class CPostProcessorInfo : public CBase;
Description
This class contains information about the post-processing functionality that a single post-processor or decoder hardware device
has. Although it mainly contains static data, it is defined as a complete CBase-derived class since the data is relatively
complex and proper memory management is necessary.
The objects are created by the post-processor or decoder devices, and used by the MSL video client code.
Derivation
CBase -
Base class for all classes to be instantiated on the heap.
