The QTPlgVideoDigitizerParam class is the super class of a set of classes that allows you to deal with different groups of parameters obtained from class instances. It implements properties and methods common to any video digitizer parameter whatsoever is its type; such a properties are suitable to describe the current capabilities and state information of the specified video digitizer parameter.
The QTPlgVideoDigitizerParam class constructors are called when you create a new instance of the class, while the ˜QTPlgVideoDigitizerParam class destructor, is called automatically when the class is no more in use. Also, you can invoke the class destructor by setting the instance of the class to nil.
You can not create valid instances of this class by yourself; instead, you can obtain valid QTPlgVideoDigitizerParam instances whether from dictionaries and by using the method of the class. You can inspect the capabilitites and state of the returned parameter and, if you need, change its state and then push back it to the video digitizer by using the class method.
Once a new class instance is returned, it is good practice to check the class property to be sure that the new object can be used.
The class provides you with the following initializer methods:
