At the moment, no. You will need to modify WPIlib: (From AxisCamera.cpp)
Code:
// TODO: Keep track of this so it can be shut down!
new PCVideoServer();
But to answer your question, FRC_cameraTask and FRC_PCVideoServer
2.5 seconds is bad, did you update the driverstation to 1.1, cRIO to v20 and WPILib to 4.3?
