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.
