    /*
     * This is the receiving end of an UDP RTP stream. The sender can be setup with this command:
     *
     * gst-launch-1.0 uvch264src initial-bitrate=1000000 average-bitrate=1000000 iframe-period=1000 name=src auto-start=true src.vidsrc ! \
     * video/x-h264,width=1280,height=720,framerate=24/1 ! h264parse ! rtph264pay ! udpsink host=192.168.1.9 port=5000
     *
     * Where the main parameters are:
     *
     *  uvch264src:         Your h264 video source (the example above uses a Logitech C920 on an Raspberry PI 2+ or Odroid C1
     *  host=192.168.1.9    This is the IP address of QGC. You can use Avahi/Zeroconf to find QGC using the "_qgroundcontrol._udp" service.
     *
     * Advanced settings (you should probably read the gstreamer documentation before changing these):
     *
     * initial-bitrate=1000000 average-bitrate=1000000
     * The bit rate to use. The greater, the better quality at the cost of higher bandwidth.
     *
     * width=1280,height=720,framerate=24/1
     * The video resolution and frame rate. This depends on the camera used.
     *
     * iframe-period=1000
     * Interval between iFrames. The greater the interval the lesser bandwidth at the cost of a longer time to recover from lost packets.
     *
     * Do not change anything else unless you know what you are doing. Any other change will require a matching change on the receiving end.
     *
