title: Do I need OpenCV build with Gstreamer to use Gstreamer in OpenCV
body: <p>I am trying to send <code>cv::Mat</code> frames via RTSP.
  I created a working project in Visual Studio using GStreamer using this <a href="https://github.com/GStreamer/gst-rtsp-server/blob/master/examples/test-video.c" rel="nofollow noreferrer">gst-rtsp-server</a> code. I am able to receive test video of GStreamer using VLC.</p>
  
  <p>Now I am trying to send a video via OpenCV by reading it frame by frame using <code>cv::VideoCapture</code></p>
  
  <p>But my OpenCV is built without GStreamer support? How can I use the GStreamer library to send Opencv frames via RTSP?</p>
