Re: Classmate Video Lagging

The lag is caused by sending more images than can be displayed. Images flow from the camera through its TCP stack, to the bridge, to the laptop and its stack. any buildup and it will start to lag.

If you watch the laptop CPU and identify the speed that it is displaying, you probably want to set the camera framerate to a value no faster. At that point, the laptop CPU should drop below max and the lag should reduce and minimize at a 100ms or so.

Updating the laptop or splitting the duties will allow for higher framerate without lag.

I also don't really see how this could cause a cRIO to reboot since the cRIO isn't at all involved in the display to the dashboard.
