Here's my code:

func captureOutput(_ output: AVCaptureOutput, 
     didOutput sampleBuffer: CMSampleBuffer, 
            from connection: AVCaptureConnection) {

    guard CMSampleBufferDataIsReady(sampleBuffer) else { return }

    // This is the delegate method for 
    // AVCaptureVideoDataOutputSampleBufferDelegate and 
    // AVCaptureAudioDataOutputSampleBufferDelegate  
}

I'm trying to use Vision framework and draw a layer over eyes where I got the success. However I want to record the same.

Are you trying to Add the CALayer and save the video or image ? I've implemented face detect and masking the face with recording of it. – Tushar Katyal Aug 06 '19 at 11:54
Something like that, but I want to work at the lowest level possible, as close as I can to the buffer – Roi Mulia Aug 06 '19 at 12:14
Ah, i used CIDetector to detect faces and add a mask – Tushar Katyal Aug 06 '19 at 12:15
If i put that code, it'll make you confuse. letme see if i can upload it to github. – Tushar Katyal Aug 06 '19 at 12:16
