+		True if decoder is allowed to output buffers matching reduced frame dimensions in the bitstream rather than
+		under-filling them.
+	@discussion
+		This is an optional property only supported by video decoders for bitstream formats which have a provision
+		for specifying output dimensions per-frame, such as AV1.
+
+		If a decoder does not support this property or if the property value is set to `kCFBooleanFalse`, all decoded
+		frames will have the same dimensions as specified in the format description. In this case, if the bitstream
+		changes the frame dimensions, the output buffer will be padded to the dimensions specified in the format
+		description.
+
+		When this property is set to `kCFBooleanTrue`, the decoder will set the dimensions of each output buffer to
+		match the dimensions specified in the bitstream for that frame.
+
+		In all cases, output buffer dimensions will never exceed the dimensions specified in the format description.
+
+		In apps linked to SDK versions before this property was added, the AV1 decoder will behave as if this property
+		is set to `kCFBooleanFalse`. Otherwise, value of this property defaults to `kCFBooleanTrue` where supported.
