Doesn't work with version 1.1.0.8 (the one I have). I get the following log output when I try to decode a 6.1 DTS-HD track:

[a03] The ArcSoft and Sonic decoders don't seem to work, will use libav instead.
[a03] The libav DTS decoder doesn't decode the back channels. <WARNING>
[a03] The libav DTS decoder doesn't decode the full DTS-HD information. <WARNING>

Since 1.1.0.8 supposedly can't handle 6.1 DTS it could be related that bug.

Is there any other way to decode 6.1 DTS?

Doesn't seem related to eac3to specifically, I can't get the decoder to work with Media Player Classic Home Cinema either.
Is this really the only way to access a 6.1 DTS stream?

Getting the following error trying to convert 6.1 channel DTS-MA to LPCM:

a03 Blu-Ray PCM doesn't support 6.1 channels. Will upconvert to 7.1.

This is, in itself, normal, except that I had a commandline like this:

"eac3to 1) 3: c:\video\temp.pcm -down6"

Since I'm downcoverting to 5.1 anyway, it seems wiser for eac3to to do so directly, instead of upconverting to 7.1 first.

tebasuna51

"eac3to 1) 3: c:\video\temp.pcm -down6"

Yes I can confirm the bug, work with other output but not with pcm. But isn't the problem, the problem is:

One more time, the eac3to -down6 with 6.1 sources don't work fine, the surround channels have a bad mix.

You need:
eac3to input_6.1 output.wavs

and make the mix manually:

SL' = SL + 0.7071 x BC
SR' = SR + 0.7071 x BC

Thunderbolt8

6th September 2011, 12:20

is there actually any list of bugs which eac3to currently has with 3.24? and maybe also a list of known limitations in regards to other tools like arcsoft etc. (apart from those mentioned at 1st page)?
would be nice if someone with an overview on these things could create such a list, I myself always keep losing track of such things.

might be easier then just to refer back to a certain post which can be kept up to date.

So, I guess I was 'lucky' then, in my case of pcm, that it upconverted to 7.1 first, mix-wise? (assuming downconvert from 7.1 goes fine too).

Sorry but the upmix to 7.1 is also wrong because make:

BL' = 0.7 x SR
BR' = 0.7 x SR
SL' = BC
SR' = SL

and after, if you use the -down6, obtain:

SL'' = BC + 0.7 x SR
SR'' = SL + 0.7 x SR

tebasuna51

To avoid the bug we can use a fake remap like this:

eac3to input_6.1 output_5.1 -0,1,2,3,5,6,4 -down6

where input_6.1 can be a DTS 6.1 track, and output_5.1 can be ac3, wav, w64 ...

Edit:
This remap is also needed to upmix 6.1 to 7.1 with the -double7 parameter:

eac3to input_6.1 output_7.1 -0,1,2,3,5,6,4 -double7

tebasuna if I pipe eac3to to another encoder (qaac for example) and set it to -normalize (creating an intermediate wav) and -down6, does this mean 6.1 DTS sources will have a wrong surround channel mix? or is it only when using the .pcm extension? Or is it literally every time you downmix 6.1 to 5.1, no matter what decoder and what output?

tebasuna51

No matter the source/decoder or encoder, when you downmix 6.1 to 5.1 with eac3to need use:

Since jruggle sais libav is now better than aften (quote: http://forum.doom9.org/showthread.php?p=1522077#post1522077),
how is it possible to use libav with eac3to for AC3-encoding?

nurbs

11th September 2011, 14:22

Either let eac3to save a wav and reencode that with libav or pipe the output of eac3to to libav. You can do the latter by adapting this:
eac3to.exe "C:\Movie" 1) 3:stdout.wav | qaac.exe --tvbr 100 --quality 2 --rate keep --no-optimize -o "output.aac" -
You'll have to adapt that for libav, but the most inportant thing is to tell eac3to to output to stdout and to tell the encoder to read from stdin (which works by using "-" as the input in qtaac).

Just tried this on a DTS-MA 6.1 source, and eac3to still upconverts to 7.1 first (because I remap to pcm). I guess I should map to wav then first, right? (that obviously doesn't trigger intermediate upscale phase).

I always convert DTS-MA/TrueHD to LPCM, as I use my PS3 as media server, and it can't stream DTS audio; so, for my HD audio needs I require a LPCM track.

how is it possible to slow down video and audio of a 50p input file (the source is 720p50)? fps rates of video and audio get changed to 23.976 fps instead of 48p, and of course the output files have ~double the runtime of the input file and sound is ultra slow.

If you play a 7.1 track on a 5.1 speaker setup (or if the studio downmixes 7.1 to 5.1) the 5.1 surround channel pair usually contains a mix of the 7.1 SR/SR and BL/BR channel pairs.

Sat wha?! All my life I've been manually downmixing 7.1 tracks to 5.1, thinking I'd otherwise lose 2 channels on playback; and you're saying that isn't even necessary? That's interesting, if the case.

If so, will a 7.1 LPCM track play as 5.1 (without losing channel info) as well?

Thanks.

