reducedResolution
A request to decode at a lower resolution than full-size.
Declaration
optional var reducedResolution: CGSize { get set }Discussion
This optional property conveys a request for reduced resolution for decoding. Decoders that only support a fixed set of resolutions should pick the smallest resolution greater than or equal to the requested width and height. If the output CVPixelBuffer is not in a format where reduced resolution decoding is supported, this setting should be disregarded. This property is set on the extension when a Video Toolbox client sets the kVTDecompressionPropertyKey_ReducedResolutionDecode property on the hosting VTDecompressionSession.
