Fix Opus stereo decoding of mono FEC to get trivial stereo output.

When a mono Opus encoder sends FEC, and a stereo decoder is used, the decoder can produce non-trivial stereo audio. This change adds logic to ensure that if the last received packet was mono encoded, the decoded output is forced to be trivial stereo when decoding in stereo mode. A new unit test is added to cover this scenario.

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.
