An example shown here, where you send captured frame to HDMI output.

    "# OpenCV Filters Webcam\n",
    "\n",
    "In this notebook, several filters will be applied to webcam images.\n",
    "\n",
    "Those input sources and applied filters will then be displayed either directly in the notebook or on HDMI output.\n",
    "\n",
    "To run all cells in this notebook a webcam and HDMI output monitor are required.  "
   ]
  },

   "source": [
    "## 1. Start HDMI output \n",

Most of the examples given send just a single still frame, I want to send live video but can not seem to figure out how to do this from just looking at the still frame examples ? if you look at the code I posted I clearly marked where I am stuck …

By writing a while loop, you should be able to send out a live video? The example is doing that. Maybe the number of frames is small so it looks like a still frame to you?
