iPhone 16 takePicture() with ResolutionPreset.max and camera `built-in_video:5` throw CameraException

[ming-chu]

Steps to reproduce

1. create a new flutter project flutter create example
2. copy the code from sample code to main.dart
3. update camera & microphone usage description in Info.plist
4. build the project and run in real device iPhone 16 (iOS Version: 18.0)
5. click the take picture button at bottom right

  camera: ^0.11.0+2

only camera com.apple.avfoundation.avcapturedevice.built-in_video:5 has problem. It throws exception CameraException(Error -11800, The operation could not be completed).

Maybe related code to set the preset on iOS platform: camera_avfoundation/ios/camera_avfoundation/Sources/camera_avfoundation/FLTCam.m

Error from objective-c code:

  // camera_avfoundation/ios/camera_avfoundation/Sources/camera_avfoundation/FLTCam.m

  __weak typeof(self) weakSelf = self;
  FLTSavePhotoDelegate *savePhotoDelegate = [[FLTSavePhotoDelegate alloc]
           initWithPath:path
                ioQueue:self.photoIOQueue
      completionHandler:^(NSString *_Nullable path, NSError *_Nullable error) {
        typeof(self) strongSelf = weakSelf;
        if (!strongSelf) return;
        dispatch_async(strongSelf.captureSessionQueue, ^{
          // cannot use the outter `strongSelf`
          typeof(self) strongSelf = weakSelf;
          if (!strongSelf) return;
          [strongSelf.inProgressSavePhotoDelegates removeObjectForKey:@(settings.uniqueID)];
        });

        NSLog(@">>> error: %@", error);
        if (error) {
          completion(nil, FlutterErrorFromNSError(error));
        } else {
          NSAssert(path, @"Path must not be nil if no error.");
          completion(path, nil);
        }
      }];

>>> error: Error Domain=AVFoundationErrorDomain Code=-11800 "The operation could not be completed" UserInfo={NSUnderlyingError=0x3031fe760 {Error Domain=NSOSStatusErrorDomain Code=-73720 "(null)"}, NSLocalizedFailureReason=An unknown error occurred (-73720), AVErrorRecordingFailureDomainKey=4, NSLocalizedDescription=The operation could not be completed}

Thank you for your tremendous help and contributions to the project!

Expected results

Expect return an image file after calling _contoller.takePicture() without exceptions.

Actual results

when calling _controller.takePicture() it throws exception CameraException(Error -11800, The operation could not be completed).

Thank you for the report! I don't have such a device to give this a test. Marking this as a device-specific issue for other's input.

[ming-chu]

well, Code=-11800 is AVErrorUnknown

I have no clue for it so far...🫠
