@kukushka
Maybe we can open a new thread to speak about AAC and muxer/demuxer's (Mp4Muxer/Mp4Box/MkvToolnix/tsMuxeR), but the relevant questions for this thread are clear: - The directshow Nero 7 decoder, used by eac3to to decode .aac, cut the first 1024 samples (21,333 ms in 48 KHz) in 2.0 and is broken for 5.1. Take in mind the problem. EDIT: after more test the cuts are unpredictables (from 0 to 54 ms) - The encoder NeroAacEnc.exe, user by eac3to to encode .m4a, put the correct delay to compensate and can be decoded without problems with NeroAacDec, Qaac or ffmpeg. No problem with it. - eac3to works fine extracting AAC from MKV/TS/M2TS containers, I obtain the same aac than I muxed previously. Then, to avoid problems, you can use eac3to to extract and Qaac or ffmpeg to decode (or LWLibavAudioSource inside AviSynth).

Hi, folks. I purchase bluray and get this errors with eac3to:

did you check the playlist file of how many .m2ts files it consists (the file itself, not what eac3to displays)? perhaps the main .m2ts file is preceeded by some other small .m2ts file which has a 5.1 channel configuration.

Over the last few months I've been backing-up all my multi-channel (DVD-A, Blu-Ray Audio and DTS-CD) albums to single multi-channel flac files complete with a cue file.
All had been going very well up-until this morning, when I tried to back-up my 'Don Henley - End Of The Innocence' DTS-CD. After some investigation I've determined that the problem lies with the disc's very first track, which has been encoded using 6.1 DTS-ES audio, instead of regular 5.1 DTS audio. So far I've managed to back-up the first track to a (52.6MB) dts-es.wav file. And I've also managed to extract the elementary (46.0MB) dts-es.dts stream - but now I'm stumped Ideally what I'd like to do is create a 5.1 channel flac file from the 6.1 channel dts-es source but sadly neither LameXP or UsEac3to (with eac3to v3.31) are able to do this. Does anyone have any ideas? EDIT: Here's a link to a 5 second DTS-ES sample

Yes, I used playlist and mt2s. From playlist can only extract dts files, with m2ts can extract and transcoding but I never get audio 5.1 only 2.0. Is posible that this company had hack playlist for showing false dts 5.1?

Where is it showing false information?
The first m3ts contains 5.1 audio, the second 2.0. If you extract the playlist the header at the beginning will come from the first file and show as 5.1. If you only extract from the second m2ts it will always show as 2.0, because that is what is in the file. There is no 5.1 to decode, unless you like the intro in the first m2ts enough that you'd like to keep it. Your options are to ditch the intro, or downmix the sound from it to stereo and prepend it to the audio from the second m2ts file. |

And can not it done intentionally?? Company sold product like DTS-MA 5.1: http://www.amazon.es/Dragon-Battle-E...VR19TT8QQ27FWS (Pre-sold that I got)
I am refering to false info to:

in that case you could try to contact the company and tell them about it & complain, get a refund etc.

I actually tried these command line parameters with UsEac3To but I get this warning: -

Then you need split your dts in 2 parts, only the first one need the -down6 eac3to 1.dts 1.wav -down6 eac3to 2.dts 2.wav After you can concatenate the 2 wav's: sox 1.wav 2.wav full.wav And encode to flac: eac3to full.wav full.flac The problem now is split the dts. Like "Aborted at file position 1310720", maybe you can upload me 2MB and I can say you how split the dts: eac3to full.dts begin.dts -2mb

Here's a link to a 10 second DTS-ES sample. And another to the full dts-es file. Cheers

@SeeMoreDigital
Is not so easy, the dts is corrupt and there are 37 frames along the full dts (13460 frames) with the BC channel unrecoverable. eac3to crash decoding with dcadec and Arcsoft. With libav produce 346 WARNINGS and the decoded wav is useless. I have succes with BeHappy decoding the dts to wav 6.1 with: LWLibavAudioSource("D:\tmp\input.dts", stream_index=0,cache=false) than use dcadec also. Here I see the 37 broken frames decoded as silence. Using Foobar2000 I get a wav 5.1 with the BC channel already mixed in BL-BR. Sound fine for me: https://www.sendspace.com/file/lw3fl1

So the actual dts-es elementary stream is at fault. Do you think this could this have happened when it was extracted from the .wav container using DTSParser v2. Or somewhere else? Thanks again
