If metadata does not contain XMP properties belonging to the Dynamic Media scheme, the method returns null.

If the metadata does not have Dynamic Media XMP properties, and you need to add such properties, create a new instance of the com.accusoft.imagegear.formats.xmp.dynamicmedia.ImGearDynamicMediaXMPMetadata class, pass it to this method, and then add XMP properties using corresponding properties of the com.accusoft.imagegear.formats.xmp.dynamicmedia.ImGearDynamicMediaXMPMetadata class.

If you need to remove Dynamic Media XMP schema properties from the metadata, set this value to null.
