QuickTime Headers and Java Classes
As we've seen, Java classes are created from structures and data types found in the standard QuickTime C language header files. These provide the basic class structure of the QuickTime for Java API. The original QuickTime interfaces on the Mac OS are contained in a collection of eight header files that describe the standard QuickTime API. As such, nearly all of the functions defined in these files are to be found in classes in the
quicktime.std
group of packages.
The standard QuickTime C header files with their corresponding packages in the QuickTime for Java API are shown in
Table 2
.
