when view goes to background , capture session is getting nil and stop recording is not working

[chiragkukreja]

can anybody tell, why this is happening , when view goes to background , capture session is getting nil and stop recording is not working

i just debug the issue and found that
open func fileOutput(_ captureOutput: AVCaptureFileOutput, didFinishRecordingTo outputFileURL: URL, from connections: [AVCaptureConnection], error: Error?) is giving error

Error Domain=AVFoundationErrorDomain Code=-11818 "Recording Stopped" UserInfo={NSLocalizedDescription=Recording Stopped, AVErrorRecordingSuccessfullyFinishedKey=true, NSLocalizedRecoverySuggestion=Stop any other actions using the recording device and try again., NSUnderlyingError=0x1c084c1e0 {Error Domain=NSOSStatusErrorDomain Code=-16414 "(null)"}}

Hi,

A possible solution could be to set a notification for when the app moves to background to pause the captureSession (or do whatever you want to do) and then another notification to resume the captureSession (or whatever you want to do) when the app returns to foreground

i.e

NotificationCenter.default.addObserver(self, selector: #selector(appMovedToBackground), name: Notification.Name.UIApplicationWillResignActive, object: nil)

i tried the same thing but when u go background , this function
open func fileOutput(_ captureOutput: AVCaptureFileOutput, didFinishRecordingTo outputFileURL: URL, from connections: [AVCaptureConnection], error: Error?)
gets automatically called with error.

At the moment it's not possible for me to test on an iPad. Did you managed to identify the problem @Usman4Github ?
