Hi everyone,

I'm newbie in Qt as well as OpenCV,
I have download the source code from
http://qt-apps.org/content/show.php/...?content=89995,
and execute this program,
it shows an " Assertion failed! "
and say:
Program:....
File: ..\QtOpenCV\main.cpp
Line:13
Expression: camera
For information on how your program can cause an assertion failure,
see the Visual C++ documentation on asserts
(Press Retry to debug the application - JIT must be enabled)

I don't know how to solve the problem, could you help me?
