Is it possible ?

I'm using Gnome, pygtk, X11

I need save all live of my application to a video

Answer 1

Periodically use Window.get_snapshot to get snapshots of the window. Then compose these images into a video. A simple though inefficient mechanism I can think of to do this is for each frame, convert your Pixmap into a Pixbuf using Pixbuf.get_from_drawable. Then use Pixbuf.save to save each frame to a PNG. When the application has finished, compose all of these PNGs into a video using FFmpeg.
