requires free packet

[jhpark555]

It needs to be freeing the packet after ao_play. Otherwise the kernel becomes stack overflow.

	if(!ao_play(out_dev, resamples, howmuch)){
		printf("Could not play audio to output device...");
		goto retry;
	}

•            av_packet_unref(&pkt); 
  

  }
  CodecHandler_deinit(&codecHanlder);
  return (0);

Thanks for the pull request. However, are a lot of changes that were done by other authors; I think development has moved to @morningstar1 's repository.
