Configuring Movie Data Export Components

Your component may provide one or more configuration functions. These functions allow applications to configure your component before the Movie Toolbox calls your component to start the export process. Note that applications may call these functions directly.

All of these functions are optional. If your component receives a request that it does not support, you should return the badComponentSelector error code. In addition, your component should work properly even if none of these functions is called.

These functions address a variety of configuration issues. Applications
can retrieve additional data from your component by calling the MovieExportGetAuxiliaryData function.

Applications can specify a progress function for use by your component by calling the MovieExportSetProgressProc function.

Applications can instruct your component to display its user dialog box by calling the MovieExportDoUserDialog function.
