I need to create iOS class in swift for video editing.
So the class will record from device camera and audio from mic.
Needed functions as following:
1. duplicate frames
2. remove frames
3. add wax effect on specific frame
4. add canonized effect on specific frame
5. function to return all frames of recorded video
6. add audio
7. remove audio
8. keep original mic recorded audio
finally can save output video to photo library.
