The document discusses the use of WebRTC, addressing common hesitations to adopt it, such as compatibility issues and lack of support from major companies like Microsoft and Apple. It highlights the integration of ORTC with WebRTC, along with advancements and the eventual standardization of web technologies for real-time communication. Despite bugs, WebRTC has seen significant adoption, indicating its robustness and widespread usage across billions of users.

3. 3
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

7. 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
transports

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
