I need to work on the framebuffer to record what is being rendered.

Now, I figure out how to convert the framebuffer in an image, I'm currently unable to obtain a constant stream of data from the fb to create a video.

/dev/fb > fb

When I do something like this my redirection just drops me and I honestly don't know how to work in another way with the framebuffer.

How I can obtain a stream?

/dev/fb is not a command! Use cat /dev/fb > fb – Guido May 29 '14 at 13:43
