push_video_context(3)		  Arcan Lua API 	   push_video_context(3)

NAME
     push_video_context  -  Store the current video context and make it unreach-
     able.

SYNOPSIS
     nil
     push_video_context()

DESCRIPTION
     All video objects are bound to (at least) one rendering context.  The  cur-
     rently  active  context  is managed on a stack. Pushing involves saving the
     current context on a stack, possibly deallocating data that can be reloaded
     or regenerated.

EXAMPLE
     function push_video_context0()
	   QSZ = math.floor(VRESW * 0.5);
	   a = fill_surface(QSZ, 255, 0, 0);
	   b = load_image("test.png");
	   c = load_movie("test.avi", FRAMESERVER_LOOP, function(s, state)
		 if (state.kind == "resized") then
		       play_movie(c);
		 end
	   end);
	   resize_image({b, c}, QSZ, QSZ);
	   show_image({a, b, c});
	   move_image(b, QSZ, 0);
	   move_image(c, 0, QSZ);
	   push_video_context();
	   pop_video_context();
     end
