In addition it uses a GStreamerFilter configured to overlay the read text in the media stream. Finally, the KmsShowData is connected again to the same WebRtcEndpoint, closing the loopback. In the client side the WebRtcPeer is setup in receive-only mode, and the user is able to introduce text that is sent to the server by means of Data Channels Metadata. To run this demo follow these steps:
