Detailed Description

A media resource is composed of a URL containing the location of the resource and a set of properties that describe the format of the resource. The properties provide a means to assess a resource without first attempting to load it, and in situations where media be represented by multiple alternative representations provide a means to select the appropriate resource.

Media made available by a remote services can often be available in multiple encodings or quality levels, this allows a client to select an appropriate resource based on considerations such as codecs supported, network bandwidth, and display constraints. QMediaResource includes information such as the MIME type , audio and video codecs, audio and video bit rates, and resolution so these constraints and others can be evaluated.

The only mandatory property of a QMediaResource is the url() .
