QTMovieLayer Class Reference

Overview

This class provides a layer into which the frames of a QTMovie can be drawn, and is intended to provide support for Core Animation, that is, drawing the contents of a movie into a layer. QTMovieLayer renders a QTMovie within a layer hierarchy. Note that this class requires rendering using visual contexts. Do not attempt to directly modify the contents property of an QTMovieLayer object. Doing so will effectively turn it into a regular CALayer.