Just ran across this message while processing the Thor Blu Ray:

DTS Master Audio, 7.1 (strange setup) channels, 24 bits, 48kHz
(core: DTS-ES, 5.1 channels, 24 bits, 1509kbps, 48kHz)
CAUTION: Decoding this track with ArcSoft results in low volume.
Decoding with ArcSoft DTS Decoder...
Encoding FLAC with libFlac...

Searching this thread, I found a good explanation by madshi here (http://forum.doom9.org/showthread.php?p=1216107#post1216107), but the last mention of the message was also dated back in 2008. The version of Arcsoft I'm using is quite old (like from around 2008), since I only use it for decoding DTS Master Audio files with EAC3To, so I had no reason to update it.

So before I go getting a new version of Arcsoft, can anyone tell me if they fixed this little issue in later versions? Or worse, have they locked out their filters from third party programs like Nero does/did? Thanks.

AFIAK 1.1.0.0, 1.1.0.7 and 1.1.0.8 all have the same problem. The only solution is to use the Sonic decoder, but it only supports 5.1 so you will have to downmix if you have a 6.1 or 7.1 source. If you are downmixing from 6.1, you will need to use this in the command line as per tebasuna51's instructions:

Personally, I can't say this 'problem' bothers me a lot. In fact, I hardly notice it (and probably never would have if I hadn't known about it); and if I do, then I just tap the volume on my amp twice to up the volume a bit. I mean to say, don't think you're going to get an extremely low volume.

The way it stands, most of my Blu-Rays play at different volume levels.

If you are downmixing from 6.1, you will need to use this in the command line as per tebasuna51's instructions:xkodi found out that the sonic decoder decoder drops the XX channel extension and produces a bit-perfect correct 5.1 automatically in case of strange setup(!) 7.1 DTS-HD MA tracks which includes all the channel information and nothing gets dropped. so there should be no need to downmix to 5.1

Thanks for the tips guys. I played my FLAC version last night and didn't notice much drop in volume compared to the DTS Core file I also extracted. I guess if you want it to be truly lossless, the best thing to do is just bitstream the original DTS-MA soundtrack to a receiver. Since I don't have one of those yet, I'll just keep converting to FLAC.

You guys mentioned version numbers like 1.1.0.0, and I think Arcsoft is up to version 5. I'm guessing you're referring to the version of the DTS decoding filter. How can I check what version mine is? Thanks.

There are some differing opinions as to which versions decode properly.

Personally I use 1.1.0.0 for 5.1 and 6.1 DTS-MA, and I use 1.1.0.8 for 7.1 DTS-MA (except strange setup). This is because of this post:

Yes, we need switch in this situation.
In case of non-standart scheme decoder 1.1.0.0 give garbage in some channels. So, i tried other two versions and they are decoded properly. If you have DTS-HD M.A.S. you can try yourself. If not, try decode test sample (http://www.mediafire.com/?kagbxe5zg7tdzg0) of DTS-HD 7.1 (scheme 2) and compare results.
AFAIK, there are only two differences between 1.1.0.0 and 1.1.0.8:
- 1.1.0.0 can decode DTS(-HD) 6.1/6.0 but can't decode non-standart 7.1
- 1.1.0.8 can't decode DTS(-HD) 6.1/6.0 but can decode non-standart 7.1
Both decode DTS(-HD) 1.0 correctly, unlike 1.1.0.7.

However, I believe tebasuna51 has stated that he hasn't had any problems with non-standard 7.1 sources and Arcsoft 1.1.0.0.... So I don't know what to tell you. I use the different versions just to be safe.

For 5.1 content Sonic is identical to Arcsoft AFAIK, but it automatically downmixes 7.1 content to 5.1, and doesn't work on some 6.1 content. For 7.1 Strange setup you will want to use Sonic anyway because like Thunderbolt8 said, Arcsoft doesn't decode it quite right.

The Sonic DTS decoder is very good for DTS, DTS-ES, DTS-96/24, DTS-HD Master Audio and DTS-HD High Resolution tracks. The only problem is that it decodes DTS-HD 7.1 tracks only as 5.1. Most DTS-ES and DTS-HD Master Audio 6.1 tracks are fully decoded as 6.1, though.

So if you mix everything down to 5.1 with eac3to, then Sonic should be fine. And in the case of downmixing 6.1 to 5.1 Sonic works properly even without specifying the correct channel map, as stated 4 posts above.

For 7.1 Strange setup you will want to use Sonic anyway because like Thunderbolt8 said, Arcsoft doesn't decode it quite right.

does eac3to decode and reencode the DTS-HD MA track at all when you are just demuxing it or does it just extract a 1 to 1 copy of the track without doing anything to it?

I believe that you may have to register the ARCsoft filter. I don't think the ARCsoft installation does this and I know that the LAV Audio filter handles it a different way and doesn't need registration.

That's write. The checkactivate.dll was installed with previous version of TMT. The checkactivate.dll is only needed for
eac3to, TMT 3 doesn't need it to function. Eac3to check's if this file is installed, if not then eac3to will not use TMT.
Get hold of an older version of TMT (I think version 2) and extract the checkactivate.dll
