A dictionary of metadata to include in the Live Photo movie file.
Declaration
var livePhotoMovieMetadata: [AVMetadataItem]! { get set }Discussion
Live Photos capture both a still image and a short movie, which the system presents together in user interfaces such as the Photos app. A Live Photo movie always contains a AVMetadataQuickTimeMetadataKeyContentIdentifier key, associating the movie with a similar identifier in the kCGImagePropertyExifMakerNote property of the corresponding still image. The photo capture output automatically generates a unique content identifier for you if you don’t specify one of your own. You can also use this property to specify additional movie metadata.
This property applies only if the value of the livePhotoMovieFileURL property is to non-nil.
