I see that GPUVideoCamera utilizes AVCaptureSession (accessible as a property, (thank you)) and adds AVCaptureDeviceInput as an input, however I want to add GPUImageView (filtered video with higher contrast, etc) as an input to CaptureSession to optimize scanning QR codes that may have less than ideal contrast. \r\n\r\nKnowing that AVCaptureSession is expecting an AVCaptureInput, and not a GPUImageView, Is there a way to do this?\r\n\r\nFor context, these are what we're scanning:\r\nhttp://dataspacetime.com/qr/\r\n\r\nBest, \r\nRay"}}
