Works e.g. in conjunction with Parrot Drones where the autopilot is the Paparazzi autopilot. Sends a RTP/UDP stream of the camera image, a.k.a. live video
Add to your firmware section: This example contains all possible configuration options, not all of them are mandatory!
These initialization functions are called once on startup.
