Detailed Description
The QMediaContent class provides access to the resources relating to a media content.
QMediaContent is used within the multimedia framework as the logical handle to media content. A QMediaContent object is composed of one or more QMediaResources 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.
Alternatively QMediaContent can represent a playlist and contain a pointer to a valid QMediaPlaylist object. In this case URL is optional and can either be empty or point to the playlist URL.
