[Live-devel] Get current playback position

[Warren Young]

We tried to find a way to get the current playback position in our 
live555MediaServer variant, but it looks like that's entirely internal 
to the library, not something we can access from the public class 
interface.  Basically we want to be able to call

	MPEG2TransportFileServerMediaSubsession::seekStream()

from outside the library, and for that, we need an NPT value.  As I 
understand it, the only safe place to get one is from the index file, 
which is owned by the internal ClientTrickPlayState class, and there is 
no public call that can give us its fNPT member.

Could we get this added to a future version of Live555, please?
