## 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.

### QMediaContent::~QMediaContent()

Destroys the media content object.

### QNetworkRequest QMediaContent::canonicalRequest() const

Returns a QNetworkRequest that represents that canonical resource for this media content.

### QMediaResource QMediaContent::canonicalResource() const

Returns a QMediaResource that represents that canonical resource for this media content.

### QUrl QMediaContent::canonicalUrl() const

### bool QMediaContent::operator!=(const QMediaContent &other) const

Returns true if other is not equivalent to this media content; false otherwise.

### QMediaContent &QMediaContent::operator=(const QMediaContent &other)

Assigns the value of other to this media content.

### bool QMediaContent::operator==(const QMediaContent &other) const
