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 \l {mimeType()}{MIME type}, \l {audioCodec()}{audio} - and \l {videoCodec()}{video} codecs, \l {audioBitRate()}{audio} and - \l {videoBitRate()}{video} bit rates, and \l {resolution()}{resolution} - so these constraints and others can be evaluated. - - The only mandatory property of a QMediaResource is the url(). - - \sa QMediaContent -*/ - -/*!
