A MovieVideo is actually any source that provides a sequence of video frames. That could include an AVI file, a digital camera, or an internet TV station.
The difference between a MovieVideo and a
MovieVideoCursor
is like the difference between a filename and a file handle. The MovieVideo just indicates a particular movie. TheMovieVideoCursor
is what allows access.Inheritance diagram
