for each new input buffer --- copy buffer content into into ogg sync state structure data
pcm is a multichannel float vector. In stereo, for example, pcm[0] is left, and pcm[1] is right. samples is the size of each channel. Convert the float values (-1.<=range<=1.) to whatever PCM format and write it out

The Constructor
| cComponentName | is the name of the component to be initialized |
we could create our own port structures here fixme maybe the base class could use a "port factory" function pointer?
Domain specific section for the ports.
first we set the parameter common to both formats common parameters related to input port
Allocate Ports and call port constructor.
common parameters related to output port
settings of output port output is pcm audo format - so set the pcm mode settings
some more component private structure initialization
increase the counter of initialized components and check against the maximum limit
now it's time to know the audio coding type of the component if audio coding type is set other than vorbis then error returned
IL client specified an invalid component name
