AVURLAssetShouldSupportAliasDataReferencesKey
A Boolean value that indicates whether the system parses and resolves alias data references in the asset.
Declaration
let AVURLAssetShouldSupportAliasDataReferencesKey: StringDiscussion
Most QuickTime movie files contain all of the media data they require, but some contain references to media in other files. While AVFoundation and CoreMedia typically employ a URL reference for this purpose, older implementations commonly use a Macintosh alias instead, as the QuickTime File Format specification documents. Specify this option if your app must work with legacy QuickTime movie files that contain alias-based references to media data in other files.
If you provide a value for AVURLAssetReferenceRestrictionsKey, the system observes restrictions for resolved alias references like it does for URL references.
