我试图在AVCaptureConnection上设置像素格式类型，但它终止于所有RGB设置，但适用于kCVPixelFormatType_32BGRA

Terminating app due to uncaught exception 'NSInvalidArgumentException', 
reason: '*** -[AVCaptureVideoDataOutput setVideoSettings:] Unsupported 
pixel format type - use -availableVideoCVPixelFormatTypes'

产生此错误的代码如下：

let settings: [AnyHashable: Any] = [kCVPixelBufferPixelFormatTypeKey as AnyHashable: kCVPixelFormatType_30RGB]
output.videoSettings = settings as! [String : Any]

明白了

我查看了该相机上可用的像素格式，发现它只支持三种不同类型的像素格式

420f、BGRA和420v
