I posted this mail a few days ago on the quicktime list but was since

are any takers here.
Personally I tend to monitor the QuickTime API list more frequently, if that matters....
We are about to switch from standard quicktime to QTKit in our
application, so I'm still getting familiar with the new API and I
might have missed something in the documentation. What I'd like to
know is, whether there's a way to add a QTTrack to a QTMovie, I
couldn't find anything in the QTKit reference docs.
As I currently understand it, the procedure seems to be a) create a
QTMovie, b) get the QTMovie quicktime movie, c) create a new track
with NewMovieTrack and d) use that track to initialise a QTTrack.
That's the correct sequence of steps in QTKit 1.0.
Is that right? And if so, what's the rationale in leaving out an
-addTrack: method in QTMovie?
QTKit 1.0 was designed to provide a solid playback engine and to make it easy to open and display QuickTime movies, as well as to perform basic manipulations on movies. We purposely tried not to bite off more than we could chew. I expect that additional methods, such as some flavor of addTrack, will appear in later versions.
Just for my own edification, what would an addTrack method look like, in your opinion?
