Support forum for DG Tools

It's since a while that I noticed this thing but I always forgot to report.

When 7.1 audio is found, DGIndex marks it as (example) […] C+L+R+SL+SR 48 […] like a 5.1 audio.

Is it possible to have it fixed?

I'll have a look but if it is beyond me we'll have to wait for Rocky to get better.

It's not an easy thing to do in the current design. The audio analyzer works at TS packet level and when we see a DTS frame header we grab the parameters from that header (contained in the current TS packet). The parameters are for the core stream. If there is an XXCH extension that signals 7.1 it is located after the core audio and many packets later in the stream. There is no way currently for the code to jump ahead and scan for the extension syncword. We could add a new parser that steps through packets looking for one with the audio PID and containing an extension syncword but it is non-trivial and a lot of work for something that is not super important. You have MediaInfo and other ways to determine the nature of the audio. Not saying we'll never do it but it's not high priority.

Thanks for the analysis, Bullwinkle. I was able to hack up an attempt at this. Please download and test this:

For both the audio list in the GUI and for the demuxed file name, it should show either 5.1 or 7.1. For anything else nothing is shown. Can change things if needed. Let's see if it breaks anything and covers all the cases.

Bravo, Rocky! Where there's a will there's a way.

Welcome back! I will try ASAP!

Tested and working.

Thanks!

You're welcome. Thank you for your report and testing.

I just noticed that there is a double space in the generated filename, between the pid number and the channels count:

orion PID 1100 5.1 48 1536 jpn DELAY 0ms.dts
night PID 1100 5.1 48 1536 jpn DELAY 0ms.dts

Thank you big t. I've fixed it locally for the next slipstream.

I don't know if there is a regression with last release or it was an issue already present.

I have just noticed that in the mpls preview I get:



In the Demux panel however it reports the correct number of channels.

I tested both with Top Gun Maverick and Minions 2.

EDIT: While converting the audio I got the following error:

pcm_to_ddp: Check input and downmix config. Resulting output channels: 0 is not allowed. Valid value(s): 8.
pcm_to_ddp: Check input and downmix config. Resulting output channels: 0 is not allowed. Valid value(s): 8.

Does DGIndexNV place the channel number somewhere or it alters the header in some way? Never saw that error, ever.

Does DGIndexNV place the channel number somewhere or it alters the header in some way?

No to both so please provide a link to purchase a disk that behaves that way.

BTW, that data in the Choose MPLS dialog comes from DGDemux.

How are you "converting the audio"?

Funny part is that the demux panel shows them correctly.

ffmpeg decode to w64, then Dolby Encoding Engine thru DEEW-

I have found that last stable release of ffmpeg (but not the last nightly, that I was using) can decode them correctly.

Link is for pre-order and it gets released tomorrow. How can you already have it?

Not every shop respects embargo.

Disk ordered.

I have found that the BDs of the first two Evangelion movies have 6.1 DTS audio.

It's recognized as 5.1 by DGIndexNV.

A small sample:

Yeah, I know. Samples are very useful. Investigating...

Maverick is here. Ripping...

I released a fixed DGDemux for your THD "0ch" issue. I want to fix the 6.1 showing as 5.1 first before looking at your Cowboy Bebop stuff. Regarding DGCube internal conversions, honestly, I just can't get motivated it for it right now. Maybe later.

@Guest 2

I can't download your Evangelion sample as all browsers say it is blocked as a virus. Can you put it on my FTP?

Believe me that a LOT of people are waiting for it.

If the good guys win tonight I'll try to raise the priority. Think about stopping to ask for other things while waiting for it.

I saw Sherman googling "dress and cook squirrel". I knew inflation was bad but have we gotten that far? Frogs can't be too far behind. Right?

To be safe you have to be at the top of the food chain. Like me.

Sorry about the UPS, Rock. Nobody ever told me you shouldn't run a space heater off it. Who knew?
