How will you handle the permission model, what about devices where you need the V4L2 controls to take the picture in the first place ? It seems it should really be the same device and just a minor tweak to the API. V4L2 already provides frame reading and mapping functionality and the media layer provides post processing services which I could conceive some setups needing to use. gphoto would just open the v4l device ask for still image stuff and discover it wasn't available. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
