Common reasons (/excuses) to stay on the couch with WebRTC

• ORTC vs. WebRTC – I don’t want to pick the wrong side

• No one is using the same codecs (VP8 vs. H.264)

• Microsoft doesn’t support WebRTC

• Apple doesn’t support WebRTC

• I can keep using flash

• Standards aren’t done

• WebRTC is buggy

Standards convergeThe next version of WebRTC incorporates what’s new in ORTC while maintaining backward

compatibility with today’s WebRTC

What you can do with WebRTC 1.0 objects

• "Warm up" media path while the getting a track and ringing

• Change the send codec (without SDP munging)• Change the camera source instantly (front to back)• Enable/disable sending of media instantly (without

signalling)• Set a max bandwidth• Obtain detailed status of individual ICE and DTLS

Outcome: everybody wins

• H.264 install base camp got H.264 as a mandatory codec• Royalty free camp has set the path for a royalty free codec world in the future through the Alliance for Open Media

Everyone does H.264/AVC now.. mostly
