EncodedImageIdInjector is responsible for injection of frame id into
encoded image before it will be sent to the transport layer. It will
help to track video frame from capturing on 1st peer side to rendering
on 2nd peer side and will make it possible to calculate video quality
stats between these frames.
This CL also introduces two different implementations for injector:
1. DefaultEncodedImageIdInjector will prepend all encoded images with
extra data and then will restore them on another side. This injector
can work even if peers are running on different devices.
2. SingleProcessEncodedImageIdInjector can work only when all peers
are running in the same process, but won't use any extra data
to propagate frame id between peers, so it won't affect any
transport level metrics and bitrate estimator.
This CL is first part of new video quality analyzer for end-2-end
peer connection level test framework.

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.
