 I'd like to make one comment to the last argument (timestamp as
 indicator of dupped frames): that wouldn't be any different if the
 repeat field was implemented, it'd just be an *extra* measure for
 *constant* framerate streams to measure this. So both would be
 possible simultanoeusly.

+One alternative is for the source to push buffers pointing to the same
+data multiple times.  If the sink does not understand this little
+trick, it will use the buffers the same as if the buffers pointed to
+different data.  If it does understand this trick, it will recognize
+that the data for subsequent buffers is identical.
+
+Of course, this requires a bit of overhead, since both the source and
+sink need to have an additional buffer referenced at all times,
+thereby increasing average memory usage.  But any method will require
+additional memory usage.
