Richard,
the usual format is to have a folder called VIDEO_TS that contains
one or more VOB objects. VOB are nothing but a fancy packing for the
dvd media files. The standard encoding for DVD is MPEG-2 video, the
Audio I think is AAC or something... but both are pretty standard,
like, Rev Player will be able to play them. The trick thing is to
unpack the VIDEO_TS VOB files. I think you could opt for some ways:
(1) Use some F/OSS project to unpack the VOB files on the
background in your app and then load them on a player object. There
are many projects on sourceforge to deal with VOBs. Don't really know
how much time it takes to do that, but it should not be long since
you can't really do much number crunching with MPEG2 files and expect
that consumer DVD players will be computing-wise enough to deal with
it. I even expect VOBs just to be some concatenation of the files
with a TOC but I really don't know.
(2) Use some F/OSS project to spawn a player window and play the
thing. That's the approach taken by many players on VersionTracker,
the popular MPlayer OS X does just that, and it works. But I think
you might have some trouble bundling GPL apps with commercialware,
look for a BSD licensed one and be happy.
(3) Do you know in advance what DVDs you'll have to play? is
this like training material with a rich client? if so, please for the
love of consistency, just convert the DVDs back to MPEG2, burn new
DVD-ROM, load it in a player with no fuss. (but that may not be an
option...)
(4) AppleScript to the rescue!!! use applescript + Apple DVD
Player, just drive apples player!!! that's a hack, but we love hacks
don't we?
Cheers
