Well, buffering is necessary, as media streams operate in a sort of 
pull/push mode where we can only send them samples if they have 
requested one with IMFMediaStream::RequestSample.  Also, appsink is just 
more convenient than manually setting up a pad, I've also considered 
changing the source pad to appsrc, but if it isn't broken....
