GStreamer Motion Detector Plugin

================================

This is a simple GStreamer plugin that detects motion in a video

stream in a Gstreamer pipeline.  The element has one sink pad and

one source pad, both only support 24-bit RGB formats.

Connect the element inline with your video stream and either watch

the elements `notify::motion-detected` signal or watch for application

bus messages containing motion information.

The plugin uses OpenCV to find moving blobs against an averaged

background scene.  It's not super-robust but it's still quite

accurate.  You can tweak the element properties to improve detection

somewhat.

Here's a sample pipeline:

	$ gst-launch -v --gst-plugin-path=$PLUGIN_PATH \

          autovideosrc ! \

          video/x-raw-rgb ! \

          motiondetector draw_motion=true rate_limit=500 ! \

          ffmpegcolorspace ! \

          queue ! \
