The Constructor
Allocate Ports and call port constructor.
for the moment, the file reader works with video component so the domain is set to video in future it may be assigned after checking the input file format or there can be seperate file reader of video component

The Initialization function
Video Capability Query
The pointer memoryMap and the offsets within memoryBuffer.offsets combine to give us the address of each buffered frame. For example: Buffered Frame 0 is located at: memoryMap + memoryBuffer.offsets[0] Buffered Frame 1 is located at: memoryMap + memoryBuffer.offsets[1] Buffered Frame 2 is located at: memoryMap + memoryBuffer.offsets[2] etc... The number of buffered frames is stored in memoryBuffer.frames.
