iOS: Fix rotation bug for back camera

The rotation is currently incorrect for the back camera in landscape
mode. The reason is that device rotation needs to be reversed for the
back camera compared to the front camera. The camera sensor can also be
mounted with a specific orientation. So when front camera rotation goes
through: 0->90->180->270, back camera rotation goes in reverse:
180->90->0->270.

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.
