Re: mjpg-streamer running on roboRIO

This package supports launching up to 4 instances of mjpg streamer (the second would be at :5801 instead of :5800). You'll need to edit /etc/default/mjpg-streamer on the roborio, followed by '/etc/init.d/mjpg-streamer restart' or a robot reboot to enable this.

Refer to the FMS Whitepaper for bandwidth approximations. Last year we were able to run two 120x160 streams at 10fps with no complaints from the FTAA (we doubled the display size of the image on our HTML dashboard).
