sequencegrabber.html

这个是java的quicktime for java 的详细使用文档

 The sequence grabber component stores the data that is obtained during the record operation 
 as a QuickTime movie in this file. This function also allows you to control some aspects 
 of the record operation, which are related to output, by specifying control flags.
