Hello everyone,
  I am trying to obtain a snapshot of the output of an application that draws 
using hardware accelerated Xv. The application is a video player and uses YUV 
format to display and SDL - it draws using SDL_DisplayYUVOverlay function. I 
want to grab a certain snapshot and place it in another window. I tried to 
use XvGetStill but all it gives me is black output. What should be done? Is 
there any way to get that picture from the overlay to X in a window?
  Thank you,
     Dorin Lazar
