DTS in an AVI file

maormini · 2nd December 2002, 12:39

I searched the forum up and down, went through alot of posts but there is still no answer whether it's possible to extract and then mux a DTS sound stream with a DivX encoded avi file!

Is it possible at all, and if so PLEASE give me the method!

rjamorim · 2nd December 2002, 14:03

Well, I guess possible to mux it is.

But there's no way you'll be able to playback this AVI. (Unless you maybe use InterVideo Platinum... it can playback DivX, and DTS, but I wonder if it can playback both at once... humm...)

If someone could provide me frameheader specs of DTS, then I could try to implement DTS support into AVI-Mux GUI!

Afaik, Intervideo AC3 filter can playback DTS, so this should not be the problem.

Implementing DTS support for AVI is senseless anyway. DTS has such high bitrates (768kbps and more) that it just doesn't make any sense to mux it with an AVI. You won't go under 3-CD-Rips if you wanna use DTS

depending on the lenth of the movie i could also b a 2cd rip
and for some movies it would definitivle worth it

Why do you speak in sizes of CDs actually? What about putting 2 divX movies onto one DVD-R?

E-Male · 3rd December 2002, 00:43

well, i cross fingers this will work

DJ Bobo · 3rd December 2002, 13:09

@ alexnoe
Good point! never thought about it... (don't have a DVD-R burner)

alexnoe · 3rd December 2002, 13:11

But you certainly want one

DJ Bobo · 3rd December 2002, 15:37

Oh yeah! if you lend me some money

alexnoe · 22nd December 2002, 13:21

I got hand on a DTS frame header description which seems to be accurate enough to add DTS support to AVI-Mux GUI.

Problem: The AC3fromAVI-filter will send it as AC3 to the decoder (it seems to interprete a wFormatTag of 0x2000 as AC3), which therefore does not replay anything (already tried it).

Since I have absolutely no knowledge on DirectShow programming: Could someone modify the AC3fromAVIfilter either to handle both DTS and AC3 (and add a new wformattag, such as 0x2001), or create a DTSfromAVI filter (also using a new wformattag)?

Sorry for the useless post of mine, but I really hope that someone will help you because it will be really great if we can make/play avi with dts sound.

gabest · 26th December 2002, 13:38

Of course it would be possible, but do you know a filter which would transform DTS into wave samples for the avi muxer with this new id on the media type? Not that it was hard to make such too.

Ah, and one more thing, the current ac3 decoder filters accept wave with id=0x2000 natively, but they don't know about our new id for DTS.

The problem is about the player, not the muxer. AVI-Mux GUI does not use any of this broken DS filter stuff.

What I want someone to make:
=> a DTSfromAVI filter, which works the same way as AC3fromAVI, just with another wFormatTag
=> a new filter which passes DTS audio over to intervideo decode, but which tells the decoder that it is DTS. Currently, it is passed over as AC3

I see, it should work as you say. Last question, what's the media type of DTS? The one to set at the output pin of the DTSFromAVI filter.

I don't know, but why not use graphedit to find it out?

Maybe you can parse a vob file containing DTS audio with graphedit and then just look up the media type.

any progress-reports alexnoe?

Suiryc · 30th December 2002, 20:44

Last time I had a look into mmreg.h (where common tags are defined).
What is the WAVE_FORMAT_DTS (0x0008) value (wFormatTag) for ?
Even with this name I am not sure this is related to Digital Theater Systems because the comment next to it is 'Microsoft Corporation' ...

Mango Madness · 31st December 2002, 00:16

I would much rather see decoding of DTS so that we can have a cleaner source for mp3, ogg, or AAC compression. oh how i'd love to have a 6.1 channel 24bit wave file to have and to hold.
