Is it possible to get these encoded into the movie at the same time as
the sequence grabber does, or do I need to either insert media element
into the track (sprite overrides in this case) within some data proc
handler (that is called while the sequence grabber is working), or
insert a completely separate sprite track into the movie after the
sequence grabber is done?
I thought you weren't always grabbing pictures. So your data proc (if
you had one) wouldn't be called all the time anyway.
You probably need to install some kind of timer and get the mouse
position periodically. Or register for mouse moved event notification.
It is simplest to let the sequence grabber make the movie. If you save
the mouse positions in memory you can create the sprite track
afterwards. For audio/video sync you may also want to register the
video frame time stamps by the same means that you time the mouse
positions (some system clock like TickCount() or microseconds()).
