Live Camera Filter

So, I used the UIImagepickercontroller to access the camera for photo and video capture, then I wanted to apply filters for these two sources, I managed to filter tokens, but I have problems finding a solution for the rest, all I need to do is get access to raw image data: a live image that is displayed by the camera, apply a filter, and then display the filtered ones. Any help or advice would be appreciated.

UIImagePickerController does not provide low level access to the camera buffer.

You must configure AVCaptureSession and use a delegate to handle CMSampleBufferRef

Take a look at Apple's AVCam and SquareCam demos to give you a good idea of ​​video capture.
