IOS：在横向模式下使用avcam进行视频录制？

我的应用程序在“常规->设备方向”设置中锁定为纵向模式

我正在使用AVCam录制视频，我想同时录制横向和纵向视频

我尝试过以下方法，也尝试过其他几种方法，但都无济于事：

当设备旋转时，我已设置预览层方向并开始录制视频

[[(AVCaptureVideoPreviewLayer *)[[self previewView] layer] connection] setVideoOrientation:(AVCaptureVideoOrientation)toInterfaceOrientation];

// Update the orientation on the movie file output video connection before starting recording.

[[[self movieFileOutput] connectionWithMediaType:AVMediaTypeVideo] setVideoOrientation:(AVCaptureVideoOrientation)[UIDevice currentDevice].orientation];

---

开始录制视频时设置当前设备方向

[[(AVCaptureVideoPreviewLayer *)[[self previewView] layer] connection] setVideoOrientation:(AVCaptureVideoOrientation)toInterfaceOrientation];

// Update the orientation on the movie file output video connection before starting recording.

[[[self movieFileOutput] connectionWithMediaType:AVMediaTypeVideo] setVideoOrientation:(AVCaptureVideoOrientation)[UIDevice currentDevice].orientation];

---

开始录制前，设置视频输出连接的视频方向

斯威夫特3

videoOutput.connection(withMediaType: AVMediaTypeVideo).videoOrientation = AVCaptureVideoOrientation(rawValue: UIDevice.current.orientation.rawValue)!

试试这个
