[Live-devel] How can I implement the action(such as Backward or Forward) on RTSP client?

To implement RTSP 'trick mode' operations (pause, seek, fast forward, 
reverse play) in VLC, support for each operation needs to be present in 
three places:

1/ In the VLC module ("vlc/modules/demux/livedotcom.cpp") that implements 
VLC's interface to the LIVE.COM RTSP client code.  (This code needs to 
handle the corresponding VLC GUI operations that do each 'trick mode' 
operation.)

2/ The LIVE.COM RTSP client code ("RTSPClient").

3/ The LIVE.COM RTSP server code - in particular, "RTSPServer", 
"ServerMediaSubsession", and its hierarchical subclasses 
"OnDemandServerMediaSubsession", "FileServerMediaSubsession" and 
"<codecName>FileServerMediaSubsession".

Looking at each of the 'trick mode' operations in turn:
- Pause is implemented in 2/ and 3/, but not yet in 1/
- Seek is implemented in 2/, but not yet in 1/ or 3/
- Fast forward and reverse play are not yet implemented in 1/, 2/ or 3/.

Of these tasks, the most difficult task would be to implement fast forward 
and reverse play in 3/
