Overview

mavlink-camera-manager advertises camera names and RTSP stream URIs using the Mavlink camera protocol for use in QGroundControl. This allows you to use the camera selector drop down menu in the camera controls to choose an RTSP stream by camera name. The camera RTSP streams must already be setup using, for example, voxl-streamer

Prerequisites

An autopilot connection must already be established with QGroundControl otherwise it will ignore any cameras attempting to connect.
