An object that supprts using Core Image filters to process an individual video frame in a video composition.
Mac Catalyst 13.0+
You use this class when creating a composition for Core Image filtering with the init(asset:applyingCIFiltersWithHandler:) method. In that method call, you provide a block to be called by AVFoundation as it processes each frame of video, and the block’s sole parameter is a AVAsynchronousCIImageFilteringRequest object. Use that object both to the video frame image to be filtered and allows you to return a filtered image to AVFoundation for display or export. Listing 1 shows an example of applying a filter to an asset.
