And there is also a package with azid.exe CLI decoders (P3/P4 opt.), but you may try to avoid intermediate files?
Doesn't matter anymore, anyway. See v3.26 release notes.

Thanks madshi for new version....however, Nemo 7.1 THD, decode to wavs, still fails lossless check :

Code:
[libav] Lossless check failed - expected 00, calculated f4.  <WARNING>
[libav] Lossless check failed - expected 00, calculated 65.  <WARNING>
[libav] Lossless check failed - expected 00, calculated f6.  <WARNING>
[libav] Lossless check failed - expected 00, calculated 88.  <WARNING>
The original audio track has a constant bit depth of 20 bits.
I've never seen the 20 bits depth before, besides this nemo track.

Edit: Correction, the previous libav (ver 3.25) would crash completely, while now it creates the wavs w/the warnings above. This is the same thing when creating flac via ffmpeg, so maybe it's a somehow corrupted stream.

Yes, slowdown-resample work over uncompressed audio data then eac3to must decode compressed audio before.

Is there still a need to remap channels when decoding DTS 6.1 tracks with Arcsoft decoder with latest eac3to.

The changelog is ambiguous if that has been fixed or do we still need to specify a channel layout?

Decode was always fine, only when you use -down6 was wrong.
And fixed now.

So I recently bought a bluray which has 16-bit, 96Khz TrueHD and 24-bit, 48Khz DTS-HD/MA audio tracks. My question is: if space is not an issue and playback will always involve decoding to PCM via arcsoft's decoder or the like, which track should I keep in the mkv encode?

Also, as a side question, if I will always play back from my computer then is it better to encode lossless audio from DTS-HD/MA or TrueHD to FLAC and maintain the original file's bit-depth and sample rate or should I just keep the original DTS-HD-MA/TrueHD file?

Seems than standard human ear can distinguise until 20 bit precission audio but not much over 20 KHz frequency (samplerate 40 KHz).

If your PC can send to receiver, through HDMI, PCM multichannel audio (decoded from FLAC or DTS-HD-MA/TrueHD) then the quality is always the same. Flac files have less size.

There are external players (PopCorn, Xtreamer, ...) than can send also Flac decoded to PCM multichannel.

I seem to be experiencing strange problems with some of my blu ray rips when converting Dts-HD Master to AC3 640 using eac3to

When playing back the m2ts files using Arcsoft player the audio says Dolby AC3 along with some odd kbps figures - 31kbps or 129kbps ect

Usually films just say Dolby AC3 in Arcsoft, i've even updated to the new version of Arcsoft and it still displays these odd numbers

When i ripped the Hunger Games which come out as 31kbps the audio sounded quieter compared to some of my other films so i have to turn up the volume a few notches

Checking the files though with mediainfo it shows the track as 640kbps English 48.0 KHz, 16bits, 6 channels, AC3 which is correct


Anyone else experieced this ? is this normal or is this a known problem with eac3to not converting the audio properly ?

I'm using the latest version of eac3to and arcsoft decoder 1.1.0.0

So the logging system is broken for you, but not for tebasuna51, nor for me.
Had the same behavior happen on a different system.

With the sample I've PMed you, simply running
Code:
eac3to part1.m2ts+part2.m2ts 2: test.flac
is enough to show the issue.

There is description of *.dtshd file in Annex E. Can you add header (and other chunks) to DTS-MA and DTS-HR file?
If examples of *.dtshd file are necessary, I can generate ones?

Vick...why would he want him to? If you're talking about *.dtshd files created by DTS-MA suite, that header is only used by authoring houses. For our purposes, we do NOT want the header to be there.

It can be easily removed by demuxing the track/stream via Tsmuxer. The resulting demux will have a *.dts extension, just like on a BD disc.

As a reminder, you still need to have a -21ms delay when removing .dtshd MA suite headers with EAC3TO, this bug didn't get fixed yet.

@jj, that's why I use Tsmuxer.

I think there are people who would like to decompress the DTS-HD files to .WAVs through the "official" StreamPlayer (simply because ArcSoft's DTSdecoderdll.DLL not always works as it should), and in this case too, the DTS-HD headers are mandatory.

Getting a line of output per second from the Nero encoder? Nero reporting every single second seems to be making eac3to think Nero is stuck. How can we disable Nero AAC encoder from reporting second by second processing?

You're right.
For StreamPlayer the header is necessary. And for re-authoring.

Try the workaround suggested in first post here:

eac3to S01E01.mkv 2: stdout.wav -downDpl | NeroAacEnc -q 0.5 -ignorelength -if - -of S01E01-downDpl.m4a
