Run the demo

• IoT CEP Demo - LeapMotion - Record — start LeapMotion controller application in record mode.

  • -record <path to output directory>

  • -fps <1-150> — transmit stream with the given frame per second

Note: The frame stream always be recorded with the maximum FPS available through Leap Motion controller. The -fps parameter only impact the publishing frequency to processing components.
