Protocol for a video session that can be processed frame by frame

This is a low level highlight processing session that can be used to process video frames one by one. You should obtain the video frame in any way you want and call processFrame method to process it. Sequence of calls to process the video:

• start() to start processing
• processFrame(buffer) for every frame of the video
• stop() to stop processing and finalize the results

Protocol to record a video with the rear camera.

Provides control over the recording process and camera preview. You can access the current state of the recording with status observable property.

The sequence of calls should be as follows:

• initVideoRecorder(orientation) (usually onAppear and orientation change) call to init the rear camera and start receiving the preview into the previewLayer
• startRecording() when the user presses the record button. This will start supplying the video frames to the recording session

When done:

• stopRecording() when the user presses the stop button. Recording stops but previewLayer continues to show the camera view
• stopVideoRecorder() (usually onDisappear) to stop the preview and shutdown the camera
