This is part of the work for making VideoStreamEncoder responsible for configuring its source/sink and limiting the responsibility of OveruseFrameDetectorResourceAdaptationModule to only output relevant VideoSourceRestrictions. BEFORE THIS CL Prior to this CL, OveruseFrameDetector was responsible for performing AddOrUpdateSink() on the source, which it did using its nested class VideoSourceProxy. AddOrUpdateSink() could happen for both adaptation and non-adaptation related reasons. For example: - Adaptation related: AdaptUp() or AdaptDown() happens, causing updated VideoSourceRestrictions. - Non-adaptation related: VideoStreamEncoder asks the module to reconfigure the source/sink for it, such as with SetMaxFramerateAndAlignment() or SetWantsRotationApplied(). AFTER THIS CL AddOrUpdateSink() is performed by VideoSourceController, which is owned by VideoStreamEncoder. Any reconfiguration has to go through the VideoStreamEncoder. This means that: - Non-adaptation related settings happen between VideoStreamEncoder and VideoSourceController directly (without going through the adaptation module). - Adaptation related changes can be expressed in terms of VideoSourceRestrictions. OveruseFrameDetectorResourceAdaptationModule only has to output the restrictions and not know or care about other source/sink settings. For now, VideoSourceController has to know about DegradationPreference. In a future CL, the DegradationPreference logic should move back to the adaptation module. The VideoSourceRestrictions are fully capable of expressing all possible source/sink values without the "modifier" that is the degradation preference.

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.
