cocoa-dev:

While the  CocoaDVDPlayer sample works fine for basic playback of a dvd or
VIDEO_TS folder, it isn't very helpful when trying to go a little further.

Specifically, I need to be able to have DVDKit draw the video into a
gworld or other offscreen buffer so that I can draw it in a view in my
application's window, allowing the window to contain other content.
There's a DVDSetVideoPort(), which I thought I would be able to pass a
gworld too, but it looks like it needs a display device id as well, as
though it's trying to force the dvd content to be drawn only in an
onscreen window. Also, since I can't debug the app (quits with error 45
when run with gdb, I assume this means "licensing prevents debugging of
dvd apps"), it makes it hard to figure out what's going on.

Furthermore, I'd also like to have more access to the actual video, such
as to find the number of samples (frame), and the locations of keyframes.

Has anyone had any luck with this?

Thanks,
Devin Lane
