No - is overlay much faster?
I have two examples, one about using xlib to show images, and another, a webcam using gtk contributed . Dont know if it helps you... http://videodog.cjb.net | http://planeta.terra.com.br/informatica/gleicon
Thanks - I think xlib is a nice way to solve my problem.
choose code for the xlib example, or video4linux for the gtk example. in the latest videodog release, I've included the xlib example. I dont know how to use xvideo ... regards
