The new observer replaced SetSessionDescriptionObserver for SetRemoteDescription. Unlike SetSessionDescriptionObserver, SetRemoteDescriptionObserverInterface is invoked synchronously so that the you can rely on the state of the PeerConnection to represent the result of the SetRemoteDescription call in the callback. The new observer succeeds or fails with an RTCError. This deprecates the need for PeerConnectionObserver::OnAdd/RemoveTrack and SetSessionDescriptionObserver, with the benefit that all media object changes can be processed in a single callback by the application in a synchronous callback. This will help Chromium keep objects in-sync across layers and threads in a non-racy and straight-forward way, see design doc (Proposal 2): https://docs.google.com/a/google.com/document/d/1-cDDC82mgU5zrHacfFz720p3xwRtuBkOPSRchh07Ho0/edit?usp=sharing An adapter for SetSessionDescriptionObserver is added to allow calling the old SetRemoteDescription signature and get the old behavior (OnSuccess/OnFailure callback in a Post) until third parties switch.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.
Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.
The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.
Development
See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.
