Importing Movie Data

Movie data import components may provide one or two functions that allow the Movie Toolbox to request a data conversion operation. The MovieImportHandle function instructs your component to retrieve the data that is to be imported from a specified handle. The MovieImportFile function instructs you to retrieve the data from 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 Import Components" beginning on page 9-26 for more information about these functions). However, your component should work properly even if none of these configuration functions is called.
