I avoided replying at first because your question might be
surprisingly complicated. :) But since nobody else has, here we go:
I don't think QuickTime provides a sleek way to get the current frame
number. What is really easy to do is to get the current time a movie
is set to. Is that sufficient for what you're trying to do?
For example:
float f = ((float)movie.getTime()) / ((float)movie.getDuration());
This yields a fraction from [0,1] indicating where you are in the movie.
If you really must have the frame number, that will involving digging
through specific tracks and media samples. Let me know if that's what
you're after.
Of course, if you have a specific usage in mind that always uses a
fixed fps, then it would be really easy to deduce the frame number.
