Not that I'm aware of, although an extension might be possible to support it. I know that other chips have ways to do conversion, although OGA may be the only design that only does it on the way in/out between the host and the graphics memory. Also, I get the impression that some video players bypass X11 and get direct access to the framebuffer somehow, and that won't be a problem here. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
