Warning
The string values returned by the MediaEncodingSubtypes properties may not use the same letter casing as AudioEncodingProperties.Subtype, VideoEncodingProperties.Subtype, ContainerEncodingProperties.Subtype, and ImageEncodingProperties.Subtype. For this reason, if you compare the values, you should use a case-insensitive comparison or use hardcoded strings that match the casing returned by the encoding properties.
