+	@abstract
+		This property requests that the decoder enable stricter bitstream validation.
+	@discussion
+		Setting this property to kCFBooleanTrue will request that the decoder enable additional strict bitstream conformance validation,
+		returning an error when non-compliance is detected.  Enabling this property may cause some samples which previously
+		played without visible issues to instead return an error on decode.
+
+		When an error is encountered, kVTVideoDecoderBadDataErr will be returned as the status
+		passed to the output callback or output handler.
