I have mjpg_streamer working ok with my Yun and camera but I'm interested in customizing it for my video monitoring project. I have searched and haven't found instructions for how to do something like this on the Yun (i.e. build the package after customizing the source). Any pointers would be appreciated. The hacks I have in mind would likely be useful to others.
Alternately or in addition I'm thinking of some hacks to fswebcam that should be useful for monitoring too.
