ios - AVCapturePhotoCaptureDelegate Error When Capturing Image

Question

I seem to get this error message randomly after a few cycles of capture:

Error finishing photo: Error Domain=AVFoundationErrorDomain Code=-11800 "The operation could not be completed" UserInfo={NSLocalizedFailureReason=An unknown error occurred (-16802), NSLocalizedDescription=The operation could not be completed, NSUnderlyingError=0x281f20f30 {Error Domain=NSOSStatusErrorDomain Code=-16802 "(null)"}}

Error occurs in:

func photoOutput(_ output: AVCapturePhotoOutput, didFinishProcessingPhoto photo: AVCapturePhoto, error: Error?) {}

---

Notes:

• This Error never comes up on the first capture.
• The image format is also a processed format: HEIF
• iOS 13

有同样的问题，罪魁祸首是稳定。我在捕获图像时设置了 settings.isAutoStillImageStabilizationEnabled = true 。稳定是一个繁重的过程，它在主线程上阻碍了缓冲区分配。将其移至相机初始化的位置，为我解决了这个问题。
