iPhone 16 takePicture() with ResolutionPreset.max and camera built-in_video:5 throw CameraException #156373
Description
Steps to reproduce
- create a new flutter project
flutter create example - copy the code from
samplecode to main.dart - update camera & microphone usage description in Info.plist
- build the project and run in real device iPhone 16 (iOS Version: 18.0)
- click the take picture button at bottom right
camera: ^0.11.0+2only camera com.apple.avfoundation.avcapturedevice.built-in_video:5 has problem.
It throws exception CameraException(Error -11800, The operation could not be completed).
Maybe we shouldn't use highResolutionPhotoEnabled in method captureToFileWithCompletion for latest iOS versions since it already deprecated and support up to iOS 16.0.
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 commentedon Oct 8, 2024
well, Code=-11800 is AVErrorUnknown
I have no clue for it so far...🫠
mkarapetyan-clgx commentedon Oct 16, 2024
It can be solved when you set ResolutionPreset non
.maxvalue, something like this:CameraController(camera, ResolutionPreset.veryHigh, imageFormatGroup: ImageFormatGroup.jpeg);NOTE: changing ResolutionPreset causes aspect ratio changes
ming-chu commentedon Oct 17, 2024
@mkarapetyan-clgx Yes, I used other
ResolutionPresetvalue as a workaround.But I think this is not a normal behavior to throw an exception when using
.max.Brysenp commentedon Oct 21, 2024
I'm able to replicate the issue reported by @ming-chu on an iPhone 16 Pro using the following camera package version:
Here are the relevant logs and Flutter doctor output:

Has there been any progress on this issue? I'd be happy to provide any additional information or assist with testing if needed.
ming-chu commentedon Oct 21, 2024
I thinks the highResolutionPhotoEnabled is already deprecated but we still using it. I am not sure if this is the root cause.

Brysenp commentedon Nov 5, 2024
I believe the issue was related to a bug in iOS 18. This bug seems to have been fixed in iOS 18.1.
@ming-chu, could you please confirm if this is correct?
ming-chu commentedon Nov 27, 2024
@Brysenp
I tested with
iOS 18.0.1 (22A3370)and still have error when taking photo with cameracom.apple.avfoundation.avcapturedevice.built-in_video:5Do you have any ideas?
jmagman commentedon Dec 20, 2024
@ming-chu Can you try on iOS 18.1, since that's the version @Brysenp is reporting it fixed in?
Ideally we would pass through a better error message, if nothing else.
I filed #160687 to audit for the deprecated APIs.

Without additional information, we are unfortunately not sure how to resolve this issue. We are therefore reluctantly going to close this bug for now.
If you find this problem please file a new issue with the same description, what happens, logs and the output of 'flutter doctor -v'. All system setups can be slightly different so it's always better to open new issues and reference the related ones.
Thanks for your contribution.
