QMediaContent ¶

概要 ¶

详细描述 ¶

QMediaContent is used within the multimedia framework as the logical handle to media content. A QMediaContent object contains a QNetworkRequest which provides the URL of the content.

A non-null QMediaContent will always have a reference to the content available through the request() 方法。

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.
