Yes, you need to drop down to the X11 layer. You can ask for a list of visuals which your server supports, pick out the RGB565 one, then send an image (optionally over XShm to avoid a copy) directly in that format. Of course then your player will only work for displays with an RGB 565 visual :-( Are you using X11? If you are using directfb it's all different. You could look at SDL as well I guess, though I've not used that myself. For a desktop machine, gdk_draw_rgb_image() should be fast enough, even with the extra coonversions.
