does anyone have any suggestions for fixing this?? i'm using the latest eclipse plugin's from wpi.

also i verified that the webcamera is working by plugging it into my laptop and viewing it.

thanks

Does the name of the camera that shows up on the roborio web interface match the one that is being supplied in the code? The name of the camera in the code is "cam0", but it may be something else. To find the name of the camera go to "roborio-xxxx.local/" in a web browser where the x is your team numbers, which would be "roborio-4905.local/" for you.
