        void onFrame​(VideoFrame frame,
                     ProcessedVideoFrameListener processedFrameListener)
        Called on a worker thread when a new frame is available from the local camera. It provides the possibility for developer to process the local video frames (e.g. applying filters on the frames), and send the updated video frames to the remote client. Updated frames are also shown on preview. The video frames are in YUV I420 planar or semi-planar (but not fully interleaved) format. ImageFormat.YUV_420_888
        Parameters:
        frame - The YUV I420 frame object.
        processedFrameListener - use it to inform that processing is complete and send frames (updated or original) to remote client

        IMPORTANT: When processing is complete, call onFrameProcessed() method of ProcessedVideoFrameListener interface. Failure to do so will lead to remote side not getting any frames. It is allowed to call processedFrameListener.onFrameProcessed() with either original or updated or entirely new frame. The call to onFrameProcessed() should be invoked from same thread as onFrame() callback.
