From 1894293d6378c69548d974d2965e9decc1527654 Mon Sep 17 00:00:00 2001 From: Matthew Waters Date: Tue, 31 Jan 2017 20:56:59 +1100 Subject: webrtcbin: an element that handles the transport aspects of webrtc connections SDP's are generated and consumed according to the W3C PeerConnection API available from https://www.w3.org/TR/webrtc/ The SDP is either created initially from the connected sink pads/attached transceivers as in the case of generating an offer or intersected with the connected sink pads/attached transceivers as in the case for creating an answer. In both cases, the rtp payloaded streams sent by the peer are exposed as separate src pads. The implementation supports trickle ICE, RTCP muxing, reduced size RTCP.
