| class CPreProcessorInfo : public CBase |
This class contains information about the pre-processing capabilities that an encoder or a pre-processor hardware 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 pre-processor or encoder devices, and used by the MSL video client code.
