This is something that the *client* requests (using the RTSP 
protocol).  It does not require any special support from the server. 
I.e., our existing, unmodified server code can do this.

This is easy to do from your RTSP client (and, as I noted above, 
without requiring any modification to server code).  Note, for 
example, how the "openRTSP" demo application (a RTSP client) 
implements the "-s <initial-seek-time>" and "-d <duration>" options.

Again, this is easy to do - from the client.  Note, for example, how 
"openRTSP" implements the "-c" option.

See <http://www.live555.com/openRTSP/>, and the "openRTSP" source 
code (in "testProgs/playCommon.cpp").
