This presentation was used in the context of a FI-WARE webminar for introducing Kurento. Kurento is a framework for building multimedia and streaming applications based on predefined blocks. Send and receive median through RTP, WebRTC, HTTP and RTSP. Use processing for making face detection, plate recognition or object tracking. Use augmented reality, group communications or media mixing and blending among others. During the webminar, we used Kurento APIs for showing how to create media applications for videoconferencing or video streaming in a simple and seamless manner. We also demonstrated how these applications can be enriched with Kurento's advanced processing capabilities.
