QuickTime Components

QuickTime includes several components that are provided by Apple. These components provide essential services to your application and to the managers that make up the QuickTime architecture. The following Apple-defined components are among those used by QuickTime:

movie controller components, which allow applications to play movies using a standard user interface
standard image-compression dialog components, which allow the user to specify the parameters for a compression operation by supplying a dialog box or a similar mechanism
image compressor components, which compress and decompress image data
sequence grabber components, which allow applications to preview and record video and sound data as QuickTime movies
video digitizer components, which allow applications to control video digitization by an external device
media data-exchange components, which allow applications to move various types of data in and out of a QuickTime movie
derived media handler components, which allow QuickTime to support new types of data in QuickTime movies
clock components, which provide timing services defined for QuickTime applications
preview components, which are used by the Movie Toolbox's standard file preview functions to display and create visual previews for files
sequence grabber components, which allow applications to obtain digitized data from sources that are external to a Macintosh computer
sequence grabber channel components, which manipulate captured data for a sequence grabber component
sequence grabber panel components, which allow sequence grabber components to obtain configuration information from the user for a particular sequence grabber channel component

These components and the interfaces they support are discussed in Inside Macintosh: QuickTime Components .
