Hi,
Whenever I try to initialize the camera using:
AxisCamera &axisCam = AxisCamera::GetInstance();
The robot starts to lag (The watchdog dies even with a 500ms timeout), and worst of all, the robot STILL does not send video to the dashboard
Yes we have the latest dashboard, crossover cable, camera set up properly. Any suggestions?
did you give the camera time to boot up fully before trying to use it in your code? if not it can hang the robot really easily, try adding a few waits before and after it
Where are you putting that in the code? I have it in Robot Init and it does not seem to slow anything down, and I get video. I have also noticed that the camera delays more with a low battery, so be sure to keep batteries fresh.
One thing we found about the camera is that if you don’t have communication with it, the GetInstance will take some time then timed out. The cause for us was that we used a wrong ethernet cable. You need a cross-over cable for the camera. We knew about the cross over cable requirement but we didn’t realize the cable we grabbed wasn’t cross-over. So make sure you label your cable correctly if you make your own.
Got it working, I changed the following:
Put camera init code in teleop, that way it waits a bit before starting, and I changed the camera subnet mask to 255.0.0.0
yeah, if the camera code hasn’t finished we found the same issuse of timeouts and other bad things happening to the robot (took a whole 1.5 hours of our testing time to figure out it was the camera 
). The problem seems to be WPILib’s internal handling of errors and their lack of a limiter on number of errors per second. It looks like the I/O gets overwhelmed and code slows down
