There is an example of a simple filter (black and white) in the sample app code here: [https://github.com/WowzaMediaSystems/gocoder-sdk-samples-ios/blob/master/SDKSampleApp/VideoPlayerViewController.m](https://github.com/WowzaMediaSystems/gocoder-sdk-samples-ios/blob/master/SDKSampleApp/VideoPlayerViewController.m) Look on line 434 for the videoFrameWasCaptured callback to see where you can access the captured frame and manipulate it.
