The Constructor of the video encoder component
| cComponentName | is the name of the constructed component |
we could create our own port structures here fixme maybe the base class could use a "port factory" function pointer?
Allocate Ports and call port constructor.
Domain specific section for the ports. first we set the parameter common to both formats
now it's time to know the video coding type of the component
general configuration irrespective of any video formats setting other parameters of omx_videoenc_component_private
initializing the coenc context etc that was done earlier by ffmpeglibinit function
