AVPlayerItemVideoOutput.copyPixelBuffer fails with EXC_BAD_ACCESS

I've that function:

func retrievePixelBufferToDraw() -> CVPixelBuffer? {
  let time = self.playerItem!.currentTime()

  // this line is just added to make sure I can call something on self.videoOutput!
  self.videoOutput!.hasNewPixelBuffer(forItemTime: time)

  // raises EXC_BAD_ACCESS
  let pixelBuffer = self.videoOutput!.copyPixelBuffer(forItemTime: time, itemTimeForDisplay: nil)
  return pixelBuffer
}

It sounds like EXC_BAD_ACCESS comes from accessing deallocated variables, but I don't really see how that'd come into play here since I've checked all the variables I'm using before calling the line that fails.

Simple.. Your AVPlayer is not getting video input at same time it is throwing the error EXC_BAD_ACCESS Try to give it QuickTimeMovie when you are playing (player.play()) always require video input.

At the end player should not be nill(without proper playerItem)
