Description Rustam Zaitov 2016-09-08 13:57:01 UTC
AVCapturePhotoBracketSettings.FromRawPixelFormatType accepts NSDictionary<NSString, NSObject> for second parameter.
Header file has a clue with possible keys/values (see below). Header file states that AVVideoSettings(Compressed|Uncompressed) DictionaryContainers are possible here.

From header file:
 @method photoBracketSettingsWithRawPixelFormatType:processedFormat:bracketedSettings:
    Creates an instance of AVCapturePhotoBracketSettings.
 @param rawPixelFormatType
    One of the OSTypes contained in AVCapturePhotoOutput's -availableRawPhotoPixelFormatTypes array. May be set to 0 if you do not desire RAW capture.
 @param processedFormat
    A dictionary of Core Video pixel buffer attributes or AVVideoSettings, analogous to AVCaptureStillImageOutput's outputSettings property. If you wish an uncompressed format, your dictionary must contain kCVPixelBufferPixelFormatTypeKey, and the format specified must be present in AVCapturePhotoOutput's -availablePhotoPixelFormatTypes array. kCVPixelBufferPixelFormatTypeKey is the only supported key when expressing uncompressed output. If you wish a compressed format, your dictionary must contain AVVideoCodecKey and the codec specified must be present in AVCapturePhotoOutput's -availablePhotoCodecTypes array. If you are specifying a compressed format, the AVVideoQualityKey is also supported. If you only wish to capture RAW, you may pass a non-zero rawPixelFormatType and a nil processedFormat dictionary. If you pass a rawPixelFormatType of 0 AND a nil processedFormat dictionary, the default output of AVVideoCodecJPEG will be delivered.
 @param bracketedSettings
    An array of AVCaptureBracketedStillImageSettings objects (defined in AVCaptureStillImageOutput.h). All must be of the same type, either AVCaptureManualExposureBracketedStillImageSettings or AVCaptureAutoExposureBracketedStillImageSettings. bracketedSettings.count must be <= AVCapturePhotoOutput's -maxBracketedCapturePhotoCount.
    An instance of AVCapturePhotoBracketSettings.

    An NSInvalidArgumentException is thrown if bracketedSettings is nil, contains zero elements, or mixes and matches different subclasses of AVCaptureBracketedStillImageSettings.
    AVCapturePhotoBracketSettings do not support flashMode, autoStillImageStabilizationEnabled, livePhotoMovieFileURL or livePhotoMovieMetadata.

Any ETA on this one?
Comment 3 Rolf Bjarne Kvinge [MSFT] 2018-01-09 13:11:16 UTC
@Gabriel, this is only to add a more helpful overload, it won't make anything possible that isn't already possible, which means it probably won't fix the issue you mention in bug #61024.
