Drop frames until specified bitrate is achieved.

This CL fixes a regression introduced with the new quality scaler
where the video would no longer start in a scaled mode. This CL adds
code that compares incoming captured frames to the target bitrate,
and if they are found to be too large, they are dropped and sinkWants
set to a lower resolution. The number of dropped frames should be low
(0-4 in most cases) and should not introduce a noticeable delay, or
at least should be preferrable to having the first 2-4 seconds of video
have very low quality.

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. This page is maintained by the Google Chrome team.

Development

See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.
