That's what I do when I convert hd-dvd to BD with tsMuxer.

I guess that means that Tsmuxer wants an AC3 core for its TrueHD tracks.

HD-DVD TrueHD streams don't contain an AC3 core IIRC. In this case eac3to will generate the core if output.thd+ac3 is specified.

The problem is that the last option is NOT an option in Eac3to and More. Any suggestions for the program to extract that stream ?

You can do thd+ac3 in eac3to. Sounds like a GUI problem, not an eac3to problem, which have their own threads.

Anyone know if TMT3 decoders currently work in eac3to? Thanks.

did not work for me, so went back to tmt2....i don't think there is a differencein the decoder, but, in tmt3 it does not allow third party apps to make use of it....thats the last i knew anyway

I take it you have no problems with DTS-HD Master or PCM audio when demuxed and then remuxed?

My apologies for the very late reply on this. Been very busy at work.

No, I have no problem with TrueHD tracks if they are decoded to PCM, those work perfectly. Also have never had any problem with any flavor of DTS (DTS, DTS-HD, DTS-MA).

There are some TrueHD tracks that seem to work, but most give distorted audio. The distortion varies, and there are portions of the audio where you probably can't tell at first listen, and then there are sections where there is obviously something wrong.

I use the Iron Man BD to test this. The very first scene is majorly affected - the dialogue/discussion in the jeep at the very start of the film is barely audible under the eac3to.exe demux/TSMuxer remux scenario.

However, I have indeed finally solved this problem. It is indeed eac3to.exe's issue, and the root of the problem is the removal of dialogue normalization.

Eac3to removes dialogue normalization by default. When it does that, the sound is distorted when played through my Pioneer receiver.

Adding "-keepdialnorm" on the eac3to.exe command line has completely fixed the problem. I've tried my particularly problematic TrueHD track (Iron Man) which was very obviously distorted when played back after a demux with eac3to.exe and a remux with TSMuxer. The TrueHD track now plays perfectly and identically to the original when the -keepdialnorm option is used during the eac3to.exe demux.

This must be something particular to Pioneer receivers, evidently they pay very close attention to the dialogue normalization metadata and get confused if the values are incorrect, missing, etc.

Is there a way to override the removal of the fullrange flag from h264 streams?

EDIT: Nevermind I found "-keepFullRange"

When I use eac3to to demux evo-Containers with the -demux switch, eac3to demuxes not all the streams (especially subtitles with ID: 28 and up).

Is there a way to fix this or can I demux multiple streams at once WITHOUT converting them?

picman1 · 1st July 2009, 19:47

After ready through some of the posts on talking about TMT 2 and 3 to use for converting DTS 7.1 to LPCM 7.1 it sounds like if I don't have TMT 2 I cannot use TMT 3 to do the convertion? If that is the case does anyone know where I can get a copy (buy) of TMT 2? Thank you

frenchglen · 1st July 2009, 20:55

Hey madshi and folks,

Is there a way to split an MLP file with eac3to if you have a cue sheet or somehow just typing in where (in time/samples etc) to split the audio file?

Thanks very much...Haven't used eac3to in a while - I can only imagine all the excellent new features since the last time I updated it!

Maybe eac3to try to encode a 6.1 flac but the decoder output (libav) is only 5.1

Try to decode first:
"C:\VID2EVA\tools\eac3to\eac3to.exe" "F:\BDMV\STREAM" 1) 3: "Z:\VIDEOS\Vid2eva.wav"
and encode to flac after:
"C:\VID2EVA\tools\eac3to\eac3to.exe" "Z:\VIDEOS\Vid2eva.wav" "Z:\VIDEOS\Vid2eva.flac"

But if you don't have the ArcSoft decoder you can't decode the DTS-MA and use flac like output is not necesary, you can convert the wav output to ac3:
"C:\VID2EVA\tools\eac3to\eac3to.exe" "Z:\VIDEOS\Vid2eva.wav" "Z:\VIDEOS\Vid2eva.ac3"
or extract the core DTS-ES, 6.1
"C:\VID2EVA\tools\eac3to\eac3to.exe" "F:\BDMV\STREAM" 1) 3: "Z:\VIDEOS\Vid2eva.dts" -core

This same call works on other 6.1 DTS-MA files though.

Maybe, but with "core: DTS-ES, 6.1 channels"?

picman1 · 2nd July 2009, 16:15

Ok. Since no one seems to know where I can get a TMT version 2 to decode DTS 7.1 to LPCM. Does anyone know if there is any other way to do this conversion without TMT 2? Thanks

Good point. I don't know if I've seen a DTS-ES 6.1 core with DTS-MA before.

ArcSoft Decoder in TMT 3.0 works as well with eac3to.
