Application Architecture and filter development ideas

Some Application architecture :
--------------------------------------
Client - Wrap the VLC player in a Client application and control it.
Server - wrap the ffmpeg and control it using server application
we can broadcast the things with Server and receive the things with client
RTSP Application Architecture
------------------------------
RTSP Client : wrap the live555 RTSP receiving.
RTSP server: Wrap the live555 server
