title: Using gstreamer to stream from Framebufferr via RTSP
body: <p>I have built GStreamer, GStreamer RTSP Server and some related plugins running streaming via RTSP. GStreamer RTSP Server examples can use some sources from webcam (dev/video0) with v4l2src, videotestsrc, or .MP4 file with filesrc. </p>
  
  <p>So, how can I stream from framebuffer source (dev/fb0) via RTSP?</p>
