There are two points about implementing autofocus in userspace which I'm not sure about: * An autofocus daemon/program will need to have access to the video stream together with the program which uses the webcam. Is this possible? My experiments with luvcview and mplayer have failed, the second program always appears to get EBUSY. * Ideally, the autofocus should only be active when another program is actually using the camera, to avoid wasting CPU/power resources. What are your thoughts on how AF could be implemented? So far, my only idea is some kind of LD_PRELOAD hack, but that's ugly. :-/ Cheers, Richard -- __ _ |_) /| Richard Atterer | GnuPG key: 888354F7 | \/¯| http://atterer.net | 08A9 7B7D 3D13 3EF2 3D25 D157 79E6 F6DC 8883 54F7 ¯ '` ¯ _______________________________________________ Linux-uvc-devel mailing list [email protected] https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
