This function processes the input file and returns packet by packet as an output data this packet is used in audio decoder component for decoding
copying the packetized data in the output buffer that will be decoded in the decoder component
return the current output buffer

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