Redrawing depends on your application.
I use FLTK and there I just call redraw() functions for each window.
If your screen does not change during video, you can save the
framebuffer and restore it at the end.
This is what double buffering does in FLTK.

Actually, playing video is not inside a window. I have two graphics
plane, one is meant for RGB window which is used for framebuffer, and
another plane is used for video. (A shell command is invoked to play the
video)

You are correct. But playing a video on the other plane leaves the RGB
window corrupted. Here in this case I have to redraw the screen as it
was before.
Please let me know how to forcefully redraw everything.
