Hi Tim,
	You should set aside enough buffer space to hold your data AND the extra padding to it and ensure that the extra padding is set to zero. Something like this would suffice :-

If you have copied the incoming data to your buffer, e.g memcpy(mPkt->data, data, dataSize);
Then you should pad it thus - memset(mPkt->data + mPkt->size, 0, FF_INPUT_BUFFER_PADDING_SIZE);

Or something similar depending on how you copy your incoming data to your own buffer, just ensure that the size of your buffer is big enough to hold your incoming data as well as the padding.
