\preliminary
\brief The QMediaContent class provides access to the resources relating to a media content.
\ingroup multimedia
QMediaContent is used within the multimedia framework as the logical handle
to media content. A QMediaContent object is composed of one or more
\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.
