It sets flags=2 for the last audio packet of a series of packets to be
unscrambled together, so that the first data to be returned from it
will have the keyframe flag set. However, this is not the first audio
packet in that series at the time when we were reading data from the
disk. I need the first packet for the seek to be useful in any way.
