We are using <math.h>, not <cmath>. While the latter defines additional overloads for abs(), including abs(float), they are not guaranteed to be available in <math.h>. libc++ ships its own math.h with the additional overloads, and libstdc++ (v6 or later) has a math.h that includes <cmath>, but this is not always expected to work: for example, GCC 5.x's libstdc++ does not have these additional overloads and causes the build to fail. Just use fabsf() from the C standard library directly, as it achieves the same thing in a more portable fashion.

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.
