Exporting Movie Data

Movie data export components may provide one or two functions that allow the Movie Toolbox to request a data conversion operation. The MovieExportToHandle function instructs your component to place the converted data into a specified handle. The MovieExportToFile function instructs you to put the data into a file. You should set the appropriate flags in your component's componentFlags field to indicate which of these functions your component supports. Note that your component may support both functions.

Before the Movie Toolbox calls one of these functions, a requesting application may call one or more of your component's configuration functions (see "Configuring Movie Data Export Components" beginning on page 9-37 for more information about these functions). However, your component should work properly even if none of these configuration functions is called.
