Another thing is the overlay framebuffer. I think it's mainly useful to display video streams.
Right. The idea is that you can push a video stream into /dev/fb1 (for example by using the gstreamer fbdev sink) while displaying widgets from a GUI toolkit on /dev/fb0.
Maybe it's better to implement this as a v4l device as unlike the framebuffer API the v4l API is designed to handle different image buffers.
Huh? v4l is image-frames-to-userspace, not vice versa. rsc -- Pengutronix e.K. | | Industrial Linux Solutions | http://www.pengutronix.de/ | Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 |
