“New protocol profile”

WebRTC standards

- Audio codecs – G.711, Opus - Video codecs – H.264, VP8 (oh, well…) - Media codecs are negotiated with SDP (for now at least) - Requires Secure RTP (SRTP) – DTLS-SRTP (SDES is prohibited) - Requires Peer-2-peer NAT traversal tools (STUN, TURN, ICE) – trickle ICE - Multiplexing: RTPs & RTP+RTCP - Tools for firewall traversal - DataChannel - Etc.
