DirectShow filter for real-time mixing of video streams, pictures and texts
Overview
The WebRTC/RTP Server is a DirectShow Filter for sending media streams from the graph to the network. It gets encoded video or audio streams and send them by the network to peers wia WebRTC compatible protocols. The filter performs a renderer function and must be placed as a sink filter in the graph (the last filter in the graph chain).
