rfbproxy is a program for recording, playback, and video conversion of Virtual Network Computing (VNC) screen sessions.

The heart of VNC is the RFB protocol, a simple network protocol to transmit an image of a computer's display, update the images as changes occur, and relay mouse and keyboard events. A VNC server maintains a desktop, which may correspond to a real physical computer display, or may be completely virtual, existing only in the computer's memory. VNC clients connecting to the VNC server can use this display as if it was their own, even though it may exist on another computer over the network. In this way, VNC is similar to Microsoft's Remote Desktop or Symantic's PCanywhere.

Yet the simple, open design of the RFB protocol, combined with VNC's support for multiple simultaneous clients, allows a client to unobtrusively connect to a VNC server and record the changing contents of its screen to a file, independent of any other activity on the desktop. This is the function of rfbproxy:

Since VNC server support is available for both X Windows and Microsoft Windows, this means you can use VNC and rfbproxy to record a UNIX X Windows or Microsoft Windows screen session, then either play it back or convert it to a MPEG, DivX, or Theora video. Since almost all computers also have soundcards, only a few more steps are required to couple audio with your video.
