A demo project demonstrating how to add filter, drawing, and text to a video
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
