This project demonstrates how to use CoreImage to add filter, drawing, and text to a video.

The flow is: 

- for every frame, get CVPixelBuffer from a AVCaptureSession, convert it to a CIImage instance

- add filter to the CIImage

- add drawing and text layer to the CIImage

- render the CIImage to the screen

- write the CIImage to the file
