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
We will study programming aspects of the above with Java in the next Chapter.
