I don't think this is correct / accurate.
The point of the padding is not that you add 0's to 
the pkt->size number of bytes of your input data, 
but that you make sure that the buffer that contains 
the number of bytes is FF_INPUT_BUFFER_PADDING_SIZE 
larger than pkt->size (ie was allocated with at least 
pkt->size + FF_INPUT_BUFFER_PADDING_SIZE).
