Question

I am working on Video based Application in Swift iOS. Where I am using AVPlayer to play the Video and setting

Answer 1

It seems like the CITemperatureAndTint filter is what you are looking for. I frankly don't know exactly how the parameters work, but maybe you can check out this or this related question.

Answer 2

Thanks @Frank Schlegel for direct me to CITemperatureAndTint Filter with inputNeutral and inputTargetNeutral. Please see the below Core Image Filter Parameter to get Warm and Cold tone effect :

filter = CIFilter(name: "CITemperatureAndTint")!

//cold

filter.setValue(CIVector(x: 16000, y: 1000), forKey: "inputNeutral")
filter.setValue(CIVector(x: 1000, y: 500), forKey: "inputTargetNeutral")

//warm

filter.setValue(CIVector(x: 6500, y: 500), forKey: "inputNeutral")
filter.setValue(CIVector(x: 1000, y: 630), forKey: "inputTargetNeutral")
