If you want a VideoCapture to be a member of the class, you don't want this in your class definition:

VideoCapture myCapture (string videoFileName /* :  I am not sur what to put here */ )  ;

Instead you want this:

VideoCapture myCapture;

Then, your constructor can do this:

myClass::myClass (string PLEASE_GIVE_ME_A_BETTER_NAME)
: myCapture(PLEASE_GIVE_ME_A_BETTER_NAME),
videoFileName(PLEASE_GIVE_ME_A_BETTER_NAME)
{
}
