IFO Parser for Delphi?

[sundance]

For a DVD tool I'm writing (or should I say trying to write ;-)) I'm in the dire need of some IFO file parser for Delphi.
Is there some unit/class around for that job?
And, while we're at it, a way to get the number of frames from an Avisynth script would also come in handy (I found a VFW wrapper unit dated 1999, but I couldn't get the thing compiled with D5. Is there a newer one or another way of doing it?).

Well I have the exactly same problem: I need a basic IFO parser in Delphi for my own app.
As I didn't find any, I'm simply writing one myself :)
But wait, it will be a very basic one: Audio/Video/Subs Streams info and that's all.
If you're willing to wait for me to finish I'll give you the unit, and i you want to help ... you're welcome !

While searching the internet I found a good point to start the delphi IFO parser class: vStrip!
You can download the complete source code at http://www.maven.de/code and the zip also contains the sources for "vStrip_gui" that comes with a complete IFO parser. I could complile the complete package with D5 so I guess it's complete. And since vStrip has a very good reputation I think there should be very few bugs in it.
The only drawback is that there's not much documentation, so you'll have to work through the code...

Well, I'm done :) ... at least for calculation unit.
I just want to add a form to show how you call procedures and I post it, I think today or tomorrow .

[TaZ4hvn]

Finally I finished my IFO parser. I added a small form to show you how it works and let ppl play with it. Also I added some stuff so that it auto-find DVD drive and parse each IFO in it.
Let me know if it fits your need, if you want something more, different ...
I named it Tiny Ifo Parser 'cause it gives TIP :p

TaZ4hvn:
Can the information be used to check if the disc is NTSC or PAL?

I could use a delphi function that would return the disc type (PAL/NTSC), I've got so much on my hands that I haven't had the time to look into parsing the IFO data.

[TaZ4hvn]

Can the information be used to check if the disc is NTSC or PAL?
Yep, for sure, this is retrieved amongst other info,
You can use any code you want I don't care :)

There's some problem.

If there's two DVD discs, the program crashes. (I used one real disc and one daemontools mounted disc).

Each on it's own seems ok.

[TaZ4hvn]

thx for the report: i'll look into this ...

Any progress?

[TaZ4hvn]

Not yet since I was on hollydays :)
I'll work on it now. I also added two different timing for the chapters: duration (present in the first version) and offset from the beginning.
Expect an update today or tomorrow .

[TaZ4hvn]

sorry, I'll need few more days to look at this since I have some relative at home right now :)

[Blight]

Any update?

[TaZ4hvn]

yep ! Finally I found a couple of hours to work on it.
improvements are as announced:
- if you have several DVD drives, you can switch between them,
- chapters can be sorted either by duration or offset.
This is a quick hack I didn't tested that well, plz report :)

I'd like to look at this as well and try it.

But the links are not working.

[TaZ4hvn]

yes they are !
Just right click the url and choose save as.
A double left click will draw to a forbidden page, dunno why but that's the way it works :p
