+ \ingroup multimedia
+
+ QMediaContent is used within the multimedia framework as the logical handle

+ \l {QMediaResource}s where each resource provides the URL and format
+ information of a different encoding of the content.
+
+ A non-null QMediaContent will always have a primary or canonical reference to
+ the content available through the canonicalUrl() or canonicalResource()
+ methods, any additional resources are optional.
