How to add custom filters on iOS ??

Hello, i need some help !!!

How could I add custom filters ?

and 1 more question:

Like add an layer over the capture and stream it with it… For example the drawings in Facebook live or Snapchat when recording a video… How i can do that ??


There is an example of a simple filter (black and white) in the sample app code here:

Look on line 434 for the videoFrameWasCaptured callback to see where you can access the captured frame and manipulate it.


Not sure about that
