The Constructor for camera source component
| openmaxStandComp | is the pointer to the OMX component | |
| cComponentName | is the name of the constructed component |
Allocate camera component private structure
Init camera private parameters by default values
Allocate Ports.
this is the important thing separating this from the base class; size of the struct is for derived class port type this could be refactored as a smarter factory function instead?
Call base port constructor
Init port parameters by default values
set the function pointers
