在Windows 7中，QuickTime的PutMovieIntoTypedHandle间歇性崩溃是否有人遇到任何问题？
|
我最近继承了一个使用quicktime的代码库，我注意到使用它下面的函数导入动作在大多数情况下都是可行的，但有时会崩溃。它崩溃时很奇怪，因为它连续工作10次，然后崩溃了。
我在我的应用程序中使用C语言中的winapi。
IDE：Visual Studio 8
作业系统：Windows 7
Quicktime版本：最新
这是来自Quicktime API文档：
PutMovieIntoTypedHandle
拍摄电影或电影中的单个曲目，并将其转换为指定类型的句柄。
OSErr PutMovieIntoTypedHandle（
