OK to import this, now that I finally got this working? (grmbl grmbl stupid ioctl wrapper function using the wrong type for "request"...).
-- -- -- Description: Motion is a C program that monitors the video signal from one or more V4L2/video(4) cameras or network-based webcams, and is able to detect if a significant part of the picture has changed. Or in other words, it can detect motion. Motion is a command line based tool. It has absolutely no graphical user interface. Everything is setup either via the command line or via a set of configuration files (simple ASCII files that can be edited by any ASCII editor). Motion can output JPEG/PPM images and MPEG video sequences, call external programs, log to a database, etc. -- -- --
