Detailed Description

QMediaContent is used within the multimedia system as the logical handle to media content. A QMediaContent object is composed of one or more QMediaResource 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.
