> Original issue's description:
> > Add unit tests for RTCMTLVideoView.
> >
> > To properly test the functionality,  following changes  were needed
> > - Make RTCMTLVideoView compiliable for all cpu architectures not just arm64.
> > This is needed so that the test can run on any device and on simulator as well.
> > - Refactor RTCMTLVideoView to have  mockable class methods.
> > The unittest class, RTCMTLVideoViewTests was designed to provide easy transition
> > to XCTest when the time comes for that.
> > To transition to XCTest it would suffice to inherit from XCTestCase and remove
> > the gtest methods.

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.
