Inside Macintosh: QuickTime Components

Configuring a Movie Data Exchange Component

You do not need to configure a movie data exchange component before you use it to convert data into or out of a QuickTime movie. These components are implemented in such a way that they can operate successfully using their own default configuration information. In fact, some data exchange components do not allow you to configure them. However, most data exchange components do support some or all of the configuration functions that are defined for components of this type.

If you are going to configure a data exchange component, you must do so before you start the data exchange operation. You must call the component directly in order to set the configuration--the Movie Toolbox does not do this for you. Use the functions described in "Configuring Movie Data Import Components" and "Configuring Movie Data Export Components," as appropriate. Note that all of these functions are optional; that is, it is up to the developer of the component to decide whether or not to support a given configuration function. If the component does not support a function you have called, the component returns an error code of badComponentSelector .
