Constructor Detail
MovieExporter
public MovieExporter(int subType)
throws QTException
Opens the specified movie export component,'spit', with the given subType.
QuickTime::OpenADefaultComponent
Parameters:subType - The movie export component sub type
MovieExporter
public MovieExporter(ComponentIdentifier comp)
throws QTException
Given a component identifier it opens the specified component. The component type
must be 'spit' or an exception will be thrown as it is not a MovieExporter.
This constructor allows an application to find the appropriate export component
and then have that component opened.
QuickTime::OpenAComponent
Parameters:comp - the component identifier to open
