Super class: AVMovieMBS

Type Topic Plugin Version macOS Windows Linux Console & Web iOS
class AVMovie MBS AVFoundation Plugin 16.0 Yes No No Yes, macOS only No
Function: AVMutableMovie adds to its immutable superclass, AVMovie, several categories of methods for editing QuickTime movie files, e.g. inserting and removing time ranges of media, adding and removing tracks, and modifying the metadata collections stored therein.
Notes:
By default, after creating an AVMutableMovie the defaultMediaDataStorage property will be nil and each associated AVMutableMovieTrack's mediaDataStorage property will be nil. If you want to create an AVMutableMovie from a file and then append sample buffers to any of its tracks, you must first set one of these properties to indicate where the sample data should be written.
