4dB
(core: DTS, 5.1 channels, 24 bits, 1509kbps, 48khz, dialnorm: -4dB)
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:

Quote:

d:\eac3to>eac3to "H:\" 1) 4:"D:\Audio.dts" -core
M2TS, 1 video track, 2 audio tracks, 4 subtitle tracks, 2:35:23, 24p
1: Chapters, 12 chapters
2: h264/AVC, 1080p24 (16:9)
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.
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 ?

Here's the best place I know of that has older versions still available.

@Madshi...

is this a bug ? Processing a HD-DVD, giving an explicit name eac3to accepts it, writes it in the log:

Code:

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"


...

[a06] Creating file "C:\Temp\Batman Begins\Audio_6_Undetermined.THD+AC3"

but actually writes :

Code:

Audio_6_Undetermined DELAY 200ms.THD+AC3

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.

Code:

eac3to\eac3to  C:\users\rica\desktop\tracs\E.wav C:\E\E_01.flac
------------------------------------------------------------------------------
WAV, 5.1 channels, 0:06:32, 24 bits, 13824kbps, 96khz
Reading WAV...
Encoding FLAC with libFlac...
Creating file "C:\E\E_01.flac"...
The original audio track has a constant bit depth of 24 bits.
eac3to processing took 1 minute, 30 seconds.
Done.

It is perfect.

_ _ _ _ _ _ _

http://www.sendspace.com/file/8snz93

The method:

Extract mlp directly with DVD_Audio Explorer and transmit to flac with eac3to.

Code:

eac3to\eac3to  C:\users\rica\desktop\tracs\E_new.mlp C:\E\E_new.flac
------------------------------------------------------------------------------
MLP, 5.1 channels, 24 bits, 96khz
Decoding with libav/ffmpeg...
Encoding FLAC with libFlac...
Creating file "C:\E\E_new.flac"...
The original audio track has a constant bit depth of 24 bits.
eac3to processing took 2 minutes, 12 seconds.
Done.

It has problems; i think channel mapping issue.

EDIT: Here is the extracted original mlp (by method2):

Any progress with DTS-HD MA 7.1 support? N/M see I need the arcsoft decoder to get this..

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.

Please see here:
eacto, tsMuxer & ImgBurn Made Easy

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.

I hear, no pun intended, that flac is a better lossless choice. Please correct me if I'm wrong.

I have never added a delay and has been in sync everytime. As soon as tried adding the delay (one was 1001ms) the sync was way off.

Yep, seems the remap needed is missing (or now libav is correct and don't need remap).
We have problems with 18,19 and 20 modes

Code:

 # MLP Channel Assignments    MS channels order   libav remap

Ok got arcsoft decoder seemed to decode dts hd fine to pcm but when remuxed with tsmuxer channels are mixed. the right speaker is playing the center channel when playing pcm.

this may be a issue with PCM2tsmu not sure but i did use the -c 8 switch with it and tsmuxer does say 7.1.

FLAC is indeed a better (more efficient) choice IF you have a device that will play it back, such as a PC. The OP wanted to hear lossless audio on his WD TV and there's no way that's playing back multi-channel FLAC. However, it should play LPCM as there's no decoding involved. The recommendation was just for those circumstances.

Just a quick note that I've now added Blu-Ray support to HDConcertRipper. This is the last post I'll make about it in the eac3to thread, anyone interested can continue the discussion in the official thread.

A delay specified in the filename like that, or just a delay reported when eac3to is running? eac3to fixes the latter delays, doesn't fix the former. And I guess sometimes it might put a delay in a filename when it doesn't need to, I'll let madshi speak to that, but believe me it's there for a reason.

No, it says it plays FLAC music. It doesn't support FLAC in movies, let alone multi-channel FLAC in movies, let alone decoding multi-channel FLAC in movies to LPCM for lossless output via HDMI.

Hmm why does eac3to remap channels when using arcsoft decoder to get a pcm file? seems to be a bug in the channels for 7.1 as the center is playing out of right front.
