从前置摄像头拍摄时总是看到镜像 iOS 5.0

从前置摄像头捕获数据时，我总是获得镜像，如何才能获得在预览窗口中看到的内容。我已将 videoMirrored 设置为 TRUE。以下是代码片段：

AVCaptureConnection *lConnection = nil;

  for ( AVCaptureConnection *connection in [lHandle->m_output connections]) {
     for ( AVCaptureInputPort *port in [connection inputPorts] ) {
         if ( [[port mediaType] isEqual:AVMediaTypeVideo] ) {
             lConnection = connection;
             break;
         }
     }
 }
if ([lConnection isVideoOrientationSupported])
    [lConnection setVideoOrientation:AVCaptureVideoOrientationPortrait];
if ([lConnection isVideoMirroringSupported])
    [lConnection setVideoMirrored:TRUE];

将 setVideoMirrored 更改为 True/False 也不会改变任何内容（isVideoMirroringSupported 返回成功）

While capturing data from Front camera I am always getting Mirror image, how can I get what I am seeing in my preview window. I have set videoMirrored to be TRUE. Following is the code snippet:

AVCaptureConnection *lConnection = nil;

  for ( AVCaptureConnection *connection in [lHandle->m_output connections]) {
     for ( AVCaptureInputPort *port in [connection inputPorts] ) {
         if ( [[port mediaType] isEqual:AVMediaTypeVideo] ) {
             lConnection = connection;
             break;
         }
     }
 }
if ([lConnection isVideoOrientationSupported])
    [lConnection setVideoOrientation:AVCaptureVideoOrientationPortrait];
if ([lConnection isVideoMirroringSupported])
    [lConnection setVideoMirrored:TRUE];

Changing setVideoMirrored to True/False also doesn't change anything
(isVideoMirroringSupported returns Success)

使用以下代码翻转镜像。

UIImage * flippedImage = [UIImage imageWithCGImage:picture.CGImage scale:picture.scale orientation:UIImageOrientationLeftMirrored];

Flip the mirrored image with the following code.

UIImage * flippedImage = [UIImage imageWithCGImage:picture.CGImage scale:picture.scale orientation:UIImageOrientationLeftMirrored];

Swift 版本：

let flippedImage = UIImage(CGImage: image.CGImage, scale: image.scale, orientation: .LeftMirrored)

Swift version:

let flippedImage = UIImage(CGImage: image.CGImage, scale: image.scale, orientation: .LeftMirrored)

您可以使用withHorizontallyFlippedOrientation()来翻转UIImage。

// first get an UIImage from the front camera
let sourceImg = UIImage(cgImage: image, scale: 1.0, orientation: .leftMirrored)
return sourceImg.withHorizontallyFlippedOrientation()

You can use the withHorizontallyFlippedOrientation() to flip an UIImage.

// first get an UIImage from the front camera
let sourceImg = UIImage(cgImage: image, scale: 1.0, orientation: .leftMirrored)
return sourceImg.withHorizontallyFlippedOrientation()
