mjpg-streamer scripts for RoboRIO

This was very quickly put together... so not quite as polished as I would normally like. :) 

We used these scripts to run two camera servers on our roboRIO. Very little CPU usage as far as we can see. Only tested with the Microsoft LifeCam 3000 cameras.

Instructions


Download the tarballs at http://www.chiefdelphi.com/forums/showthread.php?p=1460637
scp them to the roborio
untar the tarballs in the home directory of the admin user
Copy the libjpeg*.so files into the mjpg-streamer-182 directory
Create the files in this gist in the mjpg-streamer-182 directory


Usage

If you run install.sh, it will cause two camera servers to start on startup. Obviously, you can edit it to only start a single server.

If you run run_one.sh, it will run a server on http://roborio-XXXX.local:5800 which you can access with a web browser and figure out how to use.
