I apply tons of image processing to a camera live preview layer via OpenGL, and I want to get some information about the input`s orientation before I ask for the image from OpenGL (to apply corresponding transformations).
The capturing takes place in a portrait only viewController, and having notifications from the device orientation, or stuff may not be syncronized with the actual image orientation, I'm afraid.
Has CMSampleBuffer any orientation info? Or AVCaptureConnection?
