We expose a set of new elements: * ULPFEC encoder / decoder * A storage element, which should be placed before jitterbuffers, and is used to store packets in order to attempt reconstruction after the jitterbuffer has sent PacketLost events * RED encoder / decoder (RFC 2198), these are necessary to use FEC in webrtc, as browsers will propose and expect ulpfec packets to be wrapped in red packets With contributions from: Mathieu Duponchelle <mathieu@centricular.com> Sebastian Dröge <sebastian@centricular.com> https://bugzilla.gnome.org/show_bug.cgi?id=792696
