Audio-CD / VCD / SVCD / DVD

Hello,

I am making a virtual CD/DVD driver. I actualy made it… kind of. It
works just for Data CD-Roms. The problem is that I don’t know how to build
the response to IOCTL_CDROM_READ_TOC (for CDs) in case of Audio-CD, VCD
and SVCD. I do not need information about playing the Audio-CDs. I know
that I need to read raw data and play it using DirectSound… I think.
The DVD part is not yet implemented.

So, the problem is that after I mount a virtual audio-cd… windows
sais that nothing is in there… drive not found… etc. I just want to
return that “track01.cda, etc.” thing. I suppose what I need to implement
is the IOCTL_CDROM_READ_TOC.

Another problem is that I downloaded the ECMA-119.pdf specifications
file. But I do not find any information about Audio-CD / VCD / SVCD
format. Can anybody tell me where to find something like this?

Any information that could help me… documentation… sample
sources… links… anything, it would help me a lot. I need to finish
this in couple of days and I cannot get rid of this problems.

Thank you,
Ciubotaru O. Andrei

How about the CD-ROM class driver source code in the DDK and the ISO
specification?

SCSI spec lists the TOC layout for CDs. Look at www.t10.org

Thank you a lot Jamey! Sincerly, I looked over the samples in ddk, but it
never crossed my mind to look in the class driver folder. Plus, it’s the
real thing there.

Thank you,
