We want to implement bookmarking:

    a) find out where the server is playing from right now;
    b) save that somewhere external to the server;
    c) at a later time, restart playback; and
    d) jump to the previous playback position.

This is simplified.  There could be any number of bookmarks, and the 
jump doesn't always immediately follow playback restart.  It's a form of 
trick play external to the RTSP conversation.

We asked for this feature in terms of NPT, since seekStream(NPT) already 
exists and is public.

We could modify the library to surface the fNPT member we found, but of 
course that isn't kosher, so we ask here instead.

For step a), I haven't yet studied whether the other parameters are easy 
to obtain as a client of the library.  If not, we'll need a way to find 
it/them, too.
