Metrics for calculating sent/recv key frame rate:
num_encoded_frames -- number of encoded frames
num_decoded_frames -- number of decoded frames
num_send_key_frames -- number of sent keyframes
num_recv_key_frames -- number of received keyframes
Metrics for frame size (in bytes) distribution:
recv_key_frame_size_bytes -- key frame size
recv_delta_frame_size_bytes -- delta frame size
The stats are only reported if the user so requests. This is
because the stats may not be useful for regression tracking,
but mainly for adhoc analysis.
Tested:
```

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 here for instructions on how to get started developing with the native code.
