A problem in attributes for AVPlayerItemVideoOutput in LocalFileViewController

[madadoux]

in this declaration
when I make this code as it is

   lazy var playerItemVideoOutput: AVPlayerItemVideoOutput = {
        let attributes = [kCVPixelBufferPixelFormatTypeKey as String: Int(kCVPixelFormatType_32BGRA)]
        return AVPlayerItemVideoOutput(pixelBufferAttributes: attributes)
    }()

nothing is showin on the screen
I think It doesn't know how to make a texture from the CVPixelbuffer

but when I pass nil to the constructor

   lazy var playerItemVideoOutput: AVPlayerItemVideoOutput = {
        let attributes = [kCVPixelBufferPixelFormatTypeKey as String: Int(kCVPixelFormatType_32BGRA)]
        return AVPlayerItemVideoOutput(pixelBufferAttributes: nil)
    }()

it show like this
