Feature Request: Directory input of JPEG files
I have a web camera that on its own sends pictures via FTP to the machine that stores the individual picture files. This currently works quite well. What I am interested in is motion detection based on the directory. Each file name consists of a unique name (File prefix set in the camera, followed by a date time (to second) and a frame number). The camera sets the interval of sending the frames (in my case, I use 1 minute, but it can be more or less). I would like the motion program to "monitor" a directory and give output (email, whatever) when motion is detected.
I surmise that two modes would exist. The first would be a static analysis of the directory at a fixed time. It would output the change locations. The second would be a dynamic mode where it would look for new files to appear and difference them "on the fly". It would wait for new a new file, and compare it to the "previous" one (or more).
A secondary feature would be to "compile" the JPEG pictures into an MPEG movie while the processing is going on.
Example of the file name produced:
Prefix2009041614340001.jpg (Prefix%C%y%m%d%H%M%Sff.jpg, where ff is the frame number).
The Camera I am using is AirLink101 AIC250W
, but I suspect others will fit the bill.

You can use vloopback: http://www.lavrsen.dk/foswiki/bin/view/Motion/VideoFourLinuxLoopbackDevice
And vpipe: http://download.astronomix.org/vpipe-0.0.2.tgz
Basically make motion listen on a vloopback output and feed whatever you want into the vloopback input with vpipe.

anyone who could give a little more details of how to do this? perhaps the command for piping jpegs into the stream ?
